Abstract

A disposable pricking prevention device for a needle head comprises a needle cap, a puncture needle, a handle, a needle handle seat and a liquid guide hose; the puncture needle is fixed at the upper end of the needle handle seat; the liquid guide hose is fixed at the lower end of the needle handle seat hermetically; a handle is arranged on a side surface of the needle handle seat; the needle cap is sleeved on the puncture needle; a sliding sheath is arranged on the liquid guide hose; and a sliding opening used for the handle to pass through conveniently is formed on the sliding sheath. After the puncture needle is pulled out, the sliding sheath is pinched and pushed upwards to slip upwards along the liquid guide hose, the sliding opening formed on the sliding sheath can dodge the handle, and the puncture needle can be covered by the sliding sheath, thus the puncture needle is effectively prevented from pricking others by mistake, the phenomenon that medical staff is pricked accidentally by the puncture needle can be avoided, and cross infection of blood-borne diseases caused by the reason that medical staff and medical waste treatment persons are pricked accidentally by a needle head carrying blood-borne diseases can be eliminated.

Description

The anti-device of stabbing of disposable aspiration needle

[technical field]

This utility model relates to a kind of Dispoable medical delivery device, relates in particular to the anti-device of stabbing of a kind of disposable aspiration needle.

[background technology]

In transfusion, blood transfusion, hemodialysis, daily curative activity such as draw blood, donate blood, the medical worker must use the disposable aspiration needle of band liquid guiding tube, a syringe needle need puncture into infuses in the patient's blood vessel or draws blood, when patient's sufferer had bloodborne diseases, the medical worker will increase infected probability.The disposable aspiration needle of existing band liquid guiding tube has two kinds of structures, and first kind is monolever structure such as Fig. 1, is mainly used in transfusion, blood drawing aspect.Second kind be the dual-handle structure as shown in Figure 2, be mainly used in hemodialysis, donate blood.They comprise all that pin emits 1,puncture needle 2,handle 3,needle handle seat 4 and draw liquidflexible pipe 5,puncture needle 2 is fixed on the upper end ofneedle handle seat 4, draw liquidflexible pipe 5 and be fixed on the lower end ofneedle handle seat 4 hermetically,handle 3 is arranged on the side ofneedle handle seat 4, and pin emits 1 to be sleeved on the puncture needle 2.During use, the medical worker at first pulls out pin and emits 1, thenpuncture needle 2 is punctured in the patient's blood vessel infuse, blood transfusion, hemodialysis or donate blood, in this operating process,puncture needle 2 must contact with patients'blood, after finishing corresponding medical matters activity, must transfer topuncture needle 2, becausepuncture needle 2 has been infected by patients'blood,puncture needle 2 after this can not puncture the third party, otherwise will be carried out cross infection with patient by thorn the 3rd people.In the actual medical activity, whenpuncture needle 2 is extracted from patient's blood vessel, must emit 1 toentangle puncture needle 2 with pin, prevent thatpuncture needle 2 is exposed to outside, guaranteepuncture needle 2 not acupunctures other people.Emit in 1 the process adding a cover pin, especially when busy operation, the another that careless slightly punctureneedle 2 will be punctured to the nursing staff on hand, therefore, the medical worker who is engaged in above-mentioned work is very easy to suffer infringement, the especially nurse of the sick cross infection of unexpected blood sensing.The applicant is through conscientious test statistics, emits 1 o'clock adding trocar, and medical worker's accident is by the ratio to 60% of stinging～63%, at casualty department, and outpatient transfusion room, blood dialysis room, the ratio that medical worker's accident of section office such as ICU is stung is higher.For this reason, nobody is ready to be engaged in blood sexually transmitted disease (as hepatitis B, hepatitis C, syphilis, acquired immune deficiency syndrome (AIDS) etc.) patient's medical treatment and nursery work.At present, there is very big stress in the medical worker who is engaged in above-mentioned work in real work, go up all existential anxiety and fear at heart.On the other hand, also there is the hidden danger that infects other people in the processing to these blood sexually transmitted diseases (as hepatitis B, hepatitis C, syphilis, acquired immune deficiency syndrome (AIDS) etc.) used syringe needle of patient.How to protect medical worker's work safety, prevent that not infected when the medical worker is engaged in above-mentioned work is that medical affairs system wishes to solve and the technical barrier that do not have to solve for a long time.At present, best protective approach is to improve sense of self-protection, and strict rule of operation as long as rely on sacrifice speed, is guaranteed handling safety.Up to the present, also there is not thoroughly to eliminate the technical scheme of above-mentioned potential safety hazard.

[utility model content]

The purpose of this utility model provides the anti-device of stabbing of a kind of disposable aspiration needle; it has changed traditional needle guard mechanisms; can thoroughly eliminate puncture needle medical worker's accident mistake is stung phenomenon, thereby guarantee the blood sexually transmitted disease cross infection that medical worker and hospital refuse treatment people are not caused by the unexpected mistake thorn of blood sexually transmitted disease syringe needle.

The technical scheme that this utility model is taked is as follows:

The anti-device of stabbing of disposable aspiration needle, comprise that pin emits, puncture needle, handle, needle handle seat and draw the liquid flexible pipe, puncture needle is fixed on the upper end of needle handle seat, draw the liquid flexible pipe and be fixed on the lower end of needle handle seat hermetically, handle is arranged on the side of needle handle seat, pin emits and is sleeved on the puncture needle, it is characterized in that: be provided with the slip sheath on the liquid flexible pipe drawing, correct the lower end that props up the needle handle seat on the slip sheath, on the slip sheath, be provided with and be convenient to the slip opening that handle passes, the length of slip sheath is emitted with needle handle seat sum big 5～10 millimeters than pin, the length of slip opening is bigger 3～5 millimeters to the distance of handle lower end than the needle point of puncture needle, the endoporus of slip sheath with draw liquid flexible pipe interference fits, during pulling slip sheath, the slip sheath can move along drawing the liquid flexible pipe, and when not stressing, the slip sheath can not glide.

Further, for the monolever pin, on the slip sheath, be provided with a slip opening.

Further, for the dual-handle pin, on the slip sheath, be provided with two slip openings symmetrically.

Further, be provided with reinforcement in the lower end of slip sheath.

Owing to set up the slip sheath on the liquid flexible pipe drawing, on the slip sheath, be provided with the slip opening, the length of slip sheath is that pin emits and needle handle seat sum, the length of slip opening is bigger 3～5 millimeters to the distance of handle lower end than the needle point of puncture needle, the endoporus of slip sheath with draw liquid flexible pipe interference fits, during pulling slip sheath, the slip sheath can move along drawing the liquid flexible pipe, when not stressing, the slip sheath can not glide.After extracting puncture needle, upwards push away as long as pinch the slip sheath with hands, the slip sheath is promptly along drawing the slippage that makes progress of liquid flexible pipe, owing on the slip sheath, be provided with the slip opening, can dodge handle, when on when moving on to extreme position, the slip sheath has just covered puncture needle, 3～5 millimeters at the needle point of puncture needle is stretched out on the top of slip sheath, so just can prevent effectively that puncture needle from stinging other people by mistake, comprise medical worker or hospital refuse treatment people, can thoroughly eliminate puncture needle medical worker's accident mistake is stung phenomenon, can guarantee the blood sexually transmitted disease cross infection that medical worker and hospital refuse treatment people are not caused by the unexpected mistake thorn of blood sexually transmitted disease syringe needle.This utility model is simple in structure, and is safe and convenient to use.
