Description

TECHNICAL FIELD

[0001] The utility model relates to medical detection field, concretely relates to a kind of pretreatment equipment of respiratory system marker detection sample. BACKGROUND

[0002] In the diagnosis and research of respiratory system diseases, the detection of respiratory system markers is crucial. Common detection samples include sputum, alveolar lavage fluid, blood, etc. However, these samples usually need to be pretreated before detection to improve the accuracy and reliability of detection.

[0003] Currently, traditional manual shaking or simple stirring methods have obvious deficiencies in fully liquefying sputum. Therefore, people generally use a shaker to process sputum. However, in the process of liquefying sputum using a shaker, the liquefaction degree of sputum is mainly judged by observation. Sputum that is not fully liquefied usually appears in clumps, flocculation, or thick jelly. The texture is extremely uneven. Fully liquefied sputum appears uniform and thin, similar to the texture of rice soup or milk. However, this observation-based judgment method is greatly influenced by subjective factors. Different operators may have different observations and experience, which may lead to deviations in judging the liquefaction state of sputum, making it difficult to ensure the accuracy of judgment.

[0004] Therefore, a pretreatment device for respiratory system marker detection samples is proposed. UTILITY MODEL CONTENT

[0005] In view of the above problems existing in the pretreatment of respiratory system marker detection samples, the utility model is proposed.

[0006] Therefore, the utility model aims to provide a pretreatment device for respiratory system marker detection samples, which solves the problems raised in the background art.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions:

[0008] A pretreatment device for respiratory system marker detection samples, comprising a shaking machine body, a shaking shaft and a shaking plate arranged inside the shaking machine body, the shaking plate is rotatably arranged between the two shaking shafts, and a limiting mechanism is arranged between the shaft wall of one of the shaking shafts and the shaking plate.

[0009] The surface of the shaking plate is provided with a plurality of uniformly distributed placing holes, and the inside of the placing hole is provided with a sample test tube, and the inside of the placing hole is provided with a clamping mechanism for fixing the sample test tube.

[0010] The opening of the sample test tube is provided with a plugging head, the bottom of the plugging head is fixedly provided with a sealing rubber plug extending into the inside of the sample test tube, the bottom of the plugging head is provided with a liquid leakage hole, and the inside of the liquid leakage hole is fixedly provided with a filter screen.

[0011] Preferably, the limiting mechanism comprises a limiting disc fixedly arranged on the shaft wall of the oscillation shaft, a limiting bolt is inserted on one side of the limiting disc, a limiting sleeve is fixedly arranged on one side of the upper surface of the oscillation plate, the limiting bolt and the limiting sleeve are both magnetic structures, and the limiting bolt and the limiting sleeve are magnetically inserted and matched.

[0012] Preferably, the clamping mechanism comprises two clamping plates symmetrically arranged in the placement hole, and springs are fixedly arranged between one side of the two clamping plates and the inner wall of the placement hole.

[0013] Preferably, the clamping plate is an arc-shaped rubber plate, and the inner wall of the clamping plate is matched with the outer wall of the sample test tube.

[0014] Further, the lower surface of the oscillation plate is fixedly provided with a bottom support, and the bottoms of the plurality of sample test tubes are placed in the inside of the bottom support.

[0015] Preferably, the inside of the oscillation machine body is provided with an oscillation assembly connected with one end of the two oscillation shafts.

[0016] In the above technical solution, the technical effects and advantages of the utility model are as follows:

[0017] 1. The utility model discloses a sealing rubber plug and a filter screen arranged at the opening of the sample test tube, the sealing rubber plug ensures the sealing property of the sample test tube, prevents sample leakage and foreign matter from mixing into the outside, maintains the purity of the sample, and the combination of the liquid leakage hole and the filter screen can rotate the oscillation plate after oscillation for a period of time, so that the sputum in the sample test tube is filtered through the filter screen. If the sputum can smoothly pass through the filter screen and the solid impurities remaining on the filter screen are less, it indicates that the liquefaction effect of the sputum is better.

[0018] 2. The utility model discloses a limiting disc, a limiting bolt and a limiting sleeve arranged between the oscillation shaft and the oscillation plate. When it is necessary to rotate the oscillation plate, the medical staff pulls the limiting bolt first, so that the limiting bolt moves out of the inside of the limiting sleeve. At this time, the limiting fixing between the oscillation plate and the oscillation shaft is released, so that the oscillation plate can be rotated around the oscillation shaft. On the contrary, the limiting disc, the limiting bolt and the limiting sleeve can fix the position of the oscillation plate around the oscillation shaft.

[0019] 3. The utility model discloses a clamping plate and a spring. Since the oscillation plate and the sample test tube need to be turned over, the spring applies an elastic force to the clamping plate, so that the clamping plate clamps and fixes the sample test tube, thereby increasing the stability of the sample test tube.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figures 1-3 The device shown is a pretreatment device for respiratory system marker detection samples, including a shaking body 1 and a shaking shaft 2 and a shaking plate 3 disposed inside the shaking body 1. The shaking plate 3 is rotatably disposed between the two shaking shafts 2. The shaking body 1 is provided with a shaking assembly (the specific structure is not described in detail in the figure) connected to one end of the two shaking shafts 2. A limiting mechanism is provided between the shaft wall of one of the shaking shafts 2 and the shaking plate 3.

[0030] The surface of the oscillation plate 3 is provided with a plurality of placement holes 4 which are uniformly distributed, and a sample test tube 5 is arranged in each of the placement holes 4. A clamping mechanism is arranged in each of the placement holes 4 for fixing the sample test tube 5. A bottom support 15 is fixed to the lower surface of the oscillation plate 3, and the bottoms of the plurality of sample test tubes 5 are arranged in the bottom support 15, so that the plurality of sample test tubes 5 can be supported.

[0031] A stopper 6 is arranged at the opening of the sample test tube 5. The bottom of the stopper 6 is fixedly provided with a sealing rubber plug 7 which extends into the sample test tube 5. A liquid leakage hole 8 is arranged in the bottom of the stopper 6, and a filter screen 9 is fixedly arranged in the liquid leakage hole 8. When it is necessary to determine the liquefaction effect of sputum, the oscillation plate 3 is rotated. At this time, the sputum in the sample test tube 5 flows to the stopper 6 under the action of gravity. If the sputum can smoothly pass through the filter screen 9 in the liquid leakage hole 8 in the bottom of the stopper 6, and the solid impurities remaining on the filter screen are less, it indicates that the liquefaction effect of the sputum is better.

[0032] As shown in Figure 2 and 5 limiting mechanism includes a limiting disc 10 fixedly arranged on the shaft wall of the oscillation shaft 2. A limiting pin 11 is insertedly arranged on one side of the limiting disc 10. A limiting sleeve 12 is fixedly arranged on one side of the upper surface of the oscillation plate 3. The limiting pin 11 and the limiting sleeve 12 are both of magnetic structure, and the limiting pin 11 and the limiting sleeve 12 are magnetically insertedly matched.

[0033] As shown in Figure 3 the clamping mechanism includes two clamping plates 13 which are symmetrically arranged in the placement hole 4. A spring 14 is fixedly arranged between one side of each of the two clamping plates 13 and the inner wall of the placement hole 4. The clamping plate 13 is of arc-shaped rubber plate, and the inner wall of the clamping plate 13 is matched with the outer wall of the sample test tube 5. When the sample test tube 5 is arranged in the placement hole 4, the clamping plate 13 extrudes the spring 14 outward, so that the sample test tube 5 can be clamped and fixed.

[0034] In use, the sample test tube 5 is arranged in the placement hole 4 of the oscillation plate 3. The clamping plate 13 tightly clamps the sample test tube 5 under the elastic force of the spring 14. Since the clamping plate 13 is of arc-shaped rubber plate, the inner wall of the clamping plate 13 is perfectly matched with the outer wall of the sample test tube 5, so that the friction force is increased. Not only the sample test tube can be effectively prevented from shaking and shifting during the oscillation, but also the damage of the sample test tube caused by the hard contact is avoided. At the same time, the bottom support 15 on the lower surface of the oscillation plate 3 provides additional support for the sample test tube 5, so that the stability of the sample test tube is further enhanced.

[0035] The sample test tube 5 is provided with a sealing head 6 at the opening, and a sealing rubber plug 7 at the bottom of the sealing head 6 is inserted into the sample test tube 5 to ensure the sealing of the sample test tube, prevent sample leakage and foreign matter from mixing, and maintain the purity of the sample. When the sample is subjected to shock pretreatment, the sputum gradually liquefies with the shock. When the liquefaction effect of the sputum needs to be determined, the shock plate 3 can be rotated, and at this time, the sputum in the sample test tube 5 flows to the sealing head 6 under the action of gravity. If the sputum can smoothly pass through the filter screen 9 in the leakage hole 8 at the bottom of the sealing head 6, and there are less solid impurities on the filter screen, it indicates that the liquefaction effect of the sputum is good.

[0036] The shock plate 3 is rotationally arranged between the two shock shafts 2, and a limiting mechanism is arranged between the shaft wall of one of the shock shafts 2 and the shock plate 3. When the medical staff needs to adjust the angle of the shock plate 3, the hand first pulls the limiting pin 11 out of the limiting sleeve 12, at this time, the limiting fixation between the shock plate 3 and the shock shaft 2 is released, and the shock plate 3 can rotate around the shock shaft 2. After adjusting the angle, the limiting pin 11 is released, and under the action of magnetism, the limiting pin 11 is inserted into the limiting sleeve 12 again, and the position of the shock plate 3 around the shock shaft 2 is fixed, so that the sample receives consistent shock conditions each time.

[0037] The shock assembly (the specific structure is not described in detail in the figure) in the shock machine body 1 is connected with one end of the two shock shafts 2. After the shock assembly is started, the shock shaft 2 is driven to rotate, and then the shock plate 3 rotates, and the sample test tube 5 and the sample in the sample test tube 5 placed on the shock plate 3 also shake. During the shock process, the sputum in the sample test tube 5 gradually liquefies under the action of shock, and the pretreatment of the sample for respiratory system marker detection is realized.

[0038] The above only describes some exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
