Description

Technical Field

[0001] This utility model relates to the field of laboratory equipment technology, and in particular to a medical laboratory pipette tip detachment aid device. Background Technology

[0002] In various experiments in medical laboratories, vacuum conditions are required for normal experimental operations such as sample extraction, filtration, drying, and extraction. Therefore, medical laboratories use vacuum pumps to assist in various experimental operations. In particular, in experimental operations such as sample extraction and filtration, it is common to use a vacuum pump with a pipette tip to aspirate and transfer liquids.

[0003] Currently, after completing liquid aspiration, laboratory operators need to manually disconnect the pipette tip from the vacuum pump connection port before proceeding to the next experimental step. However, this manual disassembly process has several drawbacks: firstly, it is cumbersome and slow, especially when processing large volumes of samples frequently, consuming significant time and effort and reducing experimental efficiency; secondly, manually removing the pipette tip exposes the operator's hands to the biological sample, greatly increasing the risk of cross-infection and compromising experimental safety. This is a pressing issue for medical laboratories with extremely high hygiene and safety requirements. Utility Model Content

[0004] To address the technical problems of existing technologies, such as the cumbersome manual removal of the pipette tip from the vacuum pump, the risk of contact with the pipette tip containing biological samples, the increased risk of cross-infection, and the reduced experimental efficiency and safety, this invention provides the following technical solution.

[0005] This utility model discloses a medical laboratory-grade syringe tip detachment device, comprising two mounting plates fixed to one side of the upper part of a vacuum device. One end of each mounting plate is fixedly connected to a side plate, and the other end of each mounting plate is fixedly connected to a detachment plate with a placement groove at its upper end. A movable rod with a handle at one end is slidably connected between the side plate and the detachment plate. The movable rod passes through the upper part of one end of the detachment plate and is fixedly connected to a pusher via a fixing block. The pusher has a semi-ring body coaxial with the placement groove. The placement groove and the semi-ring body respectively block a connecting seat and a syringe tip that are connected to each other. The movable rod pushes the semi-ring body and the syringe tip to move away from the connecting seat.

[0006] As a further technical solution, a stop ring is fixedly provided on the portion of the movable rod located between the side plate and the release plate, and a spring sleeved on the outer periphery of the movable rod is fixedly connected between the stop ring and the release plate.

[0007] As a further technical solution, the semi-ring body is provided with a number of annularly distributed balls on one side of the outer wall of the gun head.

[0008] As a further technical solution, a guide strip is fixedly provided on the outer wall of the movable rod.

[0009] As a further technical solution, the connecting seat includes a connecting sleeve passing through the placement groove and a seat ring located between the side plate and the release plate, which is blocked by the release plate.

[0010] As a further technical solution, the gun head includes a connecting end placed in the axial direction of the semi-annular body and a gun ring with an outer diameter larger than that of the semi-annular body.

[0011] The beneficial effects of this invention are as follows: When it is necessary to detach the pipette tip, simply pushing or pulling the handle will cause the movable rod to drive the detachment component to separate the pipette tip, eliminating the need for manual removal. This greatly simplifies the operation process, significantly saving time and improving experimental efficiency in batch sample processing. Simultaneously, it avoids direct contact between the operator's hands and the used pipette tip, reducing the possibility of cross-infection caused by sample contact and lowering the risk of cross-infection. This provides a safer working environment for laboratory operators and enhances the practicality and adaptability of vacuum equipment in medical laboratory environments. Attached Figure Description

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] like Figure 1 and Figure 2 As shown, this utility model discloses a medical laboratory pipette tip detachment device, which is installed on the upper part of a vacuum device 10. It includes two mounting plates 1 fixed to one side of the upper part of the vacuum device 10. The vacuum device 10 includes existing components such as a vacuum pump, a waste liquid bottle, and a suction tube. The suction tube is connected to a connecting seat 8, which is used to connect a pipette tip 9. The pipette tip 9 is used for liquid suction operation.

[0016] The connecting seat 8 includes a seat ring 801 and a connecting sleeve 802. The seat ring 801 is made of high-strength, corrosion-resistant engineering plastic. One side of the seat ring 801 has a cylindrical structure with internal threads, which can be tightly screwed into the external threads of the suction tube port of the waste liquid bottle to ensure a stable connection. The other side of the seat ring 801 is the connecting sleeve 802, which is made of soft and highly elastic silicone. The inner diameter of the connecting sleeve 802 is slightly smaller than the outer diameter of the nozzle 9. When the nozzle 9 is inserted, it can form a tight seal to prevent air leakage and ensure the effective transmission of negative pressure in the vacuum device 10. The nozzle 9 includes a nozzle ring 901 and a connecting end 902. The connecting end 902 is located on one side of the nozzle ring 901 and is connected to the connecting sleeve 802. The other side of the nozzle ring 901 is used to draw liquid.

[0017] like Figure 2 , Figure 3 and Figure 4As shown, in a preferred embodiment, a side plate 2 is fixedly connected to the same end of the two mounting plates 1, and a release plate 3 is fixedly connected to the other end of the two mounting plates 1 away from the side plate 2. The release plate 3 has a placement groove 301 at its upper end, and the placement groove 301 has a semi-circular structure. When accurately releasing the gun head 9, the connecting sleeve 802 passes through the placement groove 301 and is placed at the bottom of the placement groove 301. The seat ring 801 is located between the side plate 2 and the release plate 3. The outer diameter of the seat ring 801 is larger than the inner diameter of the placement groove 301, so that the seat ring 801 is stopped by the release plate 3.

[0018] In a preferred embodiment, a movable rod 4 is slidably connected between the side plate 2 and the release plate 3. A handle 5 is provided at one end of the movable rod 4 located outside the side plate 2, and the handle 5 is used to push and pull the movable rod 4. A pusher 6 is fixedly connected to the upper part of one end of the movable rod 4 passing through the release plate 3 via a fixing block 403. The pusher 6 is used to detach the nozzle 9, disengaging the nozzle 9 from the connecting seat 8, thus preventing the operator's hand from touching the nozzle 9.

[0019] Specifically, the pusher 6 has a semi-ring 601 coaxial with the placement groove 301. The upper part of the semi-ring 601 has an opening for inserting the connecting end 902. The placement groove 301 and the semi-ring 601 respectively stop the seat ring 801 and the gun ring 901. At this time, the seat ring 801 is located on the left side of the release plate 3, the semi-ring 601 is located on the right side of the release plate 3, and the gun ring 901 is located on the right side of the semi-ring 601. When the movable rod 4 pushes the semi-ring 601 and the gun ring 901 to move away from the seat ring 801, the connecting sleeve 802 and the connecting end 902 can be separated and detached, completing the detachment operation of the gun head 9.

[0020] In a preferred embodiment, the semi-ring 601 abuts against one side of the outer wall of the gun ring 901. That is, the right side of the semi-ring 601 is provided with a plurality of annularly distributed balls 602. When the semi-ring 601 and the balls 602 push the gun ring 901, the balls 602 not only generate a thrust on the gun ring 901, but also generate a radial rotational force on the gun ring 901, which can further ensure the smooth disengagement of the gun ring 901 and the connecting end 902.

[0021] In a preferred embodiment, a guide strip 401 is fixedly provided on the outer wall of the movable rod 4 to prevent radial rotation of the movable rod 4 and ensure the accuracy of axial movement of the movable rod 4 and the pusher 6. A stop ring 402 is fixedly provided on the portion of the movable rod 4 located between the side plate 2 and the release plate 3. A spring 7 is sleeved on the outer periphery of the movable rod 402. The two ends of the spring 7 are fixedly connected to the stop ring 402 and the release plate 3, respectively. The elastic force of the spring 7 helps the movement of the pusher 6, making it easier to push the gun head 9 away from the connecting seat 8.

[0022] In use, the following steps are taken: First, pull the handle 5 to move the movable rod 4 toward the handle 5, stretching the spring 7 until the semi-ring 601 contacts the release plate 3. Then, place the connecting seat 8 and the gun head 9 into the placement groove 301 and the semi-ring 601 respectively, so that the placement groove 301 and the semi-ring 601 respectively stop the seat ring 801 and the gun ring 901. Then, release the handle 5, and the spring 7 retracts, causing the stop ring 402 to move. Under the elastic force of the spring 7, the movable rod 4 moves toward the gun head 9, that is, the semi-ring 601 and the gun ring 901 move away from the seat ring 801, and the connecting sleeve 802 separates from the connecting end 902, thus completing the disengagement operation of the gun head 9.

[0023] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
