Abstract
This practicality discloses a kind of counterflow-preventing scalp acupuncture, including syringe needle and needle stand, is connected by woven hose between the syringe needle and needle stand, and counterflow-preventing valve is provided in the needle stand, and counterflow-preventing valve forms a unidirectional infusion channel opened to syringe needle outbound course；The blood backflow occurred when can effectively prevent taking needle using the utility model can preferably protect medical staff and patient, while mode of operation does not have any difference with existing scalp acupuncture, conducive to being widely applied.
Description
Technical field
The utility model is related to technical field of medical equipment, and in particular to a kind of counterflow-preventing scalp acupuncture.
Background technology
In the prior art, usually blood back can be caused excessive because of a variety of causes in infusion, and by scalp and infusion apparatus
When being detached, it is easy to happen blood backflow phenomenon, and then cause safety accident.
The Chinese utility model patent of Publication No. CN203342136U disclosed a kind of primary on December 18th, 2013
Property practicality counterflow-preventing bushing type intravenous infusion needle, including sheath assembly and draw point component, which is characterized in that further include dual anti-reverse
Flow valve, Anti-stabbing safety device, Needleless barotropic connector, wherein the dual counterflow-preventing valve using preceding counterflow-preventing valve and
The front and back coaxial arrangement composition of counterflow-preventing valve afterwards.
The utility model can effectively avoid the problem that blood backflow is brought, and improve the working efficiency and peace of medical staff
Quan Xing.
Invention content
The defect of adverse current is easy to happen when being detached with infusion device for scalp acupuncture existing in the prior art, this practicality is new
Type discloses a kind of counterflow-preventing scalp acupuncture, and the utility model counterflow-preventing effect is good, can be carried out to patient and medical staff good
Protection.
The utility model is achieved through the following technical solutions above-mentioned purpose：
A kind of counterflow-preventing scalp acupuncture, including syringe needle and needle stand, the syringe needle are connected with needle stand by woven hose, and feature exists
In：Counterflow-preventing valve is provided in the needle stand, the counterflow-preventing valve forms the half-duplex channel opened to syringe needle outbound course.
The counterflow-preventing valve shares two panels, and the root of the counterflow-preventing valve is connected with needle stand, two panels counterflow-preventing valve
Head be oppositely arranged, and in " people " font be closed.
The thickness of the root of the counterflow-preventing valve is 0.3mm-0.6mm, and the head thickness of counterflow-preventing valve is 0mm-
0.15mm, the length of counterflow-preventing valve are 1.5-2 times of needle stand radius.
The counterflow-preventing valve is made of pharmaceutical grade PVC material.
The counterflow-preventing valve and needle stand position integrated formed structure.
Compared with prior art, the utility model has the advantages that：
1, it is provided with counterflow-preventing valve in the needle stand of the utility model, it is only defeated to syringe needle by counterflow-preventing valve formation one
The half-duplex channel that outgoing direction is opened, when there is the liquid reflux of negative direction, counterflow-preventing valve is closed automatically, closing volume channel,
Liquid reflux is prevented to reach, avoids the generation of air embolism, reaction speed is fast, simple in structure, is conducive to large-scale popularization.
2, the counterflow-preventing valve of the utility model shares two panels, and closure is tighter, and improving prevents liquid reflux
The root of effect, counterflow-preventing valve is connected with needle stand, and the head of two panels counterflow-preventing valve is oppositely arranged, and is closed in " people " font
It closes, improves the seal after valve is closed, improve the effect for preventing liquid reflux.
3, the thickness of the root of counterflow-preventing valve described in the utility model is 0.3-0.5mm, and the thickness on head is 0mm-
0.15mm, the thickness by thickening root improve bonding strength between counterflow-preventing valve and needle stand, counterflow-preventing valve are avoided to fall off；
The amplitude of fluctuation of head in a liquid can then be improved by reducing the thickness on head, and the quick-make on head, raising is convenient for prevent liquid
The technique effect of body reflux, the length of counterflow-preventing valve are 1.5-2 times of needle stand radius, then can improve two panels counterflow-preventing valve
Leakproofness after closure.
4, counterflow-preventing valve described in the utility model uses medical PVC material, improves the safety that transfusion needle uses, and leads to
It crosses counterflow-preventing valve and is integrally formed the structural strength and reliability that manufacture improves connection with needle stand.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Reference numeral：1, syringe needle, 2, needle stand, 3, woven hose, 4, counterflow-preventing valve.
Specific implementation mode
It below will the utility model is described in further detail by specific embodiment：
Embodiment 1
Most preferred embodiment of the present embodiment as the utility model, it discloses a kind of counterflow-preventing scalp acupunctures, such as Fig. 1 institutes
Show, including syringe needle 1 and needle stand 2, the syringe needle 1 connects 3 with needle stand 2 by woven hose, and counterflow-preventing valve is provided in the needle stand 2
Film 4, the counterflow-preventing valve 4 share two panels, and the root of counterflow-preventing valve 4 is connected with needle stand 2, the head of two panels counterflow-preventing valve 4
Portion is then oppositely arranged, formed by the opening and closing of two panels counterflow-preventing valve 4 opened to 1 outbound course of syringe needle it is unidirectional logical
Road.
The thickness of the root of the counterflow-preventing valve 4 is 0.6mm, and the head thickness of counterflow-preventing valve 4 is 0.15mm, anti-reverse
The length for flowing valve 4 is 2 times of needle stand radius.
The counterflow-preventing valve 4 is made of pharmaceutical grade PVC material.
The counterflow-preventing valve 4 and needle stand position integrated formed structure.
Embodiment 2
The root thickness of counterflow-preventing valve 4 described in the present embodiment is 0.6mm, and the head thickness of counterflow-preventing valve 4 is
0.15mm, the length of counterflow-preventing valve 4 are 2 times of needle stand radius.
The utility model forms one to the unidirectional of syringe needle outbound course opening by the unlatching of counterflow-preventing valve with closure
Channel achievees the purpose that prevent liquid reflux, have the characteristics that it is simple in structure, be swift in response, counterflow-preventing effect it is good, while this
The operating method of utility model and the operating method of existing equipment are completely the same, popularization it is of low cost, there is preferable application
