Automatic medicine tube replacing and taking device for needleless injector

Abstract

The invention provides an automatic medicine tube replacing and taking device for a needleless injector. The automatic medicine tube replacing and taking device comprises a mechanical arm, an injection pressure control module and an automatic medicine tube replacing and taking module. An electric needleless injector is arranged on the injection pressure control module; the mechanical arm is used in cooperation with the injection pressure control module and the automatic medicine tube replacing and taking module. The needle-free injection technology is adopted, the pain of people fear of needles is greatly reduced, the workload of nurses is greatly reduced, meanwhile, the transmission of blood infectious diseases is blocked by replacing the medicine tube, the occupational exposure risk of medical staff is avoided, and contribution is made to epidemic situation prevention and control.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for automatically changing medicine tubes for needle-free syringes. Background technique [0002] Needle-free injection technology is an injection method without a traditional capillary needle. It does not need to be pierced into the body through a needle, but a certain pressure is generated by the needle-free injection pusher through a mechanically stable annular compression spring system. Push the liquid medicine, the liquid medicine is sprayed through a small hole with a diameter of about 0.12mm, the initial speed of the spray is about 200m / s, and the liquid medicine is sprayed in a diffuse state, so that the liquid medicine penetrates the skin and injects into the subcutaneous tissue of the patient. Therefore, the pain and fear of needle sticks will be reduced to a certain extent. Spring ejection is controlled by triggering a push switch. First, pressurize ...

AI Technical Summary

Problems solved by technology

[0004] One: When the epidemic outbreak is concentrated, the workload of medical staff is heavy, and the traditional large-scale subcutaneous injection of vaccines will inevitably occupy a large amount of medical resources

[0005] Two: In the patent - automatic injection equipment for pig vaccines, it is mentioned that the injection method is needle injection. If a needle is used to achieve large-scale injection of vaccines, it is technically difficult and needle injection It will bring a lot of discomfort to people who are afraid of needles

[0006] Three: Most of the existing electric needle-free injectors are manually operated. If the outbreak is concentrated, it will inevitably bring a lot of burden to the medical staff. If a fully automatic device is used to replace the medical staff for injection, the workload of the medical staff can be greatly reduced. Epidemic prevention and control saves more medical resources and makes great contributions to epidemic prevention and control

[0007] Four: The existing electric needle-free injector lacks the link of removing the air bubbles in the needle tube before injection, and the day when the air bubbles are injected into the human body, it may cause redness, swelling and pain, and in severe cases, it may damage the human blood vessel and nerve tissue.

[0008] Five: Exchanging the drug tube for the existing electric needle-free syringe can only be carried out by manpower, and it is impossible to automatically exchange the drug tube. If the drug tube is not replaced every time the injection is made, it will easily lead to the spread of blood-related infectious diseases

[0010] Patent 1: CN107441594A - a fully automatic painless injection device. This patent uses a needle injection, using a bracket, an electromagnet, a stepping motor, and a controller to move the needle and quickly pierce the needle into the human skin, but For injection with a needle, without other auxiliary conditions, it is difficult to confirm the specific injection site through the existing machine vision technology, and it is also difficult to control the specific injection depth of the needle. However, the needle-free injection technology can avoid the above problems. The circular area drawn by the nurse in advance is enough, because there is no needle, so there is no need to consider the issue of needle injection depth
