Technical Field
The application relates to an immunity medical device, its concretely relates to bacterin ampoule device of getting it filled safely.
Background
Vaccination is a technique of vaccinating a vaccine preparation into a human or animal body, so that the recipient has immunity against a specific pathogen or a pathogen similar to the vaccine, and the foreign body is identified by the immune system, and antibodies are screened and produced to generate antibodies against the pathogen or the pathogen, so that the injected person has strong resistance against the disease.
In current medical practice, vaccines are generally placed in ampoules, which are opened by medical personnel and then the vaccine solution is withdrawn for injection.
The subject of vaccination is typically a child, and the timing of vaccination is typically batch vaccination. In the prior art, an operator takes out an ampoule bottle firstly, then uses a small grinding wheel to carve nicks on the bottleneck, and then uses a metal device such as a hemostatic forceps to break the bottleneck, namely, opens the ampoule bottle, and can draw medicine.
The disadvantages of such a procedure are: (1) the grinding wheel, the hemostatic forceps and the injector are taken and placed back and forth by two hands of an operator, the action is complicated, and the labor intensity is high during centralized inoculation; (2) the grinding wheel cannot be fully ground into the bottleneck, and certain skill is required for breaking the bottleneck; (3) during centralized inoculation, the actions are repeated for a long time, so that the wrists of medical staff are tired, if the bottleneck is broken and the force is too small or too large, the ampoule glass material bursts, large glass debris is mixed into the vaccine and is injected into the sick children, and the debris can not be metabolized by the human body, so that health hidden troubles can be caused.
Disclosure of Invention
Technical problem to be solved by the present application
In view of the above situation, the technical problem that this application mainly aims to solve is: (1) the operation steps required for opening the ampoule are reduced, and the ampoule opening process is simplified; (2) the generation of broken glass slag is reduced, and the safety of immunization is improved.
(II) technical scheme of the application
In order to solve the technical problem, the application provides the following technical scheme:
a safe vaccine ampoule taking device comprises a fixedly arranged machine shell and an ampoule bearing box fixed on the machine shell, wherein the ampoule bearing box can contain an ampoule and push the ampoule along the height direction of the ampoule, a screw rod is arranged in the ampoule bearing box and supported by a supporting threaded sleeve positioned on the machine shell, and an ampoule support is arranged at the free end of the screw rod;
the screw rod is also sleeved with a return spring;
the screw is also sleeved with a small gear sleeve axially limited by a bearing, the internal thread of the small gear sleeve is in threaded fit with the screw, the external part is a tooth surface, and the large gear shaft can be driven to rotate by the large gear meshed with the small gear sleeve when the small gear sleeve rotates;
the large gear shaft is provided with a pendulum bob, and the transmission ratio of the large gear to the small gear sleeve to the screw rod satisfies the following conditions: when the ampoule moves to the same depth position as the pendulum, the pendulum swings right to hit the ampoule neck.
Further, the bull gear is a partial gear.
Furthermore, the position corresponding to the ampoule bottle neck in the ampoule bearing box is provided with a grinding wheel, and the grinding wheel cuts the ampoule bottle neck in the process that the ampoule is pressed into the ampoule bearing box.
Furthermore, the grinding wheel has a plurality ofly, sets up respectively in ampoule both sides.
Furthermore, the shaft of the grinding wheel is arranged in a long hole on the mounting cover, and the grinding wheel shaft is tensioned by an elastic element, so that the grinding wheel can always contact the bottleneck of the ampoule.
Further, the ampoule bearing box is obliquely arranged towards the large gear shaft.
Furthermore, the ampoule bearing box and the vertical direction form an included angle of 45 degrees.
Further, the tread proportion of the bull gear is 270 degrees.
(III) advantageous effects
The beneficial effect of this application is: (1) the user can finish the action of opening the ampoule by one hand, and the situation that the glass of the ampoule bottle bursts due to nonuniform force after a large number of ampoules are opened is avoided, so that the slag dissolving risk is increased; (2) the inclined opening angle makes the generated slag fly out of the bottle as much as possible, thereby improving the safety of injection.

the
In the above device, the ampoule is pressed into the ampoule bearing box in a manner similar to the way that the bullet is pressed into the cartridge clip (the ampoule is successively in the A, B, C position in the attached drawing 1), and simultaneously, the gear mechanism is driven to swing the pendulum to impact the ampoule bottle neck. By the operation method, all actions of opening the ampoule can be finished by one hand. And because the ampoule is light in weight, all gears and screws can be made of plastic materials and the like which are easy to manufacture.
After the ampoule is opened, the whole device is reset to the original position by the reset spring.
Note that the pendulum above does not need to rotate through a complete circle, so there are:
