Description
Technical Field
The utility model relates to the technical field of manual blood drawing protective devices, in particular to a protective device for preventing puncture injury in A-line blood sampling.
Background
A-line blood sampling is one of blood sampling frequently used by medical care, the requirement on the attention of medical care is high, a needle is inserted into a device connected with an artery of a patient and then pulled out in the general blood sampling process, and in the process, due to the fact that the device connected with the patient moves, medical care is likely to prick the needle into the hand due to great instability during pulling out, cross infection is caused, and medical care work is affected. In order to solve the problems, the application provides a protection device for preventing the needle stick injury during the blood sampling of the A-line.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention provides a protection device for preventing needle stick injury in a-line blood sampling.
In order to solve the technical problem, the utility model provides a protection device for preventing needle stick injury in A-line blood sampling, which comprises a needle cylinder, wherein the needle cylinder comprises a thin-diameter section for sleeving a needle and a thick-diameter section for sleeving the needle; install a protection section of thick bamboo pad in the thin footpath section slidable, this protection section of thick bamboo pad center is dug there is the pinhole for running through of needle, the one end that the protection section of thick footpath section of filling up is provided with a reset spring, and this reset spring's end and the inner wall fixed connection of thin footpath section, reset spring provide protection section of thick bamboo pad and resume initial position parcel needle.
Preferably, the large-diameter section is one or more of PVC, PP and PE and has flexibility, so that the large-diameter section is connected with the needle tube; the small-diameter section is one of PP and PE.
Preferably, the protection section of thick bamboo pad is the latex material, and is preferred, is provided with the stereoplasm plastic tubing of stereotyping in the pinhole of protection section of thick bamboo pad for protection section of thick bamboo pad contact patient skin carries out the comfort level and promotes and can also carry out stretching out relatively of needle.
Preferably, the protective barrel pad is located at least partially outside the barrel.
Compared with the prior art, the utility model discloses a protection device that A-line blood sampling prevented that acupuncture from hindering adopts the mode that cylinder and protective barrel pad cup jointed, the cylinder adopts thick footpath section and thin footpath section, be convenient for be suitable for more needle tubing and not influence the shade that prevents the acupuncture to the needle, through the fixed of cylinder and needle tubing, when protective barrel pad pricks into in patient's skin or relevant utensil, because top layer skin's restriction, protective barrel pad gos deep into in the cylinder, make the needle spill, after the blood sampling finishes, the in-process that the needle was extracted, and simultaneously, protective barrel pad shade needle is released to reset spring's motive force, thereby prevent to prick and to doctorse and nurses, the security is better, in addition, device adaptation needle tubing model is abundant, and the practicality is higher.

Detailed Description
In order to facilitate understanding of the technical solutions of the present invention, the following detailed description is made with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-3, a protection device for preventing a needle stick injury in a-line blood sampling comprises a needle cylinder, wherein the needle cylinder comprises a small-diameter section 1 for sleeving a needle and a large-diameter section 2 for sleeving the needle cylinder; install a protection section of thick bamboo pad 5 in thin footpath section 1 slidable ground, this protection section of thick bamboo pad 5 center is dug there is pinhole 6 for running through of needle, the one end that protection section of thick footpath section 5 is close to thick footpath section 2 is provided with a reset spring 3, this reset spring 3's terminal and the inner wall fixed connection of thin footpath section 1, and reset spring 3 provides protection section of thick bamboo pad 5 and resumes initial position parcel needle.
Preferably, the large-diameter section 2 is one or more of PVC, PP and PE, and has flexibility, so that the large-diameter section 2 is connected with the needle tube; the small-diameter section 1 is one of PP and PE.
Preferably, protection section of thick bamboo pad 5 is the latex material, and is preferred, is provided with the stereoplasm plastic tubing of stereotyping in the pinhole 6 of protection section of thick bamboo pad 5 for protection section of thick bamboo pad 5 contacts patient's skin and carries out the comfort level and promote and can also carry out stretching out relatively of needle.
Preferably, the protective cylinder cushion 5 is located at least partially outside the cylinder.
The working principle is as follows: through the fixation of needle cylinder and needle tube, when protective cylinder pad 5 pricks into patient's skin or in the relevant utensil, because the restriction of top layer skin, protective cylinder pad 5 gos deep into the needle cylinder in, makes needle 4 spill, and after the blood sampling, the in-process that needle 4 was extracted, simultaneously, the driving force of reset spring 3 released protective cylinder pad 5 and covers the needle to prevent to prick and nurse medical care
The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is defined by the scope defined by the claims, and a plurality of modifications and decorations made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as the protection scope of the present invention.
