Description
Technical Field
The utility model relates to the field of medical equipment, a automatic come and go suction formula dispensing device is provided.
Background
The dispensing in the medical treatment refers to transferring a drug solution or a drug powder into a liquid bag for intravenous infusion, and conventional dispensing methods are generally performed using a syringe and a dispensing apparatus having a complicated operation. The applicant has disclosed a pedal-controlled reciprocating suction type dispensing device (patent No. 201720519380.9) which is controlled by a pedal switch to inject and suck back liquid into a medicine bottle, so as to prevent hands from directly contacting a main machine and being polluted, but the operation of the device still requires close cooperation of hands and feet of a nurse, and once the device is operated by mistake (if the injected liquid is excessive and the bottle is easily exploded, the suck-back is not thorough, so that the medicine residue is wasted), the error of the dispensing process is easily caused. If can further simplify the manual operation step, liberation nurse's both hands are both feet, reduce the probability of nurse's hand contact medicine, improve dispensing efficiency, will alleviate the heavy work of nurse greatly.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to further solve the complicated scheduling problem of operation that exists among the current dispensing technique, provide an automatic come and go suction formula dispensing device.
The utility model discloses the technical scheme who takes does: the device consists of a host machine, a switch, a dispensing pipeline and a medicine bottle fixing device, wherein the host machine of the device improves a manual double-foot-operated control host machine pump head forward and reverse wriggling program in a foot-operated control back-and-forth suction type dispensing device (patent number: 201720519380.9) disclosed by the applicant into the automatic completion of the host machine, after a key is started, the host machine pump head wriggles forward firstly to inject liquid into the medicine bottle quantitatively, after medicine powder is dissolved, the pump head wriggles reversely automatically to suck back the medicine liquid, and the whole dispensing process is automatically completed by the control of a preset program of the host machine. In order to avoid bottle explosion and reduce drug residue in the dispensing process, the amount of liquid injected into the medicine bottle by the positive peristalsis of the main machine pump head in the preset program needs to be less than the volume of the medicine bottle, the time for sucking back the medicine liquid by the reverse peristalsis of the pump head needs to be slightly longer than the time for injecting the medicine liquid into the medicine bottle by the positive peristalsis of the previous pump head, so as to ensure the complete suck-back of the medicine liquid, and meanwhile, because a small amount of air in the medicine bottle is sucked back more after the medicine liquid is sucked back, the medicine liquid at the needle hole is leaked and reduced instantly after the medicine. The amount of liquid injected into the medicine bottle in the preset control program of the host computer is adjustable according to the size (volume) of the medicine bottle. The switch controls the working state of the host machine and is started by one key, and the key can be pedal, hand-pressed or remote-controlled. The device is formed by a puncture needle and a peristaltic tube along the existing dispensing pipeline, and mainly provides a channel for transferring liquid medicine. The medicine bottle fixing device is composed of a medicine bottle clamping groove and a medicine bottle support and used for replacing a handheld fixed medicine bottle. During the use, earlier put into the host computer pump head with the peristaltic tube of the pipeline of dispensing in, puncture needle one end puncture of the pipeline of will dispensing again and go into in the liquid bottle, the other end pierces in the medicine bottle, go into the medicine bottle draw-in groove with the medicine bottle card in succession, the liquid amount that needs to pour into in the medicine bottle is set up according to the medicine bottle size in host computer panel department, start switch at last, according to predetermineeing the program host computer pump head and inject liquid in the medicine bottle forward wriggling earlier, treat that powder dissolves the automatic reverse wriggling of back pump head and inhale the liquid medicine in the medicine bottle to the liquid bottle and accomplish.
The utility model discloses relative prior art has following beneficial effect: this device is simplified and is come and go the suction operation step of dispensing, liberates nurse's both hands both feet, only needs a key starting switch, and the overall process of dispensing is predetermine program control by the host computer and is accomplished by oneself, avoids the artifical error of process of dispensing, improves dispensing efficiency, alleviates nurse's work.
The invention is further described below with reference to the accompanying drawings:
