Description

Technical Field

[0001] This utility model relates to the field of reagent sampling technology, specifically a reagent sampler. Background Technology

[0002] In the application of modern in vitro diagnostic reagents, reagent sampling is an important task. At present, reagent diagnostic samplers are mainly for blood, urine and other liquid secretions. Most of these reagent diagnostic samples are liquids, and the reagents need to be sent to the testing room for testing when used.

[0003] Therefore, in modern reagent sampling processes, testing mainly relies on pipetting equipment to sample reagents and transfer them to the testing equipment. In order to achieve rapid sampling, current pipetting equipment mainly adopts a piston structure. Although it is convenient to operate, in order to avoid cross-contamination of sampled reagents during application, the pipette tip usually needs to be replaced after each use. However, most current pipetting equipment has a multi-channel structure, with each channel corresponding to a pipette tip, and a large number of tips need to be replaced at the same time, making the operation very cumbersome. In view of this, this case was developed through in-depth research on the above problems. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides a reagent sampler, which solves the existing background technology problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sampler for a reagent, including a sampling handle, the sampling handle having a wrench-type structure, a piston sampling mechanism provided on the sampling handle, a diversion cap provided at the end of the sampling handle, a fan-shaped diversion channel integrally extending from the diversion cap, and a plurality of tubular transition heads provided on the diversion channel;

[0007] The integrated quick-release structure includes a slot, and a rectangular slot is provided at the front end of the diversion channel. The slot extends to several transition heads, and a sleeve is integrally connected to several sampling tubes. The sleeve is inserted into the slot. The sleeve is a rectangular plate, and the sleeve and the slot are in transition fit. The sleeve is provided with a slot, and an elastic buckle is provided on the diversion channel. The elastic buckle and the slot limit the movement.

[0008] Preferably, the end of the card sleeve is provided with a silicone ring structure, which seals the end of the slot.

A sampling control piston is installed inside the pressure regulating tube. A sampling control rod extends from the tail end of the sampling control piston. A rebound spring is embedded in the pressure regulating tube and contacts the sampling control piston.

[0010] Preferably, the elastic buckle includes a control seat, a slot is formed on one side wall of the sleeve, a control seat is provided at a corresponding position on the diversion channel, a limit spring is installed inside the control seat, a reverse push block is installed on the limit spring, and the end of the reverse push block penetrates through the side wall of the diversion channel and mutually limits the slot.

[0011] Preferably, the head end of the ferrule is provided with a sloping structure, and the ends of several sampling tubes are provided with sealing heads through one side of the ferrule, and the sealing heads are connected to several transition heads. Beneficial effects

[0012] This utility model provides a sampler for reagents. It offers the following advantages: The sampler features an integrated design of the ferrule and sampling tube, allowing for quick assembly and disassembly of the entire module via elastic snap-fit, avoiding the need for individual replacements. The shunt channel integrates a transition head and a silicone sealing ring, working in conjunction with a sealing head to ensure the sealing of multi-channel sampling, reducing cross-contamination.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides an implementation scheme: In the process of modern in vitro reagent testing, reagents are often sampled using a pipette before being placed into the testing device. However, in order to increase the total amount of sample taken at one time, current pipettes use a multi-channel sampling method. However, this method requires the sampling head to be replaced when collecting different samples. The conventional replacement methods are mainly divided into integrated replacement and multiple replacement. Multiple replacement requires the user to disassemble and assemble many sampling heads, which is inconvenient. Integrated replacement requires the entire pipette except for the control part, which is very wasteful.

[0019] To address the above issues, please refer to the appendix to the instruction manual. Figure 1-3 As can be seen, this application discloses a sampler for a reagent, including a sampling handle 1, which is a wrench-shaped structure. A piston sampling mechanism 2 is provided on the sampling handle 1. The sampling handle 1 provides a gripping part for the hand during use, which is convenient for operation. Sampling is performed using the piston sampling mechanism 2. A diversion cap 3 is provided at the end of the sampling handle 1. The diversion cap 3 is connected to the piston sampling mechanism 2. A fan-shaped diversion channel 4 extends integrally from the diversion cap 3. By controlling the piston sampling mechanism 2 to generate a negative pressure, the diversion effect of the diversion cap 3 is used to apply the negative pressure to the sampling part through several diversion channels to complete the sampling.

[0020] According to the instruction manual Figure 1-3 It can be seen that the lower part of the diversion channel 4 is provided with an integrated quick-release structure 6, and the diversion channel 4 is provided with several tubular transition heads 5. The integrated quick-release structure 6 is provided with several sampling tubes 7. The sampling tubes 7 correspond one-to-one with the transition heads 5 and are interconnected. The integrated quick-release structure 6 can quickly assemble and disassemble the sampling tubes 7. The sampling tubes 7 are the head parts that specifically contact the reagents. The number of sampling tubes 7 is multiple, which is suitable for simultaneous collection from multiple channels.

[0021] Then, according to the instruction manual attached Figure 1-3It can be seen that the above-mentioned integrated quick-release structure 6 includes a slot 61. The front end of the diversion channel 4 is provided with a rectangular slot 61. The slot 61 extends to several transition heads 5. Several sampling tubes 7 are integrally connected with a sleeve 62. The sleeve 62 is inserted into the slot 61. The sleeve 62 is a rectangular plate. The sleeve 62 and the slot 61 are in transition fit. The sleeve 62 is provided with a slot 63. The diversion channel 4 is provided with an elastic buckle 64. The elastic buckle 64 and the slot 63 limit the movement.

[0022] In the specific implementation process, the slot 61 at the front end of the diversion channel 4 serves as the space for installing the sleeve 62. The sleeve 62 is inserted from one side of the slot 61, so that the sleeve 62 is assembled in the slot 61. After the sleeve 62 is inserted into place, the slot 63 on the sleeve 62 will limit the movement of the sleeve 62 with the elastic buckle 64, so that the user knows that the sleeve 62 has moved into place and remains stable during use. The sleeve 62 and several sampling tubes 7 are integrally formed, so that the sleeve 62 and several sampling tubes 7 form an independent sampling module. During use, after the sampling tubes 7 and the sleeve 62 have been sampled a specified number of times, the sleeve 62 and several sampling tubes 7 can be replaced as a whole, and then a new sampling tube 7 can be installed. In this way, it is not necessary to replace the sampling tubes 7 one by one, which is convenient to operate. Secondly, it retains part of the diversion channel 4, which saves materials and is more environmentally friendly.

[0023] As a preferred option, the end of the ferrule 62 is provided with a silicone ring structure, which seals the end of the slot 61 to ensure sealing during the sampling process.

[0024] As a preferred option, further according to the appendix to the instruction manual... Figure 1-3 It can be seen that the piston sampling mechanism 2 mentioned above includes a pressure regulating tube 21. The pressure regulating tube 21 is installed on the sampling handle 1. The pressure regulating tube 21 is connected to the diverter cap 3. The sampling control piston 22 is installed inside the pressure regulating tube 21. The sampling control rod 23 extends from the tail end of the sampling control piston 22. The spring 24 embedded in the pressure regulating tube 21 contacts the sampling control piston 22.

[0025] In the specific implementation process, by pressing the sampling control tube, the air in the pressure regulating tube 21 is discharged from the sampling control tube, and the rebound spring 24 is squeezed in the process of the internal negative pressure state. Then, the sampling tube 7 is inserted into the reagent. The sampling control rod 23 is slowly released, and the sampling control piston 22 is slowly raised under the reverse push of the rebound spring 24. The reagent is drawn into the sampling tube 7 under the negative pressure through the passage formed by the sampling tube 7, the transition head 5, the diversion channel 4 and the pressure regulating tube 21.

[0026] As a preferred option, further according to the appendix to the instruction manual... Figure 1-3It can be seen that the above-mentioned elastic buckle 64 includes a control seat 641, a slot 63 is opened on one side wall of the sleeve 62, a control seat 641 is provided at a corresponding position on the diversion channel 4, a limit spring 642 is installed inside the control seat 641, a reverse push block 643 is installed on the limit spring 642, and the end of the reverse push block 643 penetrates the side wall of the diversion channel 4 and mutually limits the slot 63;

[0027] In the specific implementation process, the limiting spring 642 is installed through the control seat 641. Under normal conditions, the limiting spring 642 has the function of pushing the reverse push block 643 downward, so that the reverse push block 643 tends to move towards the slot 63. When the sleeve 62 is inserted, the head end of the sleeve 62 pushes the reverse push block 643 to squeeze the limiting spring 642. Then, when the sleeve 62 is inserted into place, the reverse push block 643 is inserted into the slot 63 under the action of the limiting spring 642, thereby achieving the limiting function of the sleeve 62.

[0028] As a preferred option, the head end of the ferrule 62 is provided with a sloping structure, and the ends of several sampling tubes 7 are provided with a sealing head 8 through one side of the ferrule 62. The sealing head 8 is connected to several transition heads 5 for easy insertion. After insertion, the sealing head 8 wraps around the transition head 5 to maintain a seal.

[0029] In summary, the sampler of this reagent adopts an integrated design of the ferrule 62 and the sampling tube 7, and the elastic buckle 64 enables quick assembly and disassembly of the entire module, avoiding the need for individual replacement. The diversion channel 4 integrates the transition head 5 and the silicone sealing ring, which, together with the sealing head 8, ensures the sealing of multi-channel sampling and reduces cross-contamination. Only the sampling module needs to be replaced, while core components such as the diversion cap 3 are retained, reducing consumable costs. The sloped ferrule 62 and spring limit design simplify the installation process. Compared with the cumbersome replacement of traditional components in stages or the waste of replacing the entire tube, this design balances efficiency, cost, and environmental protection.

[0030] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
