Description

Technical Field

[0001] This utility model relates to the field of vascular imaging auxiliary equipment, and in particular to an infrared vascular image enhancement device. Background Technology

[0002] As a medical device that assists medical staff in puncturing patients' veins, the vascular imaging instrument utilizes the characteristic that hemoglobin in the blood absorbs near-infrared light more strongly than other tissues. By projecting near-infrared light of a specific wavelength onto the skin surface, photosensitive components collect infrared images of the skin and process them to obtain a vascular distribution contour map. The image is then projected onto the skin surface to display the thickness, direction, distribution, and contour of the blood vessels, making it easier for medical staff to locate the blood vessels for puncture.

[0003] In actual puncture procedures, the imaging capabilities of vascular imaging devices are limited, often failing to penetrate obese patients. Therefore, image intensification devices are typically needed to enhance the clarity of vascular visualization. For example, an infrared vascular image intensification device (publication number CN215899630U) disclosed on the Chinese Patent Network uses a movable block on a base to hold the patient's arm. The number of rows of near-infrared lamps activated is selected based on the actual size of the patient's arm; the larger the diameter of the patient's arm, the more rows of near-infrared lamps are activated. This increases the amount of near-infrared light projected onto the patient's skin surface, preventing near-infrared light from failing to reach the patient's blood vessels due to obesity, thereby improving the detection depth of the vascular imaging device.

[0004] However, the aforementioned disclosed patents and existing infrared vascular image enhancement devices in the market still have some shortcomings: When these devices clamp a patient's limb, the clamping arms come into direct contact with the patient's skin, making them highly susceptible to bacterial and viral residues. This poses a risk of cross-infection for subsequent patients, making them unsafe and inefficient to use. Therefore, those skilled in the art have provided an infrared vascular image enhancement device to address the problems mentioned in the background section. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an infrared vascular image enhancement device, which solves the problem of insufficient safety and efficiency in existing infrared vascular image enhancement devices mentioned in the background art.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an infrared vascular image enhancement device, including a support platform;

[0007] The support platform is equipped with a clamping braking mechanism inside its frame.

[0008] The clamping braking mechanism includes a brake screw installed in the middle of the support platform and guide rails arranged symmetrically in pairs inside the support platform along the direction of the brake screw shaft. Each set of guide rails is slidably connected to a support slide. The outer side of the brake screw shaft is symmetrically fitted with brake sleeves, and both sides of each set of brake sleeves are symmetrically connected with arm force connecting rods connected to the support slide.

[0009] Image enhancement mechanisms are symmetrically arranged above the frames of the two sets of supporting slides;

[0010] The image enhancement mechanism includes two opposing sets of unwinding shells, with clamping arms installed between them. Near-infrared lamps are arranged in an array on the clamping surfaces of the clamping arms. An unwinding roller is rotatably connected inside the shell of the bottom unwinding shell, and an unwinding shaft is installed on the outside of the roller shaft of the unwinding roller. A take-up roller is rotatably connected inside the shell of the top unwinding shell, and a take-up shaft is installed on the outside of the shaft of the take-up roller. A sterile cloth that fits the clamping arms and is connected to the take-up shaft is wound around the outside of the shaft of the unwinding shaft.

[0011] As a further technical solution of this utility model: the sterile cloth is a non-woven fabric material, and the surface of the sterile cloth is arranged in an array with through grooves opposite to the near-infrared lamps.

[0012] As a further technical solution of this utility model: the clamping surfaces of the clamping arms are symmetrically provided with traction guide plates for traction of sterile cloth, and the upper and lower ends of the clamping surfaces of the clamping arms are provided with traction grooves adapted to the sterile cloth.

[0013] As a further technical solution of this utility model: both sets of the roll-up shells are provided with an opening and closing flip cover on one side of the shell.

[0014] As a further technical solution of this utility model: a winding handwheel is provided at one end of the winding roller shaft.

[0015] As a further technical solution of this utility model: the brake screw is divided by the center line, and the two sides of the center line are symmetrically provided with positive and negative threads that are adapted to the two sets of brake screw sleeves.

[0016] As a further technical solution of this utility model: a brake handwheel is provided at one end of the shaft of the brake lead screw.

[0017] This invention provides an infrared vascular image enhancement device, which has the following advantages compared with the prior art:

[0018] The infrared vascular image enhancement device designed here uses a counter-drive clamping mechanism to clamp the opposing arms of the image enhancement mechanism onto the patient's limb to accommodate different patients. Then, the near-infrared lamps arranged in an array on the clamping arms increase the near-infrared light projected onto the patient's limb to more clearly visualize the patient's blood vessels. After use, the sterile cloth in the image enhancement mechanism is rolled up to remove the sterile cloth that came into contact with the patient and to roll up a new sterile cloth, providing the patient with a clean and sterile puncture environment, avoiding cross-infection due to contact, and improving the safety of the patient's vascular puncture.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5This utility model provides a technical solution for an infrared vascular image enhancement device: an infrared vascular image enhancement device includes a support platform 1, and a clamping braking mechanism is provided inside the frame of the support platform 1. The clamping braking mechanism includes a brake screw 7 installed in the middle of the frame of the support platform 1 and guide rails 12 arranged symmetrically in pairs inside the support platform 1 along the axis of the brake screw 7. Each set of guide rails 12 is slidably connected to a support slide 11. Brake screw sleeves 9 are symmetrically sleeved on the outer side of the shaft of the brake screw 7, and arms connected to the support slide 11 are symmetrically connected to both sides of the shaft sleeve of each set of brake screw sleeves 9. The force linkage 10 and the brake screw 7 are symmetrically arranged on both sides of the center line, with positive and negative threads that are compatible with two sets of brake sleeves 9. A brake handwheel 8 is provided at one end of the shaft of the brake screw 7. By controlling the rotation of the brake handwheel 8, the brake screw 7 is driven to rotate. By utilizing the compatibility between the positive and negative threads on the brake screw 7 and the brake sleeves 9, the opposing brake sleeves 9 are pushed to slide symmetrically in opposite directions. Then, by using the arm force linkage 10, the opposing thrust is converted into a horizontal thrust, which pushes the opposing support slide 11 to slide symmetrically horizontally along the guide slide rail 12, clamping the opposing clamping arms 4 to hold and fix the patient's limb.

[0027] Image enhancement mechanisms are symmetrically arranged above the two sets of supporting slides 11. The image enhancement mechanisms include two sets of opposite roll-up shells 3, and clamping arms 4 are installed between the two sets of roll-up shells 3. Near-infrared lamps 6 are arranged in an array on the clamping surfaces of the clamping arms 4. The sterile cloth 15 is made of non-woven fabric, and the surface of the sterile cloth 15 has through slots 151 arranged in an array opposite to the near-infrared lamps 6. When clamping and fixing the patient's limb, the sterile cloth 15 is used to isolate the patient's limb from the device to avoid direct contact between the two. Then, by using the projection of the near-infrared lamps 6, the patient's blood vessels are enhanced more clearly. Furthermore, by opening through slots 151 on the sterile cloth 15 opposite to the near-infrared lamps 6, the situation of blocking the infrared light can be avoided.

[0028] A winding shaft 14 is installed on the outer side of the winding roller 17, and a winding shaft 16 is installed on the outer side of the shaft of the winding roller 18. A sterile cloth 15 that fits against the clamping arm 4 and is connected to the winding shaft 16 is wound around the outer side of the winding shaft 14. The clamping surfaces of the clamping arm 4 are symmetrically provided with traction guide plates 5 for traction of the sterile cloth 15. The upper and lower ends of the clamping surfaces of the clamping arm 4 are provided with traction slots 20 that are adapted to the sterile cloth 15. A winding handwheel 19 is provided at one end of the roller shaft of the winding roller 18. After the patient is punctured, the winding handwheel 19 can be rotated to drive the winding roller 18 to rotate, which in turn drives the winding shaft 16 to rotate, thereby winding up the sterile cloth 15 that has been in contact with the patient. At the same time, the sterile cloth 15 that has not been in contact with the winding shaft 14 is rolled out and pulled out, and then attached to the clamping surface of the clamping arm 4 again, serving as a sterile control platform for the next group of patients.

[0029] The bottom roll-up shell 3 is rotatably connected to the inside of the shell, and the top roll-up shell 3 is rotatably connected to the inside of the shell, and the shell of both sets of roll-up shells 3 is provided with an opening and closing flap 13 on one side. After the sterile cloth 15 is used up, the roll-up shaft 14 on the roll-up roller 17 and the winding shaft 16 on the winding shaft 18 can be simultaneously disassembled and replaced with a new sterile cloth 15 roll structure by opening the opening and closing flap 13.

[0030] The working principle of this utility model is as follows: When using the image enhancement device to provide infrared images for vascular puncture of patients, after the patient's limb is placed between the clamping arms 4, the brake handwheel 8 is rotated to drive the brake screw 7 to rotate. By using the matching of the positive and negative threads on the brake screw 7 with the brake sleeve 9, the corresponding brake sleeve 9 is pushed to slide symmetrically in opposite directions. Then, by using the arm force of the arm force linkage 10, the opposing thrust is converted into a horizontal thrust, which pushes the corresponding support slide 11 to slide symmetrically horizontally along the guide slide rail 12, clamping the corresponding clamping arms 4 together, and stably clamping and fixing the limbs of patients of different body types.

[0031] Then, when clamping and fixing the patient's limb, the sterile cloth 15 is used to isolate the patient's limb from the device to avoid direct contact between the two and the possibility of bacterial and viral residue. Then, the near-infrared lamp 6 is used to project and enhance the imaging of the patient's blood vessels more clearly.

[0032] Furthermore, after the patient's blood vessel puncture is completed, the winding handwheel 19 is rotated, which drives the winding roller 18 to rotate, and then drives the winding shaft 16 to rotate, winding up the sterile cloth 15 that has been in contact with the patient. At the same time, the sterile cloth 15 that has not been in contact with the unwinding shaft 14 is rolled out and pulled out, and then attached to the clamping surface of the clamping arm 4 again, serving as a sterile operation platform for the next group of patients. This provides patients with a clean and sterile puncture environment, avoids cross-infection due to mutual contact, and improves the safety of operation.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
