Abstract
The utility model relates to a cover of a storage tank used for a handheld first-aid aspirator and belongs to the field of medical instruments. The utility model consists of a cover body (1) and is characterized in that a suction inlet (2) and a vacuumizing opening (3), are arranged on the cover body (1); a baffle (4) which is used for preventing the suction liquid from entering the vacuumizing opening (3) is arranged between the suction inlet (2) and the vacuumizing opening (3). The utility model has the advantages of simple structure, low cost, convenient operation, safety and hygiene.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of liquid suction pump, specifically a kind of hand-held first aid suction pump fluid reservoir cover.
Background technology
As everyone knows, in treatment and first aid process, need a large amount of all kinds of suction pumps that use.The suction pump that uses has two classes at present, one class is the electrodynamic type vacuum extractor, another kind of is foot-operated vacuum extractor, the ubiquitous problem of this two classes suction pump is that volume is big, the cost height, use and carry all very inconvenient, especially at first aid scene and ambulance vehicles, can't use in the airborne vehicle at all, therefore it is little to be badly in need of a kind of volume, hand-held vacuum extractor easy to use uses under the state of emergency, for easy to use, fluid reservoir as one of this type of hand-held vacuum extractor critical component must be able in time be changed, and in order to change conveniently, must design a kind of cover that is connected with depression generator (being generally cylinder), and according to the knowledge of the applicant, still not having similar products like at present can be for selecting for use.
Summary of the invention
The purpose of this utility model is a kind of hand-held first aid suction pump fluid reservoir cover of design.
The technical solution of the utility model is:
A kind of hand-held first aid suction pump fluid reservoir cover comprises lid 1, it is characterized in that lid 1 is provided with suction inlet 2 and vacuum orifice 3, is provided with the baffle plate 4 that prevents to be entered by imbibition in the vacuum orifice 3 between suction inlet 2 and vacuum orifice 3.
Described baffle plate 4 is an arcuate structure, is preferably the semicircular arc structure, and its height should surpass suction inlet 2.
The opening inboard of described lid 1 is provided with the female thread that links to each other with tank body.
Described vacuum orifice 3 is made up of the horizontal segment 301 and the vertical section 302 of vertical perforation mutually, and the air inlet 303 of vacuum orifice 3 is positioned on the vertical section 302.
Described air inlet 303 is the side direction air inlet.
Described vertical section 302 is the through hole of a up/down perforation, and its upper end plug is equipped with bulb latch 5, and bulb latch 5 links to each other with an end of connection strap 6, and the other end of connection strap 6 is fixed on the upper surface of loam cake 1.
The beneficial effects of the utility model:
The utlity model has simple in structurely, easy to use, especially, can prevent effectively that absorbate from entering in the negative pressure generator at rear portion, solved the cross infection problem of negative pressure generator by using baffle plate.
This utility model also has advantage of low manufacturing cost, can be by the injection moulding one-shot forming, and the mode that the vertical section 302 in the vacuum orifice 3 wherein can adopt through hole to add a cover is realized (shown in Fig. 1,3).
This utility model provides the accessory of being badly in need of for hand-held first aid suction pump.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of looking up of Fig. 1.
Fig. 3 is the plan structure sketch map of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further described.
As shown in Figure 1, 2, 3.
A kind of hand-held first aid suction pump fluid reservoir cover, comprise lid 1, the opening inboard of lid 1 is provided with the female thread that links to each other with tank body, lid 1 is provided with suction inlet 2 and vacuum orifice 3, between suction inlet 2 and vacuum orifice 3, be provided with the baffle plate 4 that prevents to be entered in the vacuum orifice 3, as shown in Figure 1 by imbibition.Baffle plate 4 is an arcuate structure, is preferably semicircular arc structure (as Fig. 2), and its height should surpass suction inlet 2 (see figure 1)s.Described vacuum orifice 3 is made up of the horizontal segment 301 and the vertical section 302 of vertical perforation mutually, and the air inlet 303 of vacuum orifice 3 is positioned on the vertical section 302, and described air inlet 303 is the side direction air inlet.For easily manufactured, the mode that vertical section 302 can adopt through hole to add bulb latch 5 is realized (shown in Fig. 1,3), and bulb latch 5 links to each other with the upper surface of lid 1 by a connection strap 6.
Work process of the present utility model is:
When negative pressure generator was worked, the air in the fluid reservoir was extracted out from vacuum orifice 3, produces negative pressure in the fluid reservoir, and at this moment, sucked liquid enters the lid 1 from suction inlet under the effect of negative pressure, and the effect that runs into baffle plate 4 directly falls into fluid reservoir.
This utility model does not relate to the part prior art that maybe can adopt same as the prior art to be realized.
