Description
Technical field
This utility model relates to a kind of gynecological sampler, belongs to gynecologic operating instruments field.
Background technology
At present, when carrying out gynecologial examination to patient, the frequent vaginal secretions that need to gather is done further and is made a definite diagnosis clinically, prior art is mainly to adopt swab stick to wipe to get secretions, cotton balls can adsorb a large amount of samples like this, and in taking out swab stick process, in the sample gathering before easily other materials being sneaked into, thereby the accuracy of impact sampling, finally check result is brought to interference, severe patient can be diagnosed by delay treatment, to medical worker, has increased great work difficulty.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of rational in infrastructure, easy and simple to handle and can improve the gynecological sampler of sampling accuracy.
Gynecological sampler described in the utility model, comprise sleeve pipe, control handle, connecting rod and the sampling part that is positioned at sleeve pipe, sleeve pipe is by upper tube body, lower tube body is threaded and forms, the bottom suit control handle of lower tube body, on lower tube body, be also provided with bar hole, bar hole is positioned at control handle top, the inner side fixing lug boss of control handle, corresponding boss arranges bar shaped gathering sill on the outer wall of lower tube body, boss snaps in bar shaped gathering sill and along bar shaped gathering sill and moves, connecting rod one end is welded on the upper end of control handle, the other end is threaded from bar hole threading inside and with sampling part, the bottom of sampling part has sampling inner chamber, the top of sampling part is arc sampling plate, on the interior concaved circular cambered surface of arc sampling plate, guiding gutter is set, guiding gutter lower end is communicated with sampling inner chamber.
The guide pad of left and right two symmetries is set on above-mentioned internal surface of sleeve pipe, and connecting rod passes the space between two guide pads, by guide pad, can realize the guiding to connecting rod, can guarantee the stability of its motion simultaneously.
In above-mentioned control handle and the space of lower tube body, back-moving spring is installed, corresponding back-moving spring arranges limited block on lower tube body, and limited block is positioned at the upper end of back-moving spring.Promote forward control handle, can drive arc sampling plate to move forward, after sampling, loose one's grip, in control handle, under the elastic force of back-moving spring, can drive arc sampling plate to set back, easy and simple to handle, avoid sampling rear arc sampling plate and be exposed at other materials that jacket exterior causes and sneak into the problem in collecting sample, make sampling more accurate.
Operation principle and process:
During sampling, first the sleeve pipe of built-in arc sampling plate is stretched in vagina, then promote forward control handle, drive arc sampling plate to move forward, arc sampling plate is stretched out from sleeve pipe upper end, to gather vaginal secretions, the vaginal secretions collecting enters in the sampling inner chamber of sampling part along guiding gutter, after sampling, looses one's grip, and arc sampling plate is retracted in sleeve pipe automatically, afterwards sampler is taken out, complete sampling.
Because arc sampling plate is all positioned at inside pipe casing before sampling and after sampling, therefore can avoid other materials to sneak into, make sampling more accurate, guarantee check result.
After sampling, rotation upper tube body is supreme, lower tube body is separated, then the sampling part on connecting rod top is taken off and sends to check, wherein sampling part is the disposable appliance that makes, before every sub-sampling, new sampling part is installed, had both been guaranteed the accuracy of sampling, can prevent cross infection again, be applicable to clinical use.
The beneficial effect that this utility model compared with prior art had is:
This gynecological sampler reasonable in design, because arc sampling plate is all positioned at inside pipe casing before sampling and after sampling, therefore can avoid other materials to sneak into, and makes sampling more accurate, guarantees check result; Sampling part is threaded with connecting rod, and new sampling part is installed, and has both guaranteed the accuracy of sampling, can prevent cross infection again, is applicable to clinical use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the syndeton schematic diagram of lower tube body and control handle;
Fig. 3 is the A-A profile of Fig. 2.
In figure: 1, arc sampling plate; 2, guiding gutter; 3, sampling inner chamber; 4, sampling part; 5, connecting rod; 6, upper tube body; 7, lower tube body; 8, guide pad; 9, bar hole; 10, control handle; 11, limited block; 12, back-moving spring; 13, boss; 14, bar shaped gathering sill.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figures 1 to 3, this gynecological sampler comprises sleeve pipe, control handle 10, connecting rod 5 and the sampling part 4 that is positioned at sleeve pipe, sleeve pipe is by upper tube body 6, lower tube body 7 is threaded and forms, the bottom suit control handle 10 of lower tube body 7, on lower tube body 7, be also provided with bar hole 9, bar hole 9 is positioned at control handle 10 tops, the inner side fixing lug boss 13 of control handle 10, corresponding boss 13 arranges bar shaped gathering sill 14 on the outer wall of lower tube body 7, boss 13 snaps in bar shaped gathering sill 14 and along bar shaped gathering sill 14 and moves, connecting rod 5 one end are welded on the upper end of control handle 10, the other end is inner and be threaded with sampling part 4 from bar hole 9 threadings, the bottom of sampling part 4 has sampling inner chamber 3, the top of sampling part 4 is arc sampling plate 1, on the interior concaved circular cambered surface of arc sampling plate 1, guiding gutter 2 is set, guiding gutter 2 lower ends are communicated with sampling inner chamber 3.
