[0077] 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. It should be noted that, for ease of description, in this application, "left side" is referred to as "first end", "right side" as "second end", "upper side" as "first end", and "lower side" as "second end" in the current view. The purpose of such description is to clearly express the technical solution and should not be construed as an improper limitation of the technical solution of this application.

[0078] The purpose of this utility model is to provide an adjustable chairside blood drawing operating table structure that can flexibly adjust its height and angle according to the patient's position and operational needs, providing stable support and a convenient operating environment. Specifically, this adjustable chairside blood drawing operating table structure can be placed next to a dental chair and includes:

[0079] The control panel 1 and the folding mechanism 10 enable the control panel 1 to be unfolded into a first panel 101 and a second panel 102, with a reserved gap area 103 between the first panel 101 and the second panel 102.

[0080] The operating panel 1 can be used for patient arm support. After the folding mechanism 10 is used for standing, the first panel 101 and the second panel 102 can be unfolded to a greater extent. The angle adjustment mechanism 20 is fixedly connected to the second panel 102 so that the second panel 102 can be tilted at a preset angle or placed on a plane, allowing the patient to choose a more suitable posture.

[0081] The height adjustment mechanism 30 is connected to the angle adjustment mechanism 20 and is used to adjust the working height of the angle adjustment mechanism 20. The height adjustment mechanism 30 is connected to a base 2.

[0082] In summary, in this technical solution, the height and angle of the actual operating panel 1 are adjustable. The operating panel 1 can be flexibly adjusted in height and angle according to the patient's position and the nurse's operating needs, thereby improving the ease of operation.

[0083] In addition, this technical solution also uses a storage tray 303 for convenient placement of items, and the storage tray 303 is also a system fixing component for the central support 301 and auxiliary support 302, making the base 2 more stable. The storage slot 304 contains items, which makes it convenient for nurses to place and retrieve blood collection items, improves operational efficiency, and enhances overall stability. Furthermore, the bottom of the base 2 can be designed with anti-slip features to further ensure stability during use and prevent shaking.

[0084] Therefore, this design can also solve the problems of not having a suitable place to put items before blood drawing, inconvenience for nurses to operate, and not having a container to hold the needle after blood drawing.

[0085] In one specific embodiment, please refer to the appendix. Figure 4 As shown, the two sides of the horizontal plate 102a can be connected to the side of a second panel 102 respectively; the two sides of the folding and flipping plate 101b can be connected to the side of a first panel 101 respectively. In this scheme, the preferred configuration of the length of the two panels is 40cm and the width is 15cm. The folding mechanism has high stability and can have a larger unfolding range.

[0086] A reserved gap area 103 is formed between the first panel 101 and the second panel 102. The reserved gap area 103 is designed to accommodate a folding mechanism and also makes it easier to apply a tourniquet.

[0087] In addition, the operating surfaces of the first panel 101 and the second panel 102 are made of silicone material with a thickness of 2mm to increase friction and prevent slippage.

[0088] In one specific embodiment, please refer to the appendix. Figure 2 , 3 As shown in Figures 5 and 6, the folding mechanism 10 includes:

[0089] The basic triangular base 11 forms a hollow region 11a. The basic triangular base 11 is equivalent to being composed of two sets of clips and has a connecting base plate 11b.

[0090] A horizontal plate 102a is fixedly connected to one side of the base triangular base 11, forming a fixed connection with the clamping piece of the base triangular base 11, as shown in the attached figure. Figure 5 As shown;

[0091] The folding and flipping plate 101b is connected to the other side of the base triangular seat 11 via a hinge mechanism;

[0092] In a horizontal position, the horizontal plate 102a and the folding / flipping plate 101b are located on the same plane, as shown in the attached figure. Figure 2 As shown in the middle state;

[0093] The folding and flipping panel 101b can be folded over the horizontal panel 102a via a hinge mechanism, as shown in the attached diagram. Figure 3 As shown,

[0094] This solution requires a stable hinge mechanism to ensure the unfolding and folding of the folding flip plate 101b and the horizontal plate 102a. Therefore, this hinge mechanism also includes:

[0095] The stabilizing rod 12 has its second end rotatably connected to the first rotation point A of the base triangular seat 11, and its first end is at the second rotation point B.

[0096] The first traction component 14 is constructed in the shape of an obtuse triangle, and the smallest acute angle end of the first traction component 14 is rotatably connected to one end of the stabilizing wall rod 12 (corresponding to the second rotation point B).

[0097] Please refer to the appendix. Figure 2 , 3 As shown, the stabilizing rod 12 rotates very little at the first rotation point A, from the attached Figure 2 To the attached Figure 3 A 30-degree angle of movement is sufficient to ensure effective and stable traction.

[0098] Specifically, the triangular rotating component 13 is constructed in the shape of a right triangle and is arranged in the hollow region 11a; the folding and flipping plate 101b is fixedly connected to the triangular rotating component 13.

[0099] The other acute-angled end of the first traction component 14 is rotatably connected to the end of the triangular rotating component 13 away from the folding and flipping plate 101b (corresponding to the third rotation point C).

[0100] As attached Figure 6 As shown, it also includes: a main action triangle 15, which is constructed as an equilateral right triangle. One acute angle end of the main action triangle 15 is rotatably connected to the vertex position of the base triangle 11, and the other acute angle end of the main action triangle 15 is rotatably connected to one end of the stabilizing link 16. The other end of the stabilizing link 16 is rotatably connected to the tangent side of the triangular rotating member 13, thus completing the configuration of a stable hinge.

[0101] In one specific embodiment, please refer to the appendix. Figure 1 , 7 As shown in Figure 8, in order to achieve the angle adjustment function within a certain range and to ensure the stability of the operating panel 1, the angle adjustment mechanism 20 in this solution is designed as follows: it includes an angle support plate 21, the first surface of which is connected to the lower end of the second panel 102.

[0102] One end of the foundation support 22 is rotatably connected to one end of the angle support plate 21 via a rotating component 23. The rotating component 23 is attached to the... Figure 8 There are two sets in the middle, which are set on both sides of the foundation support 22 to avoid affecting the configuration of the lead screw shaft support 27;

[0103] A stabilizing block 231 is provided below the angle support plate 21;

[0104] The actuating handle 24 has one end rotatably connected to the stabilizing block 231 and the other end rotatably connected to a moving block 25, which is connected to a lead screw shaft 26. Two sets of lead screw shaft supports 27 are provided on the base support 22. The lead screw shaft 26 is rotatably connected to the lead screw shaft support 27. One end of the lead screw shaft 26 passes through the base support 22 and connects to a knob 28. In order to facilitate quick and easy angle adjustment while ensuring stability, this solution adjusts the knob 28 to move the moving block 25 on the lead screw shaft 26. By changing the position of the moving block 25, the actuating handle 24 drives the stabilizing block 231, thereby allowing the angle support plate 21 to tilt, so as to achieve the final angle adjustment.

[0105] In one specific embodiment, the height adjustment mechanism 30, please refer to the appendix. Figure 1 As shown, since dental chairs generally have adjustable height, even if the size of the dental chair is not adjustable, the height of different sizes of dental chairs can vary significantly. Therefore, in this solution, the height adjustment mechanism 30 only needs to ensure adjustment for patient comfort, with the main support pillow providing greater stability, without requiring large-scale height adjustments. Specific configurations include:

[0106] The main support platform 31 has a guide sleeve 32 at its center on its first side. Two sets of electric cylinders 320 are arranged on both sides of the main support platform 31, with the fixed ends of the electric cylinders 320 fixed to the main support platform 31. The output ends of the two sets of electric cylinders 320 are fixedly connected to a connecting plate 33. The upper part of the connecting plate 33 is fixedly connected to the foundation support 22 via a connector 34. A guide rod 35 is connected to the lower part of the connecting plate 33. The guide rod 35 can be inserted into the guide hole 32a of the guide sleeve 32. When the two sets of electric cylinders 320 rise or fall synchronously, the guide rod 35 is used to cooperate with the guide hole 32a of the guide sleeve 32 to complete the guidance. In the actual configuration:

[0107] The guide rod 35 can be made of aluminum alloy, and its height can be adjusted between 30cm and 55cm.

[0108] In one specific embodiment, please refer to the appendix. Figure 1 , 9 As shown, the base 2 and the main support platform 31 are fixedly connected by a central pillar 301; it also includes: multiple auxiliary pillars 302 connected to the base 2 and the main support platform 31; the multiple auxiliary pillars 302 are arranged around the central pillar 301; a storage tray 303 is arranged between the base 2 and the main support platform 31 and is fixedly connected to the central pillar 301 and the auxiliary pillars 302; the first side of the storage tray 303 has multiple storage slots 304, which can be used to place small sharp objects to increase convenience.

[0109] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
