Connection type infusion needle

Abstract

The invention discloses a connection type infusion needle which comprises a steel needle body, a needle base and an infusion catheter behind the needle base. The connection type infusion needle is characterized in that the needle base is columnar. The connection type infusion needle special for a puncture type connection piece is simple and reasonable in structure, can be manufactured through an existing technology, is provided with the columnar needle base, can be used as both a support and a handheld part, and can be directly connected in a suspension mode after connection, stability between the connection type infusion needle and the puncture connection type connection piece can be kept, a conventional steel needle protection cap or an anti-needle-puncture protective sheath can be used in cooperation, multi-portion puncture connection is achieved, the puncture connection type connection piece and the connection type infusion needle can be fixed through one piece of adhesive tape, infection in a hospital is reduced, it is avoided that other substances enter human body blood vessels, and the problem that no special infusion needles exist in existing clinical use is solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a connected infusion needle, which is specially used for the connection and transfusion of products equipped with piercing connectors. Background technique [0002] Through long-term observation and experiment, we found that in the current clinical infusion, the indwelling devices for infusion such as indwelling needles and central venous catheters are connected with infusion devices, so far there is no ideal special device that can be actually produced in batches and can be used in practice. However, the existing disclosed technical solutions are difficult to be practically applied and popularized due to structural or process problems, product production difficulties and operational performance defects. The defects of existing products and technologies that we have found are: [0003] 1. After the existing infusion needle is docked with the puncture connector of the indwelling de...

AI Technical Summary

Problems solved by technology

[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 when the two are fixed on the human body are on 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 Susceptible to breaking force, resulting in folded stitches

[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 unreliable, 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 steel needle of the traditional infusion needle is too long compared to the puncture-type connector, which is prone to needle folding 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
