Description

Technical Field

[0001] The invention belongs to the technical field of boar semen quality detection, relates to a technology for improving the accuracy of a boar semen quality detection structure, and specifically relates to a boar semen quality detection sampler and a quality detection device. Background Art

[0002] In animal husbandry, especially in modern pig farming, the genetic performance and reproductive health of breeding boars directly affect the production efficiency and economic benefits of the entire industry. In order to ensure the breeding effect, it is crucial to evaluate the semen quality of breeding boars. This not only involves the quantity of semen, but more importantly, the quality of semen, including indicators such as sperm motility, concentration, and morphology. Traditional semen testing methods usually rely on laboratory environments and professional equipment, which is not only costly, but also easily causes sample degradation in the process from sampling to testing, affecting the accuracy and real-time nature of the test results.

[0003] Although there are some portable testing devices and test strips on the market, these methods still face many challenges when sampling semen. The ejection of pig semen is mainly divided into three stages, namely the prodromal stage, the main stage rich in sperm, and the post-dromal stage. The prodromal stage is small in volume and rich in sperm in small quantities. The main stage is the main stage rich in semen. The semen in this stage usually has a high sperm concentration, good motility, and normal morphology. The post-dromal stage usually contains fewer sperm, with a lower sperm concentration, and may contain more dead sperm or sperm with abnormal morphology. Therefore, if sperm at different stages is used for sperm quality testing, it will also lead to different test results.

[0004] In a semen collection of pigs, generally about 200 mL of semen is obtained, and the semen will be stratified during the storage process. For example, heavier sperm will be deposited at the bottom of the container. For example, certain proteins or other solutes in the semen may form different layers due to different solubilities, and the collected semen itself is not suitable for shaking (the shaking action itself will affect the quality of the semen). Therefore, when sampling for quality inspection, the sampling layer is different, which will greatly affect the test results of the test paper. Summary of the invention

[0071] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] See also Figures 1 to 8 As shown, the specific embodiments provided by the present invention are as follows:

[0073] like Figure 1 to Figure 2 As shown, the first embodiment of the present invention provides a boar semen quality detection sampler, comprising:

[0074] An air pressure generating assembly 1 having a negative pressure generating chamber 101 and a positive pressure generating chamber 102;

[0075] N samplers 2 having a standard cavity 201 and a compensation cavity 202;

[0076] Wherein, the standard chamber 201 is connected to the positive pressure generating chamber 102;

[0077] Wherein, the compensation chamber 202 is communicated with the negative pressure generating chamber 101;

[0078] Furthermore, the standard chamber 201 and the compensation chamber 202 are in one-way communication;

[0079] The one-way connection means that the boar semen can only flow from the standard chamber 201 to the compensation chamber 202;

[0080] The volumes V1 of the standard cavities 201 of the N samplers 2 are equal;

[0081] Wherein, the N samplers 2 are at least divided into a first sampling group, a second sampling group and a third sampling group;

[0082] Moreover, H1>H2>H3;

[0083] H1 is the distance between the center line L1 of the first sampling group and the center line M of the air pressure generating assembly 1;

[0084] H2 is the distance between the center line L2 of the first sampling group and the center line M of the air pressure generating assembly 1;

[0085] H3 is the distance between the center line L3 of the first sampling group and the center line M of the air pressure generating component 1.

[0086] In this embodiment, the air pressure generating assembly 1 is used to generate negative pressure and positive pressure in the negative pressure generating chamber 101 and the positive pressure generating chamber 102 respectively.

[0087] Since the compensation chamber 202 is connected to the negative pressure generating chamber 101 , the negative pressure state is synchronized to the compensation chamber 202 of each sampler 2 , further forming a negative pressure in the standard chamber 201 to absorb the semen of the boar.

[0088] On the basis of the above, one factor that affects the accuracy of the boar semen test result is the amount of semen. In the prior art, it is difficult to control the amount of semen manually, for example, dripping too much or too little semen on the test paper, which results in large differences in each test result.

[0089] Based on this, the volume V1 of each standard cavity 201 is fixed and equal, so that when the positive pressure state in the positive pressure generating chamber 102 is synchronized to the standard cavity 201, that is, when gas is delivered to the standard cavity 201, all the semen in the standard cavity 201 can be discharged, that is, dripped onto the test paper, thereby ensuring that the semen absorption and dripping amounts of multiple samplers 2 are completely consistent, thereby reducing the impact of different amounts of semen on the test results. In order to further ensure that the absorption amount of the standard cavity 201 of each sampler 2 is consistent, it is necessary to ensure that the negative pressure in the compensation cavity 202 and the standard cavity 201 under the negative pressure state can meet the semen filling all the standard cavities 201, and a part of it enters the compensation cavity 202, thereby ensuring that when the semen drips, the dripping amount of each sampler 2 is the volume V1. On the basis of the above, the compensation chamber 202 and the standard chamber 201 are unidirectionally connected, that is, semen can only enter the compensation chamber 202 from the standard chamber 201, and partially flow in the opposite direction, so as to avoid that when the standard chamber 201 is dripped, part of the semen in the compensation chamber 202 also enters the standard chamber 201 and is dripped, so as to ensure that the semen dripping amount of multiple samplers 2 remains consistent.

[0090] On the basis of the above, the N samplers 2 are divided into three groups.

[0091] Specifically, the distance L1 of the first sampling group is the farthest, so as to absorb the bottom layer of the boar semen after sedimentation and stratification. The distance L2 of the second sampling group is in the middle, so as to absorb the middle layer of the boar semen after sedimentation and stratification. The distance L3 of the third sampling group is the closest, so as to absorb the top layer of the boar semen after sedimentation and stratification.

[0092] That is to say, this embodiment can simultaneously absorb each layer of semen after sedimentation and stratification, so as to comprehensively judge the quality of the boar semen and ensure the accuracy of the test results.

[0093] In a specific embodiment, the air pressure generating device is a pneumatic device.

[0094] In one embodiment, the air pressure generating device is a manual device, such as an air bag or a piston assembly.

[0095] In a specific embodiment, the number N of the samplers 2 is 6, and the number of each sampling group is 2.

[0096] That is to say, the boar semen quality detection sampler provided in this embodiment has:

[0097] Improve detection accuracy:

[0098] By precisely controlling the volume V1 of the standard chamber 201 of each sampler 2, it is ensured that the amount of semen sampled and dripped each time is consistent, thereby reducing the influence of human operation on the test results.

[0099] The one-way connection design between the standard chamber 201 and the compensation chamber 202 ensures that semen can only enter the compensation chamber 202 from the standard chamber 201, avoiding reverse flow and improving the consistency and reliability of the test results.

[0100] Reflects the overall quality of semen:

[0101] By setting up two groups of samplers at different heights, it is possible to sample different layers of the boar semen after sedimentation and stratification, which can fully reflect the overall quality of the boar semen and avoid the interference of stratification on the test results.

[0102] Significant economic benefits:

[0103] It has improved the accuracy and efficiency of boar semen quality testing, reduced the cost of misjudgment and repeated testing, improved the breeding efficiency and genetic performance of boars, and brought significant economic and production benefits to the entire pig industry.

[0104] Through the above advantages, the boar semen quality detection sampler of the present invention can perform semen quality detection more efficiently and accurately, meet the high standards of semen quality assessment in the modern pig industry, and improve the genetic performance and reproductive efficiency of boars.

[0105] like Figures 1 to 3 As shown, the second embodiment of the present invention provides a boar semen quality detection sampler, and on the basis of the first embodiment, the air pressure generating component 1 includes a variable volume cavity 103;

[0106] The negative pressure generating chamber 101 and the variable volume chamber 103 are in one-way communication;

[0107] The positive pressure generating chamber 102 and the variable volume chamber 103 are in one-way communication;

[0108] The variable volume cavity 103 is subjected to an external force to replenish gas into the positive pressure generating chamber 102 and extract gas from the negative pressure generating chamber 101, or the variable volume cavity 103 replenishes gas into the positive pressure generating chamber 102 and extracts gas from the negative pressure generating chamber 101 through a driving member displaced along a first direction;

[0109] The first direction is the axial direction of the variable volume cavity 103;

[0110] Furthermore, the extraction of gas within the negative pressure generating chamber 101 at least satisfies the requirement that the boar semen enters the compensation chamber 202 .

[0111] In this embodiment, the variable volume cavity 103 is used to allow the formation of positive pressure and negative pressure.

[0112] Among them, positive pressure refers to the delivery of gas into the standard chamber 201 to discharge the semen in the standard chamber 201. Negative pressure refers to the extraction of gas from the compensation chamber 202 and the standard chamber 201 to form a negative pressure, so that the standard chamber 201 absorbs semen.

[0113] In a specific embodiment, the air pressure generating component 1 is an airbag, and the cavity inside the airbag is the variable volume cavity 103. The positive pressure and negative pressure of the variable volume cavity 103 are formed by manually pressing the airbag.

[0114] In a specific embodiment, the air pressure generating component 1 is a piston cylinder 104 , and the piston chamber of the piston cylinder 104 is a variable volume chamber 103 , and positive and negative pressure states of the piston chamber can be formed by pushing and pulling the piston rod 105 .

[0115] On the basis of the above, the negative pressure generating chamber 101 and the positive pressure generating chamber 102 are both unidirectionally connected to the variable volume chamber 103. That is to say, when the variable volume chamber 103 forms a negative pressure, it acts on the negative pressure generating chamber 101 alone to extract the gas in the negative pressure generating chamber 101, and synchronizes it to the compensation chamber 202 and the standard chamber 201. When the variable volume chamber 103 forms a positive pressure, it acts on the positive pressure generating chamber 102 alone to transport gas to the positive pressure generating chamber 102, and synchronizes it to the standard chamber 201. Of course, as mentioned above, in order to ensure that the amount of semen absorbed by each sampler 2 is certain, it is necessary to ensure that the semen enters the compensation chamber 202 to represent that the semen has completely filled the standard chamber 201.

[0116] like Figures 3 to 5 As shown, the third embodiment of the present invention provides a boar semen quality detection sampler, and based on the previous embodiment, the negative pressure generating chamber 101 is unidirectionally connected with the variable volume chamber 103 through a one-way member 13;

[0117] The positive pressure generating chamber 102 is in one-way communication with the variable volume chamber 103 via a one-way member 24;

[0118] Wherein, the one-way member 3 includes a blocking member 301 and an elastic member 302;

[0119] The elastic member 1 302 applies an elastic force F1 to the blocking member 1 301 along a second direction to seal the negative pressure generating chamber 101;

[0120] Wherein, the one-way member 4 includes a blocking member 401 and an elastic member 402;

[0121] The second elastic member 402 applies an elastic force F2 to the second blocking member 401 along a third direction to seal the positive pressure generating chamber 102;

[0122] Furthermore, the second direction is the direction from the variable volume cavity 103 to the negative pressure generating chamber 101;

[0123] Furthermore, the third direction is the direction from the positive pressure generating chamber 102 to the variable volume chamber 103 .

[0124] In this embodiment, in order to ensure that the negative pressure generating chamber 101 and the positive pressure generating chamber 102 work independently, a one-way member 1 3 and a one-way member 2 4 are added.

[0125] Specifically, the elastic member 302 applies an elastic force F1 to the blocking member 301, so that the blocking member 301 moves toward the variable volume cavity 103 when subjected to negative pressure to open the negative pressure generating cavity. When subjected to positive pressure, since the direction of the force is consistent with the direction of the elastic force F1, the blocking member 301 does not move toward the variable volume cavity 103, thereby maintaining the airtightness of the negative pressure generating cavity.

[0126] Specifically, the elastic member 402 applies an elastic force F2 to the blocking member 401, so that the blocking member 401 moves away from the variable volume cavity 103 when subjected to positive pressure to open the positive pressure generating cavity. When subjected to negative pressure, since the direction of the force is consistent with the direction of the elastic force F2, the blocking member 401 will not move away from the variable volume cavity 103, thereby maintaining the sealing of the positive pressure generating cavity.

[0127] Of course, the communication port of the negative pressure generating chamber is toward the negative pressure generating chamber, and the communication port of the positive pressure generating chamber is toward the variable volume chamber 103. Moreover, the arrangement directions of the elastic member 1 302 and the elastic member 2 402 are opposite.

[0128] In a specific implementation, the blocking member 1 301 and the blocking member 2 401 are blocking balls, and the elastic member 1 302 and the elastic member 2 402 are springs.

[0129] like Figure 6 to Figure 7 As shown, the fourth embodiment of the present invention provides a boar semen quality detection sampler, and based on the previous embodiment, the sampler 2 includes a sampling tube body 203;

[0130] Wherein, the sampling tube body 203 is a hollow structure to form the standard cavity 201 and the compensation cavity 202;

[0131] The standard volume chamber 201 is connected to the positive pressure generating chamber 102 through an air inlet pipe 501;

[0132] The compensation chamber 202 is connected to the negative pressure generating chamber 101 through an exhaust pipe 502;

[0133] Furthermore, the standard chamber 201 and the compensation chamber 202 are in one-way communication;

[0134] Furthermore, a sampling port 204 is provided at the end of the standard cavity 201 away from the compensation cavity 202 .

[0135] In this embodiment, the sampling tube body 203 has three ports, wherein the port located at the upper portion of the sampling tube body 203 is used to connect with the exhaust pipeline 502 to form a connection with the positive pressure generating chamber 102 .

[0136] The port located on the side wall of the standard chamber 201 is used to connect with the air inlet pipeline 501 to connect the standard chamber 201 with the negative pressure generating chamber 101. The port located at the bottom of the standard chamber 201 is used as a sampling port 204 to absorb semen.

[0137] The fifth embodiment of the present invention provides a boar semen quality detection sampler, and based on the previous embodiment, the standard chamber 201 and the compensation chamber 202 are unidirectionally connected through a one-way member 3 6;

[0138] Wherein, the one-way member 3 6 is a one-way valve;

[0139] Furthermore, the one-way valve only opens toward the compensation cavity 202 .

[0140] In this embodiment, the one-way member 3 6 is used to limit the semen in the compensation chamber 202 from flowing back into the standard chamber 201, thereby ensuring that the semen can only flow in one direction, ensuring the accuracy and consistency of the amount of semen dripping.

[0141] The sixth embodiment of the present invention provides a boar semen quality detection sampler, and based on the previous embodiment, comprises:

[0142] A calibration component 7 connected to the air pressure generating component 1;

[0143] The calibration member 7 extends radially along the air pressure generating assembly 1 so as to abut against the end surface of the container when the boar semen quality detection sampler is sampling.

[0144] In this embodiment, when the device is inserted into the container carrying semen to take a sample, the calibration piece 7 abuts against the end face of the container. On the one hand, the stability of the device is maintained during sampling to prevent the device from shaking and affecting the activity of sperm. On the other hand, it serves as a calibration of the maximum insertion depth to prevent the device from being excessively inserted into the container, ensuring that the distance the device is inserted into the container is consistent each time, so as to ensure relative consistency of the semen suction position.

[0145] In a specific embodiment, the calibration member 7 is composed of a pair of calibration plates arranged on the side walls of the air pressure generating assembly 1 .

[0146] The seventh embodiment of the present invention provides a boar semen quality detection sampler, and based on the previous embodiment, comprises:

[0147] A connecting frame 8 connected to the air pressure generating assembly 1;

[0148] The N samplers 2 are arranged along the circumference of the connecting frame 8 according to their corresponding distances.

[0149] In this embodiment, the connecting frame 8 is used to assemble a plurality of samplers 2 , and the plurality of samplers 2 are arranged on the circumferential wall surface of the connecting frame 8 .

[0150] In a specific embodiment, a plurality of samplers 2 are arranged in a staggered manner to ensure that the sampling areas of each sampler 2 are different, thereby ensuring the comprehensiveness of semen extraction.

[0151] In a specific embodiment, it is further found that due to the turbidity of semen, it is difficult for the operator to visually find out whether the sampler 2 is inserted to the set depth of semen, so a marking ring is added to the connecting frame 8. The marking ring 801 serves as a visual auxiliary function for the operator, so that the operator can easily observe the current insertion depth of each sampler 2 to improve the accuracy of sampling. For example, the marking ring 801 corresponding to the first sampling group is painted red, the marking ring 801 corresponding to the second sampling group is painted yellow, and the marking ring 801 corresponding to the third sampling group is painted green. The color of each group of marking rings 801 can help the operator quickly identify the position and depth of the sampler 2, thereby improving the convenience and accuracy of operation.

[0152] In a specific embodiment, the identification ring 801 can be used as a flow stabilizing structure. Specifically, when multiple samplers 2 are sampling, there may be a situation where semen fluctuates, and this fluctuation can affect the activity of sperm. Therefore, the identification ring 801 can slow down this fluctuation to a certain extent to avoid the adverse effect of the sampling process on sperm activity.

[0153] like Figures 1 to 8 As shown, the eighth embodiment of the present invention provides a boar semen quality detection device, comprising:

[0154] The boar semen quality detection sampler as described in any one of the above embodiments;

[0155] Detection box 9, with detection test paper;

[0156] The detection box 9 has N detection windows 901 corresponding to the number of samplers 2.

[0157] Preferably, each of the detection windows 901 has a number corresponding to each sampler 2;

[0158] Among them, the boar semen is dripped into the detection windows 901 with corresponding numbers in the order of the first sampling group, the second sampling group and the third sampling group.

[0159] In this embodiment, the specific operations are as follows:

[0160] The number of samplers 2 is 6, and the number of detection windows 901 is 6, which correspond one to one with the numbers of samplers 2.

[0161] The semen sucked by each sampler 2 is dropped into the detection window 901 with the corresponding number for detection.

[0162] For example, the first sampling group includes two samplers 2, and the samplers 2 are numbered 1 and 2. Correspondingly, the detection windows 901 are numbered 1 and 2 in sequence.

[0163] The second sampling group consists of two samplers 2, and the samplers 2 are numbered 3 and 4. Correspondingly, the detection windows 901 are numbered 3 and 4 in sequence, and so on.

[0164] After the test is completed, the quality of sperm in each layer can be learned by comparing the test results of each sampling group.

[0165] It was further discovered that during the sedimentation process of semen, sperm with higher motility and better quality would settle in the lower layer. The reason for this is related to the density and motility characteristics of sperm.

[0166] Density differences: Better quality sperm usually have normal shape and density. In contrast, poorer quality sperm may have an abnormal shape and a lower density. Denser sperm are more likely to settle to the bottom of a container under the pull of gravity.

[0167] Motility: Sperm with higher motility can swim more efficiently, but after a period of time, these sperm will gradually stop moving and settle to the bottom. In contrast, sperm with lower motility may float in the upper or middle layer of the liquid.

[0168] Gravity: Due to gravity, all substances in liquids will have a sedimentation process. The heavier parts of semen, such as healthy sperm, will gradually sink to the bottom of the container under the action of gravity.

[0169] Natural stratification: Semen will naturally stratify as it stands, with heavier sperm and cells settling to the bottom, while lighter parts, such as fewer or poorer sperm, and other components, float to the top.

[0170] In summary, during the sedimentation of semen, sperm with better quality usually settle in the lower layer due to their higher density and natural stratification. However, sperm with poorer quality may stay in the upper or middle layer due to differences in morphology and density. This phenomenon makes the sperm samples in the bottom layer usually have higher quality and vitality.

[0171] The detection reagents will have different color results for sperm of different quality. Generally speaking, the better the quality, the darker the color, and vice versa.

[0172] Based on this, the concentration of the detection reagent can be set to be the same, so that the color of the detection window 901 corresponding to the first sampling group is the darkest, and the color of the detection window 901 corresponding to the other sampling groups is lighter and equivalent. If the color development result of the detection window 901 is obviously inconsistent with the dripping order of the sampling group, it means that there is a deviation and error in the current sampling and detection process, and re-sampling and detection are required.

[0173] Alternatively, the concentration of the detection reagent can be set to be different, but in theory the color development results of the three sampling groups are consistent. If the color development results of the detection window 901 are obviously inconsistent, it means that an error has occurred in the current sampling and detection process, and re-sampling and detection are required.

[0174] Based on this, it can be seen that the boar semen quality detection device provided in this embodiment has the function of verifying the detection results, thereby further improving the accuracy of the detection results.
