When the device is used for moving and taking liquid agents, the knob is rotated to a specified volume scale, the knob drives the gear, and therefore the rotary shaft and the rolled band are driven, the piston is lifted, negative pressure is generated in the pipe body, the liquid agents are sucked into the pipe through the needle head, the moving and taking process is achieved through the mechanical operation, the agent moving and taking errors are greatly reduced, and the quantitative moving and taking of the agents is more precise.
Description
Technical field
The utility model relates to medical apparatus technique field, is specifically related to a kind of liquid preparation quantitative taking out device.
Background technology
At present, medicine bottle for carrying liquid medicament is generally all comprised of bottle and bottle cap matching used with it, the personnel such as patient or doctor mostly are while taking medicine and directly open bottle cap and topple over, and be very easy to cause liquid to spill, and take the bad control of amount of liquid while toppling over.Along with the research and development of medical product are goed deep into gradually, the drug effect of medical product is also become better and better, and therefore, now increasing medical product is when patient takes, all dose is had to strict control, dose is excessive, can bring adverse effect to patient, and dose is too small, can not give full play to drug effect again, out of reach good result for the treatment of, especially a liquid preparation, accurate quantitative analysis is taken the larger difficulty of existence.Although also there is the traversing taking device of some liquid soups at present, such as pipet, quantifying spoon etc., but these devices are when pipetting medicine, although it is more accurate directly to topple over before comparing, but manual operation is still occupied an leading position, for example observe scale mark, extruding rubber plug etc., inevitably bring larger personal error.How to reduce the error of manual operation, liquid preparation quantitative fetching is more accurately problem demanding prompt solution in current industry as far as possible.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the existing deficiency of above prior art, and a kind of liquid preparation quantitative taking out device has been proposed, this device is provided with rotating shaft, winding, piston, syringe needle, gear and knob, while pipetting liquid preparation, rotation knob is to designated volume scale, knob driven gear, drive rotating shaft, drive winding, winding drives piston, produces negative pressure in body, liquid preparation is inhaled in pipe by syringe needle, the process of pipetting is power operation, has greatly reduced the error that medicament pipettes, and medicament is quantitatively pipetted more accurate.
The utility model scheme is achieved by the following technical measures:
A kind of liquid preparation quantitative taking out device, this device comprises body, syringe needle, piston, piston is located in body, its feature is that the interior rear end of the body of this device is provided with rotating shaft, rotating shaft connects piston by winding, tube wall rear end is provided with groove, in groove, be provided with knob, calibrated disc, gear, screens catch, knob is fixedly connected with gear, gear another side is fixedly connected with rotating shaft, screens catch is located at gear bottom and is fixedly connected with catch anchor shaft, and catch anchor shaft is fixed on groove inner tubal wall, and calibrated disc is located on the tube wall in groove.
Above-described needle tip inwall is provided with check sheet.
Above-described screens catch extends into the wheel backlash of gear.
On the rear end sidewall of above-described body, be also provided with an air linked hole.
The beneficial effects of the utility model are: when this device is used, according to required bolus volume, rotation knob, knob driven gear, gear driven rotating shaft is rotated, winding is rolled in rotating shaft, winding jigger lifting piston, because body rear end sidewall is provided with air linked hole, therefore body inner carrier lower end cavity produces negative pressure, the check sheet that liquid preparation breaks through syringe needle is inhaled in pipe, when knob rotates to assigned scale, the wheel backlash that screens catch extends into gear forms braking, gear, rotating shaft, winding, piston deceleration, it is normal that body inner carrier lower end cavity air pressure recovers, check sheet on needle tip inwall recovers level, stop medicament in body to be oozed out by syringe needle, pipetting medicament completes, when medicament is used, anti-phase rotation knob, can medicament in body be extruded by syringe needle by piston.This device quantitatively pipettes the process of medicament, mostly is mechanical step, has greatly reduced the error that medicament pipettes, and medicament is quantitatively pipetted more accurate.The utility model is simple in structure in addition, and manufacturing cost and use cost is lower, has higher application value.
