Description
Technical Field
The utility model belongs to the technical field of the medical instrument technique and specifically relates to a venous transfusion felting needle.
Background
When a patient has a fever and a cold, or some other diseases, a human body is generally infused with medicine by adopting an intravenous infusion mode, a needle cap is usually removed and discarded when a scalp needle clinically used at present is used, and the same treatment is carried out after the infusion is finished, however, the operation mode not only causes the dropping of medical liquid, but also can cause the puncture of medical staff by the needle head, and particularly if the patient suffers from infectious diseases, the safety of the medical staff is easy to be damaged;
in conclusion, the existing scalp acupuncture has the following problems:
1. the needle cap and the scalp needle are designed in a separated mode, so that medical waste cannot be collected simultaneously;
2. after the use, the medical liquid is easy to drip and splash because the needle head is exposed;
3. after the scalp needle is used, the needle head is exposed outside, which is easy to cause harm to the safety of medical care personnel.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a venous transfusion felting needle, it can effectively solve the problem that exists among the prior art. The specific scheme is as follows: an intravenous infusion puncture needle comprises a needle sleeve, a needle cap, a needle base, a needle head and a needle tube; the needle sleeve is characterized in that a plurality of limiting grooves are formed in the top end of the needle sleeve in the circumferential direction, a plurality of limiting protrusions I are arranged on the inner end face of the needle cap in the circumferential direction, the top end of the needle sleeve is connected with the needle cap, each limiting groove is in sliding connection with one limiting protrusion I, an elastic layer is arranged at the top end of the needle cap, and a needle passing hole is formed in the middle of the elastic layer; the needle head is communicated with the top end of the needle seat, the needle tube is sleeved at the outer end of the bottom end of the needle seat, and a needle wing is arranged on the outer side of the body part of the needle seat; the needle sleeve is provided with a first sliding groove and a second sliding groove at two ends along the length direction respectively, the first sliding groove and the second sliding groove are communicated through a third sliding groove, and the width of the first sliding groove and the width of the second sliding groove are both larger than the width of the third sliding groove; when the needle is not used, the needle head, the needle seat and the needle tube are inserted in the needle sleeve, and the needle wing is arranged in the first sliding groove; the diameter of the needle tube is smaller than that of the needle seat, and a limiting ring is arranged on the inner side of the needle sleeve below the needle seat.
Preferably, the elastic layer is tpe material or medical silica gel.
Preferably, the limiting ring is made of elastic material and is glued with the needle sleeve.
Preferably, the outer side of the upper portion of the needle seat is provided with a second limiting protrusion, the inner side of the upper portion of the needle sleeve is provided with an L-shaped groove, and the second limiting protrusion can be fixed through the L-shaped groove.
The utility model has the advantages that: the intravenous infusion puncture needle provided by the utility model has the advantages that the needle cap is connected with the needle sleeve in a sliding way, the needle head can be extended without removing the needle cap, and the uniform arrangement of medical waste is convenient; when the needle is used, the needle wing moves from the first sliding groove into the second sliding groove, rotates for a certain angle and is limited by the third sliding groove, the second limiting protrusion on the needle tube is fixed through the L-shaped groove, the needle moving port on the needle cap tightens and clamps the needle head, and the needle sleeve and the needle seat are prevented from being misplaced by the mechanisms together; after the needle cap is used, the puncture needle returns to the needle sleeve, the needle seat returns to the position of the limiting ring at the tail of the needle sleeve, the limiting ring and the needle seat are clamped tightly to prevent the needle head from slipping out, and meanwhile, the elastic layer on one side of the needle cap is tightened up through the needle outlet, so that the needle head cannot be exposed outside to puncture medical care personnel.
