Utility model content

The applicant is directed to the problem of above-mentioned, has carried out Improvement, there is provided and a kind of rectum sampler is simple in structure tight Gather, easy to operate health, rectum epimere content is sampled directly from the rectum of patient, avoids anus stomatorrhagia, anal fissure, hemorrhoid Etc. pollution of the lesion to sampling thing, it is ensured that the accuracy of inspection result.

In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme：

A kind of rectum sampler, includes the intubation of circular tube shaped, and the rear end of the intubation is connected with handle, and plug is arranged on In the mouth of pipe of the intubation front end；Thief rod is slidably connected the handle, and the rear end of the thief rod is equipped with push handle, the sampling The front end of bar extends into the intubation, and the front end of the thief rod is equipped with sampling portion；Resetting spring is sleeved on described take On sample bar, and the both ends of the resetting spring are against between the push handle and the handle.

Further：

The intubation includes fixed part and cannula portion, and the fixed part is fixedly connected with the handle, behind described sleeve pipe portion End cap is interference fit between described sleeve pipe portion and the fixed part outside the fixed part；The thief rod includes sliding Portion and inserted link portion, the outer end of the sliding part are fixedly connected with the push handle, and the inner of the sliding part is equipped with axial jack, institute The straight slot that radial direction is equipped with the jack of sliding part is stated, inserted link portion the inner plug-in card is inserted in the described of sliding part the inner Kong Zhong.

The sampling portion is medical cotton ball or medical sponge.

The sampling portion is the groove for the front end for being arranged on the thief rod.

The plug is medical cotton ball or medical sponge.

The front end mouth of pipe of the intubation is equipped with fillet.

The push handle and the handle are in strip.

The utility model has technical effect that：

A kind of rectum sampler, simple and compact for structure disclosed in the utility model, easy to operate health, directly from patient's Rectum epimere content is sampled in rectum, avoids pollution of the lesions such as anus stomatorrhagia, anal fissure, hemorrhoid to sampling thing, it is ensured that inspection Test the accuracy of result.

Embodiment

Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, 2, the utility model includes intubation 1, and intubation 1 is cylindrical, and the rear end for being intubated 1 is connected with handle 3, Plug 7 is arranged in the mouth of pipe of 1 front end of intubation, and plug 7 is medical cotton ball or medical sponge.Thief rod 2 is slidably connected hand Handle 3, the rear end of thief rod 2 are equipped with push handle 4, and the front end of thief rod 2 extends into intubation 1, and the front end of thief rod 2 is equipped with and takes Sample portion 6, sampling portion 6 are medical cotton ball or medical sponge, and sampling portion 6 can also be the groove for the front end for being arranged on thief rod 2. Resetting spring 5 is sleeved on thief rod 2, and the both ends of resetting spring 5 are against between push handle 4 and handle 3.Push handle 4 and handle 3 For hand-held, push handle 4 and handle 3 can be rounded, in order to save material, reduce cost, and more convenient operation, this implementation In example, push handle 4 and handle 3 are in strip.In sampling operation, medical cotton ball or medical sponge as sampling portion dip a small amount of Rectum epimere content, or a small amount of rectum epimere content is extracted by the groove of the front end of the thief rod 2 as sampling portion, it is multiple Position spring 5 is used for the reset of thief rod 2 and push handle 4, and plug 7 can prevent that pollutant is to sampling in the insertion rectal procedures of intubation 1 Portion 6 pollutes.

When being sampled operation, medical staff's hand-held handle 3, rectum is inserted into by anus of the front end through patient for being intubated 1, The front end mouth of pipe of intubation 1 is equipped with fillet 8, can prevent from during insertion patient being caused to damage, and the front end for being intubated 1 reaches rectum During epimere suitable position（Also proctoscope auxiliary observation can be used）, push handle 4 is promoted, 4 compression reseting spring 5 of push handle simultaneously makes thief rod 2 The plug 7 being intubated in the mouth of pipe of 1 front end is pushed into rectum by extension, the sampling portion 6 of 2 front end of thief rod（Plug 7 can be in defecation When excrete）, the sampling portion 6 of 2 front end of thief rod stretches out the mouth of pipe of 1 front end of intubation, extracts rectum epimere content；Extract Cheng Hou, decontrols push handle 4, and under the action of resetting spring 5, the sampling portion 6 of 2 front end of thief rod retracts in intubation 1, at this moment can incite somebody to action Intubation 1 is transferred to, and completes sampling operation, and the rectum epimere content that sampling portion 6 extracts can be used as test samples, for examining, In whole sampling process, under the protection of intubation 1 and plug 7, sampling portion 6 will not touch to be gone out existing for patient's anal orifice The lesions such as blood, anal fissure, hemorrhoid, will not pollute sampling, it is ensured that the accuracy of inspection result.

In the above-described embodiment, the component that handle 3 is integrated with intubation 1, push handle 4 are integrated component with thief rod 2, It is made of medical plastic, can only be disposable, use cost is higher.

It is the second embodiment of the utility model as shown in Figure 3,4, intubation 1 includes fixed part 11 and cannula portion 12, fixed Portion 11 is fixedly connected with handle 3, and fixed part 11 is integrally formed component with handle 3, and the rear end of cannula portion 12 is sleeved on outside fixed part 11, It is interference fit between cannula portion 12 and fixed part 11, cannula portion 12 is connected firmly with fixed part 11 in use, together When cannula portion 12 can also be removed from fixed part 11.Thief rod 2 includes sliding part 21 and inserted link portion 22, and sliding part 21 is slidably connected hand Handle 3, the outer end of sliding part 21 are fixedly connected with push handle 4, and sliding part 21 is integrally formed component with push handle 4, and the inner of sliding part 21 is set There is axial jack 23, the straight slot 24 of radial direction is equipped with the jack 23 of sliding part 21, the inner plug-in card in inserted link portion 22 is in sliding part 21 Inner jack 23, the diameter of jack 23 are slightly less than the diameter in inserted link portion 22, so the elastic force of material in itself can be relied on to clamp Inserted link portion 22, while inserted link portion 22 can also be transferred to from jack 23.

The sampling operation process of the present embodiment is identical with previous embodiment, after the completion of sampling operation, the intubation 1 that more renews Cannula portion 12 and the inserted link portion 22 of thief rod 2 can carry out the sampling of next patient, escapable cost, reduces and wastes.
