Abstract
The invention discloses a catheter system for newborns and the department of pediatrics. The catheter system comprises an embedded body, wherein the front end of the embedded body is connected with an air guide pipe and an injection liquid catheter, wherein the air guide pipe is connected with an air inlet through an air pressure control valve, the injection liquid catheter is connected with an injection device through a flow rate control valve, the rear end of the embedded body is connected with a bent catheter, the bent catheter is connected with a contact head through a ball bag, a flow meter and a pressure sensor are arranged in the cavity of the ball bag, the flow meter is electrically connected with the flow rate control valve, and the pressure sensor is electrically connected with the air pressure control valve. The catheter system is simple in structure, the pressure inside the catheter can be monitored in real time b the structure of the pressure sensor in the ball bag, so that air introduction and discharge can be realized by controlling the air pressure control valve, so that the situation that the catheter breaks due to too large pressure inside the catheter, or the treatment effect can not be achieved due to too small pressure inside the catheter, is avoided.
Description
Technical field
The present invention relates to technical field of medical equipment, be specially a kind of neonate and pediatric catheter system.
Background technology
Neonate and pediatric catheter system play very important effect in medical domain, it is one of most desired Safety pipeline carrying out venous transfusion and treatment for a long time, the longest in vivo can indwelling 1 year, but conduit in use often occurs damaged because some are unexpected, once conduit breakage directly can have influence on the treatment of infant, increase the financial burden of infant family, even cause medical tangle.
Summary of the invention
The object of the present invention is to provide a kind of neonate and pediatric catheter system, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme: a kind of neonate and pediatric catheter system, comprise chimera, described chimeric front end is connected to airway and injection conduit, described airway is positioned at the top of injection conduit, described airway is connected with air inlet by pneumatic control valve, described injection conduit is connected with injection device by flow control valve, described chimeric rear end is connected with bending conduit, described bending conduit is connected with contact head by sacculus, the inner chamber of described sacculus is provided with effusion meter and pressure transducer, described effusion meter is electrically connected flow control valve, described pressure transducer is electrically connected pneumatic control valve.
Preferably, described injection device is be not less than the syringe of 10 milliliters.
Preferably, described chimeric surface is also provided with paste for fixing connecting conduct.
Preferably, described bending conduit is made up of 3 to 5 ductules, and the diameter of ductule is 0.5 to 2 millimeter.
Preferably, described sacculus is two-chamber single saccule conduit, and the diameter of sacculus is 5 to 10 millimeters.
Compared with prior art, the invention has the beneficial effects as follows: this neonate and pediatric catheter system structure simple, can be monitored the pressure in conduit in real time by the structure adding pressure transducer in balloon lumen, and then control pneumatic control valve carries out air inlet or gives vent to anger, prevent because make catheter rupture in conduit because pressure is excessive or do not reach therapeutic effect because pressure is too small, and add effusion meter in balloon lumen, monitoring feedback can be carried out in real time to the flow of injecting fluid in mozzle, thus the flow of institute's injecting fluid is controlled by flow control valve, prevent liquid infusion too much according to become blocking or liquid infusion very few and do not reach therapeutic effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is principle of the invention block diagram.
In figure: 1 air inlet, 2 pneumatic control valves, 3 airways, 4 chimeras, 5 injection devices, 6 flow control valves, 7 injection conduits, 8 bending conduit, 9 sacculus, 10 effusion meters, 11 pressure transducers, 12 contact heads.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1-2, the invention provides a kind of technical scheme: a kind of neonate and pediatric catheter system, comprise chimera 4, the front end of chimera 4 is connected to airway 3 and injection conduit 7, the surface of chimera 4 is also provided with paste for fixing connecting conduct, can be fixed conduit in use by catheter anchoring system, when preventing baby or child from crying and screaming, conduit is touched brokenly or the position of conduit is moved, thus do not reach the effect for the treatment of, airway 3 is positioned at the top of injection conduit 7, airway 3 is connected with air inlet 1 by pneumatic control valve 2, injection conduit 7 is connected with injection device 5 by flow control valve 6, the syringe of injection device 5 for being not less than 10 milliliters, this type of syringe can prevent pressure excessive and cause catheter injury, the rear end of chimera 4 is connected with bending conduit 8, bending conduit 8 is made up of 3 to 5 ductules, and the diameter of ductule is 0.5 to 2 millimeter, bending conduit 8 is connected with contact head 12 by sacculus 9, the inner chamber of sacculus 9 is provided with effusion meter 10 and pressure transducer 11, effusion meter 10 is electrically connected flow control valve 6, pressure transducer 11 is electrically connected pneumatic control valve 2, can be monitored the pressure in conduit in real time by the structure adding pressure transducer 11 at the inner chamber of sacculus 9, and then control pneumatic control valve 2 carries out air inlet or gives vent to anger, prevent because make catheter rupture in conduit because pressure is excessive or do not reach therapeutic effect because pressure is too small, and add effusion meter 10 at the inner chamber of sacculus 9, monitoring feedback can be carried out in real time to the flow of injecting fluid in mozzle, thus the flow of institute's injecting fluid is controlled by flow control valve 6, prevent liquid infusion too much according to become blocking or liquid infusion very few and do not reach therapeutic effect, sacculus 9 is two-chamber single saccule conduit, and the diameter of sacculus 9 is 5 to 10 millimeters.
Although illustrate and describe embodiments of the invention, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments without departing from the principles and spirit of the present invention, scope of the present invention is by claims and equivalents thereof.
