Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a novel device for detecting arterial pulsation and assisting arterial puncture. Background Art

[0002] Arterial puncture is a commonly used nursing operation technique in clinical practice. For patients with severe shock who require emergency treatment and whose condition has not improved after rapid intravenous blood transfusion, arterial puncture is required to increase coronary artery perfusion and effective blood volume. Arterial puncture is also required for continuous monitoring of arterial blood pressure during anesthesia or surgery and for critically ill patients, selective angiography, and interventional treatment.

[0003] The traditional way to find arteries is for medical staff to find them by feeling the pulse based on experience. Since arteries are often accompanied by veins of the same name and are easy to slide, and critically ill patients have slow blood circulation and weak blood vessel pulsation, medical staff often need to perform repeated punctures during the puncture process before they can insert the needle into the patient's artery. The success rate of puncture is low, which brings great pain to patients. Summary of the invention

[0004] The embodiment of the present application provides a novel device for detecting arterial pulsation and assisting arterial puncture, which can solve the problem of inaccurate positioning of the puncture site when manually feeling the pulse and improve the accuracy of arterial puncture.

[0005] The embodiment of the present application provides a novel device for detecting arterial pulsation and assisting arterial puncture. The novel device for detecting arterial pulsation and assisting arterial puncture includes a handle, a detection member and a pulse detection assembly. The detection member is arranged at one end of the handle in the length direction; the pulse detection assembly includes a controller, a vibration sensor and a prompt light. The vibration sensor and the prompt light are both electrically connected to the controller. The prompt light and the controller are both arranged on the handle. The vibration sensor is arranged at the lower end of the detection member for detecting the pulse signal after contacting the patient's skin; after the controller receives the pulse signal from the vibration sensor and the intensity of the pulse signal reaches a preset value, the controller controls the prompt light to send a prompt message.

[0006] In this solution, the handle provides a gripping function, which makes it easy for medical staff to contact the vibration sensor on the detection piece with the patient's skin and move it along the target area of ​​the patient's skin to find the pulse signal of the patient's artery. The setting of the prompt light, when the vibration sensor detects the pulse beating signal, the controller receives the pulse beating signal transmitted by the vibration sensor, and when the vibration sensor monitors that the intensity of the pulse beating signal reaches the preset value, the prompt light will send out a time information to prompt the medical staff that the artery position is successfully located, and the current position contacted by the detection piece is the patient's artery position, and then the detection piece is removed, and the medical staff can puncture the artery at this position.

[0007] In some embodiments, the number of the vibration sensors is set to three, and the three vibration sensors are evenly spaced along the circumference of the detection member at the detection end of the detection member away from the handle.

[0008] In the above technical solution, the number of vibration sensors is set to three, and the patient's artery position can be monitored by the three vibration sensors together, and the position of the artery can be comprehensively analyzed and judged after the pulsation signals of the three vibration sensors are obtained, which has higher accuracy. In addition, the three vibration sensors are evenly spaced along the circumference of the detection member at the detection end of the detection member away from the handle, and the center of the area surrounded by the three vibration sensors on the detection member is the location of the artery, and the position result of the artery detection is more accurate.

[0009] In some embodiments, the number of warning lights is equal to the number of vibration sensors and corresponds one to one.

[0010] In the above technical solution, by making the number of vibration sensors equal and corresponding to the number of indicator lights, when all three indicator lights are lit and in the same state, it means that the position of the artery is successfully located. Compared with one vibration sensor, the three vibration sensors have a wider coverage range and are more efficient in locating the artery. In addition, the three vibration sensors cooperate with each other, and the accuracy of locating the artery is also higher.

[0011] In some embodiments, a novel device for detecting arterial pulsation and assisting arterial puncture further includes a guide column and a contact piece, wherein the guide column is connected to the handle, the detection piece has a guide hole for the guide column to pass through, and the detection piece can be slidably mounted on the guide column; the contact piece is arranged at one end of the plurality of guide columns away from the handle, the contact piece is cylindrical, and the contact piece has a avoidance hole for avoiding the detection piece, and a contact surface for contacting the patient's skin; wherein the detection piece has a detection state and a separation state, wherein when the detection piece is in the detection state, at least a portion of the detection piece is inserted into the contact piece, and the detection end of the detection piece is flush with the contact surface of the contact piece; when the detection piece is in the separation state, the detection piece is separated from the contact piece, and there is a distance between the detection end of the detection piece and the contact piece to form an avoidance area for arterial puncture.

[0012] In the above technical solution, after the probe finds the position of the artery, it is necessary to move the probe away from the skin surface for the medical staff to perform arterial puncture. In fact, when the probe finds the position of the artery, the probe squeezes the skin and may cause the skin to be displaced and deformed to a certain extent. When the position of the artery is successfully located, the probe leaves the skin surface, and the skin resets after losing the squeezing effect of the probe, resulting in a certain deviation when the medical staff reads the arterial position, and there is a problem of inaccurate puncture. Therefore, through the arrangement of the guide column and the contact member, the probe can be slidably arranged on the guide column. When the probe is in the detection state, the contact surface of the contact member contacts the skin, at least part of the probe is inserted in the contact member, and the detection end of the probe also contacts the skin surface, that is, the detection end of the probe and the contact member contact the skin at the same time. When the probe successfully locates the artery, the probe switches from the detection state to the separation state, and the probe slides upward along the guide column away from the contact piece. During the separation of the probe from the skin surface, since the contact piece is always in contact with the skin surface, the contact piece is pressed on the skin area where the artery is successfully located. Therefore, the artery position located during the separation of the probe from the skin will not change. In addition, since there is a gap between the detection end of the probe and the contact piece, a clearance zone for arterial puncture is formed between the probe and the contact piece. Medical staff can directly penetrate the center of the contact piece from the clearance zone to perform arterial puncture. The puncture accuracy is high, and the phenomenon of reduced puncture accuracy of medical staff is avoided after the probe is separated from the skin.

[0013] In some embodiments, the number of guide posts is set to two, and the two guide posts are arranged opposite to each other.

[0014] In the above technical solution, since the medical staff need to insert the probe into the avoidance hole area of ​​the contact piece from the gap of the guide post during arterial puncture, the guide post will have a certain blocking effect on the arterial puncture of the medical staff. Therefore, the more the number of guide posts, the greater the impact on the arterial puncture of the medical staff. Therefore, by setting the number of guide posts to two, the two guide posts can ensure the stability of the probe during the up and down movement, and will not cause interference with the arterial puncture, so that the medical staff can perform arterial puncture more conveniently.

[0015] In some embodiments, the novel arterial pulsation detection and arterial puncture assisting device further includes a driving member, which is disposed on the handle and whose driving end is connected to the detection member. The driving member is used to drive the detection member to slide along the guide column to switch between a detection state and a separation state.

[0016] In the above technical solution, through the setting of the driving member, the driving member can drive the detection member to automatically switch between the detection state and the separation state, without the need for manual operation by medical staff, thereby reducing the workload of medical staff.

[0017] In some embodiments, the novel arterial pulsation detection and arterial puncture assisting device further includes a disinfection component, which is used to spray disinfectant spray in the direction of the avoidance hole of the contact piece; the disinfection component includes a liquid storage box, a power component, a disinfection pipeline and a nozzle, the liquid storage box and the power component are arranged on the handle, the liquid storage box stores disinfectant, the nozzle is arranged on the contact piece, and the power component is used to provide power to transport the disinfectant in the liquid storage box to the nozzle through the disinfection pipeline and spray it out from the nozzle.

[0018] In the above technical solution, since the patient needs to be disinfected when undergoing arterial puncture, a new arterial puncture-assisted device for detecting arterial pulsation includes a disinfection component. When the detection needle successfully locates the artery and the detection needle is in a separated state, the disinfection component can spray disinfectant spray in the direction of the avoidance hole of the contact piece to cover the patient's skin in the arterial area with a layer of disinfectant. This facilitates the disinfection operation before arterial puncture, and medical staff do not need to perform large-area disinfection operations on the patient's skin in advance. Moreover, after the disinfectant is applied in advance, the disinfectant is liquid, which may have a certain impact on the positioning of the vibration sensor, and the disinfectant can easily damage the vibration sensor, affecting the service life of the vibration sensor.

[0019] In some embodiments, a first cavity is provided in the guide column, and the first cavity constitutes a part of the disinfection pipeline. The liquid outlet end of the power component is connected with the upper end of the first cavity through the pipeline. The contact piece is provided with a mounting groove for installing the nozzle. The nozzle is installed in the mounting groove. The lower end of the first cavity is connected with the liquid inlet of the nozzle, and the surface of the nozzle is flush with the wall surface of the inner wall of the contact piece.

[0020] In the above technical solution, by providing the first cavity in the guide column, the guide column can not only guide the sliding of the detection member, but also the first cavity in the guide column can form a part of the disinfection pipeline, which has the dual functions of guiding and delivering the disinfectant. The first cavity delivers the disinfectant in the liquid storage box to the nozzle of the contact member, the disinfection pipeline will not be exposed to the outside, the integration is high, and the delivery stability of the disinfectant is good.

[0021] In some embodiments, there are multiple nozzles, and the multiple nozzles are distributed at intervals along the circumference of the contact member.

[0022] In the above technical solution, by setting the number of nozzles to multiple, multiple nozzles jointly spray disinfectant spray toward the area within the avoidance hole, so that the disinfectant can evenly cover the patient's skin surface, and the disinfection effect on the patient's artery position is better.

[0023] In some embodiments, the contact member includes a contact portion and a flexible layer, the contact portion is connected to the guide column, and the flexible layer is arranged around the contact surface of the contact portion; the outer peripheral surface of the contact member protrudes radially to form a holding portion.

[0024] In the above technical solution, a flexible layer is provided at the bottom of the contact piece, and the flexible layer is made of a flexible material, so that the contact piece is more comfortable in contact with the skin, which improves the patient's experience. In addition, a holding portion is formed on the outer peripheral surface of the contact piece in a radially protruding manner. When the detection piece moves upward and is in a separated state, the hand of the medical staff can hold the holding portion of the contact piece to hold and fix the contact piece, thereby avoiding the contact piece from being offset.

[0025] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Example The present application provides a novel device for detecting arterial pulsation and assisting arterial puncture. Figures 1 to 6 A novel arterial pulsation detection and arterial puncture assisting device 100 includes a handle 10, a detector 20 and a pulse detection assembly 30. The detector 20 is arranged at one end of the handle 10 in the length direction; the pulse detection assembly 30 includes a controller 31, a vibration sensor 32 and a prompt light 33. The vibration sensor 32 and the prompt light 33 are both electrically connected to the controller 31. The prompt light 33 and the controller 31 are both arranged on the handle 10. The vibration sensor 32 is arranged at the lower end of the detector 20 to detect the pulse signal after contacting the patient's skin; after the controller 31 receives the pulse signal from the vibration sensor 32 and the intensity of the pulse signal reaches a preset value, the controller 31 controls the prompt light 33 to send a prompt message.

[0035] In this solution, the handle 10 provides a gripping function, which is convenient for medical staff to contact the vibration sensor 32 on the probe 20 with the patient's skin and move it along the target area of ​​the patient's skin to find the pulse signal of the patient's artery. The setting of the prompt light 33, when the vibration sensor 32 detects the pulse beating signal, the controller 31 receives the pulse beating signal transmitted by the vibration sensor 32, and when the vibration sensor 32 detects that the intensity of the pulse beating signal reaches a preset value, the prompt light 33 will send out a time information to prompt the medical staff that the artery position is successfully located, and the current position contacted by the probe 20 is the patient's artery position, and then the probe 20 is removed, and the medical staff can puncture the artery at this position.

[0036] The controller 31 is a main command device that changes the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking and reversal of the motor. It is composed of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller 31. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system. The controller 31 can be a single-chip microcomputer.

[0037] The detection member 20 refers to a base structure for mounting the vibration sensor 32 , and the detection member 20 may be a cylindrical structure.

[0038] The indication information of the indicator light 33 can be various, depending on the actual situation. When the intensity of the pulse signal monitored by the vibration sensor 32 does not reach the preset value, the indicator light 33 can be in an off state. When the intensity of the pulse signal monitored by the vibration sensor 32 reaches the preset value, the indication information of the indicator light can be lit, flashing, etc.

[0039] Of course, when the indication light 33 is on, it can be divided into multiple situations, so as to better judge the positioning accuracy of the artery position.

[0040] In the present embodiment, the color of the warning light 33 may include green, yellow and red. The color switching of the warning light 33 may be determined according to the strength of the pulse signal. That is, when the strength of the pulse signal monitored by the vibration sensor 32 reaches the first preset value, the color of the warning light 33 is green. When the strength of the pulse signal monitored by the vibration sensor 32 reaches the second preset value, the color of the warning light is yellow. When the strength of the pulse signal monitored by the vibration sensor 32 reaches the third preset value, the color of the warning light 33 is red. The values ​​of the first preset value, the second preset value and the third preset value increase in sequence. Therefore, when the patient's physical condition is relatively weak, when the vibration sensor 32 monitors that the strength of the pulse signal reaches the second preset value, but cannot reach the third preset value, then the second preset value is used as the standard, the warning light 33 is lit and is in the yellow light state, and the current position of the artery where the detection member 20 contacts the patient's skin is the position of the artery. When the patient is in good physical condition, the vibration sensor 32 detects that the intensity of the pulse signal reaches the third preset value, the indicator light 33 lights up and is in a red state, and the current position where the detection element 20 contacts the patient's skin is the arterial blood vessel position.

[0041] Of course, in some embodiments, the novel arterial pulsation detection and arterial puncture assisting device 100 may further include a display screen 34, which is disposed on the handle 10 and is electrically connected to the controller 31. After receiving the pulse signal from the vibration sensor 32, the controller 31 may also display the pulse signal on the display screen 34. In this way, medical staff may obtain the patient's pulse strength information on the display screen 34, which is convenient for judging and understanding the patient's physiological condition, and judging whether the artery position is successfully located.

[0042] Therefore, medical staff can comprehensively judge the position of the artery according to the actual situation through the pulse signal on the display screen 34 and the prompt information of the prompt light 33. Medical staff have more reference basis for judgment, especially when the patient's physiological condition is relatively weak and the strength of the pulse signal always fails to reach the preset value of the prompt light 33. Compared with relying solely on the judgment of the prompt light 33, medical staff can also subjectively judge the pulse position according to the pulse signal strength value on the display screen 34. The application range of pulse detection is wider and the detection accuracy is higher.

[0043] The display screen 34 is a screen for displaying the pulse signal strength. The display screen 34 has a data processing unit, which can process the pulse data and display it on the display screen 34. The display screen 34 can be directly purchased and assembled, and no further details are given here. The vibration sensor 32 is a micro pressure sensor.

[0044] In some embodiments, the number of vibration sensors 32 is set to three, and the three vibration sensors 32 are evenly spaced along the circumference of the probe 20 at the detection end 21 of the probe 20 away from the handle 10. By setting the number of vibration sensors 32 to three, the position of the patient's artery can be monitored together by the three vibration sensors 32, and the position of the artery can be comprehensively analyzed and judged after the pulsation signals of the three vibration sensors 32 are obtained, with higher accuracy. In addition, the three vibration sensors 32 are evenly spaced along the circumference of the probe 20 at the detection end 21 of the probe 20 away from the handle 10, and the center of the area surrounded by the three vibration sensors 32 on the probe 20 is the location of the artery, and the position result of the artery detection is more accurate.

[0045] In the case of a display screen 34, the pulse information of the three vibration sensors 32 can be displayed on the display screen 34 independently, so that medical staff can comprehensively analyze the arterial position of the patient.

[0046] In some embodiments, the number of indicator lights 33 is equal to and corresponds to the number of vibration sensors 32. By making the number of vibration sensors 32 equal to and corresponding to the number of indicator lights 33, when all three indicator lights are lit and in the same state, it indicates that the position of the artery is successfully located. Compared with one vibration sensor 32, three vibration sensors 32 have a wider coverage range, a higher efficiency in locating the artery, and the three vibration sensors 32 cooperate with each other, so that the accuracy of locating the artery is also higher.

[0047] In some embodiments, the novel arterial pulsation detection and arterial puncture assisting device 100 further includes a guide post 40 and a contact member 50, wherein the guide post 40 is connected to the handle 10, the detection member 20 has a guide hole 22 for the guide post 40 to pass through, and the detection member 20 can be slidably mounted on the guide post 40; the contact member 50 is arranged at one end of the plurality of guide posts 40 away from the handle 10, the contact member 50 is cylindrical, and the contact member 50 has an avoidance hole 51 for avoiding the detection member 20, and a contact surface 52 for contacting the patient's skin; wherein the detection member 20 has a detection state and a separation state, when the detection member 20 is in the detection state, at least part of the detection member 20 is inserted into the contact member 50, and the detection end 21 of the detection member 20 is flush with the contact surface 52 of the contact member 50; when the detection member 20 is in the separation state, the detection member 20 is separated from the contact member 50, and there is a spacing between the detection end 21 of the detection member 20 and the contact member 50 to form an avoidance area 53 for arterial puncture.

[0048] After the probe 20 locates the artery, it is necessary to remove the probe 20 from the skin surface for the medical staff to perform arterial puncture. In fact, when the probe 20 locates the artery, the probe 20 squeezes the skin, which may cause the skin to be displaced and deformed to a certain extent. When the artery is successfully located, the probe 20 leaves the skin surface, and the skin resets after losing the squeezing effect of the probe 20, resulting in a certain deviation when the medical staff reads the artery position, and there is a problem of inaccurate puncture. Therefore, through the arrangement of the guide column 40 and the contact member 50, the probe 20 can be slidably arranged on the guide column 40. When the probe 20 is in the detection state, the contact surface 52 of the contact member 50 contacts the skin, at least part of the probe 20 is inserted in the contact member 50, and the detection end 21 of the probe 20 also contacts the skin surface, that is, the detection end 21 of the probe 20 and the contact member 50 contact the skin at the same time. When the probe 20 successfully locates the artery, the probe 20 switches from the detection state to the separation state, and the probe 20 slides upward along the guide column 40 away from the contact member 50. During the separation of the probe 20 from the skin surface, since the contact member 50 is always in contact with the skin surface, the contact member 50 presses on the skin area where the artery position is successfully located. Therefore, the artery position located during the separation of the probe 20 from the skin will not change. In addition, since there is a gap between the detection end 21 of the probe 20 and the contact member 50, a clearance zone 53 for arterial puncture is formed between the probe 20 and the contact member 50. The medical staff can directly penetrate the center of the contact member 50 from the clearance zone 53 to perform arterial puncture, and the puncture accuracy is high, which avoids the phenomenon that the medical staff's puncture accuracy is reduced after the probe 20 is separated from the skin.

[0049] The detection member 20 includes a body 24 and a detection portion 25. The detection portion 25 is smaller than the body 24 and is located at one side below the body 24. When the detection member 20 is in the detection state, the detection portion 25 of the detection member 20 is inserted into the contact member 50, and the body 24 is located outside the contact member 50.

[0050] In some embodiments, the number of guide posts 40 is set to two, and the two guide posts 40 are arranged opposite to each other. Since the medical staff need to insert the contact member 50 into the avoidance hole 51 area from the gap of the guide posts 40 during arterial puncture, the guide posts 40 will have a certain blocking effect on the arterial puncture of the medical staff. Therefore, the more the number of guide posts 40, the greater the impact on the arterial puncture of the medical staff. Therefore, by setting the number of guide posts 40 to two, the two guide posts 40 can not only ensure the stability of the detection member 20 during the up and down movement, but also will not cause interference with the arterial puncture, so that the medical staff can perform arterial puncture more conveniently.

[0051] In some embodiments, the novel arterial pulsation detection and arterial puncture assisting device 100 further includes a driving member 60, which is disposed on the handle 10, and the driving end of the driving member 60 is connected to the detection member 20, and the driving member 60 is used to drive the detection member 20 to slide along the guide column 40 to switch between the detection state and the separation state. Through the setting of the driving member 60, the driving member 60 can drive the detection member 20 to automatically switch between the detection state and the separation state, without the need for manual operation by medical staff, thereby reducing the workload of medical staff.

[0052] The handle 10 is equipped with a power module 35, which provides power to each component. The driving member 60 can be a miniature electric push rod, which is installed at the lower end of the handle 10. The driving member 60 is electrically connected to the controller 31. The top surface of the handle 10 is provided with a first operating button 12 for controlling the operation of the driving member 60 to switch the state of the detection member 20. The top surface of the handle 10 is also provided with a switch key 13 for controlling the start and stop of the auxiliary artery puncture device.

[0053] Of course, the edge of the lower end of the handle 10 can extend downward to form a cylindrical shield 11, the guide column 40 close to the handle 10 is located in the shield 11, and the electric push rod is installed in the shield 11. When the detection member 20 is in the separated state, at least part of the detection member 20 moves into the shield 11. The shield 11 can be made of a transparent material.

[0054] In addition, a detection light 23 may be provided at the middle position of the detection end 21 of the detection member 20. When the detection member 20 is in a separated state, the detection light 23 emits bright light toward the contact member 50 below, illuminating the contact member 50 and the skin area near the contact member 50, making it easier for medical staff to perform arterial puncture operations.

[0055] In some embodiments, the novel arterial pulsation detection and arterial puncture assisting device 100 further includes a disinfection component 70, which is used to spray disinfectant spray in the direction of the avoidance hole 51 of the contact piece 50; the disinfection component 70 includes a liquid storage box 71, a power component 72, a disinfection pipeline 73 and a nozzle 74, the liquid storage box 71 and the power component 72 are arranged on the handle 10, the liquid storage box 71 stores disinfectant, the nozzle 74 is arranged on the contact piece 50, and the power component 72 is used to provide power to transport the disinfectant in the liquid storage box 71 to the nozzle 74 through the disinfection pipeline 73 and spray it out from the nozzle 74. Since the patient needs to be disinfected during arterial puncture, the novel arterial puncture assisting device 100 for detecting arterial pulsation includes a disinfection component 70. When the detection needle successfully locates the artery and the detection needle is in a separated state, the disinfection component 70 can spray disinfectant spray in the direction of the avoidance hole 51 of the contact piece 50 to cover the patient's arterial skin with a layer of disinfectant. This facilitates the disinfection operation before arterial puncture, and does not require medical staff to perform large-area disinfection operations on the patient's skin in advance. Moreover, after the disinfectant is applied in advance, the disinfectant is liquid, which may have a certain impact on the positioning of the vibration sensor 32, and the disinfectant can easily damage the vibration sensor 32, affecting the service life of the vibration sensor 32.

[0056] Specifically, the liquid storage box 71 and the power component 72 are arranged on the handle 10. The liquid storage box 71 stores disinfectant. The power component 72 provides power to transport the disinfectant to the nozzle 74 in the contact piece 50. The nozzle 74 sprays the disinfectant spray in the direction of the avoidance hole 51. The disinfectant spray covers the patient's skin surface, completing the disinfection operation before arterial puncture.
