vThis invention has to do with a uid handling unit and apparatus, and is particularly concerned with a unit for collecting, storing, transporting and administering Huids, such as whole blood or plasma, or the like, in a safe, .efficient and sterile manner that eliminates the danger of contamination, breakage and other handling problems.

In hospitals, laboratories, doctors offices or4 like places, it is common practice to extract and to administer whole blood or plasma from or to persons being treated. In the handling of such fluids it is not only necessary to handle a supply thereof, but it is also necessary to take separate samples of the uid being handled so that various tests such as those for cross-matching of blood can be 'made in order'to determine the nature or type of uid being handled. Therefore, it is necessary to associate or identify the test sample with the supply'of uid handled so that the proper sample is always associated and identified with the supply of uid taken.

It is an object of this invention to provide a viluid handling unit and apparatus particularly useful for handling whole blood so that it can be storedin a container that is integrally associated with a sample container of the same whole blood, to the end that the storage container and the sampling container are'never separated thus avoiding danger of loss or confusion as to the type of blood when cross-matching the blood samples.

lt'is also an object of this invention to provide a unit and apparatus of the character referred to which includes supplemental uid containers in the form of fracturable or rupturable capsules, or the like, which contain anticoagulants, preservatives, or other saline solutions adapted to act upon the fluid in the container which is provided.

It is also an object of this invention to provide a unit and apparatus of the character referred to which provides an easily manipulated means which is adapted to be used particularly in cases of emergency when pressure infusion is desired, and the infusion or withdrawal of uid from a person may be expedited without subjecting the person to the danger of air embolism.

It is another object of this invention to provide a unit and apparatus of the character referred to which provides a simple and easily manipulated means for pumping the containers, either to fill or to exhaust uidthere'from.

A further object of this invention is to provide a unit of the character referred to vwhich is convertible in its use, to be useful either as a pressure apparatus or a vacuum apparatus. With the structure of the present invention the infusion or withdrawal of blood may be forced by a simple and easily manipulated means for pumping the containers or the administering or withdrawing of blood may be done under pressure.

It is still another object of this invention to provide a unit and apparatus to be used in the collecting, storing, transporting and administering of whole blood or plasma and which is adapted to be used in connection with a Igt4-mw Patented Aug. 12, 19,58

In accordance with the present invention the several parts of the unit X are integrally joined, that is, the several parts are permanently fastened together so that they cannot become separated. It will be apparent from the drawings that the several parts of uid handling unit X, formed-and related as shown, are such that they can be easily and practically molded or otherwise suitably for'med from a suitable plastic material, such as polyethylene or modifications thereof such as fluorinated polyethylene or chlorinated polyethylene, or various polyvinyl compounds may be used, either acetates, alcohols or chlorides, etc. The particular material or composition used in any particular case may be selected in accordance with the conditions to be met. The materials mentioned are thermo-plastics and are essentially inert at the temperatures required for the class of use indicated. Further, they are capable of being worked or formed by extrusion, injection 'or compression molding or by deposition on forms from dispersions known as plastisols or from solutions in some instances. Furthermore, it is practical to employ a material which can be molded hot so that the formation of the unit X serves to sterilize the elements thereof and may, in practice, supplement initial sterilization which may -be resorted to as circumstances require.

It is to be understood, of course, that although material such as polyethylene or polyvinyl is referred to as the material out of which to form the several parts of the unit X, it is not to be implied that the invention is limited to the use of this or any other particular material, and when the term plastic is used all other materials or combinations of materials are meant to be included within such term that may serve to carry out the inventive concept herein s et forth.

The carrier or vessel Y to which the unit X is to Ibe applied or to be inserted into may be a plunger operated and, for example, may be of a size or capacity to hold syringe-type container but is preferably a simple jar or 500 cubic centimeters of fluid. bottle shaped vessel. As shown in the drawings, the The fluid sampling container C, which may be revessel Y has a cylindrical outer wall 10, a circular bottom ferred to as a pilot, is a cell-like structure or bag, like 11 joining the outer wall at the lower end of the vessel 5 the container B, and is also characterized by a continua top 12 joining the outer wall at the upper end of the ous iinperforate wall 3@ of supple inert hlm-like matevessel, and a neck portion 13 projecting upwardly from rial, such as a vinyl plastic material.

As shown in Figs. l and 2 of the draw- 60 anc'l 60, ings, the container B is a closed cell having an extension tainers 60 and 60 are held between the sealed or joined a ends of the containers. With such an arrangement and from the container B. In preferred practice the fluid relationship 0f parts, initial app' storing container B is initially collapsed as shown in the cell, say at the rear end thereof as indicated by the Fig. l of the drawings and is inflatable as shown in Fig. 2 75 arrows in Fig. l will break the containers and liberate the lcontents thereof so that it mixes or co-,mingles with the contents of the containers. Itwill be apparent, 'however, that by suitable handling of the device the secondary containers- 60 and 60', when employed, need not be fractured or ruptured but can be fractured at any desired time, as circumstances require.

The means F provided for checking the flow of atmosphere to or from the ,vessel Y involves, generally, a simple check valve adapted to control the flow of atmosphere through the head A into or out of the interior of thevessel Y as circumstances require. yIn the preferred form of the invention where a exible vessel or squeeze bottle is employed a vent or port 37 is provided that extends through the head A from the top22 to the bottom 23 thereof, which port is somewhat tapered. When gravity and/ or venous pressure o-f the patient is employed to fill a container the port 37 is left open to allow for free flow of atmosphere from the vessel Y Or, when blood is: being given to a patient the vessel Y .may be elevated and inverted so that gravity acts to aid the liow of fluid whereupon the port 37 allows for free llow of atmosphere into the vessel Y.

A reversible valve body 38 is provided which has like tapered end portions 39 and 40 engageable in the port 37. Either end of the valve body 38 may be engaged in the port 37 so that the valve is carriedin sealed engagement with the head A.v The valve body 38 has a seat, and a valve. element 41 engages the seat checking the llow through the valve body so that the flow can occurin one direction only. It will be readily understood that when it is desired to exhaust the atmosphere from the vessel Y, it is merely necessary to arrange the valve body 38 :so that liow will occur therethrough in a direction to permit air. to be removed from the vessel and so that it cannot re-enter the vessel. When it is desired to pressurize the interior of the vessel Y, it is merely necessary to reverse the valve so that it is in a .position opposite to that above referred to. When a flexible vessel Y is employed it is a simple matter to gain the desired pumping action by manipulation of the cylindrical wall i0 of the vessel, as illustrated by the arrows in Fig, 2 ofthe drawings.

In the form of the invention shown in Figs. 6 and 7 of the drawings, a rigid vessel or substantially rigid vessel Y is employed and a separate pumping means is provided in the form of a bulb 4Z for pressurizing atmosphere Within the vessel. may be connected with the interior -of the vessel Y through a exible tubing or hose, which hose may be provided with a vtapered end portion engageable in the port 37. A valve body 38 is provided, which body Ahas like end portions 39 and 40 engageable in the bulb and the hose respectively. The body 38 has a seat, and a valve element 41' engages the seat checking the flow through the .body 38 so that flow occurs in one directiononly. the invention the valve body 38 is also provided with another seat and a valve element k41 which checks ow from the flow passage that extends through the valve body. The valve element 41 `checks .flow from `the valve body at one `end thereof as shown, so that a pumping action is obtained when the bulb 42 is manipulated to 'force air into the vessel Y as desired. It will be understood that the valve body 38 and the elements therein may be made to be reversed Or arranged in an opposite manner in order to vacuumize the vessel, if so desired.

In accordance with the present invention, a protector H is provided which closes the chamber 26 to the end that the fluid handling elements of the unit X are prevented from coming into contact with foreign objects. That is, the seals E are enclosed in the chamber 26 and are covered by the protector H which may be a simple sheet-like element 70 joined to the end `of the tubular extension 25. In practice, the element 70 is releasably joined to the extension 25 by means of an adhesive and may be removed by lifting a tab 71 with the fingers and may be re-applied to the extension 25 when desired.

--In Fig. 6 of the'drawings there is illustrated a modified formy of vblooddonor setl ,or unit S that involves generally apair of oppositely disposed needles N and a tubular body 50'. The-.tubular body 50 is closed at'. its ends -and-.is'preferably .a vrigid member forming a fluid handling jchamber. The needles N are tubularfparts and .arerigidly fastened to the ends of the body 50 topi-oject therefrom and are both in direct communication with theinterior of the chamber V80. In order to use vthe blood donor zset S it isv merely necessary to insert lone of the needles Npinto.the sealing means E, above ydescribed, whereupon the `otherzneedle N is adapted to be directly engaged withthe patient. As shown, the chamber is filled with a pack of suitable filtering material .so that the fluid lpassingzthrough'the device is cleaned of .any blood clots or foreign particles.

Fromthe foregoing it will be apparent that theiiuid handling unit X isa simple, inexpensive, sterile structure that can be easily applied to a'vessel Y and which can be utilized ,to aid'inthe extraction or administering of fluid, such. as Whole blood or plasma to or from apatent. The pilot orfsamplecontainer C, which is permanently attached tothe storing container B, is always adjacent the said storing container so that cross matching or other testing of `the pilot or sample is always associated or identified with .the-.fluid carried in the storing container.

It will ,also 'be understood from the foregoing, that the apparatusprovided can be inverted and held in an elevated position by means of a bail secured to the vessel Yzto administer'blood by force of gravity, and it will also be .apparent that in emergencies or when it is otherwise desired, it is a simple matter to speed up the ow of blood by manual manipulation ofthe apparatus provided.
