Treatment device for medical injector and use method of treatment device

Abstract

The invention discloses a treatment device for a medical injector and a use method of the treatment device, and belongs to the field of medical injections. The treatment device can integrate a piston assembly, a medicine bottle and a needle head, when the piston assembly moves downwards to conduct injection operation, liquid medicine is injected into the body of a patient through extrusion of a film on the medicine bottle, so that it is guaranteed that the liquid medicine does not make contact with the external environment in the whole process of injection operation, and pollution is avoided; meanwhile, when the injection operation is finished, through ordered conversion of space leakproofness and non-leakproofness in the piston assembly, the film is driven to expand outwards, the medicine bottle falls off from the position where the medicine bottle is clamped by the film currently, the clamping relation cannot be recovered, and the needle head is almost impossible to be aligned to the positions of an upper cover and a lower cover of the medicine bottle for the second time, so that the situation that the injector is used for the second time is effectively avoided; and in the process of injection, mutual matching between bandage sending out and bandage receiving is adopted to prevent secondary use.

Description

technical field [0001] The invention relates to the field of medical injectors, more specifically, to a processor for medical injectors and a method for using the same. Background technique [0002] The types of syringes include medical syringes and experimental syringes. Syringes are mainly used in the fields of biology, medicine and chemistry. [0003] A medical syringe refers to a medical device used by medical staff to inject patients from the skin. Its function is to directly inject the drug into the human body through injection to eliminate the virus in the blood, so as to achieve a more efficient treatment effect and enable patients to recover their health as soon as possible. [0004] Most of the processors for medical syringes currently on the market place the injection device and the drug to be injected separately. When a patient needs injection treatment, the medical staff will take out the syringe and the drug to be injected at the same time. The use process is ...

Problems solved by technology

[0007] Aiming at the problems existing in the prior art, the object of the present invention is to provide a processor for medical syringes and its usage method, which can integrate the piston assembly, the medicine bottle and the needle, and carry out the process when the piston assembly moves downward. At the same time as the injection operation, the liquid medicine is injected into the patient's body through the extrusion of the film to the medicine bottle, which ensures that the medicine liquid does not come into contact with the external environment during the injection process and avoids pollution. At the same time, when the injection operation is over, At this time, through the orderly conversion of the airtightness and non-airtightness of the space in the piston assembly, the film is driven to expand outward, and the medicine bottle falls from the current position where the film is clamped, and this clamping relationship cannot be restored. It is almost impossible to re-align the position of the upper cap and the lower cap of the vial, which effectively avoids the situation that the syringe is used twice, and during the injection process, there is a gap between the strap sending and the strap receiving. The mutual cooperation of the fixed block is firmly fixed on the patient's arm, avoiding the occurrence of the needle slipping due to the patient's own movement, and reducing the difficulty of operation for the operator
