Abstract

The present invention provides a specimen collection device for the pathology department, belonging to the technical field of medical devices. It includes a cup body and a cup cover. A plurality of arc-shaped blocks arranged in a circular array are fixedly connected to the top end of the cup body. Threads are provided on the outer side of each arc-shaped block. The cup cover is threadedly connected to the top of the cup body through the plurality of arc-shaped blocks. The inner bottom wall of the cup body is of an inverted conical structure, and a circular sputum collection groove for concentrating sputum is opened at the center of the inner bottom wall of the cup body. By setting a sampling member, when medical staff need to collect and sample the sputum inside the cup body, they only need to unscrew the cup cover once. Since the sampling tube is movably inserted into the funnel, its key strip slides in the movable channel, and at the same time, with the setting of four sealing elastic pieces, the inside of the sampling tube can be partitioned and sealed before the dropper is inserted, effectively avoiding the large-area exposure of the sputum inside the cup body to the air after the cup cover is unscrewed, and thus effectively preventing the spread of the virus.

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

[0004] The technical problem to be solved by the present invention is to provide a specimen collection device for the pathology department, so as to solve the problem that the top of the existing cup body is open for a long time, so that sputum is exposed to the air, increasing the risk of virus spread; even if the cup cover is repeatedly tightened, the contact time between medical staff and the sputum cup cannot be effectively shortened; during the dropper collection process, sputum is usually deposited at the bottom of the cup, making it difficult to collect enough samples for testing. During the long collection process, the contact time of medical staff with sputum is increased, further increasing the risk of infection.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A specimen collection device for the pathology department, comprising a cup body and a cup cover. A plurality of arc-shaped blocks arranged in a circular array are fixedly connected to the top end of the cup body. Threads are provided on the outer side of each arc-shaped block. The cup cover is threadedly connected to the top of the cup body through the plurality of arc-shaped blocks. The inner bottom wall of the cup body is in an inverted conical structure, and a circular sputum collection groove for concentrating sputum is opened at the center of the inner bottom wall of the cup body; a funnel is movably lapped at the top opening of the cup body. Socket grooves adapted to the shapes of the arc-shaped blocks are opened on the outer peripheral wall of the top of the funnel. Rubber pads are provided on the inner walls of each socket groove. The socket grooves are all used for sleeving on the outer sides of the arc-shaped blocks, and in combination with the arrangement of the rubber pads, the funnel can be clamped on the outer sides of the plurality of arc-shaped blocks; it further includes a sampling member and a sputum scraping member. The sampling member is installed on the funnel; on the basis of using the sampling member, the sputum scraping member is used to scrape the sputum on the inclined surface of the inner bottom wall of the cup body into the circular sputum collection groove. The sputum scraping member is installed at the inner bottom of the cup body and is connected to the sampling member.

[0007] Optionally, the sampling member includes a sampling tube movably inserted in the funnel. Two symmetrically distributed pinch blocks are fixedly connected to the outer peripheral wall of the top end of the sampling tube.

[0008] Optionally, a key strip is further fixedly connected to the outer wall of the sampling tube. The key strip is perpendicular to the center line of the pinch block. An activity channel for the lifting and lowering movement of the key strip is opened on the inner wall of the bottom tube of the funnel. The activity channel is adapted to the key strip, and the inner bottom wall of the activity channel is in a closed state.

[0009] Optionally, L-shaped connecting rods are fixedly connected to the peripheries of the bottom ends of the sampling tube. The same supporting block is fixedly connected between the bottom ends of the four L-shaped connecting rods. A conical hole is opened at the center of the supporting block. The bottom end of the sampling dropper is inserted into the conical hole and extends out of the bottom of the supporting block.

[0010] Optionally, sealing elastic sheets are fixedly connected to the side walls of the four L-shaped connecting rods facing the center of the bottom end of the sampling tube. The vertical cross-sections of the sealing elastic sheets are all in a wavy structure. One end of the sealing elastic sheet far from the center of the bottom end of the sampling tube is fixedly connected to the bottom end of the sampling tube. The cross-section of the sealing elastic sheet is in a quarter-circle shape structure.

[0011] Optionally, a clamping portion is provided at one end of each sealing elastic sheet close to the center of the bottom end of the sampling tube. The cross-section of the clamping portion is in an arc shape structure. The clamping portion is obliquely distributed. A weakening groove is opened at the connection between the top end of the clamping portion and the end of the sealing elastic sheet far from the L-shaped connecting rod.

[0012] Optionally, the sputum scraping member includes a transmission column fixedly connected to the outer wall of the sampling tube. The transmission column is located directly below the key strip.

[0013] Optionally, the inner bottom wall of the circular sputum collection groove is rotatably connected to a turntable through a rotating shaft. A rotating cylinder is fixedly connected to the top end of the turntable. A plurality of sputum inlet channels arranged in an annular array are formed on the outer peripheral wall of the bottom end of the rotating cylinder. A vertical channel is formed in the inner wall of the rotating cylinder near the top end of the rotating cylinder. The top opening of the vertical channel communicates outward. The transmission column can be inserted into the vertical channel from the top opening of the vertical channel. The bottom end of the vertical channel communicates with a spiral groove. The spiral groove is formed in the inner wall of the rotating cylinder. The widths of the spiral groove and the vertical channel are both equal to the diameter of the transmission column. Above the plurality of sputum inlet channels, a plurality of irregularly shaped lightening grooves are formed on the rotating cylinder.

[0014] Optionally, a plurality of fixing blocks arranged in an annular array are fixedly connected to the top end of the turntable. Arc-shaped scraping plates are fixedly connected to the outer side walls of the plurality of fixing blocks facing away from each other. The bottom ends of the arc-shaped scraping plates are all attached to the inner bottom wall of the cup body.

[0015] Optionally, one end of a scroll spring is fixedly connected to the edge of the bottom end of the turntable through a second connecting column. The scroll spring is movably sleeved on the outer side of the rotating shaft. The other end of the scroll spring is fixedly connected to the inner bottom wall of the circular sputum collection 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 solution, by providing a funnel that can be taken out of the cup body, it is convenient for the patient to spit phlegm into the cup body. Combined with the rubber pad provided on the inner wall of the socket groove, the outer peripheral wall of the top of the funnel can be clamped and fixed on the outer side of the plurality of arc-shaped blocks by the elastic action 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 addition, when the sputum needs to be collected through the dropper later, the medical staff can pinch the top of the dropper by hand to The air bag at the bottom of the dropper is removed, and the dropper is inserted into the sampling tube, and at the same time, the tapered suction part at the bottom end of the dropper is inserted into the center of the four sealing spring pieces, so that the outer wall of the dropper will squeeze the four clamping parts to deform through the weakened grooves respectively, and the dropper is clamped and fixed, and the tapered suction part at the bottom end of the dropper is inserted into the conical hole opened in the center of the support block, and the dropper is continued to be pushed downward for sampling. 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] As Figure 1 and Figure 2As shown in the figure, an embodiment of the present invention provides a specimen collection device for the pathology department, including a cup body 1 and a cup cover 2. A plurality of arc-shaped blocks 21 arranged in a circular array are fixedly connected to the top end of the cup body 1. Threads are provided on the outer side of each arc-shaped block 21. The cup cover 2 is threadedly connected to the top of the cup body 1 through the plurality of arc-shaped blocks 21. The inner bottom wall of the cup body 1 is of an inverted conical structure, and a circular sputum collection groove for concentrating sputum is opened at the center of the inner bottom wall of the cup body 1. A funnel 3 is movably lapped at the top opening of the cup body 1. Sleeve grooves 31 adapted to the shape of the arc-shaped blocks 21 are opened on the outer peripheral wall of the top of the funnel 3. Rubber pads are provided on the inner walls of each sleeve groove 31. The sleeve grooves 31 are all used to sleeved on the outer sides of the arc-shaped blocks 21. And with the setting of the rubber pads, the funnel 3 can be clamped on the outer sides of the plurality of arc-shaped blocks 21. It further includes a sampling member 4 and a sputum scraping member 5. On the one hand, the sampling member 4 is used to facilitate the sampling of sputum by a dropper, and on the other hand, it is used to actively seal the inside of the cup body 1 after sampling. The sampling member 4 is installed on the funnel 3. On the basis of using the sampling member 4, the sputum scraping member 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 collection groove. The sputum scraping member 5 is installed at the inner bottom of the cup body 1 and is connected to the sampling member 4.

[0040] Among them, the rubber pad can be clamped on the outer side of the arc-shaped block 21 by means of its elasticity as can be seen in the appendix. Figure 2 As shown, it can be clamped on the outer side of the arc-shaped block 21 by means of the elasticity of the rubber pad.

[0041] Such as Figures 3 to 10 As shown, in order to reduce the area of sputum exposed to the air when sampling sputum inside the cup body 1 with a dropper, the sampling member 4 is provided to include a sampling tube 41 movably inserted in the funnel 3. Two symmetrically distributed pinch blocks 42 are fixedly connected to the outer peripheral wall of the top end of the sampling tube 41. The two pinch blocks 42 are used to facilitate the medical staff to hold. A key strip 43 is also fixedly connected to the outer wall of the sampling tube 41. The key strip 43 is perpendicular to the center line of the pinch blocks 42. An activity channel 431 for the lifting movement of the key strip 43 is opened on the inner wall of the bottom tube of the funnel 3. The activity channel 431 is adapted to the key strip 43. The inner bottom wall of the activity channel 431 is in a closed state to prevent the key strip 43 from moving down further.

[0042] The bottom end of the sampling tube 41 extends outside the bottom pipe of the funnel 3, and L-shaped connecting rods 44 are fixedly connected to the periphery of the outside. A same support block 45 is fixedly connected between the bottom ends of the four L-shaped connecting rods 44. A conical hole 46 is formed at the center of the support block 45. The conical hole 46 is used for the bottom end of the sampling dropper to be inserted and extend out of the bottom of the support block 45. On one side wall of the four L-shaped connecting rods 44 facing the center of the bottom end of the sampling tube 41, sealing elastic sheets 47 are fixedly connected. The vertical cross-sections of the sealing elastic sheets 47 are all in a wavy structure. The tops of the sealing elastic sheets 47 far from the center of the bottom end of the sampling tube 41 are fixedly connected to the bottom end of the sampling tube 41. The cross-section of the sealing elastic sheet 47 is in a quarter-circle shape structure. A clamping portion 48 is provided at one end of each sealing elastic sheet 47 close to the center of the bottom end of the sampling tube 41. The cross-section of the clamping portion 48 is in an arc shape structure. The clamping portions 48 are distributed obliquely. A weakening groove 49 is formed at the connection between the top end of the clamping portion 48 and the end of the sealing elastic sheet 47 far from the L-shaped connecting rod 44.

[0043] Among them, the setting of the two pinch blocks 42 can facilitate the medical staff to take out the sampling tube 41. At the same time, due to the closed state of the bottom end of the moving channel 431, combined with the upward movement of the sampling tube 41 and the driving of the transmission column 51 to move upward, the funnel 3 can be taken out of the cup body 1 synchronously, so that the patient can spit and collect sputum into the open cup body 1. The setting of the key strip 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 can facilitate the transmission column 51 to move down into the vertical channel 57. The conical hole 46 on the support block 45 has a larger top diameter than the bottom diameter, which is designed to match the bottom shape of the dropper used in the prior art. The shape of the dropper can be found on Baidu. The four sealing elastic sheets 47 enclose a circular structure. On the one hand, it can cut off and seal the inside of the sampling tube 41 before the dropper is inserted, thus effectively preventing the sputum inside the cup body 1 from spreading to the air on a large scale. In addition, when the dropper is inserted into the center of the four sealing elastic sheets 47, with the cooperation of the weakening groove 49 and the clamping portion 48, it can facilitate the clamping and fixing of the outside of the dropper, and further effectively avoid the problem that the medical staff's hand-held dropper shakes during sampling, which affects the sampling efficiency.

[0044] Such as 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] Step 1: The medical staff unscrew the cup cover 2. With the arrangement of the two pinch blocks 42, it is convenient for the medical staff to take out the sampling tube 41. At the same time, due to the closed state of the bottom end of the moving channel 431, with the cooperation of the medical staff holding and pulling the sampling tube 41 upward to drive the transmission column 51 to move upward, the funnel 3 can be taken out of the cup body 1 synchronously. After that, it is convenient for the patient to spit phlegm into the cup body 1. After the patient spits phlegm into the cup body 1 and it is collected, the medical staff holds the two pinch blocks 42 and reinstalls the funnel 3 inside the cup body 1. Combining with the rubber pad arranged on the inner wall of the socket 31, the outer peripheral wall of the top of the funnel 3 can be clamped and fixed outside the plurality of arc-shaped blocks 21 by the elastic action of the rubber pad, so as to facilitate the installation between the funnel 3 and the cup body 1. After screwing the cup cover 2 tightly, the cup body 1 for collecting phlegm is sent to the pathology department for testing.

[0048] Step 2: After the above-mentioned funnel 3 is installed in the cup body 1, its transmission column 51 will enter the vertical channel 57. During the testing process in the pathology department, when the testing personnel unscrew the cup cover 2 and collect and sample the phlegm inside the cup body 1, it is only necessary to unscrew the cup cover 2 once. Since the sampling tube 41 is movably inserted into the funnel 3, its key strip 43 slides in the moving channel 431, and at the same time, with the arrangement of the four sealing elastic pieces 47, before the dropper is inserted, the inside of the sampling tube 41 can be partitioned and sealed, so as to effectively prevent the phlegm inside the cup body 1 from being largely exposed to the air after the cup cover 2 is unscrewed, and thus effectively prevent the spread of the virus. In addition, when it is necessary to collect phlegm through the dropper later, the medical staff can squeeze the air bag at the top of the dropper by hand and insert the dropper into the sampling tube 41. At the same time, the conical suction part at the bottom end of the dropper is inserted into the center of the four sealing elastic pieces 47, so that the outer wall of the dropper will squeeze the four clamping parts 48 to deform through the weakening grooves 49 respectively, and realize the clamping and fixing of the dropper. And until the conical suction part at the bottom end of the dropper is inserted into the conical hole 46 opened at the center of the support block 45 and then continue to push the dropper downward for sampling, in this way, when sampling, the area of the phlegm inside the cup body 1 exposed to the air can be greatly reduced, so as to effectively prevent the virus from being easily spread and infected due to the too large exposed area.

[0049] Step 3: During the use of the above-mentioned sampling piece 4, after the medical staff inserts the dropper into the sampling tube 41 by hand, and with the force of the medical staff pushing the dropper downward by hand, the sampling tube 41 is synchronously driven to move downward. In combination with the transmission column 51 entering the vertical channel 57, and cooperating with the spiral groove 56 communicated with the bottom of the vertical channel 57, the transmission column 51 will continue to enter the spiral groove 56, and the rotating cylinder 52 together with the turntable 53 fixedly connected to the bottom end will rotate counterclockwise through the rotating shaft 54. However, the scroll spring 511 will be wound and deformed under the arrangement of the first connecting column 512 and the second connecting column 513. At the same time, the turntable 53 drives the arc-shaped scrapers 510 fixedly connected to the respective fixing blocks 59 to rotate annularly along the inclined surface of the inner bottom wall of the cup body 1, so as to effectively scrape off the viscous sputum on the inclined surface of the inner bottom wall of the cup body 1 and concentrate it into the circular sputum collection groove, so as to facilitate the bottom tapered suction part of the dropper to collect a sufficient amount of sputum for pathological examination, shorten the time for medical staff to collect sputum, and reduce the contact time with sputum, thereby further reducing the risk of infection. After the sampling is completed, the medical staff releases the downward pushing force on the test tube. Thus, under the reverse action of the scroll spring 511, the dropper clamped and fixed inside the sampling tube 41 by the four sealing elastic pieces 47 can be automatically ejected, so as to efficiently complete the sputum collection work.
