Description

Scalp needle structure for preventing puncture

Technical Field

The utility model belongs to the technical field of medical instrument, a prevent scalp acupuncture structure of stabbing is related to.

Background

Venous transfusion is a common main way for treating diseases, a scalp needle sheath of an existing transfusion device is a straight-tube-shaped needle cap, the needle cap is pulled out during transfusion to expose a needle head for venous transfusion, the needle head does not have a protection device when the needle head is pulled out after transfusion is finished, nursing staff or patients can be injured by mistake often to cause needle stick injuries, particularly, when the needle cap is inserted back to the needle head by the nursing staff, if the needle head is not aligned, the needle head is easy to be inserted and deviated to stab the hand of the nursing staff, and meanwhile, the hidden danger of disease infection such as HBV, HCV and HIV can be brought. The existing scalp needle has potential safety hazards, and a protective scalp needle capable of reducing the potential safety hazards is urgently needed in society.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems in the prior art, and provides a puncture-proof scalp acupuncture structure which has reasonable and simple structure and convenient use and can prevent the scalp acupuncture from puncturing the human body and causing infection after the scalp acupuncture is used.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a prevent scalp acupuncture structure of stabbing, includes syringe needle, needle handle, connecting pipe, lag and needle cap, its characterized in that, and the one end and the needle handle of syringe needle are connected, and the outer fixed cover of needle handle is equipped with the installation shell, and installation shell tail end is connected with the connecting pipe, and the installation shell is equipped with the external screw thread outward, and the lag inner wall is equipped with the internal thread, and the lag is established in the installation shell outside and is connected through external screw thread and interior screw-thread fit, and needle cap cover is on the syringe needle and the needle cap inserts in the lag.

Furthermore, the inner side of the front end of the protective sleeve is provided with a convex guide step, and when the needle cap is inserted, the guide step is attached to the needle cap.

Further, the length of the protective sleeve is greater than the length of the needle.

Furthermore, the material of the protective sleeve is transparent plastic material.

Furthermore, the outer side of the tail end of the mounting shell is connected with 1-2 needle wings.

Furthermore, a circle of annular anti-skidding belt is arranged on the outer side of the front end of the protecting sleeve.

During infusion, the needle wing is pinched by one hand, the anti-slip belt of the protective sleeve is pinched by the other hand, the protective sleeve is rotated, the protective sleeve is retreated backwards, the needle cap and the needle head are exposed, and the needle cap is pulled out, so that the infusion can be carried out. After the infusion, the protective sleeve is turned back to the original position, and the needle cap is inserted into the protective sleeve. Because the protective sleeve is in sliding fit with the needle cap, the needle cap can be accurately sleeved on the needle head, and the needle head pricking caused by the inclined insertion of the needle cap can be avoided.

Compared with the prior art, the scalp acupuncture structure for preventing puncture has the following advantages:

1. after infusion, the needle can retract into the protective sleeve, and the needle can be prevented from stabbing when the needle is sleeved with the needle cap;

2. stable in structure, easy operation is difficult to damage.

Drawings

Fig. 1 is a cross-sectional view of the present puncture resistant scalp needle construction.

Fig. 2 is a using state diagram of the puncture-proof scalp needle structure.

In the figure, 1, a needle head; 2. a needle handle; 3. a connecting pipe; 4. a protective sleeve; 41. an internal thread; 42. a guide step; 43. an anti-slip band; 5. a needle cap; 6. installing a shell; 61. an external thread; 62. and (4) needle wings.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, this scalp acupuncture structure of preventing stabbing, including syringe needle 1, needle handle 2, connecting pipe 3, lag 4 and needle cap 5, the one end and the needle handle 2 of syringe needle 1 are connected, 2 outer fixed covers of needle handle are equipped with

installation shell

6, 6 tail ends of installation shell are connected with connecting pipe 3, installation shell 6 is equipped with external screw thread 61 outward, lag 4 inner wall is equipped with internal thread 41, lag 4 is established in the 6 outsides of installation shell and is connected with internal thread 41 through external screw thread 61 cooperation, needle cap 5 overlaps on syringe needle 1 and needle cap 5 inserts in lag 4.

The inner side of the front end of the protective sleeve 4 is provided with a convex guiding step 42, and when the needle cap 5 is inserted, the guiding step 42 is abutted with the needle cap 5. The material of lag 4 is transparent plastic material, and the length of lag 4 is greater than the length of syringe needle 1, lag 4 front end outside has round annular antiskid area 43.

The outer side of the tail end of the mounting shell 6 is connected with 1-2 needle wings 62, when in transfusion, one hand holds the needle wings 62, the other hand holds the anti-skid band 43 of the protective sleeve 4, the protective sleeve 4 is rotated to enable the protective sleeve 4 to retreat backwards, the needle cap 5 and the needle head 1 are exposed, and the needle cap 5 is pulled out to carry out transfusion. After the infusion, the shield 4 is turned back to the original position and the needle cap 5 is inserted into the shield 4. Because the protective sleeve 4 is in sliding fit with the needle cap 5, the needle cap 5 can be accurately sleeved on the needle head 1, and the needle head 1 can be prevented from being pricked due to the fact that the needle cap 5 is inserted to be inclined.

The specific embodiments described herein are merely illustrative of the spirit of the invention.
