Pricking preventing infusion needle special for puncture type connecting piece

Abstract

The invention discloses a pricking preventing infusion needle special for a puncture type connecting piece. The pricking preventing infusion needle comprises a needle tube, a needle seat and an infusion catheter connected with the rear end of the needle seat and is characterized in that the needle tube and a sheath capable of containing the puncture type connecting piece are fixed to the needle seat. According to the pricking preventing infusion needle special for the puncture type connecting piece, the structure is simple and reasonable, the process is simple, manufacturing is easy, and a columnar handheld handle, a fixed part and a supporting part are arranged; the sheath which is provided with a side opening short needle, prevents pricking in the whole operation process and has expanding performance is adopted, the infusion needle can be connected with different positions of the puncture end face of the puncture type connecting piece and connected with the puncture type connecting piece on a Y-shaped remaining needle, and nosocomial infection and other matter entering the blood vessels of the human body can be reduced. The problem that no safe special infusion needle exists in existing clinical treatment can be solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a needle-puncture-proof puncture-type connector special infusion needle, which is specially used for infusion and blood transfusion of products equipped with puncture-type connectors. Background technique [0002] After long-term observation and experiments in the clinic, we found that there are many defects in the infusion devices connected with indwelling indwelling devices such as indwelling needles and central venous catheters in the current clinical infusion. However, the existing disclosed technical solutions are difficult to be practically applied and promoted due to structural or process problems, product production difficulties and operational performance defects. Their defects are: [0003] 1. After the existing infusion needle is docked with the puncture connector of the indwelling device, there is no protection or fixing device, and it cannot be connected in the air, an...

AI Technical Summary

Problems solved by technology

[0002] After long-term observation and experiments in the clinic, we found that there are many defects in the infusion devices connected with indwelling devices such as indwelling needles and central venous catheters in the current clinical infusion. However, the existing disclosed technical solutions are difficult to be practically applied and promoted due to structural or process problems, product production difficulties and operational performance defects. Their defects are:

[0003] 1. After the existing infusion needle is docked with the puncture connector of the indwelling device, there is no protection or fixing device, and it cannot be connected in the air, and can only be fixed on the human limb

[0004] 2. After the existing infusion needle is docked with the puncture-type connector of the indwelling device, the support points of the two on the human body are in different planes, and the use of adhesive tape cannot firmly fix the infusion needle seat and the puncture-type connector, making the root of the infusion needle easy to Under the breaking force, there is a phenomenon of broken needles

[0005] 3. Tape fixation, one is that patients need to accept more tapes, and it may also increase the chance of allergies, and the other is that the operation is more troublesome

[0006] 4. The existing unsafe and safe infusion needles are not reliable, and accidental needle stick injuries cannot be completely avoided during operation

[0007] 5. The existing safety special infusion needle technology cannot puncture the different parts of the infusion end face of the puncture connector

[0008] 6. The needle tube of the traditional infusion needle is too long compared to the puncture-type connector, which is prone to broken needles and the needle tip hits the side wall of the infusion set during the connection process, causing the needle tip to barb and damage the seal of the puncture-type connector when pulled out

[0009] 7. The existing safety infusion needle cannot be connected with the piercing connector on the Y-shaped indwelling needle

[0010] 8. We found in the clinical investigation that the needle point of the existing infusion needle is a slanted needle, and its disadvantages when it is used for indwelling needles to connect infusions are: when puncturing the piercing connector, the puncture port is a line, and the needle tube is opened. The opening is located on the slope of the needle tip, so that various substances on the puncture line, including microorganisms, various particles, and various organic or inorganic substances, can be easily brought into the infusion set system, which may cause nosocomial infection and other hazards
