Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a specimen collection device for a pathology department. Background Art

[0002] Specimen collection in the pathology department is an important part of medical diagnosis, which involves obtaining biological samples from the patient's body for histological, cytological or biochemical analysis to help doctors make accurate diagnoses. The most common is the sealed sputum cup, which is mainly used to collect and preserve sputum specimens and has good sealing properties to prevent contamination.

[0003] At present, most disposable sputum cups for testing are divided into a cup body and a detachable cup lid. After the cup lid is opened to collect sputum, the cup lid is tightened and then unscrewed for subsequent testing. Especially when collecting sputum through a dropper, medical staff need to remove the cup lid and completely open the top of the cup body. At this time, a large area of ​​sputum is exposed to the air and it is easy to cause virus spread. In order to reduce the possibility of virus spread, medical staff will take the approach of repeatedly tightening the cup lid. However, repeatedly tightening the cup lid will also increase the contact time between the medical staff and the sputum cup. When collecting with a dropper, the sputum is spread flat on the bottom of the cup body, making it difficult to collect enough sputum for pathological testing, prompting medical staff to collect sputum for a long time, increasing the contact time with the sputum, and thereby increasing the risk of infection. Therefore, the present application provides a specimen collection device for a pathology department to meet the needs. Summary of the invention

[0015] Optionally, one end of a spiral spring is fixedly connected to the bottom edge of the turntable through a second connecting column, the spiral spring is movably sleeved on the outside of the rotating shaft, and the other end of the spiral spring is fixedly connected to the inner bottom wall of the circular sputum collecting groove through a first connecting column.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, a funnel that can be removed from the cup body is provided to facilitate the patient to spit sputum into the cup body, and a rubber pad is provided on the inner wall of the sleeve groove, so that the top outer wall of the funnel can be clamped and fixed on the outside of multiple arc blocks with the help of the elastic effect of the rubber pad, so as to facilitate the installation between the funnel and the cup body.

[0018] By setting the sampling piece, when the medical staff needs to collect and sample the sputum in the cup body, they only need to unscrew the cup cover once. Since the sampling tube is movably inserted in the funnel, its key bar slides in the movable channel, and at the same time cooperates with the setting of four sealing spring pieces, the dropper can separate and seal the inside of the sampling tube before it is inserted, thereby effectively preventing the sputum in the cup body from being exposed to the air over a large area after the cup cover is unscrewed, thereby effectively preventing the spread of the virus.

In this way, when sampling, the area of ​​sputum inside the cup body exposed to the air can be greatly reduced, thereby effectively preventing the possibility of the virus spreading and infecting easily due to excessive exposure area.

[0019] By setting up a sputum scraper, during the use of the above-mentioned sampling component, the medical staff will hold the dropper and insert it into the sampling tube, and use the force of the medical staff to push the dropper downward to synchronously cause the sampling tube to move downward in conjunction, and combine with the transmission column to enter the vertical channel, and cooperate with the spiral groove connected to the bottom of the vertical channel, so that the turntable fixed to the bottom end of the rotating cylinder rotates counterclockwise through the rotating shaft, and the volute spring will be rolled up and deformed under the setting of the first connecting column and the second connecting column, and at the same time, the turntable drives the arc-shaped scrapers fixed to multiple fixed blocks respectively to move along the inclined surface of the bottom wall of the cup body. The cup body is provided with a circular rotation, thereby effectively scraping off the sticky sputum on the inclined surface of the bottom wall of the cup body and collecting it in the circular sputum collecting groove, so that the conical suction part at the bottom end of the dropper can collect enough sputum for pathological testing, shortening the time for medical staff to collect sputum and reducing the contact time with sputum, thereby further reducing the risk of infection. After the sampling is completed, the medical staff releases the downward thrust on the test tube, so that under the reverse action of the vortex spring, the dropper clamped and fixed in the sampling tube by four sealing springs can be automatically ejected, thereby efficiently completing the sputum collection work.

[0039] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides a specimen collection device for a pathology department, comprising a cup body 1 and a cup cover 2. A plurality of arc blocks 21 arranged in a circular array are fixedly connected to the top of the cup body 1, and each arc block 21 is provided with a thread on its outer side. The cup cover 2 is threadedly connected to the top of the cup body 1 via the plurality of arc blocks 21. The inner bottom wall of the cup body 1 is an inverted cone structure, and a circular sputum collecting groove for collecting sputum is provided at the center of the inner bottom wall of the cup body 1; a funnel 3 is movably overlapped at the top opening of the cup body 1, and a sleeve groove 31 matching the shape of the arc block 21 is provided on the top peripheral wall of the funnel 3, and each The inner walls of the sleeve grooves 31 are provided with rubber pads, and the sleeve grooves 31 are used to be sleeved on the outer sides of the arc blocks 21. Combined with the setting of the rubber pads, the funnel 3 can be clamped on the outer sides of multiple arc blocks 21; it also includes a sampling piece 4 and a sputum scraper 5. The sampling piece 4 is used to facilitate the sampling of sputum by a dropper on the one hand, and to achieve active sealing inside the cup body 1 after sampling on the other hand. The sampling piece 4 is installed on the funnel 3; the sputum scraper 5 is used to scrape the sputum on the inclined surface of the inner bottom wall of the cup body 1 into the circular sputum collecting groove on the basis of using the sampling piece 4. The sputum scraper 5 is installed on the inner bottom of the cup body 1 and is connected to the sampling piece 4.

[0040] Among them, the rubber pad is attached Figure 2 As can be seen in the figure, the elasticity of the rubber pad can be used to clamp the outer side of the arc block 21.

[0041] like Figures 3 to 10 As shown, in order to reduce the area of ​​sputum exposed to the air when the sputum inside the cup body 1 is sampled with a dropper, the sampling component 4 is provided to include a sampling tube 41 movably inserted in the funnel 3, and two symmetrically distributed pinching blocks 42 are fixedly connected to the outer peripheral wall of the top end of the sampling tube 41, and the two pinching blocks 42 are used for the convenience of medical staff to hold them, and a key bar 43 is also fixedly connected to the outer wall of the sampling tube 41, and the key bar 43 is vertically arranged with the center line of the pinching block 42, and the inner wall of the bottom tube of the funnel 3 is provided with an active channel 431 for the lifting and lowering movement of the key bar 43, and the active channel 431 is adapted to the key bar 43, and the inner bottom wall of the active channel 431 is in a closed state, which is used to prevent the key bar 43 from continuing to move downward.

[0042] The bottom end of the sampling tube 41 extends out of the bottom pipe of the funnel 3, and is fixedly connected to L-shaped connecting rods 44 on all sides. The bottom ends of the four L-shaped connecting rods 44 are fixedly connected to the same support block 45. A conical hole 46 is opened at the center of the support block 45. The conical hole 46 is used for inserting the bottom end of the sampling dropper and extends out of the bottom of the support block 45. The four L-shaped connecting rods 44 are fixedly connected to a sealing spring 47 on one side wall facing the center of the bottom end of the sampling tube 41. The vertical cross-section of the sealing spring 47 is wavy. Structure, the top of the sealing spring piece 47 away from the center of the bottom end of the sampling tube 41 is fixed to the bottom end of the sampling tube 41, the cross-section of the sealing spring piece 47 is a quarter-circular structure, and each sealing spring piece 47 is provided with a clamping portion 48 at one end close to the center of the bottom end of the sampling tube 41. The cross-section of the clamping portion 48 is an arc-shaped structure, and the clamping portion 48 is distributed in an inclined state. A weakening groove 49 is provided at the connection between the top of the clamping portion 48 and the end of the sealing spring piece 47 away from the L-shaped connecting rod 44.

[0043] Among them, the setting of the two pinching blocks 42 can facilitate the medical staff to take out the sampling tube 41. Due to the closed state of the bottom end of the active channel 431, the sampling tube 41 moves up and drives the transmission column 51 to move upward, and the funnel 3 can be taken out from the cup body 1 simultaneously, so that the patient can spit sputum into the open cup body 1 for collection. The setting of the key bar 43 enables the sampling tube 41 to be inserted into the funnel 3, so that the position of the transmission column 51 after installation can be directly above the vertical channel 57, and it is convenient to promote the transmission column 51 to enter the vertical channel 57 when it moves down. The conical hole 46 on the support block 45, its conical hole 4 The top diameter of 6 is larger than the bottom diameter in order to match the bottom shape design of the dropper adopted in the prior art. The shape of the dropper can be found on Baidu. The four sealing spring pieces 47 form a circular structure. On the one hand, the partition and seal of the inside of the sampling tube 41 can be performed before the dropper is inserted, thereby effectively preventing the sputum inside the cup body 1 from spreading into the air over a large area. In addition, when the dropper is inserted into the center of the four sealing spring pieces 47, the clamping part 48 cooperates with the weakened groove 49 to facilitate the clamping and fixing of the outer side of the dropper, thereby effectively preventing the problem of medical staff shaking the dropper when taking samples and affecting the sampling efficiency.

[0044] like Figures 3 to 10As shown, in order to be able to scrape and concentrate the viscous sputum on the inclined surface of the inner bottom wall of the cup body 1 on the basis of the use of the above-mentioned sampling member 4, the sputum scraper 5 is provided, which includes a transmission column 51 located directly below the active channel and fixedly connected to the outer wall of the sampling tube. The transmission column 51 is located directly below the key bar 43. The inner bottom wall of the circular sputum collecting groove is rotatably connected with a turntable 53 through a rotating shaft 54. A rotating cylinder 52 is fixedly connected to the top of the turntable 53. A plurality of sputum inlet channels 55 arranged in a circular array are provided on the outer peripheral wall of the bottom end of the rotating cylinder 52. A vertical channel 57 is provided on the inner wall of the rotating cylinder 52 near the top of the rotating cylinder 52. The top opening of the vertical channel 57 is connected to the outside. The transmission column 51 can be inserted into the vertical channel 57 from the top opening of the vertical channel 57. The bottom end is connected with a spiral groove 56, which is opened on the inner wall of the rotating cylinder 52. The widths of the spiral groove 56 and the vertical channel 57 match the diameter of the transmission column 51. A plurality of irregularly shaped lightweight grooves 58 are provided above the plurality of sputum inlet channels 55 and are opened on the rotating cylinder 52. A plurality of fixed blocks 59 arranged in a circular array are fixedly connected to the top of the turntable 53. An arc scraper 510 is fixedly connected to one side wall opposite to the other of the plurality of fixed blocks 59. The bottom ends of the arc scrapers 510 are all in contact with the inner bottom wall of the cup body 1. One end of a volute spring 511 is fixedly connected to the bottom edge of the turntable 53 through a second connecting column 513. The volute spring 511 is movably sleeved on the outer side of the rotating shaft 54. The other end of the volute spring 511 is fixedly connected to the inner bottom wall of the circular sputum collecting groove through a first connecting column 512.

[0045] Among them, when the patient initially spits sputum into the cup body 1, part of the sputum will fall into the rotating cylinder 52. The opening of the lightweight groove 58, on the one hand, reduces the weight of the rotating cylinder 52, and on the other hand, during the rotation, the sputum on the inner wall of the rotating cylinder 52 is rotated and thrown out. The shape design of the arc scraper 510 makes it easier to scrape the sputum on the inclined surface of the inner bottom wall of the cup body 1, so as to better concentrate it into the circular sputum collecting groove, so as to facilitate rapid suction by the dropper. The top and bottom ends of the spiral spring 511 are respectively fitted with the bottom end of the turntable 53 and the inner bottom wall of the circular sputum collecting groove, the top end of the first connecting column 512 is fitted with the bottom end of the turntable 53, and the bottom end of the second connecting column 513 is fitted with the inner bottom wall of the circular sputum collecting groove.

[0046] The working principle of the technical solution provided by the present invention is as follows:

[0047] The first step: the medical staff unscrews the cup cover 2. Through the setting of the two pinching blocks 42, the medical staff can conveniently take out the sampling tube 41. At the same time, due to the closed state of the bottom end of the movable channel 431, the medical staff can pull the sampling tube 41 upward and drive the transmission column 51 to move upward, and can simultaneously take out the funnel 3 from the cup body 1. After that, it is convenient for the patient to spit sputum into the cup body 1. After the patient spits sputum into the cup body 1, the medical staff holds the two pinching blocks 42 and reinstalls the funnel 3 inside the cup body 1, and combines with the rubber pad set on the inner wall of the sleeve groove 31, so that the top outer peripheral wall of the funnel 3 can be clamped and fixed to the outside of the multiple arc blocks 21 with the help of the elastic effect of the rubber pad, so as to facilitate the installation between the funnel 3 and the cup body 1. After tightening the cup cover 2, the cup body 1 with sputum collected is sent to the pathology department for testing.

[0048] Step 2: After the funnel 3 is installed in the cup body 1, its transmission column 51 will enter the vertical channel 57. During the pathology test, the laboratory personnel unscrew the cup cover 2 and collect samples of sputum in the cup body 1. The cup cover 2 can be unscrewed once. Since the sampling tube 41 is movably inserted in the funnel 3, its key bar 43 slides in the movable channel 431, and at the same time cooperates with the setting of four sealing spring pieces 47, so that the dropper can separate and seal the inside of the sampling tube 41 before insertion, thereby effectively avoiding that the sputum in the cup body 1 is exposed to the air over a large area after the cup cover 2 is unscrewed, thereby effectively preventing the spread of the virus. In addition, in the subsequent When it is necessary to collect sputum through a dropper, the medical staff can pinch the air bag on the top of the dropper by hand, insert the dropper into the sampling tube 41, and at the same time insert the conical suction part at the bottom end of the dropper into the center of the four sealing spring pieces 47, so that the outer wall of the dropper will squeeze the four clamping parts 48 to deform through the weakened grooves 49 respectively, and clamp and fix the dropper, and continue to push the dropper downward for sampling until the conical suction part at the bottom end of the dropper is inserted into the conical hole 46 opened in the center of the support block 45. In this way, when sampling, the area of ​​sputum inside the cup body 1 exposed to the air can be greatly reduced, thereby effectively preventing the exposure area from being too large and causing the virus to spread and infect easily.

[0049] Step 3: During the use of the sampling member 4, the medical staff will insert the dropper into the sampling tube 41, and use the force of the dropper to push the sampling tube 41 downward to synchronously move the sampling tube 41 downward, and the transmission column 51 enters the vertical channel 57, and cooperates with the spiral groove 56 connected to the bottom of the vertical channel 57, so that the transmission column 51 will continue to enter the spiral groove 56, and promote the rotating cylinder 52 and the turntable 53 fixed at the bottom to rotate counterclockwise through the rotating shaft 54, but the volute spring 511 will be rolled up and deformed under the setting of the first connecting column 512 and the second connecting column 513, and the turntable 53 drives a plurality of fixed blocks 59 at the same time. The arc scrapers 510 respectively fixedly connected rotate in a circle along the inclined surface of the inner bottom wall of the cup body 1, thereby effectively scraping the viscous sputum on the inclined surface of the inner bottom wall of the cup body 1 and concentrating it in the circular sputum collecting groove, so that the conical suction part at the bottom end of the dropper can collect sufficient sputum for pathological testing, shortening the time for medical staff to collect sputum, and reducing the contact time with sputum, thereby further reducing the risk of infection. After the sampling is completed, the medical staff releases the downward thrust on the test tube, so that under the reverse action of the vortex spring 511, the dropper clamped and fixed in the sampling tube 41 by four sealing springs 47 can be automatically pushed out, thereby efficiently completing the sputum collection work.
