Description

Technical Field

[0001] The invention relates to the technical field of internal medicine nursing puncture equipment, in particular to a cardiovascular internal medicine nursing puncture device. Background Art

[0002] Puncture is a diagnostic and treatment technique in which a needle is inserted into the body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for imaging examination, or inject medicine into the body cavity. This operation has the advantages of less trauma, quick recovery, and definite efficacy, and is widely used in clinical practice.

[0003] When performing cardiovascular puncture on a patient, the puncture is performed from the patient's arm. However, the patient may move his arm during the puncture, making it difficult for the puncture needle to accurately enter the target blood vessel. After the puncture needle enters the blood vessel in the arm, the movement of the arm may cause the puncture needle to move in the blood vessel or pass out of the blood vessel, causing vascular damage, thereby increasing the patient's pain and risk of infection. Summary of the invention

[0004] The purpose of the present invention is to provide a cardiovascular care puncture device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a cardiovascular internal medicine nursing puncture device, comprising a base, the top surface of the base is an arc-shaped depression, grooves are provided on both sides of the base, the inner walls of the two grooves are fixedly connected with slide rails, and the top of the base is fixedly connected with a bracket:

[0007] The top of the base is provided with an arc groove, the inner wall of the arc groove is provided with a fixing assembly, the fixing assembly includes a fixing frame fixedly connected to the inner wall of the arc groove, the side wall of the fixing frame is provided with a plurality of sliding grooves, the inner walls of a plurality of the sliding grooves are slidably connected with sliding rods, a plurality of the sliding rods are fixedly connected with push blocks on the side away from the fixing frame, a plurality of the push blocks are fixedly connected with a limiting rod on the side away from the sliding rod, the inner wall of the fixing frame is provided with an annular groove, the inner wall of the annular groove is rotatably connected with a swivel, the side wall of the swivel is provided with a plurality of limiting grooves, and the inner walls of a plurality of the limiting grooves are slidably connected with the outer surface of the limiting rod.

[0008] Furthermore, a placement groove is provided inside the push block, the inner wall of the placement groove is slidably connected with a connecting block, the end of the connecting block away from the push block is fixedly connected with a pressure plate, the end of the connecting block away from the pressure plate is fixedly connected with a spring 1, and the end of the spring 1 away from the connecting block is fixedly connected to the inner wall of the placement groove.

[0009] Furthermore, a support plate is fixedly connected to the outer surface of the swivel, a motor is fixedly connected to the side of the support plate away from the base, a gear is fixedly connected to the output end of the motor, and the side of the gear close to the swivel is meshed with the side wall of the swivel.

[0010] Furthermore, a scanning assembly is arranged between the bracket and the fixed frame, and the scanning assembly includes a movable frame slidably connected to the outer surface of the slide rail.

[0011] Furthermore, a support rod is fixedly connected to the top of the movable frame, and two movable blocks are slidably connected to the outer surface of the support rod, and the two movable blocks are symmetrically arranged.

[0012] Furthermore, one side of the two moving blocks away from each other is fixedly connected with a spring 2, and the two springs 2 are both sleeved on the outer surface of the support rod, and one end of the two springs 2 away from the moving blocks is respectively fixedly connected to the inner wall of the moving frame.

[0013] Furthermore, one side of the two moving blocks close to the base is rotatably connected to a connecting rod, and one end of the two connecting rods away from the moving blocks is rotatably connected to a moving plate.

[0014] Furthermore, a detector is provided on the outer surface of the movable plate, and a side of the movable plate close to the base is rotatably connected to two rollers.

[0015] The present invention has the following beneficial effects:

[0016] (1) In the present invention, the swivel rotates, and a limit groove is provided on the side wall of the swivel, and a limit rod is placed inside the limit groove. Therefore, when the swivel rotates, the push block is driven to rotate synchronously through the limit rod. Since the push block slides on the inner wall of the slide groove through the slide rod, when the push block is driven to rotate by the swivel, the push block will move toward the center of the fixed frame along the trajectory of the slide groove, thereby fixing the arm.

[0017] (2) In the present invention, when the push block moves toward the arm, a pressure plate is arranged at the end of the push block to contact the arm. As the push block continues to be pushed, the pressure plate squeezes the spring 1 through the connecting block. The spring 1 generates elastic force after being squeezed. The elastic force generated by the spring 1 can serve as a buffer effect to reduce the patient's discomfort. The pressure plate can replace the transmission compression cuff to provide appropriate pressure to the proximal end of the arm, pressurize the puncture site, help stop bleeding and reduce bleeding, thereby providing convenience for medical personnel.

[0018] (3) In the present invention, the movable plate drives the movable blocks on both sides to slide on the surface of the support rod through the connecting rod. The side walls of the movable blocks on both sides are supported by springs, so that the movable plate can continuously fit on the surface of the arm. This fit ensures the stability of the detector when collecting data. When the movable plate moves, it drives the rollers on both sides on the surface of the arm. The rollers can not only reduce the friction between the movable plate and the arm when it moves, but also the surface of the rollers is coated with disinfectant alcohol. When it comes into contact with the arm, it can disinfect the epidermis of the arm. The medical staff starts puncture according to the blood vessel position displayed by the detector.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 As shown, the present invention is a cardiovascular internal medicine nursing puncture device, comprising a base 1, the top surface of the base 1 is an arc-shaped depression, grooves 101 are provided on both sides of the base 1, the inner walls of the two grooves 101 are fixedly connected with slide rails 102, and the top of the base 1 is fixedly connected with a bracket 103:

[0032] An arc groove is provided on the top of the base 1, and a fixing assembly 2 is provided on the inner wall of the arc groove. The fixing assembly 2 includes a fixing frame 201 fixedly connected to the inner wall of the arc groove, a plurality of slide grooves 206 are provided on the side wall of the fixing frame 201, and the inner walls of the plurality of slide grooves 206 are slidably connected with slide rods 205, and a plurality of slide rods 205 are fixedly connected with push blocks 204 on the side away from the fixing frame 201, and a plurality of push blocks 204 are fixedly connected with a limiting rod 203 on the side away from the slide rod 205, and an annular groove 207 is provided on the inner wall of the fixing frame 201, and a swivel 202 is rotatably connected to the inner wall of the annular groove 207, and a plurality of limiting grooves 208 are provided on the side wall of the swivel 202, and a plurality of limiting grooves 20 The inner walls of 8 are slidably connected with the outer surface of the limiting rod 203. When the swivel 202 rotates, a limiting groove 208 is provided on the side wall of the swivel 202, and a limiting rod 203 is placed inside the limiting groove 208. Therefore, when the swivel 202 rotates, the push block 204 will be driven to rotate synchronously through the limiting rod 203. Since the push block 204 slides on the inner wall of the slide groove 206 through the slide rod 205, when the push block 204 is driven to rotate by the swivel 202, the push block will move along the trajectory of the slide groove 206 toward the center of the fixed frame 201, thereby fixing the arm. The fixed arm can ensure that the puncture site remains stable during the operation and reduce the puncture position deviation caused by the movement of the arm.

[0033] The push block 204 is provided with a placement groove 304, and the inner wall of the placement groove 304 is slidably connected with a connecting block 302, and the end of the connecting block 302 away from the push block 204 is fixedly connected to a pressure plate 301, and the end of the connecting block 302 away from the pressure plate 301 is fixedly connected to a spring 303, and the end of the spring 303 away from the connecting block 302 is fixedly connected to the inner wall of the placement groove 304, and a pressure plate 301 is set at the end of the push block 204 to contact the arm, and as the push block 204 continues to push, the pressure plate 301 squeezes the spring 303 through the connecting block 302, and the spring 303 generates elastic force after being squeezed. The elastic force generated by the spring 303 can serve as a buffer effect to reduce the patient's discomfort, and the pressure plate 301 can replace the transmitted compression belt to provide appropriate pressure to the proximal end of the arm, pressurize the puncture site, help stop bleeding and reduce bleeding, thereby providing convenience for medical staff.

[0034] The outer surface of the rotating ring 202 is fixedly connected to a support plate 401, a side of the support plate 401 away from the base 1 is fixedly connected to a motor 402, an output end of the motor 402 is fixedly connected to a gear 403, and a side of the gear 403 close to the rotating ring 202 is meshed with the side wall of the rotating ring 202.

[0035] A scanning assembly 5 is arranged between the bracket 103 and the fixed frame 201. The scanning assembly 5 includes a moving frame 501 slidably connected to the outer surface of the slide rail 102. A support rod 502 is fixedly connected to the top of the moving frame 501. Two moving blocks 503 are slidably connected to the outer surface of the support rod 502. The two moving blocks 503 are symmetrically arranged. The support rod 502 provides a moving trajectory for the movement of the moving blocks 503, so that the moving blocks 503 remain at the same level when moving.

[0036] The two moving blocks 503 are fixedly connected to the sides away from each other with spring 2 504, and the two spring 2 504 are both sleeved on the outer surface of the support rod 502. The ends of the two spring 2 504 away from the moving block 503 are respectively fixedly connected to the inner wall of the moving frame 501. The spring 2 504 not only provides support for the moving block 503, but also can reset the moving block 503 after moving.

[0037] The two moving blocks 503 are rotatably connected to the side close to the base 1 with a connecting rod 505, and the two connecting rods 505 are rotatably connected to the moving plate 506 at one end away from the moving block 503. The outer surface of the moving plate 506 is provided with a detector 507. The moving plate 506 can continuously fit on the surface of the arm. This fit ensures the stability of the detector 507 when collecting data. The moving plate 506 is rotatably connected to the side close to the base 1 with two rollers 508. The wheels 508 can not only reduce the friction between the moving plate 506 and the arm when moving, but also the surface of the roller 508 is coated with disinfectant alcohol, which can disinfect the epidermis of the arm when in contact with the arm.

[0038] When in use, the patient inserts his arm from the center of the fixing frame 201 and places it on the top surface of the base 1, then starts the motor 402 to drive the gear 403 to rotate counterclockwise through the transmission shaft, and as the gear 403 rotates, the rotating ring 202 is driven to rotate. A limiting groove 208 is provided on the side wall of the rotating ring 202, and a limiting rod 203 is placed inside the limiting groove 208. Therefore, when the rotating ring 202 rotates, the pushing block 204 will be driven to rotate synchronously through the limiting rod 203. Since the pushing block 204 slides on the inner wall of the sliding groove 206 through the sliding rod 205, when the pushing block 204 is driven to rotate by the rotating ring 202, the pushing block will move along the trajectory of the sliding groove 206 to the center of the fixing frame 201, thereby fixing the arm. Fixing the arm can ensure that the puncture site remains stable during the operation and reduce the deviation of the puncture position caused by the movement of the arm.

[0039] When the push block 204 moves toward the arm, a pressure plate 301 is provided at the end of the push block 204 to contact the arm. As the push block 204 continues to push, the pressure plate 301 squeezes the spring 303 through the connecting block 302. The spring 303 generates elastic force after being squeezed. The elastic force generated by the spring 303 can serve as a buffer effect to reduce the patient's discomfort. The pressure plate 301 can replace the transmitted compression cuff to provide appropriate pressure to the proximal end of the arm, pressurize the puncture site, help stop bleeding and reduce bleeding, thereby providing convenience for medical staff.

[0040] After the proximal end of the arm is fixed, the mobile frame 501 slides on the outer surface of the slide rail 102, and the mobile frame 501 drives the bottom mobile plate 506 to slide on the surface of the arm. The surface of the mobile plate 506 is provided with a detector 507, wherein the model of the detector 507 is a Doppler blood flow detector probe TK10M3S8AF. The detector 507 can clearly display the position and direction of the blood vessels on the arm, so that the medical staff can accurately select the best puncture point. Since the surface of the arm is not flat, the mobile plate 506 will float up and down while in contact with the arm, and the mobile plate 506 will drive the connecting rod 505 to move. The moving blocks 503 on both sides slide on the surface of the support rod 502, and the side walls of the moving blocks 503 on both sides are supported by springs 504, so the moving plate 506 can continuously fit on the surface of the arm. This fit ensures the stability of the detector 507 when collecting data. When the moving plate 506 moves, it will drive the rollers 508 on both sides on the surface of the arm. The rollers 508 can not only reduce the friction between the moving plate 506 and the arm when moving, but also the surface of the rollers 508 is coated with disinfectant alcohol. When in contact with the arm, the epidermis of the arm can be disinfected. The medical staff starts puncture according to the blood vessel position displayed by the detector 507.
