Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to a blood collection fixation table. Background Technology

[0002] Blood collection is a common laboratory test in medical institutions and one of the most basic operational techniques in nursing work. When collecting blood from children, in order to avoid children's fear and resistance, which would cause inconvenience to the blood collection process, a blood collection station is often used. The blood collection station can block the child's view to reduce the child's fear during blood collection, and at the same time, it can clamp and fix the child's arm, thereby overcoming the difficulties caused by the child's resistance to the blood collection process.

[0003] Based on the above, the existing blood collection fixation device has a fixed clamping force on the child's arm that cannot be adjusted. If the clamping pressure is too small, the blood vessels in the arm cannot be highlighted, making it difficult for staff to find the blood vessels and insert the blood collection needle. If the pressure is too large, it hinders the normal flow of blood in the arm, limiting the amount of blood collected, which is also not conducive to the blood collection work. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a blood collection fixation table to solve the problem of uncontrollable clamping force on the arm in existing blood collection fixation tables.

[0005] This utility model provides a blood collection fixation table, which is achieved by the following specific technical means:

[0006] A blood collection station includes a base plate; the base plate is rectangular, and a support plate is supported below the base plate. An upward-moving electric telescopic rod is set at the center of the base plate. The upper end of the electric telescopic rod is fixedly connected to a worktable of the same size as the base plate. Two sets of fixed plates are set on the worktable, and a slide rail is fixedly connected between the fixed plates. Two sets of clamping mechanisms are set on the slide rail. The clamping mechanism includes a slider, which is slidably connected to the slide rail. A limiting ring is fixedly connected above the slider through a connecting column. An annular airbag is placed inside the limiting ring. Pressure sensors are embedded in the inner side of the annular airbag. An air pump is connected to the outer side of the annular airbag through an air supply pipe. A shut-off valve is set at the end of the air supply pipe near the air pump. The air pump is fixedly installed on the worktable. A vertically placed shield is set on one side of the worktable. One side of the shield is fixedly supported on the worktable by a fixing rod. An access port is opened on the shield. An elastic ring is set inside the access port, and the center of the elastic ring and the center of the two sets of limiting rings are on the same axis.

[0007] Furthermore, bushings are provided near the four corner edges of the base plate, and guide rods slide through the bushings, with the upper ends of the guide rods fixedly connected to the worktable.

[0008] Furthermore, the slide rail has multiple pin holes at equal intervals, and the slider of the clamping mechanism also has pin holes. The pin holes on the two sliders are each aligned with a pin hole on the slide rail, and a positioning pin is inserted therein.

[0009] Furthermore, the shut-off valve is connected to a controller via a control line. The controller is fixedly mounted on a workbench and has a display screen and control panel.

[0010] Furthermore, a light is connected to the workbench via a connecting hose, and the light shines directly onto the slide rail.

[0011] Furthermore, a notch is provided on the bottom plate near the slide rail, which separates the lower support plate into two parts.

[0012] Furthermore, a square test tube box is fixed on the base plate, a test tube rack is fixed inside the test tube box, and blood collection tubes are placed in the test tube rack; a square clearance hole is opened on the worktable above the test tube box, and the size of the clearance hole is larger than the cross-sectional size of the test tube box.

[0013] Furthermore, drawer slots are provided between the support plates, and a storage drawer is slidably connected in the drawer slots. A drawer pull-out opening is provided on one side of the support plate.

[0014] Furthermore, a square storage slot is provided on the base plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model features an electric telescopic rod that adjusts the height of the worktable and a guide rod that keeps the worktable in a horizontal position, ensuring that the height of the worktable is suitable for children and that children are in the most comfortable sitting position when having their blood drawn.

[0017] 2. This utility model, by setting up a slide rail and a clamping mechanism, adjusts the positions of the two sets of clamping mechanisms on the slide rail to adapt the clamping mechanism to the length of a child's arm. After the annular airbag is inflated, it clamps the child's arm. Once clamped, the arm cannot be pulled out before the annular airbag is deflated. This ensures the smooth progress of blood collection.

[0018] 3. This utility model, by setting up an annular airbag, pressure sensor, shut-off valve and controller, turns on the air pump to input pressurized gas into the annular airbag through the air supply pipe. The annular airbag clamps the arm. The shut-off valve is controlled by the controller. With the cooperation of two sets of pressure sensors, the pressure caused by the annular airbag clamping the arm can be adjusted. This can make the blood vessels stand out without affecting the blood flow, thereby improving the conditions for blood collection by adjusting the pressure.

[0019] 4. This utility model features a storage drawer and a storage slot, with a square storage slot on the bottom plate. The storage drawer can hold medical instruments used for blood collection. Before blood collection, the necessary medical instruments can be taken out of the storage drawer and placed in the storage slot, making them convenient to use and improving blood collection efficiency.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 6 As shown:

[0031] This utility model provides a blood collection station, including a base plate 1; the base plate 1 is rectangular, and a support plate 6 is supported below the base plate 1. An upward-moving electric telescopic rod 2 is set at the center of the base plate 1. The upper end of the electric telescopic rod 2 is fixedly connected to a worktable 3 of the same size as the base plate 1. Two sets of fixing plates 7 are set on the worktable 3, and a slide rail 8 is fixedly connected between the fixing plates 7. Two sets of clamping mechanisms are set on the slide rail 8. The clamping mechanism includes a slider 10, which is slidably connected to the slide rail 8. A limiting ring 13 is fixedly connected above the slider 10 through a connecting post 12. A limiting ring 13 is placed inside the limiting ring 13. There is an annular airbag 14, with pressure sensors 15 embedded on the inner side of the annular airbag 14. The outer side of the annular airbag 14 is connected to an air pump 17 through an air supply pipe 16. A shut-off valve 18 is provided at one end of the air supply pipe 16 near the air pump 17. The air pump 17 is fixedly installed on the workbench 3. A vertically placed baffle 21 is provided on one side of the workbench 3. One side of the baffle 21 is fixedly supported on the workbench 3 by a fixing rod 24. An extension port 22 is opened on the baffle 21. An elastic ring 23 is provided inside the extension port 22, and the center of the elastic ring 23 is on the same axis as the center of the two sets of limiting rings 13.

[0032] Among them, such as Figure 3 As shown, bushings 4 are provided near the four corner edges of the base plate 1. Guide rods 5 slide through the bushings 4, and the upper end of the guide rods 5 is fixedly connected to the worktable 3. The height of the worktable 3 is adjusted by the electric telescopic rod 2, and the guide rods 5 help to limit the worktable 3 to a horizontal state, so that the height of the worktable 3 is adapted to the height of the child, thereby ensuring that the child is in the most comfortable sitting position when collecting blood.

[0033] Among them, such as Figure 1 As shown, multiple pin holes 9 are evenly spaced on the slide rail 8, and pin holes 9 are also provided on the slider 10 of the clamping mechanism. The pin holes 9 on the two sliders 10 are each aligned with a pin hole 9 on the slide rail 8, and a positioning pin 11 is inserted. The positions of the two clamping mechanisms on the slide rail 8 are adjusted so that the position of the clamping mechanism is adapted to the length of the child's arm. After the annular airbag 14 is filled with gas, the child's arm is clamped. The arm cannot be pulled out before the annular airbag 14 is deflated, thus ensuring the smooth progress of blood collection.

[0034] Among them, such as Figure 6 As shown, the shut-off valve 18 is connected to the controller 20 via the control line 19. The controller 20 is fixedly installed on the workbench 3 and has a display screen and control panel. After the clamping mechanism clamps the child's arm, it controls the shut-off valve 18 through the controller 20 and works with two sets of pressure sensors 15 to adjust the pressure caused by the annular airbag 14 when clamping the arm. This avoids obstructing blood flow due to excessive pressure or making blood vessels difficult to protrude due to insufficient pressure, thereby improving the conditions for blood collection by adjusting the pressure.

[0035] Among them, such as Figure 2As shown, a light 26 is connected to the workbench 3 via a connecting hose 25. The light 26 is directed towards the slide rail 8. Adjusting the connecting hose 25 allows the light 26 to illuminate the arm, making the blood vessels more prominent and facilitating the insertion of the needle into the blood vessel for blood collection.

[0036] Among them, such as Figure 1 As shown, a notch 27 is provided on the side of the base plate 1 near the slide rail 8. The notch 27 separates the support plate 6 below into two parts. The notch 27 is provided to give the staff enough space to accommodate their legs when they are collecting blood.

[0037] Among them, such as Figure 1 As shown, a square test tube box 28 is fixed on the base plate 1, and a test tube rack 29 is fixed inside the test tube box 28. Blood collection tubes 30 are placed inside the test tube rack 29. A square clearance hole 31 is provided on the workbench 3 directly above the test tube box 28, and the size of the clearance hole 31 is larger than the cross-sectional size of the test tube box 28. After blood collection is completed, the blood collection tubes 30 containing the blood samples can be placed on the test tube rack 29 inside the test tube box 28 for easy sorting of blood samples. The clearance hole 31 on the workbench 3 prevents the blood collection tubes 30 inside the test tube box 28 from being crushed when adjusting the height of the workbench 3.

[0038] Among them, such as Figure 1 As shown, a drawer slot 32 is provided between the support plates 6, and a storage drawer 33 is slidably connected in the drawer slot 32. A drawer pull-out opening is provided on one side of the support plate 6; a square storage slot 34 is provided on the bottom plate 1; the storage drawer 33 can be used to store medical instruments for blood collection. Before blood collection, the medical instruments to be used can be taken out from the storage drawer 33 and placed in the storage slot 34 for convenient use.

[0039] The specific usage and function of this embodiment are as follows:

[0040] In this invention, the height of the worktable is adjusted according to the child's height using an electric telescopic rod 2. The child sits behind the shield 21 and inserts the arm to be blood-collected into the inlet 22 of the shield 21. The arm is simply fixed by the elastic ring 23 inside the inlet 22. The position of the clamping mechanism on the slide rail 8 is adjusted according to the length of the child's arm and fixed by the positioning pin 11. The arm passes through the limiting rings 13 of the two clamping mechanisms. The air pump 17 is turned on and pressurized gas is introduced into the annular airbag 14 through the air supply pipe 16. The annular airbag 14 clamps the arm. The controller 20 controls the shut-off valve 18 and, in conjunction with two sets of pressure sensors 15, adjusts the pressure caused by the annular airbag 14 clamping the arm, making the blood vessels prominent without affecting blood flow. The connecting hose 25 is adjusted, and the blood collection site on the arm is illuminated by the lighting lamp 26. Blood collection is then performed.
