Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an ultrasound probe positioning bracket for peripheral vein blood collection. Background Technology

[0002] With the development of medical imaging technology, ultrasound probes play a crucial role in many medical procedures, especially in techniques such as vascular localization and venous puncture. Precise ultrasound-guided procedures have become an effective means of improving success rates and reducing complications. During peripheral venous blood collection, particularly when operating on veins that are difficult to locate, the precise positioning and stability of the ultrasound probe directly affect the blood collection effect and patient comfort. However, most existing ultrasound probe positioning devices have the following shortcomings:

[0003] Inaccurate positioning: Existing ultrasound probe holders often cannot provide precise height and angle adjustments, resulting in suboptimal contact between the ultrasound probe and the skin, thus affecting the clarity of ultrasound images and the accuracy of vein localization. This is especially critical when adjusting the ultrasound probe position on different patients' arms, but existing holders typically lack flexible adjustment mechanisms.

[0004] Poor stability: Due to the relatively simple design of existing stents, many positioning devices have failed to effectively address stability issues. During the procedure, especially when the patient moves, the stent may shift position, leading to reduced stability of the ultrasound probe and affecting the accuracy of vein positioning and the smooth progress of blood collection.

[0005] Inconvenient to operate: Existing support systems are often complex in structure and lack adjustability and disassembly capabilities, making the storage, handling, and adjustment of the equipment very inconvenient. Moreover, noise and slippage issues may arise during prolonged use, affecting the operator's experience.

[0006] Susceptible to external interference: Existing stent designs often lack effective anti-slip design and stable support. Especially when used on desktops or other flat surfaces, the stent may slip or become unstable, affecting the accuracy of medical procedures and patient safety. Utility Model Content

[0007] To address the aforementioned technical shortcomings, the purpose of this invention is to provide an ultrasonic probe positioning bracket for peripheral venous blood collection, solving the problems of positioning accuracy, bracket stability, and ease of operation.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An ultrasound probe positioning bracket for peripheral venous blood collection includes:

[0010] The bracket is configured with two brackets, which are symmetrically spaced apart; the bracket includes a base rod and a vertical rod; the vertical rod is vertically installed on the base rod; the vertical rod is provided with an adjustment groove.

[0011] The crossbeam has a slot in the middle for mounting an ultrasonic probe; a positioning tube is fixedly installed at the end of the crossbeam; the crossbeam is placed between two uprights, and the positioning tube is movably inserted into the adjusting vertical groove.

[0012] The adjuster has two components, symmetrically arranged at both ends of the crossbeam. Each adjuster includes a pressure rod, a first spring, and multiple telescopic units. One end of the pressure rod is inserted into the positioning tube, and the other end extends to the outside of the positioning tube. The first spring is placed inside the positioning tube and sleeved on the pressure rod. One end of the first spring is fixedly connected to the positioning tube, and the other end is fixedly connected to the pressure rod. The multiple telescopic units are arranged in a circular array around the axis of the pressure rod. Each telescopic unit includes a telescopic rod, a slider, and a second spring. The positioning tube has a telescopic hole for accommodating the telescopic rod, and the extension line of the telescopic hole's axis passes perpendicularly through the axis of the positioning tube. The telescopic rod is slidably mounted on the extension... In the shrinkage hole, one end extends into the interior of the positioning tube, and the other end extends into the exterior of the positioning tube and abuts against the upright rod; the slider is placed inside the positioning tube and fixedly connected to the telescopic rod; the second spring is placed inside the positioning tube and sleeved on the telescopic rod, with one end fixedly connected to the positioning tube and the other end fixedly connected to the slider; a first inclined surface is provided on the pressure rod; a second inclined surface is provided on the slider that matches the first inclined surface, and the first inclined surface is fitted to the second inclined surface; when the pressure rod is pushed into the interior of the positioning tube, and the pressure rod moves towards the interior of the positioning tube along the axial direction of the positioning tube, the telescopic rod moves towards the axial direction of the positioning tube along the axial direction of the telescopic hole.

[0013] Preferably, an anti-slip pad is provided in the adjusting vertical groove; the anti-slip pad is fixed on the upright.

[0014] Preferably, a silicone pad is fixedly provided on the lower end surface of the base rod.

[0015] Preferably, a cross-shaped insert is fixedly provided at the bottom of the upright; a cross-shaped slot adapted to the cross-shaped insert is provided on the bottom rod; the cross-shaped insert is inserted into the cross-shaped slot.

[0016] Preferably, a plurality of cross slots are provided; the plurality of cross slots are arranged in an array at equal intervals along the length of the base rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This support system allows for precise adjustment of the crossbeam and ultrasound probe. The adjuster, through a combination of levers, springs, and telescopic units, effectively adjusts the height and angle of the crossbeam, enabling fine-tuning of the ultrasound probe according to the patient's specific needs and ensuring good contact between the probe tip and the skin surface. Especially beneficial for patients of different body types, users can easily adjust the angle of the support to ensure the ultrasound probe maintains the correct scanning position, thereby improving the accuracy of vein localization.

[0019] By installing anti-slip pads within the adjusting vertical groove, the friction between the telescopic rod and the upright is enhanced, ensuring the crossbeam is firmly fixed to the upright and preventing loosening or displacement of the support during operation. This design effectively improves the overall stability of the support, reduces operational errors caused by support instability, and increases the success rate of blood collection.

[0020] The connection between the base and the upright uses a cross-shaped insert and slot structure, allowing users to easily detach the upright from the base as needed. This design not only saves storage space but also makes the bracket easier to carry and assemble. Whether for routine use by doctors in the hospital or for temporary operations during surgery, this structure greatly facilitates the storage and transportation of the equipment.

[0021] This invention incorporates a silicone pad on the lower end of the base rod, effectively preventing the support from sliding on the desktop and eliminating noise generated when the base rod moves across the surface. This design enhances the stability of the support, avoids external interference during operation, and thus ensures the precision of the doctor's operation and the comfort of the patient.

[0022] Because the regulator uses multiple telescopic units, it can provide finer adjustments as needed, resulting in more stable contact between the ultrasound probe and the skin, while significantly reducing patient discomfort caused by unstable support. Furthermore, the device's noiseless design and robust support greatly enhance comfort and safety during medical procedures. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings.

[0034] like Figures 1 to 8 As shown, an ultrasound probe positioning bracket for peripheral venous blood collection includes:

[0035] The bracket is configured with two brackets, which are symmetrically spaced apart; the bracket includes a base rod 7 and a vertical rod 5; the vertical rod 5 is vertically installed on the base rod 7; the vertical rod 5 is provided with an adjustment groove 4.

[0036] A crossbeam 1 has a slot 2 for installing an ultrasound probe in the middle; a positioning tube 9 is fixedly installed at the end of the crossbeam 1; the crossbeam 1 is placed between two uprights 5, and the positioning tube 9 is movably inserted into the adjusting vertical groove 4; when in use, the other arm is placed between the two supports and below the crossbeam 1, and the ultrasound probe is installed in the slot 2, with the front end of the ultrasound probe attached to the patient's skin.

[0037] Two adjusters are configured, symmetrically arranged at both ends of the crossbeam 1. Each adjuster includes a pressure rod 3, a first spring 11, and multiple telescopic units. One end of the pressure rod 3 is inserted into the positioning tube 9, and the other end extends to the outside of the positioning tube 9. The first spring 11 is placed inside the positioning tube 9 and sleeved on the pressure rod 3. One end of the first spring 11 is fixedly connected to the positioning tube 9, and the other end is fixedly connected to the pressure rod 3. Multiple telescopic units are arranged in a circular array around the axis of the pressure rod 3. Each telescopic unit includes a telescopic rod 10, a slider 13, and a second spring. The positioning tube 9 has a telescopic hole 16 for accommodating the telescopic rod 10, and the extended axis of the telescopic hole 16 passes perpendicularly through the axis of the positioning tube 9. The telescopic rod 10 is slidably installed in the telescopic hole 16, with one end extending into the interior of the positioning tube 9 and the other end extending to the outside of the positioning tube 9 and abutting against the upright rod 5. The slider 13 is placed inside the positioning tube 9 and fixedly connected to the telescopic rod 10. The second spring... The pressure rod 3 is placed inside the positioning tube 9 and sleeved on the telescopic rod 10. One end is fixedly connected to the positioning tube 9, and the other end is fixedly connected to the slider 13. The pressure rod 3 is provided with a first inclined surface 14. The slider 13 is provided with a second inclined surface 15 that matches the first inclined surface 14. The first inclined surface 14 is set to fit against the second inclined surface 15. When the pressure rod 3 is pushed into the positioning tube 9, the telescopic rod 10 moves along the axis of the positioning tube 9 towards the axis of the positioning tube 9. After the pressure rod 3 is released, the first spring 11 pushes the pressure rod 3 outward from the positioning tube 9, so that the pressure rod 3 returns to its initial position. Through the sliding contact between the first inclined surface 14 of the pressure rod 3 and the second inclined surface 15 of the slider 13, the telescopic rod 10 is pushed away from the axis of the positioning tube 9, so that the end of the telescopic rod 10 abuts against the upright 5, fixing the relative position between the crossbeam 1 and the upright 5.

[0038] In this embodiment, an anti-slip pad 6 is provided in the adjusting vertical groove 4; the anti-slip pad 6 is fixed on the upright 5 to increase the friction between the telescopic rod 10 and the upright 5, making the crossbeam 1 more stable on the upright 5.

[0039] In this embodiment, a silicone pad is fixedly provided on the lower end surface of the base rod 7, so that it does not slip when placed on the table and can eliminate the noise when the base rod 7 slides on the table.

[0040] In this embodiment, a cross-shaped insert rod 12 is fixedly provided at the bottom of the upright pole 5; a cross-shaped slot 8 adapted to the cross-shaped insert rod 12 is provided on the bottom pole 7; the cross-shaped insert rod 12 is inserted into the cross-shaped slot 8, so that the upright pole 5 can be removed from the bottom pole 7, reducing the overall space occupation and facilitating storage and retrieval.

[0041] In this embodiment, multiple cross slots 8 are configured; multiple cross slots 8 are arranged in an array at equal intervals along the length of the base rod 7. During use, different cross slots 8 are selected to insert the cross rod 12, adjusting the distance between the crossbeam 1 and the medical staff for easy operation.

[0042] Working principle:

[0043] This invention relates to an ultrasound probe positioning bracket for peripheral vein blood collection. Its working principle mainly involves the cooperation of components such as the bracket, crossbeam 1, and adjuster to achieve precise positioning and stable support of the ultrasound probe, ensuring that the ultrasound probe can accurately contact the patient's skin during blood collection, thereby improving blood collection efficiency and safety.

[0044] Basic structure of support and crossbeam 1

[0045] The support system consists of two symmetrically arranged supports, each including a base rod 7 and a vertical rod 5 mounted on the base rod 7. The two supports are connected by a crossbeam 1, which has a slot 2 for securing the ultrasound probe in the middle. When the device is in use, the patient's arm is placed between the two supports, below the crossbeam 1, with the tip of the ultrasound probe against the patient's skin, ensuring accurate scanning of vein locations.

[0046] The function of the regulator

[0047] The adjuster is located at both ends of the crossbeam 1 and consists of a pressure rod 3, a first spring 11, and multiple telescopic units. One end of the pressure rod 3 is inserted into the positioning tube 9, and the other end extends outward. Through the axial movement of the pressure rod 3, the telescopic units move along the axis of the telescopic rod 10, thereby adjusting the position of the crossbeam 1 so that its height and angle can be adjusted according to different patients' arms and operational needs, ensuring that the ultrasound probe is always stably fixed in the appropriate position during blood collection.

[0048] Working principle of telescopic unit

[0049] Under the push of the pressure rod 3, the telescopic rod 10 slides within the telescopic hole 16. The movement of the telescopic rod 10 is limited by the cooperation of the second spring and the slider 13. The elastic force of the second spring can return the telescopic rod 10 to its initial position. When the pressure rod 3 is pushed into the positioning tube 9, the telescopic rod 10 moves in the direction of the axis of the positioning tube 9, thereby realizing the fine adjustment of the position of the crossbeam 1. After the pressure rod 3 is released, the first spring 11 pushes the pressure rod 3 back to its initial position. Through the sliding contact between the pressure rod 3 and the slider 13, the end of the telescopic rod 10 pushes the relative position of the crossbeam 1, fixing it on the upright 5 and ensuring the stability of the entire support system.

[0050] Anti-slip design and disassembly function

[0051] To enhance stability, anti-slip pads 6 are installed inside the adjusting groove 4 to increase the friction between the telescopic rod 10 and the upright rod 5, ensuring that the crossbeam 1 is securely fixed. The connection between the upright rod 5 and the base rod 7 employs a cross-shaped insert 12 and a cross-shaped slot 8, allowing users to disassemble the upright rod 5 and the base rod 7 as needed, thus facilitating storage and reducing space occupation.

[0052] Anti-slip design of base bar 7

[0053] The bottom of the base rod 7 is fixed with a silicone pad, which can effectively prevent slipping when placed on the table and reduce the noise caused by friction between the base rod 7 and the table, further improving the comfort and stability of use.

[0054] In summary, this invention achieves precise adjustment and fixation of the ultrasonic probe position through the cooperation of the bracket, crossbeam 1, and adjuster. Furthermore, considering ease of use and stability, it incorporates anti-slip pads 6, a disassembly structure, and anti-slip silicone pads, further improving the device's performance and ease of operation.
