Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a piglet nasal cavity sampler. Background Art

[0002] Piglets, also called piglets or piglets, are pigs that grow to about 30 kilograms from birth. Because the immune system of piglets is not fully developed and they are susceptible to diseases, piglets have high requirements for the environment and need to be sampled from time to time to analyze their health so that feeding strategies and breeding environments can be adjusted in time to ensure their healthy growth. Conventional samplers include a sampling tube and a sampler adhesive component set at one end of the sampling tube. They are not reasonably designed for the sampling of piglets. In some large pig farms, there are many piglets and the sampling time is tight. When samplers use conventional samplers to take nasal samples of piglets, there will be many problems:

[0003] (1) Because piglets have small nostrils and the adhesive parts of the sampler are large, the sampler will scrape the inside of the nasal cavity several times during sampling, which can easily cause stress reactions in piglets, weaken their bodies, and make it difficult for them to survive;

[0004] (2) Conventional sampling tubes are hard plastic tubes. If the sampling personnel are inexperienced, it is easy to irritate the inside of the piglet's nasal cavity during the sampling process, and even cause nasal mucosal bleeding;

[0005] (3) During the operation, the piglets struggled because they felt a strong foreign body sensation in their nasal cavity, resulting in insufficient sampling depth and unqualified samples;

[0006] (4) When the sampling is completed and the sample is placed in the sample preservation solution, the sampling tube is not easy to break, which affects the sampling efficiency. Utility Model Content

[0007] Aiming at the technical problems that the sampler's adhesive parts are large and easy to irritate the piglets, the sampling depth is insufficient, and the sampling tube is not easy to break when sampling piglets, the utility model provides a piglet nasal sampler, which has little irritation to the piglet's nasal cavity and realizes gentle and accurate sampling.

[0008] The technical solution of this utility model is as follows:

[0009] A piglet nasal sampler comprises a sampling tube, one end of which is connected to an elastic sampling membrane, the outer surface of which is provided with adsorption villi, the sampling tube is also connected to an air bag, the air bag is used to inflate the inner surface of the elastic sampling membrane to expand the elastic sampling membrane, a limiting ring made of a flexible material is sleeved on the sampling tube, two blades are relatively arranged on the inner side of the limiting ring, the length of the blades is not less than the diameter of the sampling tube, and the limiting ring is slidably connected to the sampling tube.

[0010] The outer surface of the elastic sampling membrane refers to the side that contacts the piglet's nasal cavity when the piglet nasal sampler is in use.

[0011] Furthermore, the elastic sampling membrane is stored inside the sampling tube when not inflated.

[0012] Furthermore, the airbag is provided with anti-slip protrusions.

[0013] It is not easy for the sampler to slip when pressing the airbag, which makes it easy to adjust the pressing force.

[0014] Furthermore, the sampling tube is a through tube with openings at both ends, and the air bag is connected to the other end of the sampling tube to form a closed environment inside the piglet nasal sampler.

[0015] Furthermore, a handle is fixed to one end of the airbag away from the sampling tube, and an anti-slip protrusion is arranged on the outer surface of the handle.

[0016] It prevents sampling personnel from slipping and saves effort when collecting.

[0017] Furthermore, the sampling tube is a blind tube with one end open and the other end closed, and the air bag is connected to the air hole arranged on the side wall of the sampling tube through a pipeline.

[0018] Furthermore, two sliding blocks are arranged opposite to each other on the inner side of the limiting ring, and two sliding grooves are arranged correspondingly on the outer surface of the sampling tube.

[0019] Furthermore, the elastic sampling membrane is made of rubber, and the sampling tube is made of silicone.

[0020] The beneficial effects of the utility model are:

[0021] The utility model provides a piglet nasal sampler, in which each component cooperates reasonably, and can reduce the piglet's foreign body sensation while achieving accurate sampling and improving sampling efficiency. Before sampling, the sliding limit ring can adjust the depth of the elastic sampling membrane extending into the nasal cavity during sampling, and the elastic sampling membrane is stored inside the sampling tube, reducing the possibility of the elastic sampling membrane being exposed to the external environment and being contaminated; during sampling, the sampling tube is soft in texture and will not accidentally injure the nasal mucosa when it contacts the inside of the nasal cavity; when the sampling target is reached, the sampler presses the airbag, and the elastic sampling membrane is forced to expand. By controlling the airbag, the size of the elastic sampling membrane inside the nasal cavity is adjusted to absorb the villi and adhere to the sample, without scratching the inside of the nasal cavity, reducing the piglet's foreign body pain, and being more humane; after sampling, press the limit ring with two fingers to let the blade on the limit ring cut the sampling tube, so that the sample can easily enter the sample preservation solution.

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, 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 them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0030] Example 1

[0031] Reference Figure 1-Figure 3A piglet nasal sampler comprises a sampling tube 2 made of silicone material. The sampling tube 2 is a blind tube with one end open and the other end closed. An elastic sampling membrane 1 made of rubber material for adsorbing villi is adhered to the outer surface and is sealed and connected to the open end of the sampling tube 2. The elastic sampling membrane 1 is stored in the sampling tube 2 when not sampling. An air bag 4 is connected to an air hole arranged on the side wall of the sampling tube 2 through a pipeline. The air bag 4 is used to inflate the inner surface of the elastic sampling membrane 1 to expand the elastic sampling membrane 1. An anti-slip protrusion is arranged on the outer surface of the air bag 4. A limiting ring 3 of flexible material is sleeved on the sampling tube 2. The limiting ring 3 is slidably connected to the sampling tube 2. Two sliders are arranged relatively on the inner side of the limiting ring 3. Two slide grooves are correspondingly arranged on the outer surface of the sampling tube 2. Two blades 5 are also arranged relatively on the inner side of the limiting ring 3. The length of the blade 5 is equal to the diameter of the sampling tube 2.

[0032] During the sampling process, the piglet nasal sampler is first taken out from the sealed bag. At this time, the elastic sampling membrane 1 is stored in the sampling tube 2 to reduce the possibility of the elastic sampling membrane being exposed to the external environment and contaminated. The position of the limiting ring 3 on the sampling tube 2 is slidably adjusted according to the depth of the piglet's nasal cavity as needed, and the sampling tube 2 is inserted into the piglet's nasal cavity. When the limiting ring 3 contacts the piglet's nose, it reaches the target position, and the air bag 4 is pressed. The elastic sampling membrane 1 pops out and expands, and the outer surface of the elastic sampling membrane 1 contacts the inside of the piglet's nasal cavity for adhesion sampling. , and then release the air bag 4 to shrink the elastic sampling membrane 1. Repeat this process many times. The elastic sampling membrane 1 will alternately expand and shrink to fully contact the inside of the nasal cavity for sampling. After sampling, release the air bag 4, take out the piglet nasal sampler, put the elastic sampling membrane 1 with the sample into the sample preservative solution, slide the limiting ring 3 to the appropriate position according to the shape of the device for holding the sample preservative solution, and then press the limiting ring 3 with the thumb and index finger. The limiting ring 3 is deformed under force, and the blade 5 cuts off the sampling tube 2. The sample enters the sample preservative solution and is sealed and preserved for inspection.

[0033] Example 2

[0034] Reference Figure 4 The difference between Example 2 and Example 1 is that the sampling tube 2 is a through tube with openings at both ends, the elastic sampling membrane 1 is connected to one end of the sampling tube 2, and the air bag 4 is connected to the other end of the sampling tube 2, so that a closed environment is formed inside the piglet nasal sampler.

[0035] Example 3

[0036] Reference Figure 5 On the basis of Example 2, a handle 6 is fixed to one end of the airbag 4 away from the sampling tube 2, and an anti-slip protrusion is provided on the outer surface of the handle 6.
