Description

Technical Field

[0001] This invention relates to the field of medical auxiliary device technology, and more specifically, to a structure for outpatient puncture and pulse pressure using the back of the hand. Background Technology

[0002] Vein pressure devices are typically used to help doctors or nurses better locate veins during venipuncture, especially on the back of the hand. Venipuncture is an important medical procedure for drawing blood or injecting medication, and accurate vein location is crucial to ensuring the procedure is performed successfully.

[0003] Because the hand pillow and the pressing component are fixedly connected and difficult to separate, after the operation, the patient still needs to use the hand pillow in conjunction with the pressing component to continue pressing the puncture site for a certain period of time. If there are many patients waiting in line for coronary intervention on the same day, this situation makes it difficult to improve the efficiency of coronary intervention surgery. In response to the above problems, the existing technology has also provided some solutions. For example, Chinese patent with authorization announcement number CN221013366U discloses a radial artery puncture fixation structure with a detachable pressing component. This device can avoid the impact on subsequent waiting interventional surgeries by setting the pressing component and the puncture fixation structure to be used separately.

[0004] However, in actual production operations, the above-mentioned device cannot determine whether the blood vessels on the back of the patient's hand have expanded to the appropriate degree. When the blood vessels have not expanded to the optimal filling state, the needle may deviate from the blood vessel, resulting in puncture failure. It is difficult to help staff accurately determine the best time for needle insertion. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide an outpatient puncture and pressure pulse structure using the back of the hand.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A surgical hand dorsum puncture and pulse pressure structure includes a tightening band, an installation block fixedly installed at the upper middle part of the tightening band, a rotating seat rotatably connected to the upper end of the installation block, a movable bracket rotatably installed on the rotating seat, and a fixed rod rotatably connected to the side of the movable bracket away from the installation block. The movable bracket is used to adjust the position of the fixed rod.

[0008] A vascular imaging device is fixedly installed on one side of the lower end of the fixing rod. The vascular imaging device is used to irradiate the blood vessels on the back of the patient's hand.

[0009] A pressure detection component is also installed at the lower end of the fixed rod. A sleeve is fixedly installed at the lower end of the fixed rod. The pressure detection component includes a movable rod that is slidably installed inside the sleeve. The pressure detection component also includes a first pressure sensor that is fixedly installed at the lower end of the movable rod. The first pressure sensor is in pressure contact with the tendons on the back of the patient's hand. A pressure spring is connected between the upper end of the movable rod and the top wall of the sleeve. The pressure spring is used to compress the movable rod.

[0010] Optionally: A first electronic rotating shaft is fixedly installed at the lower middle part of the rotating seat. The first electronic rotating shaft is rotatably installed in the mounting block, and the rotating seat and the movable bracket are rotatably connected through a second electronic rotating shaft.

[0011] Optionally: The inner wall of the tightening belt is embedded with multiple magnets, and the inner wall of the tightening belt is fitted with a pressure pad. Multiple metal pieces are fixedly installed on the side of the pressure pad near the tightening belt. The magnets and the metal pieces are magnetically connected respectively. Multiple heating wires are embedded inside the tightening belt.

[0012] Optionally: One end of the tightening belt is fixedly installed with a fixing ring, and the other end of the tightening belt passes through the fixing ring.

[0013] Optionally: Multiple limiting blocks are fixedly installed on the outer wall of the side of the tightening belt where the fixing ring is provided, and a hanging ring is fixedly installed on the end of the tightening belt where the fixing ring is not provided. The hanging ring is connected to a pull rope by a hook, and the pull rope passes through multiple limiting blocks in sequence and extends to one side of the mounting block.

[0014] Optionally: A drive motor is fixedly installed on the outer wall of the mounting block near the end of the pull rope, and a winding wheel is fixedly installed at the output end of the drive motor, with the end of the pull rope near the winding wheel wound on the winding wheel.

[0015] Optionally: A data processing module is fixedly installed on the upper end of the fixed rod, and a first pressure sensor is electrically connected to the data processing module. The first pressure sensor is used to transmit pressure data to the data processing module. The data processing module analyzes the change values ​​of the data transmitted by the first pressure sensor. A display screen is also fixedly installed on the upper end of the fixed rod, and the data processing module transmits the detected pressure data to the display screen.

[0016] Optionally, a control module is also fixedly installed on the upper end of the fixed rod. The data processing module is electrically connected to the control module, and the control module is electrically connected to the drive motor, the first electronic rotating shaft, and the second electronic rotating shaft. The control module is used to receive data transmitted by the data processing module and control the drive motor to rotate forward or in reverse. The control module is also used to control the rotation of the first electronic rotating shaft and the second electronic rotating shaft.

[0017] Optionally: A second pressure sensor is embedded in the bottom surface of the tightening band located at the bottom of the mounting block. The second pressure sensor is electrically connected to the data processing module. The second pressure sensor transmits data to the data processing module. When the data processing module receives the data signal from the second pressure sensor, it sends a signal to the control module.

[0018] Optionally, the control module is electrically connected to the vascular imaging instrument, and the control module is also used to control the opening and closing of the vascular imaging instrument.

[0019] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0020] In the above scheme, the vascular imaging device can help staff determine the location of blood vessels, and the first pressure sensor can effectively detect the condition of blood vessels, helping staff determine whether the blood vessels are in the optimal filling state, which can improve the success rate of puncture.

[0021] The drive motor, in conjunction with the pull rope, controls the pressure of the tightening band on the blood vessels under the action of the data processing module and the control module. This keeps the blood vessel pressure stable, avoids excessive pressure that could cause discomfort to the patient, and ensures that the blood vessels remain full.

[0022] By setting up a first electronic rotating shaft in conjunction with a second electronic rotating shaft, the movable support and fixing rod can be automatically removed from the back of the patient's hand after the puncture is completed under the control of the control module, making it convenient for staff to apply tape to the back of the patient's hand to fix the needle and syringe.

[0043] like Figures 1 to 9As shown, this embodiment of the invention provides an outpatient hand dorsum puncture and pulse pressure structure, including: a tightening band 1, an installation block 101 fixedly installed at the middle of the upper end of the tightening band 1, a rotating seat 102 rotatably connected to the upper end of the installation block 101, and a movable bracket 103 rotatably installed on the rotating seat 102. The movable bracket 103 can be a self-locking bracket, that is, the multiple arms of the movable bracket 103 can be locked at any position by friction, or the multiple arms of the movable bracket 103 can be fixed by installing bolts between the multiple arms of the movable bracket 103 and using the self-locking nature of the bolts. A fixing rod 2 is rotatably connected to the side of the movable bracket 103 away from the installation block 101. The movable bracket 103 and the fixing rod 2 can also be fixed at any position by friction. At the same time, the movable bracket 103 and the fixing rod 2 can also be fixed by installing bolts at the connection between the movable bracket 103 and the fixing rod 2. The movable bracket 103 is used to adjust the position of the fixing rod 2.

[0044] A vascular imaging device 201 is fixedly installed on one side of the lower end of the fixing rod 2. The vascular imaging device 201 is used to irradiate the blood vessels on the back of the patient's hand. The vascular imaging device 201 can be an infrared vascular imaging device 201. By irradiating the back of the patient's hand, the blood vessels on the back of the patient's hand can be made visible, which makes it easier for staff to locate the blood vessel position and increases the accuracy and safety of puncture.

[0045] A pressure detection component 3 is also installed at the lower end of the fixed rod 2. A sleeve 301 is fixedly installed at the lower end of the fixed rod 2. The pressure detection component 3 includes a movable rod 302 that is slidably installed inside the sleeve 301. The pressure detection component 3 also includes a first pressure sensor 303 that is fixedly installed at the lower end of the movable rod 302. The first pressure sensor 303 is in pressure contact with the tendons on the back of the patient's hand. A pressure spring 304 is installed at the upper end of the movable rod 302. The lower end of the pressure spring 304 is fixedly connected to the upper end of the movable rod 302. The end of the pressure spring 304 away from the movable rod 302 is fixedly connected to the top inner wall of the sleeve 301. The pressure spring 304 is used to compress the movable rod 302.

[0046] By adopting the above technical solution, when using the device, the tightening strap 1 is placed on the patient's wrist. Then, the movable support 103 is adjusted to change its direction. The vascular imaging device 201 is then turned on to irradiate the back of the patient's hand, making the blood vessels visible. The position of the movable support 103 is then adjusted again so that the lower end of the first pressure sensor 303 corresponds to the position of the blood vessel on the back of the patient's hand, and the first pressure sensor 303 is in contact with the back of the patient's hand. The pressure spring 304 can apply pressure to the moving rod 302 when the blood vessel expands, thereby applying pressure to the first pressure sensor 303. During the expansion of the blood vessel, the first pressure sensor 303 detects a change in the pressure value.

[0047] like Figure 1 and Figure 3 As shown, a first electronic rotating shaft 104 is fixedly installed at the lower middle part of the rotating seat 102. The first electronic rotating shaft 104 is rotatably installed in the mounting block 101. The rotating seat 102 is rotatably connected to the mounting block 101 through the first electronic rotating shaft 104. The rotating seat 102 is rotatably connected to the movable bracket 103 through a second electronic rotating shaft 105. The first electronic rotating shaft 104 is used to control the rotation of the rotating seat 102 relative to the mounting block 101, and the second electronic rotating shaft 105 is used to control the rotation of the movable bracket 103 relative to the rotating seat 102.

[0048] By adopting the above technical solution, when the first electronic rotating shaft 104 is working, it can drive the rotating seat 102 to rotate, thereby causing the movable support 103 on the rotating seat 102 to rotate. At this time, the movable support 103 can drive the fixing rod 2 to move away from the back of the patient's hand, so that the first pressure sensor 303 no longer corresponds to the patient's blood vessel position. When the second electronic rotating shaft 105 is working, it can drive the movable support 103 to rotate relative to the rotating seat 102, thereby causing the side of the movable support 103 close to the fixing rod 2 to tilt up. This can cooperate with the first electronic rotating shaft 104 to move the fixing rod 2 and the first pressure sensor 303 away from the back of the patient's hand, making it easier for staff to apply sterile tape to the injection site and fix the needle and syringe.

[0049] like Figures 3 to 6 As shown, the inner wall of the tightening band 1 is embedded with multiple magnets 106, and a pressure pad 107 is attached to the inner wall of the tightening band 1. The pressure pad 107 is a sterile pressure pad 107, which is used to separate the tightening band 1 from the patient's skin, thereby reducing the risk of cross-infection. Multiple metal pieces 108 are fixedly installed on the side of the pressure pad 107 near the tightening band 1. The number of metal pieces 108 is the same as that of the magnets 106 and their positions correspond. The magnets 106 and the metal pieces 108 are magnetically connected respectively. Multiple heating wires 109 are embedded inside the tightening band 1.

[0050] By adopting the above technical solution, the metal sheet 108 and the magnet 106 work together to facilitate the removal and replacement of the pressure pad 107 by the staff, thereby improving work efficiency. The heating wire 109 can provide temperature to the blood vessels in the patient's hand, improving the patient's treatment experience and promoting blood vessel dilation, which facilitates needle administration.

[0051] like Figures 1 to 4As shown, a retaining ring 110 is fixedly installed at one end of the tightening belt 1, and the other end of the tightening belt 1 passes through the retaining ring 110 to the other side. Multiple limiting blocks 112 are evenly fixedly installed on the outer wall of the side of the tightening belt 1 with the retaining ring 110. The limiting blocks 112 are arranged along the arc length direction of the tightening belt 1. A hanging ring 113 is fixedly installed at the end of the tightening belt 1 without the retaining ring 110, and a pull rope 115 is hooked on the hanging ring 113 through a hook 114. The pull rope 115 passes through multiple limiting blocks 112 in sequence and extends to one side of the mounting block 101. A drive motor 116 is installed on the outer wall of the mounting block 101 near the end of the pull rope 115. A winding wheel 117 is fixedly installed at the output end of the drive motor 116. The end of the pull rope 115 near the winding wheel 117 is wound on the winding wheel 117.

[0052] By adopting the above technical solution, when the tightening band 1 is tied to the patient's wrist, one end of the tightening band 1 is passed through the fixing ring 110, and the hook 114 is hung on the hanging ring 113. Then, the drive motor 116 drives the take-up wheel 117 to rotate. After the take-up wheel 117 rotates, it can wind the pull rope 115. At this time, the take-up wheel 117 can pull the pull rope 115. The pull rope 115 pulls the hook 114, and the hook 114 pulls the hanging ring 113, thereby tightening the tightening band 1. At this time, the pulse pressure pad 107 can squeeze the blood vessels in the patient's wrist as the tightening band 1 tightens, thereby achieving the effect of dilating the blood vessels on the back of the hand.

[0053] like Figures 1 to 8 As shown, a data processing module 202 is fixedly installed on the upper end of the fixed rod 2. The first pressure sensor 303 is used to transmit pressure data to the data processing module 202. The data processing module 202 analyzes the change value of the data transmitted by the first pressure sensor 303. A display screen 205 is also fixedly installed on the upper end of the fixed rod 2. The data processing module 202 transmits the detected pressure data to the display screen 205.

[0054] A control module 203 is also fixedly installed on the upper end of the fixed rod 2. The control module 203 is used to control the forward and reverse rotation of the drive motor 116, and the control module 203 is also used to control the rotation of the first electronic shaft 104 and the second electronic shaft 105.

[0055] A second pressure sensor 204 is embedded on the bottom surface of the tightening band 1 at the bottom end of the mounting block 101. The second pressure sensor 204 transmits data to the data processing module 202. When the data processing module 202 receives the data signal from the second pressure sensor 204, it sends a signal to the control module 203. The control module 203 is also used to control the opening and closing of the vascular imaging device 201.

[0056] By adopting the above technical solution, when the pressure value detected by the first pressure sensor 303 is too high, the data processing module 202 sends a signal to the control module 203. The control module 203 then controls the drive motor 116 to rotate in the reverse direction, causing the winding wheel 117 to rotate, thereby loosening the pull rope 115 and reducing the pressure on the blood vessel. When the pressure value is insufficient, the control module 203 controls the drive motor 116 to rotate in the forward direction, causing the winding wheel 117 to rotate, thus tightening the pull rope 115 and increasing the pressure on the blood vessel. When the tightening band 1 is placed on the patient's wrist, the second pressure sensor 204 receives the pressure signal and transmits the pressure value to the data processing module 202. At this time, the data processing module 202 sends a signal to the control module 203, which then controls the drive motor 116 to rotate in the reverse direction, causing the winding wheel 117 to rotate, thereby loosening the pull rope 115 and increasing the pressure on the blood vessel. 16 drives the winding wheel 117 to rotate, tightening the pull rope 115. During the acupuncture process, when the needle is inserted into the blood vessel, the pressure in the blood vessel will rise again. At this time, the value of the first pressure sensor 303 will increase rapidly. At this time, the data processing module 202 can identify whether the pressure increase in the blood vessel is caused by the acupuncture based on the speed of the pressure change. When the needle stabilizes inside the blood vessel, the pressure inside the blood vessel no longer rises, which means the acupuncture is over. The data processing module 202 can send a signal to the control module 203. The control module 203 first controls the second electronic shaft 105 to rotate, and then controls the first electronic shaft 104 to rotate, so that the fixing rod 2 is disengaged from the initial position. Then, the drive motor 116 drives the winding wheel 117 to rotate, so that the pull rope 115 gradually loosens until it no longer compresses the blood vessel.

[0057] The working process provided by this invention is as follows:

[0058] In use, the present invention first sets the optimal needle pressure value in the data processing module 202. Then, after the tightening band 1 is put on the patient's arm, the hook 114 is connected to the hanging ring 113. At this time, after pulling the tightening band 1, the second pressure sensor 204 can detect the data change and transmit the data to the data processing module 202. The data processing module 202 can then control the drive motor 116 to work through the control module 203 to tighten the tightening band 1 and compress the blood vessels in the patient's hand, causing the blood vessels to expand. Since the data processing module 202 receives the signal from the second pressure sensor 204, the data processing module 202 turns on the vascular imaging device 201 through the control module 203 and uses the vascular imaging device 201 to irradiate the back of the patient's hand to help the staff determine the location of the blood vessels.

[0059] Meanwhile, after the blood vessel expands, the first pressure sensor 303 can detect the pressure signal and transmit it to the data processing module 202. The data processing module 202 determines whether the blood vessel pressure has reached the specified pressure based on the preset pressure value. When the blood vessel pressure reaches the specified pressure value, the data processing module 202 transmits the data to the display screen 205, which displays the value. At this time, the staff can know whether the blood vessel pressure has reached the optimal acupuncture requirement. After the acupuncture is completed, the tightening band 1 is loosened and removed. In cases where the blood vessel pressure is too high, the data processing module 202 controls the control module 203 to reverse the drive motor 116 to control the winding wheel 117 to rotate in the opposite direction to loosen the pull rope 115, thereby reducing the pressure of the tightening band 1 on the wrist. The reduced pressure keeps the blood vessel pressure stable and safe, facilitating acupuncture. After acupuncture, the data processing module 202 and control module 203 control the first electronic rotating shaft 104 and the second electronic rotating shaft 105 to move the movable support 103 and the fixing rod 2 away from the upper side of the patient's hand, making it easier for staff to apply tape to fix the needle and syringe. Then, the control module 203 controls the drive motor 116 to drive the winding wheel 117 to rotate, gradually loosening the pull rope 115 until it no longer compresses the blood vessel. After the tightening band 1 is loosened, the second pressure sensor 204 can detect the data change and transmit the data to the data processing module 202. The data processing module 202 can then control the vascular imaging device 201 to be shut down through the control module 203.
