Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a painless vascular puncture device with intelligent positioning function. Background Technology

[0002] With the development of modern medical technology, blood tests have become an important means of diagnosing diseases. Blood tests analyze the changes in various blood cells and plasma biomolecules by examining the patient's blood, thereby achieving the purposes of finding the cause of the disease, diagnosing and differentiating diseases, predicting patient outcomes, or evaluating treatment efficacy. After analyzing the patient's disease, treatment needs to be carried out for the diagnosed disease, and intravenous infusion is an effective means of treating the disease. For some patients who have lost a lot of blood, blood transfusion is also a relatively effective treatment method.

[0003] Currently, blood tests, intravenous infusions, and blood transfusions are usually performed by medical staff through vascular puncture at the patient's elbow joint to draw blood, inject medication, and transfer blood. Because each patient's physical characteristics are different, vascular puncture is usually performed manually. However, staff are prone to fatigue when working for long periods, which can lead to errors during the puncture process and cause unnecessary pain to the patient. In addition, less experienced staff are also prone to making mistakes when puncturing patients with thinner blood vessels.

[0004] Therefore, a painless vascular puncture device with intelligent positioning function is needed to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, namely the issue of errors that can easily occur during existing vascular puncture procedures due to various reasons, this invention provides a painless vascular puncture device with intelligent positioning function.

A guide cavity is provided in the top pull rod, and the guide cavity is uniformly connected with multiple spray holes communicating with the outside along the circumferential direction. The output end of the disinfection pump and the output end of the analgesia pump are both connected to the guide cavity.

[0010] Preferably, the output end of the disinfection pump is connected to a first liquid guide tube, the output end of the analgesic pump is connected to a second liquid guide tube, the first liquid guide tube and the second liquid guide tube are connected to a connecting tube, the connecting tube is connected to the guide cavity, and a pressure relief valve is provided in the spray hole.

[0011] Preferably, the extending member further includes a mounting rod fixedly connected to one end of the pull rod near the base, a rod sleeve slidably sleeved on the mounting rod, and a first spring connecting the rod sleeve and the mounting rod.

[0012] Preferably, the auxiliary mechanism further includes a blocking component, the blocking component including a blocking ring slidably sleeved on the pull rod, a connecting rod fixedly connected to the blocking ring, a fixed rod slidably sleeved on the connecting rod, a second spring connecting the connecting rod and the fixed rod, and the fixed rod being fixedly connected to the mounting frame.

[0013] Preferably, the mounting frame has six mounting slots evenly distributed along the circumference, and the detachment component includes a first electric actuator fixedly connected to the inner wall of the mounting slot, the output end of the first electric actuator being slidably connected to the sleeve.

[0014] Preferably, the clamping member includes an abutment plate fixedly connected to the end of the sleeve away from the pull rod. The abutment plate extends out of the mounting groove. Three first electromagnetic slide rails are uniformly fixedly connected along the circumferential direction on the outer circumferential surface of the mounting frame. A first electromagnetic slider is slidably connected in each first electromagnetic slide rail. The three first electromagnetic sliders are jointly fixedly connected to an abutment ring. Six protrusions are uniformly fixedly connected along the circumferential direction on the inner circumferential surface of the abutment ring. Each protrusion can abut against the abutment plate in one of the six extending members.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The vascular imaging device can visualize the patient's blood vessels, assisting staff in performing vascular puncture. Simultaneously, the pull rod, release mechanism, clamping mechanism, and spraying mechanism automatically disinfect the patient's elbow joint. By moving the telescopic belt, alcohol is spread on the elbow joint. After disinfection, the clamping mechanism loosens the telescopic belt, tightening it at the patient's upper arm to slow venous blood return, making the blood vessels at the elbow joint more visible and further assisting staff in vascular puncture. After vascular puncture, the analgesic device applies pain relief solution to the elbow joint, spreading it through the telescopic belt. The telescopic belt then tightens at the puncture site to help stop bleeding.

[0020] 2. The spray mechanism helps staff disinfect and relieve pain at the patient's elbow joint, reducing the workload and increasing efficiency of staff.

[0021] 3. The connecting tube and pressure relief valve allow disinfectant and analgesic solutions to be sprayed from the nozzle through the connecting tube. When the analgesic solution is sprayed, any residual disinfectant in the connecting tube and guide cavity is expelled, further disinfecting the patient's elbow joint and the upper inner wall of the elastic band. This prevents contamination of the elastic band after contact with the patient's upper arm and avoids infection at the needle site. Furthermore, the spraying of disinfectant also expels any residual analgesic solution in the connecting tube and guide cavity, providing a degree of anesthesia to the patient's elbow joint and reducing pain during needle insertion into the blood vessel.

[0022] 4. The design of the lever sleeve and the first spring allows the lever to be adjusted to fit the patient's arm, preventing excessive pressure on the patient's upper arm when the elastic band tightens, which could cause discomfort. Attached Figure Description

[0042] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0043] like Figure 1-12 As shown, this embodiment of the invention discloses a painless vascular puncture device with intelligent positioning function, including a base 1, a vascular imaging instrument 2 disposed on the base 1, and an auxiliary mechanism 3 disposed on the base 1;

[0044] The auxiliary mechanism 3 includes an annular mounting frame 31. Six extending members 32 are evenly arranged in the mounting frame 31 along the circumferential direction. Each extending member 32 includes a pull rod 321. A telescopic belt 33 is provided in the mounting frame 31. The telescopic belt 33 is sleeved on the pull rod 321 of the six extending members 32, making the telescopic belt 33 hexagonal. The pull rod 321 is connected to a release member 34. The release member 34 can drive the pull rod 321 to reciprocate along the axial direction of the mounting frame 31. The pull rod 321 is connected to a clamping member 35. The clamping member 35 can drive the pull rod 321 to reciprocate along the radial direction of the mounting frame 31.

[0045] The top-side extending member 32 is connected to a spraying mechanism 4, which includes a disinfection component 41 and a pain-relieving component 42. The disinfection component 41 contains disinfectant alcohol, and the pain-relieving component 42 contains analgesic liquid. The mounting frame 31 is movable along its axial and radial directions.

[0046] Specifically, during use, the pull rod 321 in the six extending members 32 stretches the telescopic belt 33, making it taut. The patient's arm is then placed on the base 1 through the telescopic belt 33. Simultaneously, the vascular imaging device 2 is activated to visualize the blood vessels at the patient's elbow joint. The mounting frame 31 is then moved to position itself at the patient's elbow joint. The disinfection component 41 in the spray mechanism 4 then sprays disinfectant alcohol to disinfect the patient's elbow joint. Finally, the pull rod 321 in the top extending member 32 moves along the axis of the mounting frame 31 under the action of the disengagement component 34, causing... The telescopic strap 33 disengages from the top pull rod 321. The top of the telescopic strap 33, under its own elastic force, contacts the patient's elbow joint, causing the mounting frame 31 to move along its axial and radial directions. This allows the telescopic strap 33 to spread alcohol on the patient's elbow joint. The mounting frame 31 is then moved to the patient's upper arm, and the pull rod 321 is moved closer to the axis of the mounting frame 31. Simultaneously, the telescopic strap 33 contracts under its own elastic force, tightening the patient's upper arm. The top pull rod 321 then moves back to its original position along the axis of the mounting frame 31, and the top pull rod is reinserted into the telescopic strap. In step 33, under the guidance of the vascular imaging device 2, the staff inserts a needle into the blood vessel at the patient's elbow joint for vascular puncture. After the vascular puncture is completed, the pull rod 321 is moved away from the axis of the mounting 31, causing the telescopic band 33 to expand again. Then, the mounting frame 31 is moved so that the telescopic band 33 is on the same plane as the puncture site. Then, the analgesic component 42 squeezes out the analgesic solution, and the top pull rod 321 moves again along the axis of the mounting frame 31, causing the telescopic band 33 to detach from the top pull rod 321. The top of the telescopic band 33, under its own elastic force, is in contact with the patient's... The arm is brought into contact with the elbow joint, and then the mounting frame 31 is moved back and forth along its axial and radial directions, so that the telescopic band 33 spreads the analgesic solution on the patient's elbow joint. Then the pull rod 321 is brought closer to the axis of the mounting frame 31. When the distance between the pull rod 321 and the patient's arm is less than 2cm, the pull rod 321 is stopped from moving closer to the axis of the mounting frame 31. Then the pull rod 321 is moved along the axis of the mounting frame 31, so that the telescopic band 33 is disengaged from the pull rod 321. After disengagement, the telescopic band 33 tightens again at the patient's elbow joint under its own elastic force and presses the needle hole.

[0047] The vascular imaging device 2 can project the patient's blood vessels, assisting staff in performing vascular puncture. Simultaneously, the pull rod 321, release mechanism 34, clamping mechanism 35, and spraying mechanism 4 automatically disinfect the patient's elbow joint. By moving the telescopic belt 33, alcohol is spread on the patient's elbow joint. After disinfection, the clamping mechanism 35 loosens the telescopic belt 33, tightening it at the patient's upper arm to slow venous blood return, making the blood vessels at the elbow joint more visible and further assisting staff in performing vascular puncture. After vascular puncture, the pain relief device 42 squeezes analgesic solution onto the patient's elbow joint, spreading it by moving the telescopic belt 33, and then tightening the belt at the puncture site to help stop bleeding.

[0048] Furthermore, the vascular imaging device 2 is an existing device that utilizes the principle that hemoglobin in the blood absorbs near-infrared light more strongly than other tissues, and can project blood vessels onto the skin surface in real time at a 1:1 scale to display the thickness, direction, distribution and outline of the blood vessels. The specifics will not be elaborated further. The analgesic solution is a solution with analgesic effects such as lidocaine, and the elastic band 33 is made of medical materials.

[0049] like Figure 1 , 6 As shown in Figures 11 and 12, the spraying mechanism 4 includes a liquid storage tank 43 fixedly mounted on the mounting frame 31. An inverted T-shaped partition plate 44 is fixedly connected to the liquid storage tank 43, which divides the liquid storage tank 43 into a disinfection space and an analgesia space. The disinfection space contains disinfectant alcohol, and the analgesia space contains analgesic liquid. The disinfection component 41 includes a disinfection pump 411 communicating with the disinfection space, and the analgesia component 42 includes an analgesia pump 421 communicating with the analgesia space. A guide cavity 46 is provided in the top pull rod 321. The guide cavity 46 is uniformly connected with multiple spray holes 47 communicating with the outside along the circumferential direction. The output ends of the disinfection pump 411 and the analgesia pump 421 are both connected to the guide cavity 46.

[0050] Specifically, when disinfection of the patient's elbow joint is required, the disinfection pump 411 is activated. The disinfection pump 411 extracts the disinfectant alcohol from the disinfection space and sprays it into the guide cavity 46 through the output end of the disinfection pump 411, and then sprays it out through the spray hole 47. When pain relief of the patient's elbow joint is required, the pain relief pump 421 is activated. The pain relief pump 421 delivers the pain relief solution in the pain relief space to the guide cavity 46 through its output end, and sprays it onto the patient's elbow joint through the spray hole 47.

[0051] The spray mechanism 4 helps staff disinfect and relieve pain at the patient's elbow joint, reducing the workload and improving staff efficiency.

[0052] Furthermore, the top of the liquid storage tank 43 has two liquid inlet holes, and the liquid inlet holes are threaded with sealing caps. The two liquid inlet holes are respectively connected to the analgesia space and the disinfection space.

[0053] Specifically, when the disinfectant or analgesic in the storage tank 43 is used up, the sealing cap is opened to replenish the disinfectant or analgesic into the analgesia space or disinfection space, facilitating continuous use of the device.

[0054] like Figure 12 As shown, the output end of the disinfection pump 411 is connected to a first liquid guide tube 412, the output end of the analgesic pump 421 is connected to a second liquid guide tube 422, the first liquid guide tube 412 and the second liquid guide tube 422 are connected to a connecting tube 45, the connecting tube 45 is connected to the guide cavity 46, and a pressure relief valve is provided in the spray hole 47.

[0055] Specifically, during the first use of the device for disinfection, the disinfection pump 411 introduces disinfectant into the first guide tube 412, which then flows into the connecting tube 45 and the guide cavity 46, and is sprayed out through the pressure relief valve and the nozzle 47. For pain relief, the analgesic pump 421 introduces analgesic solution into the second guide tube 422. Simultaneously, the analgesic solution pushes out any residual disinfectant in the connecting tube 45 and the guide cavity 46, and sprays it out through the pressure relief valve and the nozzle 47, so that the disinfectant is sprayed onto the patient's elbow joint and the inner wall of the telescopic band 33 near the upper pull rod 321. During the second use for disinfection, the disinfection pump 411 introduces disinfectant into the first guide tube 412. Simultaneously, the disinfectant pushes out any residual analgesic solution in the connecting tube 45 and the guide cavity 46, and sprays it out through the pressure relief valve and the nozzle 47, so that the analgesic solution is sprayed onto the patient's elbow joint.

[0056] The connection tube 45 and pressure relief valve allow disinfectant and analgesic solutions to be sprayed from the nozzle 47 through the connection tube 45. When the analgesic solution is sprayed, any residual disinfectant in the connection tube 45 and guide cavity 46 is also sprayed out, further disinfecting the patient's elbow joint and the upper inner wall of the elastic band 33. This prevents the elastic band 33 from becoming contaminated after contact with the patient's upper arm and avoids infection at the needle site after contact with the needle. Furthermore, when the disinfectant solution is sprayed, any residual analgesic solution in the connection tube 45 and guide cavity 46 is also sprayed out, providing a certain degree of anesthesia to the patient's elbow joint and reducing pain during needle insertion into the blood vessel.

[0057] It should be noted that the pressure relief valve is existing technology and will not be described in detail here.

[0058] Furthermore, the first liquid guide tube 412, the second liquid guide tube 422, and the connecting tube 45 are made of flexible material.

[0059] like Figure 1-12 As shown, the extending member 32 also includes a mounting rod 322 fixedly connected to one end of the pull rod 321 near the base 1. A rod sleeve 323 is slidably sleeved on the mounting rod 322, and a first spring 324 is connected between the rod sleeve 323 and the mounting rod 322.

[0060] Specifically, when the pull rod 321 moves toward the axis of the mounting frame 31, the six pull rods 321 can adaptively drive the mounting rod 322 into the rod sleeve 323 according to the shape of the patient's arm, and compress the first spring 324.

[0061] By using the sleeve 323 and the first spring 324, the pull rod 321 can be adjusted to fit the patient's arm, preventing excessive pressure on the patient's upper arm when the elastic band 33 tightens, which could cause discomfort.

[0062] like Figure 1-12 As shown, the auxiliary mechanism 3 also includes a blocking member 36, which includes a blocking ring 361 slidably sleeved on the pull rod 321. A connecting rod 362 is fixedly connected to the blocking ring 361. A fixing rod 363 is slidably sleeved on the connecting rod 362. A second spring 364 is connected between the connecting rod 362 and the fixing rod 363. The fixing rod 363 is fixedly connected to the mounting frame 31.

[0063] Specifically, when the six pull rods 321 move toward the base 1, the telescopic belt 33 disengages from the pull rods 321 under the action of the blocking ring 361; when the pull rods 321 move toward the axis of the mounting frame 31, the pull rods 321 drive the blocking ring 361 and the connecting rod 362 to stretch the second spring 364.

[0064] By setting the blocking member 36, when it is necessary to detach the telescopic belt 33 from the pull rod 321, the blocking ring 361 blocks the telescopic belt 33, so that the telescopic belt 33 can detach from the pull rod 321.

[0065] Furthermore, when the lever 321 comes into contact with the patient's upper arm, the elastic force of the first spring 324 and the second spring 364 is insufficient to cause the telescopic belt 33 to undergo significant deformation.

[0066] like Figure 12As shown, the mounting frame 31 has six mounting slots 37 evenly distributed along the circumferential direction. The detachment member 34 includes a first electric push rod 341 fixedly connected to the inner wall of the mounting slot 37. The output end of the first electric push rod 341 is slidably connected to the rod sleeve 323.

[0067] Furthermore, the first electric actuator 341 is existing technology and will not be described in detail further.

[0068] Specifically, when the pull rod 321 needs to disengage the telescopic belt 33, the first electric push rod 341 is activated. The output end of the first electric push rod 341 drives the pull rod 321 to move closer to the base 1, so that the pull rod 321 disengages the telescopic belt 33.

[0069] like Figure 1-12 As shown, the clamping member 35 includes an abutment plate 351 fixedly connected to the end of the sleeve 323 away from the pull rod 321. The abutment plate 351 extends out of the mounting groove 37. Three first electromagnetic slide rails 352 are uniformly fixedly connected along the circumferential direction on the outer circumferential surface of the mounting frame 31. A first electromagnetic slider 353 is slidably connected in each first electromagnetic slide rail 352. The three first electromagnetic sliders 353 are jointly fixedly connected to an abutment ring 354. Six protruding plates 355 are uniformly fixedly connected along the circumferential direction on the inner circumferential surface of the abutment ring 354. Each protruding plate 355 can abut against the abutment plate 351 in the six extending members 32.

[0070] Furthermore, a third spring is connected between the abutment plate 351 and the inner wall of the mounting groove 37, and the elastic force of the third spring can cause the telescopic belt 33 to deform.

[0071] Specifically, when the pull rod 321 needs to move closer to the axis of the mounting frame 31, the first electromagnetic slider 353 is activated, causing it to slide in the first electromagnetic rail 352. This causes the first electromagnetic slider 353 to rotate the abutment ring 354, which in turn causes the abutment ring 354 to move the protruding plate 355. The protruding plate 355 abuts against the abutment plate 351. Because the edge of the protruding plate 355 protrudes, the abutment plate 351 moves closer to the axis of the mounting frame 31, thereby causing the pull rod 321 to move closer to the axis of the mounting frame 31. At the same time, the abutment plate 351 further stretches the third spring. When the pull rod 321 needs to be reset, the first electromagnetic slider 353 is moved in the opposite direction, causing the protruding plate 355 to reset. Simultaneously, the abutment plate 351 resets under the action of the third spring.

[0072] By setting the clamping member 35, the pull rod 321 can be driven to move in the direction of the axis closer to the mounting frame 31.

[0073] like Figure 1-12As shown, the mounting frame 31 is connected to the base 1 via a connecting mechanism 5. The connecting mechanism 5 includes two support rods 51 symmetrically fixedly connected to both sides of the base 1. Each support rod 51 is connected to the mounting frame 31. A second electromagnetic slide rail 52 is fixedly connected to each support rod 51. A second electromagnetic slider 53 is slidably connected in each second electromagnetic slide rail 52. Each second electromagnetic slider 53 is connected to the mounting frame 31.

[0074] Specifically, when the mounting frame 31 needs to move along its axis, the second electromagnetic slider 53 is activated. The second electromagnetic slider 53 slides in the second electromagnetic slide rail 52, thereby driving the mounting frame 31 to move.

[0075] Furthermore, electromagnetic sliders and electromagnetic rails are existing technologies and will not be described in detail here.

[0076] like Figure 1-12 As shown, a second electric push rod 54 is fixedly connected to the second electromagnetic slider 53, and the output end of the second electric push rod 54 is fixedly connected to the mounting frame 31.

[0077] Specifically, when the mounting frame 31 needs to move radially, two second electric actuators 54 are activated, causing the output end of one second electric actuator 54 to extend and the output end of the other second electric actuator 54 to retract, and so on, so that the mounting frame 31 moves back and forth radially.

[0078] like Figure 1-12 As shown, an adaptation mechanism 6 is provided on one end of the base 1 near the auxiliary mechanism 3. The adaptation mechanism 6 includes an installation cavity 61 with an upward opening in the base 1. An airbag 62 is provided in the installation cavity 61. The airbag 62 is connected to the output end of the air pump 63. A support plate 7 is provided on one end of the base 1 away from the auxiliary mechanism 3. The support plate 7 is U-shaped and made of rubber material.

[0079] Specifically, during use, depending on the patient's body type, the air pump 63 is activated, which inflates or deflates the air bag 62, causing the air bag 62 to rise or fall.

[0080] By adapting the settings of mechanism 6, the comfort of using the device for different patients is improved.
