Abstract
The invention relates to a two-channel transfusion head of automatically controlling liquid and gas to be transfused by time phases. The two-channel transfusion head comprises an independently used transfusion head body or at least two transfusion head bodies serially connected for use. A pure gas channel and a pure liquid channel are arranged in each transfusion head body, wherein the top end of each pure gas channel is open; the bottom end of each pure gas channel is provided with a floating valve chest communicated with the bottom end of the pure gas channel; a floating valve which vertically floats is arranged in the floating valve chest; one side of each floating valve chest is communicated with a gas/liquid inlet; the top end of each pure liquid channel is also open; the bottom end of each pure liquid channel is communicated with a gas/liquid outlet; and the bottom part of each pure liquid channel is also communicated with the bottom end of the corresponding floating valve chest. According to the two-channel transfusion head of automatically controlling the liquid and the gas to be transfused by time phases, the goal that the liquid and the gas pass through the transfusion head by time phases and by channels is realized; automatic control is realized during the whole process; the goal that multiple bottles of liquid can be connected in series to be continuously transfused is achieved, and therefore, the problem that liquids are mixed when the multiple bottles of liquid are connected in series to be continuously transfused is avoided, bottle replacing operations of nurses can be reduced, and the labor strength of the nurses can be relieved.
Description
Technical field
The present invention relates to the medical infusion utensil, refer in particular to the double passage transfusion head that a kind of automatic control liquid, gas timesharing are inputted mutually.
Background technology
Present transfusion head is a strict simple mechanism of distinguishing liquid, gas passage, there are many inconvenience, as: 1, because its integral body can not be mixed by liquid and gas, so it can only carry out the transfusion operation of single bottle of liquid, can not carry out continuous transfusion to many bottles of liquid series connection.2, owing to its gas, fluid passage do not separate, will cause infusion medicine to mix when carrying out by force many bottles of liquid series connection continuous transfusions, thereby cause malpractice.
Summary of the invention
The objective of the invention is provides a kind of automatic control liquid of many bottles of liquid series connection continuous transfusions, double passage transfusion head that the gas timesharing is inputted mutually realized for the shortcoming that exists in the background technology and problem improvement and bring new ideas in addition.
The present invention constructs the transfusion head that a kind of polypropylene cap of inserting infusion bottle or transfusion bag is carried out the liquid input, comprises independent use or at least two transfusion bodies that series connection is used, and in the transfusion body simple gas passage and simple liquid passage is set, wherein:
Simple gas passage top is uncovered, and the unsteady valve box that communicates is established in the bottom, the indoor upper and lower unsteady unsteady valve that arranges of valve that floats, and valve box's one side of floating is communicated with gas, liquid inlet;
Described simple liquid passage top also is uncovered, and the bottom is communicated with gas, liquid outlet, and the simple liquid channel bottom also communicates with bottom, unsteady valve box.
The present invention has the following advantages and beneficial effect:
The present invention has realized that liquid, gas timesharing phase, subchannel pass through the purpose of transfusion head, whole process implementation automatic control, realized can the connect purpose of continuous transfusion of many bottles of liquid, the problem of liquid mixing when having avoided many bottles of liquid series connection continuous transfusions, the bottle that changes that can reduce the nurse operates, and alleviates nurse's labor intensity.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention inserts the polypropylene cap of infusion bottle or transfusion bag and carries out the liquid input, comprises independent use or at least two transfusion bodies 9 that series connection is used, a transfusion body 9 interior simple gas passage 6 and the simple liquid passages 7 of arranging, wherein:
Described simple liquid passage 7 tops also are uncovered, and the bottom is communicated with gas, liquid outlet 2, and simple liquid passage 7 bottoms also communicate with 3 bottoms, unsteady valve box.
Gas of the present invention, liquid inlet 1 interior gas sink the valve 4 that floats, and gas is through simple gas passage 6 access infusion bottle or transfusion bag, and the liquid in infusion bottle or the transfusion bag is connected to the trouble body through simple liquid passage 7 and gas, liquid outlet 2 synchronously.Described gas, liquid inlet 1 interior liquid make valve 4 come-ups of floating, and liquid is connected to the trouble body through gas, liquid outlet 2.A described transfusion body 9 uses its gas, liquid inlet 1 to be the gas inlet port separately, and gas, liquid outlet 2 connect infusion needle.9 at least two series connection of a described transfusion body use the gas of its first transfusion body 9, liquid inlet 1 to be the gas inlet port, gas, the liquid outlet 2 of an end transfusion body 9 connect infusion needle, and gas, liquid inlet 1 and the gas of a middle transfusion body 9, liquid outlet 2 series connection form the continuous transfusion structure.A described transfusion body 9 outer setting have handle 8.In described simple liquid passage 7 bottoms and the passage that 3 bottoms, unsteady valve box communicate counterflow-preventing lobe 5 can be set, counterflow-preventing lobe 5 is one-way cock, is set to liquid can only be flow to by counterflow-preventing lobe 5 gas, liquid outlet 2 by the valve box 3 of floating structure.
Operation principle of the present invention:
When the front end infusion fluid, the come-up of valve 4 in the valve box 3 of floating realizes that the liquid that flows through in gas, the liquid inlet 1 arrives gas, liquid outlet 2 by passage by floating; When front end input gas, realize that by the sinking of valve 4 in the valve box 3 of floating of floating the gas that flows through in gas, the liquid inlet 1 passes through simple gas passage 6 in infusion bottle, and make the liquid in the infusion bottle arrive gases, liquid outlet 2 through simple liquid passage 7, wherein can by arrange counterflow-preventing lobe 5 be used for prevent that liquid from flowing to the valve box 3 of floating.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design philosophy of the present invention; engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
