Abstract
The utility model provides a pressurizing gas injection pipe for infusion, comprising a needle head 1, a casing pipe 2 and an air inlet pipe 4. The utility model is characterized in that a one-way valve 3 is arranged on one end of the air inlet pipe 4 explored into the casing pipe 2, and a filter layer 7 is arranged between the one-way valve 3 and the inlet of the air inlet pipe 4. The utility model has the advantages of easy use, safety, compact structure and low manufacture cost.
Description
This utility model belongs to medical instruments field.Transfusion is usually used in rescuing critical patients such as craniocerebral injury, cerebrovascular disease clinically fast.Usually, in the process of implementing transfusion fast, the nursing staff often adopts behind the large size needle tubing suction air syringe needle is thrust the means of infusion bottle gas injection pressurization in bottle, owing to need continuous gas injection pressurization in infusion process, the repeated localised puncture bottle stopper very easily pollutes.This method does not have air purification equipment simultaneously, certainly will be with in the impurity band people institute transfusions such as airborne grit.
For addressing the above problem, people have proposed some technical schemes, by every means for example by a kind of " the infuse external pressue device " of Patent Office of the People's Republic of China in Granted publication in January nineteen ninety-five in recent years.This device is made up of air bag sebific duct, anti-skidding duroplasts joint, unidirectional shutoff valve, Murphy type burette, plastic tube and anti-slip joint, the two ends that it is characterized in that said anti-skidding duroplasts joint are respectively equipped with anti-foxy, the anti-slippery fellow of both sides is joined with rubber tube and unidirectional shutoff valve respectively, the other end and the air bag of rubber tube join, the other end of anti-skidding hard plastic tube is in unidirectional shutoff valve is sleeved on an end of Murphy type burette, and the other end of Murphy type burette joins by a plastic tube and an anti-slippery fellow.This technical scheme cooperates with the air siphunculus of transfusion device in the prior art in use.By the air bag pressurization, the medicinal liquid in the infusion bottle is splashed in the dropper on request.But because technique scheme is not examined the ad hoc air purification equipment of filter.And cotton balls is used in the filter of transfusion device air siphunculus of the prior art only, is unsuitable for gas-pressurized again and flows, so in use be difficult to finish to being pressed into gas cleaning; Simultaneously because this device volume is bigger, (especially air bag) thereby manufacturing cost height not only, and be not easy to packing and transportation; In use this device leans on the syringe needle of transfusion device to cooperate suspension with the infusion bottle bottle stopper with transfusion device composition one, and the danger of falling under the syringe needle and coming off is also arranged.
The purpose of this utility model is to overcome the deficiency of technique scheme, and the disposable pressure transfusion air injection pipe of a kind of compact conformation, easy to use, safe, low cost of manufacture is provided.
Figure of description 1 is a structural representation of the present utility model; 1-syringe needle in the accompanying drawing, 2-sleeve pipe, 3-check valve, 4-air inlet pipe, 5-taper hole, 6-boss, 7-filtering layer.
As shown in the figure, nonrecoverable pressure transfusion gas injection provided by the utility model Pipe comprises syringe needle 1, the sleeve pipe 2 that joins with syringe needle 1, is positioned at sleeve pipe 2 other ends Air inlet pipe 4, it is characterized in that: air inlet pipe 4 probes on the end in the sleeve pipe 2 and arranges Check valve 3 is arranged, a filtering layer 7 is set between the entrance of check valve 3 and air inlet pipe 4.
The version of check valve 3 can be done multiple choices, for example known diaphragm type or ball-valve type structure and in one section structure that the body both sides process an opposite joint of top closure.The preferred check valve of this utility model (3) is made up of one section silicone rubber tube of head portion sealing, and it can be made with air inlet pipe 4 one, also can be used as its part bonding with it (clamping) together.
Another characteristics of the present utility model are: the inlet inwall of air inlet pipe 4 is made the conical surface that can cooperate with needle tubing with normal injection; And that the inlet outer wall of air inlet pipe 4 can be made with the hand air bag is equipped with groove or boss.
This utility model is as disposable product, after sterilizing, pack and dispatch from the factory, syringe needle 1 thrusts in the infusion bottle during use, general infusion set uses according to a conventional method, in case of necessity can be in pressure process with the breather blocking-up of general infusion set, to insert air inlet pipe 4 middle gas injection pressurizations in infusion bottle behind the injection needle suction air of routine; The capsule that also can select for use sphygomanometer to use connects with the boss or the groove fit of air inlet pipe 4 inlet outer walls, and extruding gasbag pressurizes in infusion bottle.
The utility model has the advantages that: compact conformation, little, the low cost of manufacture, easy to use, safe of volume.
