[0028] The technical solutions in the embodiments of the present invention are described clearly and completely below. 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.
[0029] This embodiment provides a sampling device, which is mainly used to solve the problem that the existing sampling device cannot process the sample, thereby causing the sample to be inactivated and affecting the detection result.
[0030] Reference Figure 1 and Figure 3 As shown, during the sampling process, the sample needs to be extracted into the test tube 4 for storing the sample. However, during the transfer process, the sample may be inactivated due to various factors, thereby losing the detection value of the sample itself. In order to ensure that the sample leaving the human body can be better processed and its activity can be better preserved, in this embodiment, the temperature of the sample in transfer is controlled so that the ambient temperature of the sample is a temperature that the sample can adapt to, thereby solving the above problem. Specifically, a sampling device includes a sampling body, wherein the sampling body includes a first base 1 and a sliding device A second machine base 5 is provided on one side of the first machine base 1, wherein a liquid inlet channel 16 is provided in the first machine base 1, and a closed liquid outlet chamber 15 is formed between the first machine base 1 and the second machine base 5, wherein the liquid outlet chamber 15 is connected to the liquid inlet channel 16, and a temperature control unit is provided in the liquid inlet channel 16; the second machine base 5 slides relative to the first machine base 1 to change the air pressure in the liquid outlet chamber 15, thereby achieving the absorption of the sample, and the sample enters the sampling body through the liquid inlet channel 16, and the purpose of temperature regulation of the sample in the liquid inlet channel 16 is achieved by setting the temperature control unit.
[0031] It should be noted that the specific change of the air pressure in the above-mentioned liquid outlet chamber 15 is: when the second machine base 5 slides relative to the second machine base 5, the volume in the liquid outlet chamber 15 changes, and the liquid outlet chamber 15 is in a closed state, and air can only be taken in or out through the liquid inlet channel 16. When the volume in the liquid outlet chamber 15 becomes larger, the liquid outlet chamber 15 and the liquid inlet channel 16 present an entire suction process. At this time, the head of the first machine base 1 is close to the sample, so that the sample can be sucked into the liquid inlet channel 16.
[0032] It is worth mentioning that some samples that are difficult to extract may require some other instruments, such as a syringe, etc. In this case, the sample can enter the liquid inlet channel 16 by connecting the head of the first base 1 and the syringe.
[0033] In addition, the above-mentioned change in the air pressure is achieved based on the movement of the second base 5 relative to the first base 1. In this embodiment, a guide groove 17 is opened in the first base 1, and a guide ring 51 is provided on one side of the second base 5. The guide ring 51 is slidably arranged in the guide groove 17; and, a side of the first base 1 close to the second base 5 protrudes outward to form a fixed platform 11, and a telescopic cylinder 3 is provided on the second base 5, and one end of the telescopic rod of the telescopic cylinder 3 is arranged on the fixed platform 11; the operation of the telescopic cylinder 3 is used to achieve the purpose of making the second base 5 start to slide relative to the first base 1, thereby realizing a change in air pressure.
[0034] Reference Figure 3 As shown, the specific structure of the temperature control unit in the above-mentioned embodiment is as follows: the temperature control unit includes a temperature regulating chassis 6 and a fixing frame 61 for fixing the temperature regulating chassis 6, and a through groove 64 for the sample solution to pass through is formed between the temperature regulating chassis 6 and the side wall of the liquid inlet channel 16; the temperature of the liquid inlet channel 16 can be controlled by the setting of the temperature regulating chassis 6, and the temperature regulating chassis 6 can be placed in a hanging state by the setting of the fixing frame 61 to form the through groove 64, so that the sample solution can flow freely through the through groove 64.
[0035] It should be noted that the specific temperature control of the above-mentioned temperature control chassis 6 is carried out through manual control. Specifically, a temperature control button 2 is provided on the outside of the first base 1, and the temperature control button 2 is electrically connected to the temperature control chassis 6 through a fixing frame 61; the temperature control button 2 on the outside can be used to control the internal temperature of the liquid inlet channel 16. At the same time, different temperatures suitable for the survival of the samples can be selected according to different samples.
[0036] Reference Figure 3 and Figure 4As shown, when the sampling device is idle, in order to prevent outside air from entering the liquid inlet channel 16 and causing repeated pollution to the liquid inlet channel 16, it is necessary to cut off the air flow channel of the sampling device. In order to solve the above problem, in this embodiment, one side of the temperature control chassis 6 is provided with a closing member for closing the liquid inlet channel 16; the purpose of closing the liquid inlet channel 16 can be achieved by the closing member. When the closing member closes the liquid inlet channel 16, the liquid inlet channel 16 cannot be connected to the liquid outlet chamber 15, and the outside air naturally cannot enter the liquid inlet channel 16, thereby achieving the purpose of protecting the entire sampling device.
[0037] Specifically, the structure of the sealing member mentioned above is as follows: the sealing member includes a telescopic rod 62 arranged on the temperature control chassis 6, and a sealing block 63 is provided on one side of the telescopic rod 62, and the sealing block 63 is located in the rear half of the liquid inlet channel 16; the sealing block 63 slides in the liquid inlet channel 16 through the operation of the telescopic rod 62, and the sliding of the sealing block 63 causes the side wall of the sealing block 63 to continuously approach the side wall of the liquid inlet channel 16. Since the side wall of the liquid inlet channel 16 is arranged in a continuously inclined state, and the side wall of the sealing block 63 is the same as the side wall of the liquid inlet channel 16, when the sealing block 63 is against the side wall of the liquid inlet channel 16, the liquid inlet channel 16 is closed at this time, thereby achieving the purpose of protection.
[0038] It is worth mentioning that the purpose of setting the above-mentioned liquid inlet channel 16 in an inclined shape is to facilitate the flow of samples.
[0039] Reference Figures 1 to 5 As shown, in order to facilitate the reception of the sample in the liquid inlet channel 16 and prevent the sample from being contaminated by external air, in this embodiment, a conduit 14 for liquid discharge is provided on the side of the liquid outlet chamber 15 close to the liquid inlet channel 16, and a mounting groove 52 is provided in the second machine base 5, and a test tube 4 is slidably provided in the mounting groove 52, and the test tube 4 is sleeved on the outside of the conduit 14; by inserting the test tube 4, the test tube 4 can be aligned with the conduit 14, and then the sample in the liquid inlet channel 16 enters the test tube 4 through the conduit 14, thereby achieving the purpose of receiving the sample.
[0040] It should be noted that, in order to ensure that the test tube 4 can be inserted into the catheter 14 in an orderly manner, a plurality of support columns 131 are provided on the second machine base 5, and a limiting plate 13 is provided on the support column 131. The limiting plate 13 is provided with a limiting hole for the test tube 4 to pass through; the setting of the limiting hole can ensure the circumferential limitation of the test tube 4, thereby avoiding problems such as damage to the test tube 4 due to deviation.
[0041] It is worth mentioning that the test tube 4 mentioned above needs to be inserted into the installation groove 52 before starting to extract the sample, which can also ensure that the air pressure in the liquid outlet chamber 15 changes effectively.
[0042] In order to facilitate the taking of the entire sampling device, a plurality of handles 12 are provided on the second base 5 for people to grasp conveniently.
[0043] In order to ensure that the air pressure in the liquid outlet chamber 15 changes in an orderly manner, it is necessary to set a sealing structure for each connection, specifically, the connection between the guide slide ring 51 and the guide slide groove 17, and the connection between the test tube 4 and the mounting groove 52, and the above-mentioned sealing structure can be satisfied in the form of a sealing gasket.
[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
