TECHNICAL FIELD

[0001] The present application relates to the technical field of sampling collection devices, in particular to a yak semen collection device for yak semen preservation. BACKGROUND

[0002] In the process of yak semen preservation, a yak semen collection device is needed. The existing related device has the following problems: the top notch of the sampling test tube is prone to cracking and breaking, affecting the normal use of the device and the preservation of the semen. When the sampled yak semen is taken out of the sampling test tube, the semen is prone to adhere to the inner wall of the sampling test tube, causing wall hanging phenomenon, which makes it inconvenient to take out the semen and causes waste. After cracks appear at the bottom of the sampling test tube, the yak semen inside is prone to leak out, affecting the preservation effect of the semen.

[0003] In addition, it is inconvenient to temporarily sub-sample the yak semen collected in the sampling test tube. It is difficult to protect the sampling test tube while clearly displaying the information of the yak semen collected in the sampling test tube. SUMMARY

[0004] The purpose of the present application is to provide a yak semen collection device for yak semen preservation to solve the problems raised in the background.

[0007] Preferably, a plurality of anti-slip groove is provided on the outer wall of the first sealing cover. A sheath is fixed to the bottom surface of the top plate of the first sealing cover. The sheath is sleeved on the top end of the extraction handle. A silica gel plug piece is fixed to the bottom surface of the top plate of the first sealing cover. The silica gel plug piece is an inverted trapezoidal plate, and the silica gel plug piece is inserted into the top opening of the sampling test tube, and the top surface diameter of the silica gel plug piece is larger than the top opening diameter of the sampling test tube.

[0008] Preferably, an annular fitting groove is provided on the side wall of the scraper. A circular rubber scraping ring with an isosceles trapezoidal cross-section is sleeved and fixed inside the fitting groove. The outer diameter of the rubber scraping ring is larger than the top surface diameter of the scraper. The rubber scraping ring is clamped between the inner wall of the sampling test tube and the scraper to generate elastic deformation.

[0009] Preferably, the rubber cushion block has a hemispherical structure, and the rubber cushion block fills the bottom of the sampling test tube.

[0010] Preferably, a storage groove for storing the sub-sampling box is provided on the top surface of the first sealing cover. A second sealing cover is sleeved and screwed on the top end of the sub-sampling box. The second sealing cover is inserted into the storage groove. An annular card slot is provided on the side wall of the second sealing cover. A rubber card ring sleeved inside the card slot is fixed on the side wall of the storage groove.

[0011] Preferably, a picking groove is provided on the top surface of the second sealing cover. The picking groove is a circular groove with a "convex" shaped break. The distance from the bottom surface of the sub-sampling box to the top surface of the second sealing cover is less than the height of the storage groove.

[0012] Preferably, an internal thread is provided on the inner wall at the top end of the transparent plastic protective sleeve, and the internal thread is in threaded connection with the external thread provided on the outer wall of the connecting sleeve.

[0013] Preferably, a reserved groove for storing the identification strip is provided on the inner wall of the transparent plastic protective sleeve. The reserved groove is an annular groove. Rubber retaining rings are fixed on both the top surface and the bottom surface of the reserved groove. The identification strip is located between the outer ring surface of the rubber retaining ring and the outer ring surface of the reserved groove.

[0014] Preferably, a rubber anti-slip sleeve is sleeved and fixed on the outer wall at the top end of the transparent plastic protective sleeve.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The yak semen collection device for yak semen preservation proposed by the present invention, by sleeving and fixedly connecting a connecting sleeve at the top end of the sampling test tube, the connecting sleeve not only prevents the top slot of the sampling test tube from cracking and breaking, but also serves as a connecting structure for installing the sealing cover on the top of the sampling test tube, prolongs the service life of the sampling test tube, and ensures the semen preservation environment.

[0016] To address the issue of semen adhering to the sample tube walls: A scraper is inserted into the bottom of the sampling tube, with a rubber scraper ring embedded in its side wall. Squeezing the extraction handle moves the scraper along the inner wall of the tube, scraping off and pushing the adhering yak semen upwards, facilitating extraction into the slot at the top of the tube. This improves the efficiency and integrity of semen extraction. Simultaneously, a protective sleeve is installed at the bottom of the sealing cap. After the scraper is placed at the top of the tube and the sealing cap is installed, the sleeve covers the top of the extraction handle, preventing semen from adhering to the handle tip and facilitating subsequent extraction.

[0017] To prevent leakage at the bottom: A rubber pad is fixed to the bottom of the scraper. After the rubber pad falls into the bottom of the sampling tube, it covers the cracks on the surface of the sampling tube and fills the space from the bottom of the scraper to the bottom of the sampling tube. After being squeezed by the scraper, it adheres to the inner wall of the bottom of the sampling tube. Even if cracks appear at the bottom of the sampling tube, the yak semen inside the sampling tube will not leak out from the cracks, ensuring the safety of semen preservation.

[0018] For convenient temporary sampling: The top of the sealing cap is fitted with a sampling box. By holding your finger at the top edge of the sampling groove, you can pull the sealing cap and the sampling box out of the storage slot. Unscrew the sealing cap to remove it, pour a portion of the yak semen collected inside the sampling tube into the sampling box, and then screw the sampling box back on to complete the temporary small-scale sampling. The operation is convenient and quick. When the sampling box is not in use and is stored in the storage slot, the rubber retaining ring is fitted in the slot to prevent the sampling box from falling out of the storage slot.

[0019] Balancing protection and information display: A transparent plastic protective sleeve is fitted over the bottom of the sampling tube, with its top screwed onto the bottom of the connecting sleeve, providing protection for the sampling tube. An identification strip, pre-inserted with information about the yak semen collected inside the sampling tube, is inserted into a pre-drilled groove. The transparent plastic protective sleeve is then slipped over the top of the sampling tube and screwed onto the bottom of the connecting sleeve. While protecting the sampling tube, the transparent plastic protective sleeve simultaneously displays the yak semen information between the sleeve and the tube, facilitating user access to semen-related information. The connecting sleeve not only serves as a protective structure for the top groove of the sampling tube but also allows for the connection and installation of the sealing cap and the transparent plastic protective sleeve, improving the overall integrity and practicality of the device.

[0022] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 9 This invention provides a technical solution: a yak semen collection device for preserving yak semen, comprising a sampling tube 1, a connecting sleeve 2 fixedly fitted to the top of the sampling tube 1, and a sealing cap 3 screwed onto the top of the connecting sleeve 2. The connecting sleeve 2 is a cylindrical tube with an "L"-shaped cross-section, and its top surface overlaps the top surface of the sampling tube 1. The inner diameter of the top ring of the connecting sleeve 2 is equal to the inner diameter of the top ring of the sampling tube 1. The outer wall of the connecting sleeve 2 has external threads, and the inner wall of the sealing cap 3 has internal threads, which are connected in a mating manner. The outer wall of the sealing cap 3 has multiple anti-slip grooves 301. The sampled yak semen is stored in the sampling tube 1, and then the sealing cap 3 is screwed on to seal the top opening of the sampling tube 1. The addition of the connecting sleeve 2 not only prevents the top opening of the sampling tube 1 from cracking and breaking, but also serves as a connecting structure for the sealing cap 3 installed on the top of the sampling tube 1.

[0024] To avoid the phenomenon of yak semen adhering to the walls of the sampled tube when it is removed from sampling tube 1, the following was proposed: A scraper 4 is inserted into the bottom of the sampling tube 1. A lifting handle 404 is fixed to the top surface of the scraper 4. The lifting handle 404 drives the scraper 4 to move along the inner wall of the sampling tube 1. An annular groove 401 is provided on the side wall of the scraper 4. A circular rubber scraper ring 402 with an isosceles trapezoidal cross-section is fitted and fixed inside the groove 401. The outer diameter of the rubber scraper ring 402 is larger than the top diameter of the scraper 4. The rubber scraper ring 402 is clamped in the sampling tube 1. Elastic deformation occurs between the inner wall of the sample tube 1 and the scraper 4; a protective sleeve 304 is fixed on the bottom surface of the top plate of the sealing cap 3, and the protective sleeve 304 is fitted on the top of the extraction handle 404. A silicone plug 305 is fixed on the bottom surface of the top plate of the sealing cap 3. The silicone plug 305 is an inverted frustum plate. The silicone plug 305 is inserted into the top opening of the sampling tube 1, and the top diameter of the silicone plug 305 is larger than the top opening diameter of the sampling tube 1.

[0025] Squeeze the top of the extraction handle 404 and pull it upwards to move the scraper 4 into the sampling tube 1. At this time, the scraper 4 and the rubber scraper ring 402 scrape off the yak semen adhering to the inner wall of the sampling tube 1 and push it upwards, finally pushing the yak semen into the top slot of the sampling tube 1 for removal. The reason for installing the protective sleeve 304 at the bottom of the sealing cap 3 is that after the scraper 4 falls into the top of the sampling tube 1 and the sealing cap 3 is installed on the top of the sampling tube 1, the protective sleeve 304 covers the top of the extraction handle 404 to prevent the yak semen from adhering to the top of the extraction handle 404, making it easier to squeeze the extraction handle 404.

[0026] To prevent the yak semen inside the sampling tube 1 from leaking out after a crack appears at the bottom, the following proposed solution is proposed: a rubber pad 403 is fixed to the bottom of the scraper 4. After the rubber pad 403 falls into the bottom of the sampling tube 1, it covers the crack on the surface of the sampling tube 1. The rubber pad 403 has a hemispherical structure and fills the bottom of the sampling tube 1. The rubber pad 403 fills the space from the bottom of the scraper 4 to the bottom of the sampling tube 1, and after being squeezed by the scraper 4, the rubber pad 403 adheres to the inner wall of the bottom of the sampling tube 1. Even if a crack appears at the bottom of the sampling tube 1, the yak semen inside the sampling tube 1 will not leak out from the crack due to the coverage of the rubber pad 403.

[0027] To facilitate temporary, small-scale sampling of yak semen collected inside test tube 1, the following approach was proposed: The top of the first sealing cover 3 is fitted with a sample dividing box 5, and the sample dividing box 5 is used to separately pack the yak semen samples collected inside the sampling test tube 1; a storage groove 302 for storing the sample dividing box 5 is provided on the top surface of the first sealing cover 3. The top end of the sample dividing box 5 is sleeved and screwed with a second sealing cover 501. The second sealing cover 501 is inserted into the storage groove 302. An annular clamping groove 503 is provided on the side wall of the second sealing cover 501, and a rubber clamping ring 303 sleeved inside the clamping groove 503 is fixed on the side wall of the storage groove 302; a picking groove 502 is provided on the top surface of the second sealing cover 501. The picking groove 502 is a circular groove with a "convex" shaped break. The distance from the bottom surface of the sample dividing box 5 to the top surface of the second sealing cover 501 is less than the height of the storage groove 302.

[0028] Put a finger on the top edge of the picking groove 502, pull out the second sealing cover 501 together with the sample dividing box 5 from the storage groove 302, unscrew and remove the second sealing cover 501 from the top of the sample dividing box 5, pour a part of the yak semen collected inside the sampling test tube 1 into the sample dividing box 5, and then screw the second sealing cover 501 back to seal the sample dividing box 5; when the sample dividing box 5 is not in use and is stored in the storage groove 302, since the rubber clamping ring 303 is sleeved in the clamping groove 503, the sample dividing box 5 is prevented from falling off the storage groove 302.

[0029] In order to protect the sampling test tube 1 and at the same time display the information of the yak semen collected inside the sampling test tube 1, the following is proposed: A transparent plastic protective sleeve 6 is sleeved at the bottom of the sampling test tube 1. The top end of the transparent plastic protective sleeve 6 is sleeved and screwed at the bottom end of the connecting sleeve 2. The top end of the transparent plastic protective sleeve 6 has internal threads on the inner wall, and the internal threads are in fit connection with the external threads provided on the outer wall of the connecting sleeve 2. An identification strip 602 is embedded inside the transparent plastic protective sleeve 6; a reserved groove 601 for storing the identification strip 602 is provided on the inner wall of the transparent plastic protective sleeve 6. The reserved groove 601 is an annular groove. Rubber retaining rings 603 are fixed on both the top surface and the bottom surface of the reserved groove 601. The identification strip 602 is located between the outer ring surface of the rubber retaining ring 603 and the outer ring surface of the reserved groove 601; a rubber anti-slip sleeve 604 is sleeved and fixed on the outer wall of the top end of the transparent plastic protective sleeve 6.

[0030] 预先将标注有采样试管1内部收集的牦牛精液信息的标识条602塞入预留槽601中,然后将透明塑料防护套6从采样试管1的顶部套入,并旋拧透明塑料防护套6套设螺接在连接套2底部,透明塑料防护套6对采样试管1防护为了实现对采样试管1防护的同时展示采样试管1内部收集牦牛精液的信息,提出了:同时,标识条602处于透明塑料防护套6和采样试管1之间展示牦牛精液的标注信息,连接套2不仅作为采样试管1顶部槽口的防护结构,并且同时满足密封盖一3和透明塑料防护套6的安装连接。

[0031] Usage method of the yak semen collection device: Insert the label 602, which indicates the yak semen collected inside the sampling tube 1, into the pre-reserved groove 601, ensuring that the label 602 is positioned between the outer ring surface of the rubber retaining ring 603 and the outer ring surface of the pre-reserved groove 601. Slide the transparent plastic protective sleeve 6 over the top of the sampling tube 1 and slowly move it downwards to the bottom of the connecting sleeve 2. Twist the transparent plastic protective sleeve 6 until its inner thread on the top wall mates with the outer thread on the outer wall of the connecting sleeve 2, ensuring a tight connection. The rubber anti-slip sleeve 604 on the outer wall of the top of the transparent plastic protective sleeve 6 facilitates gripping and operation.

[0032] Yak semen is collected using a suitable method and stored in a sampling tube 1 with a transparent plastic protective sleeve 6 already installed. The sealing cap 3 is screwed onto the connecting sleeve 2, ensuring the internal and external threads engage until the sealing cap 3 tightly seals the top opening of the sampling tube 1. At this point, a silicone stopper 305 is inserted into the top opening of the sampling tube 1. Since the top diameter of the silicone stopper 305 is larger than the top opening diameter of the sampling tube 1, a tight seal is ensured. A protective sleeve 304 is fitted over the top of the extraction handle 404 to prevent yak semen from adhering to the top of the extraction handle 404.

[0033] When retrieving yak semen, pinch the top of the extraction handle 404 and slowly pull it upwards, causing the scraper 4 to move upwards along the inner wall of the sampling tube 1. During the movement of the scraper 4, the rubber scraper ring 402, clamped between the inner wall of the sampling tube 1 and the scraper 4, undergoes elastic deformation, scraping off and pushing upwards the yak semen adhering to the inner wall of the sampling tube 1. Continue pulling the scraper 4 upwards until the yak semen is pushed into the top slot of the sampling tube 1, from which it can then be removed.

[0034] When a crack appears at the bottom of sampling tube 1, a rubber pad 403, which is hemispherical in shape and fixed to the bottom of scraper 4, falls into the bottom of sampling tube 1 and covers the crack on the surface of sampling tube 1, filling the space from the bottom of scraper 4 to the bottom of sampling tube 1. The rubber pad 403, after being squeezed by scraper 4, adheres to the inner wall of the bottom of sampling tube 1, preventing the yak semen inside sampling tube 1 from leaking out of the crack.

[0035] For temporary small-scale sampling, place your finger on the top edge of the sampling groove 502 and slowly pull the sealing cap 501 along with the sample box 5 out of the storage groove 302. Unscrew the sealing cap 501 from the top of the sample box 5. Pour some of the yak semen collected inside the sampling tube 1 into the sample box 5. Tighten the sealing cap 501 back onto the sample box 5 to ensure a good seal. Place the sample box 5 along with the sealing cap 501 back into the storage groove 302. The rubber retaining ring 303, fitted into the retaining groove 503, will prevent the sample box 5 from falling out of the storage groove 302.

[0036] The transparent plastic protective sleeve 6 protects the sampling tube 1 while the internal label strip 602 is located between the transparent plastic protective sleeve 6 and the sampling tube 1, which can clearly display the label information of the yak semen collected inside the sampling tube 1.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
