Manufacturing method of infusion indwelling part connector for reducing hospital infection

Abstract

The invention discloses a manufacturing method of an infusion indwelling part connector for reducing hospital infection.The manufacturing method is characterized by including the following steps that firstly, a steel needle is manufactured or purchased, wherein a conical needle tip is produced or purchased, the steel needle located on the rear side wall of the rear edge of the conical needle tip is holed, and the diameter of the steel needle ranges from 0.3 mm to 0.9 mm; secondly, the steel needle and a needle base are bonded or riveted or welded; thirdly, or, the steel needle and other parts are further bonded or heat-sealed or welded or assembled, packaged, sterilized and checked out, and then the infusion indwelling part connector is obtained.According to the manufacturing method of the infusion indwelling part connector, the structure is simple and reasonable, the probability of occurrence of hospital infection, infusion reaction and allergy caused when attachments on the infusion end face of an infusion indwelling part enter the blood vessel of the human body can be reduced, connecting and fixing are convenient, and thus the use safety of an existing infusion instrument can be improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a manufacturing method for a connector of an indwelling infusion device that can reduce nosocomial infections. Background technique [0002] After long-term clinical observation and experiments, we found that current manufacturers have cognitive blind spots in the production and use of infusion indwelling devices by clinical medical staff, resulting in infusion indwelling devices connected with indwelling needles and central venous catheters in the current infusion. The connectors used (infusion needle / device and injection needle / device) have defects in the design and use process, and their blind spots and product design defects are as follows: [0003] 1. The indwelling needle and central venous catheter are to be left in the patient's body for many days, and need to be connected to the indwelling infusion connector (infusion set or / and injection set) once or several times a day. ...

AI Technical Summary

Problems solved by technology

Due to the existence of the above-mentioned problems, the needleless connection is the most unsafe among the currently used infusion connection devices, and the steel needle connection is a relatively safe connection device. The setting is at the front end of the steel needle. When the steel needle punctures the infusion end face of the infusion indwelling part (puncture indwelling part), a linear incision will be made on the infusion end face. The steel needle will stretch the sealing material into the infusion system through this linear incision. When the forward opening of the steel needle passes through the linear incision, it will bring in the edge of the linear incision and various attachment spatulas on the nearby end surface of the infusion solution, which may cause infection and other diseases

Third: The existing steel needle design is mainly for intravenous infusion and intramuscular injection. It is longer and thicker, which relatively increases the exposed area during use and increases the chance of contamination.

Fourth: At present, all connectors connected to indwelling infusion parts will be directly exposed to the use environment in all directions, which will also increase the risk of use

[0004] 2. After the existing infusion needle is docked with the piercing connector in the infusion 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

[0005] 3. After the existing infusion needle is docked with the puncture-type connector in the infusion 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 infusion The root of the needle is easily subjected to breaking force, resulting in broken needles

[0006] 4. 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

[0007] 5. The existing unsafe and safe infusion needles are unreliable, and accidental needle stick injuries cannot be completely avoided during operation

[0008] 6. The existing safety special infusion needle technology cannot puncture the different parts of the infusion end face of the puncture connector

[0009] 7. The traditional infusion needle is too long compared to the puncture-type connector, and it is easy to break the needle and the needle tip hits the side wall of the infusion set during the connection process to make the needle tip barb, and damage the seal of the puncture-type connector when pulled out

[0010] 8. The existing safety infusion needle cannot be connected with the piercing connector on the Y-shaped indwelling needle
