Description

Technical Field

[0001] The utility model belongs to the field of animal husbandry and veterinary appliances, and in particular relates to a bird feather sample collector. Background Art

[0002] Birds are different from mammals. It is difficult to distinguish males or females by appearance when they are young. Generally, they can only be distinguished by appearance and behavior when they are one to several months old. This is quite troublesome for bird breeders who raise young birds in separate cabinets.

[0003] Bird sex gene detection technology can quickly and cheaply identify the sex of birds with an accuracy of up to 99.999% through sample collection, DNA extraction, specific fragment PCR amplification, and result analysis. In recent years, this technology has been rapidly promoted in the market. The first step of this technology is sample collection and preservation, and this step plays a key role in whether the test can be successful. For birds, samples such as blood, epithelial tissue, and feather follicles contain a full set of individual genetic material and can meet the genetic testing requirements for sex identification. However, feather samples cause the least trauma to individual poultry, have the lowest difficulty for farmers to collect samples, and are convenient to preserve.

[0004] Most of the disposable animal husbandry medical feather sample collectors in the prior art currently use disposable sealing bags to seal the feather samples, and one sample consumes one sample bag. The sample number is directly marked on the bag with a water-based pen. Although a single feather sample can be collected, it is not conducive to sample preservation when multiple samples are collected, and the sample bags will be consumed. In clinical work, bird brooding often requires a large number of tests at the same time. The above technology is prone to sample confusion. Therefore, a feather sample collector that can avoid sample confusion is needed. The utility model solves this technical problem. Utility Model Content

[0005] The utility model provides a bird feather sample collector, which can meet the needs of collecting a variety of feather samples and avoid sample confusion, thereby reducing cross contamination of samples during DNA extraction.

[0006] A bird feather sample collector comprises a collection box, a label area arranged on the collection box, and a plurality of storage cavities arranged in the collection box. An upper cover is arranged above the storage cavity.

[0007] Furthermore, the plurality of storage cavities gradually widen from one end to the other end.

[0008] Furthermore, the plurality of storage cavities are arranged in a circular array, so that the space of the collection box can be better utilized.

[0009] Furthermore, the label area includes a plurality of labels, and the plurality of labels are respectively arranged corresponding to the plurality of storage cavities.

[0010] Furthermore, the upper cover is rotatably connected to the top of the storage cavity, and one end of the upper cover is detachably clamped on the collection box. There are a plurality of upper covers, and each storage cavity is provided with an upper cover.

[0011] Furthermore, the side wall of the storage cavity is provided with a scale for conveniently observing the length of the feathers.

[0012] Furthermore, a limiting mechanism for limiting the position of the feather sample is provided in the storage cavity, and the limiting mechanism includes a pressure plate rotatably connected to one side of the storage cavity at one end, and the other end of the pressure plate is connected to the bottom end of the spring. An open groove is provided on the other side of the storage cavity, and the top end of the spring is connected to the top end of the open groove.

[0013] The technical effects of the utility model are as follows:

[0014] (1) The storage box is provided with a plurality of storage chambers, which can be used to collect a variety of feather samples. Different feather samples are collected in different storage chambers to avoid cross-contamination of samples. Moreover, the label area can clearly indicate which type of sample is collected in each storage chamber, thereby realizing the collection of a variety of feather samples and avoiding confusion of samples.

[0015] (2) Since the shape of the feather is sharper at one end and wider at the other end, the storage cavity in the device is designed to gradually widen from one end to the other, so that the space of the storage cavity can be effectively utilized;

[0016] (3) The upper cover can cover the top of the storage cavity, which can prevent dust from falling into the storage cavity and contaminating the sample, and protect the sample. It can also prevent the tester's hand from touching the front end of the hair follicle and affecting the test;

[0017] (4) The pressure plate in the limiting mechanism can limit the feather sample to prevent the feather from flying during the collection process, thereby avoiding affecting the collection work;

[0018] (5) The scale on the inner wall of the storage chamber can be used to observe whether the feather length meets the sample submission standard, thereby improving the quality of the samples submitted for inspection;

[0019] (6) Unlike the sample bags for collecting feather samples in the prior art, the marks made by the water-based pen on the sample bags are easily blurred. The label area in this solution is specifically used for marking to avoid the situation where the water-based pen marks are blurred. In addition, this device can collect multiple samples at one time, ensure the length of the feathers, and improve the quality of the samples sent for inspection. Compared with other existing collectors, this device achieves a multi-functional technical effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solution of the utility model will be clearly and completely explained below in conjunction with specific embodiments and drawings.

[0025] See also Figure 1-Figure 3 A bird feather sample collector comprises a collecting box 1, a label area arranged on the collecting box 1, and a plurality of storage chambers 4 arranged in the collecting box 1. An upper cover 2 is arranged above the storage chamber 4. The collecting box 1 in this embodiment is circular, and may also be other shapes during production, which will not be described in detail herein. Preferably, since at least 3-5 feathers to be tested are required to be placed in one storage chamber 4, the collecting box 1 needs to have a height of about 5 cm.

[0026] Furthermore, the plurality of storage cavities 4 gradually widen from one end to the other end. The storage cavity 4 in the present embodiment is fan-shaped, and may also be triangular, trapezoidal or other shapes that meet the above requirements during production, which are not listed here one by one.

[0027] Furthermore, a plurality of storage cavities 4 are arranged in a circular array, so that the space of the collection box 1 can be better utilized. The number of the storage cavities 4 in this embodiment is eight.

[0028] Furthermore, the label area includes a plurality of labels 8 , and the plurality of labels 8 are respectively disposed corresponding to the plurality of storage cavities 4 .

[0029] Furthermore, the upper cover 2 is rotatably connected above the storage cavity 4 , and one end of the upper cover 2 is detachably clamped on the collection box 1 . A plurality of upper covers 2 are provided, and one upper cover 2 is provided on each storage cavity 4 .

[0030] One end of the upper cover 2 in this embodiment is fixed above the storage cavity 4 and connected to the collection box 1. A bending portion is provided in the middle area near this end, so that the other end can be rotated by the bending portion to complete the opening and closing of the upper cover 2. Optionally, the upper cover 2 in this scheme can also be other types of structures as long as the function of the upper cover 2 in this scheme can be achieved.

[0031] See also Figure 1 The arc portion of the top surface of the collecting box 1 is the portion where the upper cover 2 can be bent.

[0032] Furthermore, the side wall of the storage chamber 4 is provided with a scale 6 for convenient observation of the feather length. Since feathers of insufficient length cannot be sent for sampling and testing, when one end of the feather is placed against the end of the storage chamber 4 and the position of the other end of the feather exceeds the scale 6 of 5 cm, the length is qualified and can be sent for sampling. In this embodiment, the feather sample must be at least 5 cm in length.

[0033] Furthermore, a limiting mechanism for limiting the position of the feather sample is provided in the storage chamber 4, and the limiting mechanism includes a pressing plate 5 rotatably connected to one side of the storage chamber 4 at one end, and the other end of the pressing plate 5 is connected to the bottom end of the spring 3. An opening groove 7 is provided on the other side of the storage chamber 4, and the top of the spring 3 is connected to the top of the opening groove 7. There are many rotation principles of the pressing plate 5, which can adopt the rotation principle of the upper cover 2, or can be realized by other methods, such as grooves in the side wall of the collection chamber, and holes on both sides of the groove, and then two connecting columns are fixed on both sides of the pressing plate 5, and the two connecting columns are respectively inserted into the two holes to realize the rotation, which will not be described in detail here. Figure 3 The inner wall of the receiving cavity 4 is a partial inner wall, not a complete inner wall.

[0034] Preferably, the device is made of PVC material and can be reused.

[0035] The working principle of the utility model is as follows:

[0036] When it is necessary to collect the feather sample into the storage chamber 4, the upper cover 2 needs to be opened to separate one end of the upper cover 2 from the collection box 1. Then, the pressing plate 5 can be pinched by hand and lifted upward, and the feather is placed between the pressing plate 5 and the bottom surface of the storage chamber 4, and one end of the feather is pressed against one end of the storage chamber 4. Then, the pressing plate 5 is lowered to press the feather, and the other end of the feather is observed to see whether it reaches the scale 6, that is, whether the length reaches 5 cm. If it reaches or exceeds the scale, it is qualified.

[0037] After collecting feathers of other types, they can be placed in other storage chambers 4 in the above manner to avoid cross contamination, and then a mark or the name of the sample type can be made on the corresponding label 8. Multiple feathers of the same type can be stored in the same storage chamber 4. After the collection is completed, the upper cover 2 is rotated downward to be locked on the side of the collection box 1.

[0038] The above two embodiments are only preferred embodiments of the present invention. Those skilled in the art can derive other embodiments from the above embodiments without creative work. Therefore, this application protects not only the above embodiments, but also the scope consistent with the principles and features of this application.
