Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a sputum testing sampler. Background Technology
[0002] Sputum test data is one of the important bases for clinicians to assess a patient's health status. Generally, sputum is coughed up by the patient, collected in a container by laboratory personnel, labeled, and tested to generate a report. A sputum sampler is needed when collecting sputum. Current sputum samplers used in laboratories require pressing an air bladder to draw up the sputum. During operation, if the air bladder is not pressed and one end of the sampler is inserted directly into the sputum, pressing the air bladder again can cause the sputum to be squeezed and dispersed, or even splash, making it more difficult to collect a second sample. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies where, if the airbag is not pressed and one end of the sampler is inserted directly into the sputum, pressing the airbag again will cause the sputum to be squeezed and dispersed, making it more difficult to sample the sputum again. Therefore, this invention provides a sputum testing sampler.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design a sputum sampler, including a long tube with one end shaped like a frustum. A piston is installed inside the long tube, and a push-pull assembly is installed at the piston. A sealing block is slidably installed at one end of the long tube, and the vertical projection of the piston is located on the sealing block. An adjustment assembly is installed at the sealing block to adjust the sealing performance of one end of the long tube. A sleeve is connected to the outside of the long tube, and a groove is opened on one side of the top of the sleeve. A moving block is slidably installed on the groove, and a connecting rod is installed between one side of the moving block and one side of the piston. The connecting rod is curved.
[0006] Preferably, a fixing ring is fitted on the outer side of the movable block, both ends of the fixing ring are arc-shaped, and anti-slip texture is provided on the outer side of the fixing ring.
[0007] Preferably, one end of the connecting rod is located inside the groove, and the edge of the groove is arc-shaped.
[0008] Preferably, the adjusting assembly includes a crossbar mounted on the long tube, the vertical projection of the piston is located on the crossbar, an elastic element is provided on one side of the crossbar, and one end of the elastic element is connected to the sealing block.
[0009] Preferably, a limiting rod is installed on the sealing block, one end of the limiting rod passes through the crossbar, and the elastic element is sleeved on the limiting rod.
[0010] Preferably, one end of the sleeve is provided with several anti-slip grooves.
[0011] Preferably, one end of the sleeve is connected to a protective sleeve, and one end of the long tube is located inside the protective sleeve.
[0012] The sputum sampler proposed in this utility model has the following advantages: the sputum sampler moves on a moving block within a groove, causing the moving block to move along with a connecting rod. The connecting rod, in turn, moves a piston within a long tube, allowing the device to suck up sputum. Once the sputum enters the long tube, it avoids the air bladder causing air bubbles and splashing. The elastic element pulls the sealing block, preventing sputum from easily seeping out from the bottom of the long tube, thus ensuring that the sample is not easily contaminated.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Example 1: Refer to Figure 1-3A sputum sampler includes a long tube 1, one end of which is truncated cone-shaped. A piston 2 is installed inside the long tube 1, and a push-pull assembly is installed at the piston 2. A sealing block 3 is slidably installed at one end of the long tube 1. The vertical projection of the piston 2 is located on the sealing block 3. An adjustment assembly is installed at the sealing block 3. The adjustment assembly includes a crossbar 9 installed on the long tube 1. The vertical projection of the piston 2 is located on the crossbar 9. An elastic element 10 is installed on one side of the crossbar 9. One end of the elastic element 10 is connected to the sealing block 3. The adjustment assembly adjusts the sealing performance of one end of the long tube 1 by the sealing block 3. A sleeve tube 4 is connected to the outside of the long tube 1. A groove 5 is opened on one side of the top of the sleeve tube 4. A moving block 6 is slidably installed on the groove 5. A connecting rod 7 is installed between one side of the moving block 6 and one side of the piston 2. The connecting rod 7 is curved.
[0019] Usage: After the operator holds the sleeve tube 4, the operator presses the moving block 6 with their thumb, causing the moving block 6 to move within the slide groove 5. This causes the moving block 6 to move along with the connecting rod 7, which in turn moves the piston 2 within the long tube 1. During the movement of the piston 2, a negative pressure is created in the area between the piston 2, the long tube 1, and the sealing block 3. This causes the sealing block 3 to squeeze the elastic element 10, allowing the device to suck up the sputum. This prevents the air bladder from causing air bubbles and splashing of the sputum. After the sputum enters the long tube 1, the elastic element 10 will pull the sealing block 3 when the operator does not move the fixing ring 8, making it difficult for the sputum to seep out from the bottom of the long tube 1, thus ensuring that the sample is not easily contaminated.
[0020] Example 2: In Example 1, the volume of the moving block 6 is relatively small, making it difficult for the operator to move it. Based on Example 1, optimizations are made, referencing... Figure 1-3 A fixing ring 8 is fitted on the outside of the movable block 6. Both ends of the fixing ring 8 are arc-shaped. Anti-slip texture is provided on the outside of the fixing ring 8. One end of the connecting rod 7 is located in the slide groove 5. The edge of the slide groove 5 is arc-shaped. A limiting rod 11 is installed on the sealing block 3. One end of the limiting rod 11 passes through the crossbar 9. The elastic element 10 is fitted on the limiting rod 11. Several anti-slip grooves 12 are provided on one end of the sleeve tube 4. A protective sleeve 13 is connected to one end of the sleeve tube 4. One end of the long tube 1 is located in the protective sleeve 13.
[0021] The fixed ring 8 is slidably set on the outside of the sleeve tube 4, so that after the operator holds the sleeve tube 4 at several anti-slip grooves 12, the operator can easily push the fixed ring 8 with his thumb. The fixed ring and the moving block 6 slide in the groove 5, which reduces the difficulty of moving the piston 2 in embodiment 1, and thus reduces the difficulty of operating the device.
[0022] The limiting rod 11 prevents the elastic element 10 from bending to the side, thus extending the service life of the elastic element 10. The protective sleeve 13 can protect the bottom area of the long tube 1, thereby extending the service life of the device.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
