Abstract
The utility model relates to a transfusion dropper air exhausting device comprising a rubber needle guard. The needle guard is arranged at an air outlet on the upper side of a dropper and is capable of sealing the dropper, a thrusting needle capable of puncturing the needle guard to exhaust air in the dropper is arranged in the rubber guard, a vent hole is arranged at the lower end of the thrusting needle, a air outlet hole is arranged at the upper end of the thrusting needle, an air channel for communicating the vent hole and the air outlet hole is arranged between the vent hole and the air outlet hole, an elastic sleeve is sleeved at the upper end of the thrusting needle, a dust-proof air hole capable of preventing dust from entering and inhaling air is arranged on the upper portion of the elastic sleeve, and an air strainer is arranged on the dust-proof air hole. With the transfusion dropper air exhausting device, unnecessary air in the dropper can be exhausted, the rubber guard is arranged to seal, sealability is good, security is high, the thrusting needle is utilized to puncture the needle guard to exhaust air and operation is convenient.
Description
[technical field]
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of transfusion drip tube exhaust apparatus.
[background technology]
Transfusion drip tube is a kind of important medical device, and liquid splashes into dropper, then flow to human body by dropper, while sneaking into too many air in dropper, gets rid of inconvenience, easily enters human body, brings potential safety hazard, and the effect of exhaust apparatus is to outside by the Bas Discharged in dropper.
The exhaust apparatus of the dropper that current medical institutions are used includes simple exhaustor and switch.In pressurization quick infusion process, in dropper, be easier to sneak into large quantity of air, general exhaust apparatus, switch sealing property is not strong, and medicine is easy to leak outside from here, causes medicinal liquid to be wasted in a large number, even has potential safety hazard.
[utility model content]
This utility model object is overcome deficiency of the prior art and a kind of favorable sealing property, safe and reliable dropper exhaust apparatus are provided.
In order to solve the technical problem of above-mentioned existence, transfusion drip tube exhaust apparatus of the present utility model, include a kind of transfusion drip tube exhaust apparatus, it is characterized in that: include the upside exhaust ports that is arranged on dropper the rubber needle sheaths that seals up dropper, thereby be provided with, can puncture the contact pin that needle guard makes the Bas Discharged external world in dropper in rubber needle sheaths, the lower end of described contact pin is provided with passage, upper end at contact pin is provided with venthole, is provided with the air duct that is communicated with them between described passage and venthole.
An exhaust apparatus, is characterized in that: flexible cover is overlapped in the upper end of described contact pin as mentioned above, is provided with the dustproof pore that stops dust to enter but can pass in and out air on resilient sleeve top, and described dustproof pore communicates with venthole.
An exhaust apparatus, is characterized in that: the external diameter of described contact pin is less than the bore of air vent as mentioned above.
An exhaust apparatus, is characterized in that: on described dustproof pore, be provided with airstrainer as mentioned above.
The beneficial effects of the utility model are: this utility model can be got rid of the unnecessary air in dropper, are provided with rubber sleeve sealing, and favorable sealing property is safe, utilizes contact pin to puncture rubber sleeve aerofluxus, easy to operate.
[accompanying drawing explanation]
Fig. 1 is that this utility model is arranged on using state figure on dropper.
Fig. 2 is this utility model structural representation (A place zoomed-in view).
[specific embodiment]
Below in conjunction with accompanying drawing, this utility model is described in detail:
As shown in the figure, a kind of transfusion drip tube exhaust apparatus, include upside air vent 41 places that are arranged on dropper 4 rubber needle sheaths 2 that seals up dropper 4, rubber needle sheaths 2 also can be used the material of other good springiness to make, thereby be provided with, can puncture the contact pin 1 that needle guard 2 makes the Bas Discharged external world in dropper 4 in rubber needle sheaths 2, the external diameter of described contact pin 1 is slightly less than the bore of air vent 41, contact pin 1 is inserted into 41 li of air vents and can stirs up and down, the lower end of contact pin 1 is provided with passage 11, in the upper end of contact pin 1, be provided with venthole 12, between described passage 11 and venthole 12, be provided with the air duct 13 that is communicated with them, flexible cover 3 is overlapped in the upper end of contact pin 1, resilient sleeve can be used to have elastic pipe or the elastic components such as spring are set in pipe and make, on resilient sleeve 3 tops, be provided with and stop dust to enter but can pass in and out for air the dustproof pore 31 of resilient sleeve (3), on dustproof pore 31, airstrainer is installed, can maintain contact pin 1 inner clean, avoid polluting, described dustproof pore 31 communicates with venthole 12 simultaneously.
Generally, while not needing air-out, the lower end of contact pin 1 is wrapped by rubber needle sheaths 2, dropper is inside and outside to be completely cut off and opens by rubber needle sheaths 1, air is not communicated with, when needs are discharged unnecessary air, be pressed into contact pin 1, needle point punctures rubber needle sheaths 2, enter dropper 4 inside, passage 11 is also exposed to the outside of rubber needle sheaths 2, dropper 4 inside and the external world are communicated with by passage 11, air is by passage 11, enter into air duct 13, again through venthole 12, dustproof pore 31 is discharged, while pressing, the air of resilient sleeve 3 inside also can be by dustproof pore 31 turnover, after drained, unclamp hands, contact pin 1 is under the effect of resilient sleeve 3, rebound and return to original position, rubber needle sheaths 2 wraps contact pin 1 again, rubber needle sheaths 2 is due to elasticity simultaneously, can restore again, the space that locking is punctured by contact pin 1, seal up the air vent 41 of dropper 4, stop medicinal liquid to enter.
Claims (4)
