Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a medical feces collecting device. Background Art

[0002] The detection of fecal samples is of great value in clinical diagnosis. In recent years, the research on intestinal microorganisms and human health has entered a new stage. The microorganisms in feces may be both potential diagnostic markers and good medicines for treating diseases. Therefore, the correct collection of fecal samples is particularly important. The current commercially available fecal collection devices are relatively simple and have many defects: there is no quantitative design, the collection volume may be too much or too little, and the quantitative collection of samples cannot be guaranteed. There is a lack of quantitative basis for the components and microorganisms to be detected; the sample is not isolated from the diluent or preservation solution, and the contact time cannot be controlled, resulting in the degradation of some target detection components due to premature dilution; the mixing ratio of the sample and the diluent or preservation solution cannot be controlled, resulting in inconsistent dilution ratios between samples; there is no mixing device; the sample diluent or preservation solution is prone to spillage.

[0003] The existing feces collection cannot collect samples quantitatively, resulting in excessive or insufficient collection. In addition, the collected feces are directly placed in containers, which may cause secondary contamination of the sampled samples, thereby affecting subsequent sample testing. Utility Model Content

[0018] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0019] See also Figure 1-4 A medical feces collection device comprises a mixing tube 1 with a sealing component at the opening position of the tube mouth, a collecting rod 7 that can be inserted into the mixing tube 1, and a collecting mechanism arranged on the collecting rod 7 to collect feces. The collecting mechanism comprises two collecting blocks 13 whose end faces are adjacent and the top end is rotatably connected to the bottom end of the collecting rod 7, a control component arranged on the top end of the collecting rod 7 and controlling the two collecting blocks 13 to move away from or approach each other, and a fixing component arranged on the rod body of the collecting rod 7 and fixedly connected to the position between the sealing component. The adjacent end faces of the two collecting blocks 13 are provided with collecting grooves, and the bottom wall of the collecting groove is provided with a plurality of through holes opened at equal intervals.

[0020] like Figure 1-4As shown, the collecting rod 7 is directly moved to the feces position, and then the two collecting blocks 13 arranged on the bottom end of the collecting rod 7 are driven to approach each other through the control component arranged on the collecting rod 7, so as to facilitate the quantitative collection of feces by opening the collecting grooves on the adjacent end faces of the two collecting blocks 13. After the feces are quantitatively collected, the collecting rod 7 is directly inserted into the mixing tube 1, and the opening position of the mixing tube 1 is sealed by the sealing component arranged at the opening position of the mixing tube 1, so that the feces samples can be conveniently collected quantitatively and the samples can be sealed and stored, so as to avoid the secondary contamination of the sampled samples and ensure the detection accuracy of the subsequent sampled samples.

[0021] The top ends of the two collection blocks 13 are rotatably connected to the two sides of the bottom end of the collection rod 7 through a rotating shaft. The control component includes a control rod 9 movably inserted into a control groove 17 opened inside the rod body of the collection rod 7, a control block 10 arranged on the top end surface of the control rod 9, two transmission rods 22 whose top ends are rotatably connected to the bottom ends of the control rod 9 and whose bottom ends are respectively fixedly connected to different rotating shafts, and an elastic member arranged in the control groove 17 and connected to the control rod 9. The transmission rod 22 is a telescopic rod structure.

[0022] like Figure 2-4 As shown, when it is necessary to control the two collection blocks 13 to move away from each other, the control block 10 is pressed to move in the direction of the collection rod 7, so that the rotating ends of the two transmission rods 22 are driven by the control rod 9 to move in the direction of the collection rod 7, so that it is convenient to drive the two rotating shafts of the transmission rod 22 to rotate, so as to drive the two collection blocks 13 away from each other, and then collect feces, move the two collection blocks 13 to the feces, and then release the control block 10, and drive the control rod 9 to move upward through the elastic member, so as to drive the two collection blocks 13 to approach each other through the two transmission rods 22, so as to facilitate the quantitative collection of feces through the collection groove opened on the adjacent end face of the collection block 13, so that the feces samples can be conveniently collected quantitatively, and the samples are sealed and stored, so as to avoid the secondary contamination of the sampled samples and ensure the detection accuracy of the subsequent sampled samples.

[0023] like Figure 4As shown, the elastic member includes a sliding block 21 movably inserted into the control groove 17 and fixedly sleeved on the rod body of the control rod 9, a fixed block 20 movably sleeved on the rod body of the control rod 9 and fixedly arranged on the top of the collection rod 7, and a return spring 19 movably sleeved on the rod body of the control rod 9 and with two ends respectively connected to the adjacent end faces of the sliding block 21 and the fixed block 20, wherein the return spring 19 is compressed after the control rod 9 moves downward, and when it is necessary to collect feces through the two collection blocks 13, the control rod 9 is released again. At this time, the compressed return spring 19 will drive the control rod 9 to move upward, so as to facilitate the quantitative collection of feces by driving the two collection blocks 13 through the two transmission rods 22, so that the feces samples can be conveniently collected quantitatively, and the samples can be sealed and stored, so as to avoid the secondary contamination of the sampled samples and ensure the detection accuracy of the subsequent sampled samples.

[0024] The sealing assembly includes two sealing plates 6 symmetrically arranged at the opening position of the mixing tube 1, and an adjusting member arranged on the tube body of the mixing tube 1 and controlling the two sealing plates 6 to move closer to or away from each other. A snap-in groove matching the tube body of the mixing tube 1 is provided on the adjacent side surfaces of the two sealing plates 6.

[0025] The adjusting member includes two limit bars 2 symmetrically arranged on both sides of the mixing tube 1 and arranged in the vertical direction, a sliding rod 16 arranged in a lifting groove 15 opened along the length direction of the rod body on the side away from each other of the two limit bars 2, a lifting block 3 sleeved on the rod body of the sliding rod 16 and located at the bottom of the sliding rod 16, a lifting spring sleeved on the rod body of the sliding rod 16 and connected to the lifting block 3 and the groove wall of the lifting groove 15 at both ends, a control rod 5 fixedly arranged on the bottom end surface of the sealing plate 6, and a linkage rod 4 whose two ends are rotatably connected to the top end surface of the lifting block 3 and the end of the control rod 5 away from the sealing plate 6.

[0026] like Figure 2-3 As shown, when the collecting rod 7 needs to be inserted into the mixing tube 1, it is first moved upward through the lifting block 3. At this time, the lifting block 3 will slide on the sliding rod 16 to compress the lifting spring on the rod body of the sliding rod 16. At this time, the control rod 5 is driven by the linkage rod 4 arranged on the lifting block 3 to move to the opening position away from the mixing tube 1, so as to facilitate driving the two sealing plates 6 arranged on the tube mouth of the mixing tube 1 to move away from each other, so as to facilitate the collection rod 7 to be inserted into the mixing tube 1, and then the lifting block 3 is released. The elastic force of the lifting spring on the rod body of the sliding rod 16 is used to facilitate driving the lifting block 3 to move downward, so as to facilitate driving the two sealing plates 6 to approach each other through the linkage rod 4, so as to facilitate the two sealing plates 6 to be sealed at the tube mouth of the mixing tube 1, and the samples are sealed and stored, thereby avoiding the secondary contamination of the sampled samples and ensuring the detection accuracy of the subsequent sampled samples.

[0027] The fixing assembly includes a fixing ring fixedly mounted on the collecting rod body, a rotating ring 12 rotatably mounted on the outer ring surface of the fixing ring 11, and clamping blocks 18 arranged in a circular array on the bottom end surface of the rotating ring 12. The clamping blocks 18 arranged on the bottom end surface of the rotating ring 12 match the clamping grooves 14 opened on the top end surfaces when the two sealing plates 6 are fitted together.

[0028] like Figure 2-3 As shown, when the collecting rod 7 is inserted into the mixing tube 1, the two sealing plates 6 are close to each other and are sleeved on the collecting rod 7 through the clamping grooves provided on the sealing plates 6, so that the nozzle position of the mixing tube 1 is sealed by the two sealing plates 6. At this time, the collecting rod 7 is pressed downward to facilitate the clamping block 18 provided on the bottom end face of the rotating ring 12 to be inserted into the clamping groove 14 provided on the end faces of the two sealing plates 6. On the one hand, it is convenient to fix the position between the two sealing plates 6, and on the other hand, it is also convenient to position the collecting rod 7 in the mixing tube 1.

[0029] An auxiliary block 8 is arranged on the top end of the rod shaft of the collecting rod 7 .
