Description

An adaptive elastic clamping medical tube holder Technical Field

[0001] This utility model relates to the field of medical tool technology, and in particular to an adaptive elastic clamping medical tube holder for placing blood collection tubes or test tubes. Background Technology

[0002] In the course of cardiovascular diagnosis and treatment, cardiology departments often need to collect blood for tests such as myocardial enzyme tests and coagulation tests. The blood collection tubes or test tubes used are usually placed on blood collection tube racks or test tube racks with slots or holes for placement and transfer. The diameters of the slots or holes in existing blood collection tube racks or test tube racks are pre-set. When dealing with blood collection tubes or test tubes of different diameters, those with diameters much smaller than the slots or holes will wobble significantly during transfer, posing a risk of tipping over or falling. At the same time, existing test tube racks cannot adjust their height according to the length of the test tubes. When longer test tubes are placed on the test tube rack, the slots or holes only limit the lower middle part of the test tube, further reducing the rack's ability to prevent tipping. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an adaptive elastic clamping medical tube rack for placing blood collection tubes or test tubes. It can provide an adaptive elastic clamping effect for blood collection tubes or test tubes of different diameters, preventing them from shaking during transfer. Furthermore, the clamping position and height are adjustable. The overall structure is simple and easy to use, facilitating the placement and transfer of blood collection tubes or test tubes of different diameters by medical personnel, and improving the safety of blood collection tubes or test tubes during placement and transfer, thus ensuring the safe management of blood samples in the cardiology department.

[0004] The technical solution of this utility model is as follows:

[0005] An adaptive elastic clamping medical tube holder includes a base and a limiting plate. The limiting plate has multiple limiting holes. The base includes a transverse seat and a longitudinal seat, with the longitudinal seat positioned on top of the transverse seat. The top of the transverse seat has multiple limiting grooves that correspond to and mate with the limiting holes. An elastic limiting component is provided on the inner circumferential surface of each limiting hole, used to elastically limit the movement of blood collection tubes or test tubes inserted into the limiting holes. A height adjustment mechanism is provided between the limiting plate and the longitudinal seat, used to adjust the height of the limiting plate relative to the base.

[0006] As a preferred embodiment of this utility model, a notch is formed on the inner circumferential surface of the lower half of the limiting hole, and the elastic limiting component is fixedly installed at the notch; during manufacturing, the elastic limiting component can be installed at the notch of the limiting hole in a modular manner.

[0007] As a preferred embodiment of the present invention, the elastic limiting component includes a block, which is fixedly installed at the notch. A groove is formed on the side of the block facing the inside of the limiting hole. A shaft is provided between the two side walls of the groove. A torsion spring is sleeved on the shaft. One end of the torsion spring abuts against the bottom of the groove, and the other end of the torsion spring is provided with a contact plate. The contact plate is used to contact the blood collection tube or test tube inserted in the limiting hole.

[0008] As a preferred embodiment of this invention, the block is interference-fitted or glued to the notch to ensure the installation stability of the elastic limiting component and prevent the elastic limiting component from falling off.

[0009] As a preferred embodiment of this invention, the contact plate is an arc-shaped structure with the inner arc surface facing upwards. When the contact plate contacts the blood collection tube or test tube, the inner arc surface of the arc-shaped contact plate fits better with the outer circumferential surface of the blood collection tube or test tube.

[0010] To ensure that the limiting groove fits into the bottom of the blood collection tube or test tube, the limiting groove is a spherical groove structure.

[0011] As a preferred embodiment of this invention, the height adjustment mechanism includes a bolt and an elastic support structure. The limiting plate has a hole through which the bolt's screw passes. The top of the longitudinal seat has a threaded hole corresponding to the hole. The bolt's screw passes through the limiting plate and is threaded into the threaded hole. A knob is provided at the nut end of the bolt. The elastic support structure is located between the limiting plate and the longitudinal seat, and it provides elastic support for the limiting plate. The bolt's exposed length is adjusted by rotating the knob. Under the elastic support of the elastic support structure, the limiting plate maintains its adjusted height, thereby adjusting the distance between the limiting plate and the base, i.e., adjusting the height of the limiting plate relative to the base, and thus adjusting the clamping height of the test tube.

[0012] As a preferred embodiment of this utility model, the hole is located on the central axis of the length direction of the limiting plate, and two elastic support structures are provided, with the two elastic support structures located on both sides of the bolt thread respectively; this is to improve the elastic support effect of the elastic support structure on the limiting plate and ensure the stability of the limiting plate under the action of elastic support.

[0013] As a preferred embodiment of this utility model, the elastic support structure includes a guide post and a spring. The guide post is disposed at the bottom of the limiting plate, and the top of the longitudinal seat is provided with a guide hole corresponding to the guide post. The guide post is inserted into the guide hole and is clearance-fitted with the guide hole. The spring is disposed between the limiting plate and the longitudinal seat and is sleeved around the guide post. The guide post and the guide hole are used to provide guidance for the limiting plate during lifting and lowering, and the spring is used to provide elastic support for the limiting plate.

[0014] To prevent the spring from deviating significantly in the vertical direction, spring limiting grooves for accommodating the ends of the spring are formed on the opposite surfaces of the limiting plate and the longitudinal seat.

[0015] The advantages of this utility model are:

[0016] When a blood collection tube or test tube is inserted into the limiting hole, the tube or test tube presses against the contact plate. At the same time, the contact plate, under the action of the torsion spring, remains in contact with the blood collection tube or test tube. With the cooperation of the limiting hole, it forms an elastic clamping effect on the blood collection tube or test tube, thus elastically restricting the movement of the blood collection tube or test tube inserted in the limiting hole. When facing blood collection tubes or test tubes of different diameters, the contact plate can also remain in contact with blood collection tubes or test tubes of different diameters under the action of the torsion spring, thereby achieving an adaptive elastic clamping effect on blood collection tubes or test tubes of different diameters, preventing the blood collection tubes or test tubes from shaking during transfer, and preventing them from tipping over or falling during placement and transfer.

[0017] The bolt's exposed length is adjusted by rotating the knob. The limiting plate maintains its adjusted position height under the elastic support of the elastic support structure, thereby adjusting the distance between the limiting plate and the base, that is, adjusting the position height of the limiting plate relative to the base, and thus adjusting the clamping position height of the test tube.

[0018] The overall structure is simple and easy to use, which helps medical staff to place and transfer blood collection tubes or test tubes of different diameters, and improves the safety of blood collection tubes or test tubes during placement and transfer, ensuring the safe management of blood samples in the cardiology department.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0034] As shown in Figures 1-6, this embodiment is an adaptive elastic clamping medical tube holder, including a plastic base 1 and a limiting plate 2. The limiting plate 2 has multiple limiting holes 3. The base 1 includes a transverse seat 11 and a longitudinal seat 12. The longitudinal seat 12 is located at the top of one end of the transverse seat 11. The transverse seat 11 and the longitudinal seat 12 are an integral structure. Multiple limiting grooves 4 corresponding to and cooperating with the limiting holes 3 are formed on the top of the transverse seat 11. To ensure that the limiting grooves 4 cooperate with the bottom of the blood collection tubes or test tubes 5, the limiting grooves 4 in this embodiment are spherical groove structures. An elastic limiting component is provided on the inner circumferential surface of the limiting hole 3. The elastic limiting component is used to elastically limit the movement of the blood collection tubes or test tubes 5 inserted in the limiting hole 3. A height adjustment mechanism is provided between the limiting plate 2 and the longitudinal seat 12. The height adjustment mechanism is used to adjust the position height of the limiting plate 2 relative to the base 1.

[0035] As shown in Figures 5-8, in this embodiment, a notch 30 is formed on the inner circumferential surface of the lower half of the limiting hole 3, and the elastic limiting component is fixedly installed at the notch 30. During manufacturing, the elastic limiting component can be installed at the notch 30 of the limiting hole 3 in a modular manner. The elastic limiting component includes a block 21, which is fixedly installed at the notch 30 by interference fit. In practical applications, the block 21 can also be fixedly installed at the notch 30 by adhesive to ensure the installation stability of the elastic limiting component and prevent the elastic limiting component from falling off. The block 21 faces... A groove 22 is formed inside the limiting hole 3. A shaft 23 is provided between the two side walls of the groove 22. A torsion spring 24 is sleeved on the shaft 23. One end of the torsion spring 24 abuts against the bottom of the groove 22. The other end of the torsion spring 24 is provided with a contact plate 25. The contact plate 25 is used to contact the blood collection tube or test tube 5 inserted in the limiting hole 3. As shown in Figure 9, the contact plate 25 in this embodiment is an arc-shaped structure with the inner arc surface facing upward. When the contact plate 25 contacts the blood collection tube or test tube 5, the inner arc surface of the arc-shaped contact plate 25 fits better with the outer circumferential surface of the blood collection tube or test tube 5.

[0036] As shown in Figures 2-4, the height adjustment mechanism in this embodiment includes a bolt 31 and an elastic support structure. A hole 20 is formed on the limiting plate 2 for the bolt 31 to pass through. A threaded hole 13 corresponding to the hole 20 is formed on the top of the longitudinal seat 12. After the bolt 31 passes through the limiting plate 2, it is threaded into the threaded hole 13. A knob 32 is provided at the nut end of the bolt 31. The knob 32 is made of plastic, and the nut end of the bolt 31 is embedded inside the knob 32. The outer circumferential surface of the knob 32 has an anti-slip textured structure (not shown in the figure). The elastic support structure is located between the limiting plate 2 and the longitudinal seat 12, and is used to elastically support the limiting plate 2. By rotating the bolt 31 with the knob 32, the exposed length of the bolt 31 is adjusted. Under the elastic support of the elastic support structure, the limiting plate 2 maintains its adjusted position height, thereby achieving the distance adjustment between the limiting plate 2 and the base 1, that is, the position height adjustment of the limiting plate 2 relative to the base 1, and thus achieving the height adjustment of the clamping position of the test tube.

[0037] As shown in Figures 2-4, in this embodiment, the hole 20 is located on the central axis of the length direction of the limiting plate 2. Two elastic support structures are provided, located on both sides of the bolt 31. This is to improve the elastic support effect of the elastic support structure on the limiting plate 2 and ensure the stability of the limiting plate 2 under elastic support. The elastic support structure includes a guide post 33 and a spring 34. The guide post 33 is located at the bottom of the limiting plate 2, and the top of the longitudinal seat 12 is provided with a guide hole 14 corresponding to the guide post 33. The guide post 33 is inserted into the guide hole 14. The guide post 33 is fitted into the guide hole 14 with a clearance fit, so that the guide post 33 can slide up and down in the guide hole 14. The spring 34 is disposed between the limiting plate 2 and the longitudinal seat 12 and sleeved around the guide post 33. The guide post 33 and the guide hole 14 are used to provide guidance for the limiting plate 2 during lifting and lowering, and the spring 34 is used to provide elastic support for the limiting plate 2. In order to prevent the spring 34 from deviating too much in the vertical direction, spring limiting grooves 35 are formed on the opposite surfaces of the limiting plate 2 and the longitudinal seat 12 to accommodate the end of the spring 34.

[0038] When the blood collection tube or test tube 5 is inserted into the limiting hole 3, the blood collection tube or test tube 5 presses against the contact plate 25. At the same time, under the action of the torsion spring 24, the contact plate 25 is always in contact with the blood collection tube or test tube 5, and with the cooperation of the limiting hole 3, it forms an elastic clamping effect on the blood collection tube or test tube 5, thereby elastically restricting the movement of the blood collection tube or test tube 5 inserted in the limiting hole 3, as shown in Figure 6. When facing blood collection tubes or test tubes 5 with different diameters, under the action of the torsion spring 24, the contact plate 25 can also always be in contact with blood collection tubes or test tubes 5 with different diameters, thereby achieving an adaptive elastic clamping effect on blood collection tubes or test tubes 5 with different diameters, avoiding shaking of the blood collection tubes or test tubes 5 during transfer, and preventing the blood collection tubes or test tubes 5 from tipping over or falling during placement and transfer. When taking out the blood collection tube or test tube 5, the blood collection tube or test tube 5 can be taken out from the limiting hole 3 by appropriately pressing the contact plate 25 while pulling upward.

[0039] The exposed length of the bolt 31 is adjusted by rotating the knob 32. The limiting plate 2 maintains the adjusted position height under the elastic support of the elastic support structure, thereby realizing the distance adjustment between the limiting plate 2 and the base 1, that is, the position height adjustment of the limiting plate 2 relative to the base 1, and thus realizing the adjustment of the clamping position height of the test tube.

[0040] This embodiment has a simple overall structure and is easy to use. It facilitates the placement and transfer of blood collection tubes or test tubes of different diameters by medical staff, and improves the safety of blood collection tubes or test tubes during placement and transfer, thus ensuring the safe management of blood samples in the cardiology department.
