CN2812952Y - Anti-counter flow hand pressing quickening infusion connecting tube - Google Patents

Abstract

The utility model relates to a hand quick transfusion connecting pipe which can be prevented from flowing inversely in the process of the transfusion. The middle part of the connecting pipe is provided with a pressurization saccule having elasticity and reversion. An inverse flow prevention pipe on a liquid inlet pipe is inwards arranged in the pressurization saccule, and an inverse flow prevention pipe on a liquid outlet pipe is inwards arranged in a saccule funnel. The pressurization saccule is connected with the liquid inlet pipe and the liquid outlet pipe. The normal transfusion can be carried out, and simultaneously, the fast transfusion can be carried out when necessary. When the transfusion is completed, the condition that blood flows back to block a puncture needle head can be prevented.

Description

The anti-adverse current manual pressure connection tube of infusing fast

Affiliated technical field

This utility model belongs to the medical apparatus technical scope, relates to a kind of fast connection tube device of transfusion that pressurizes, the manual pressure that especially can the prevent adverse current connection tube of infusing fast.

Background technology

At present, used quick infusion set, be technology content than higher quick infusion pump or the quick transfusion device of pressurization that constitutes by the very complicated valve for preventing reverse-flow of structure, moreover be that a traditional interior pressurization of bottle or a bag external pressure infused fast, not only equipment complexity but also expense height, and simple pressure transfusion method is because the intermittence of its existence or dangerous and extra kit and can not produce a desired effect, particularly in critical patient's transportation, drawback more apparent during rescue is infinite, to such an extent as to delay treatment opportunity, lose and rescue or the surgical engine meeting, cause suffering or economic loss to the patient.

Summary of the invention

In order to overcome intermittence and the dangerous drawback that the high and simple pressure transfusion method of existing quick infusion set equipment complexity and expense exists, this utility model provides a kind of anti-adverse current manual pressure connection tube of infusing fast, this connection tube can reach manually the purpose of transfusion fast, prevent liquid return in pressure process, can free-handly operate, and in infusion process, can stop transfusion automatically, prevent that blood from refluxing, and stops up puncture needle in case transfusion finishes.

The purpose of this utility model is realized by following technical scheme: the middle part of transfusion connection tube is provided with a pressurization sacculus with elastic recovery, anti-reverse stream pipe on the feed tube is built in the pressurization sacculus, anti-reverse stream pipe on the drain pipe is built in the sacculus funnel, and the pressurization sacculus links to each other with drain pipe with feed tube.During with hands extruding sacculus, the output of CF body when hands loosens, utilizes the elastic recovery of sacculus, the full pressurization of liquid sacculus, and adverse current is not accelerated transfusion speed mutually.

The beneficial effects of the utility model are, can infuse fast in case of necessity in normal infusion, can prevent from also that blood from refluxing to stop up piercing needle, cause when continuing transfusion and puncture again, increase extra misery and financial burden to the patient.This connection tube adopts high-quality PVC material, and what anti-reverse stream pipe adopted is the guaranteed milk glue material, and rational in infrastructure, technology is simple.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified

Accompanying drawing is the longitudinal section of present embodiment

1. transfusion device connection tubes among the figure, 2. feed tube, the 3. anti-reverse stream pipe of feed tube, 4. pressurization sacculus, 5. anti-reverse stream pipe, 6. sacculus funnel, 7. drain pipe, 8. puncture needle connector of drain pipe.

The specific embodiment

The connector (1) of infusing in the drawings connects the tube for transfusion far-end, fills with liquid in the sacculus (4) that pressurizes after the aerofluxus, and puncture needle connector (8) connects the thorn syringe needle of threading a needle.When with hands extruding pressurization sacculus (4), intracapsular pressure is a malleation, and feed tube prevent that reverse stream pipe (3) closes, and drain pipe prevent reverse stream pipe (5) opening, and liquid is exported; When hands loosened, because the elastic recovery of pressurization sacculus, intracapsular pressure was a negative pressure, and drain pipe prevent that reverse stream pipe (5) closes, and feed tube is prevented reverse stream pipe (3) opening, and liquid fills sacculus.

This utility model modern design, rational in infrastructure, easy to use, be convenient to patient and in infusion process, operate, and prevent blood backflow obstruction syringe needle.

Claims (2)

1. anti-adverse current manual pressure connection tube of infusing fast, this connection tube comprises a pressurization sacculus and two anti-reverse stream pipes, it is characterized in that: the pressurization sacculus at connection tube middle part links to each other with drain pipe with the feed tube that is provided with anti-reverse stream pipe respectively.

2. the anti-adverse current manual pressure according to claim 1 connection tube of infusing fast, it is characterized in that the infusing middle part of connection tube is provided with a pressurization sacculus with elastic recovery, anti-reverse stream pipe on the feed tube is built in the pressurization sacculus, anti-reverse stream pipe on the drain pipe is built in the sacculus funnel, and the pressurization sacculus links to each other with drain pipe with feed tube.
