DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the automatic blood pricking and cupping device of the present invention is specifically described below in conjunction with embodiments and drawings.

[0029] <Example 1>

[0030] This embodiment describes in detail the structure, working principle and usage method of the automatic blood pricking and cupping device 100.

[0031] Figure 1 It is a schematic structural diagram of the automatic blood pricking and cupping device in Example 1 of the present invention.

[0032] like Figure 1 As shown, the automatic pricking blood sampling and cupping device 100 is used to perform pricking and cupping on patients, including a pricking device 10, a dirty blood collector 20, a control regulator 30, a wire 40, a catheter 50, a vacuum pump and a pressure sensor (the vacuum pump and the pressure sensor are not shown in the figure).

[0033] The pricking device 10 is used for pricking the acupuncture points of the patient, the dirty blood collector 20 is used for collecting the dirty blood produced by pricking, and the control regulator 30 is used for adjusting the depth of pricking.

[0034] The lancing device 10 is detachably connected to the dirty blood collector 20 , and the lancing device 10 is connected to the control regulator 30 via a wire 40 .

[0035] Wire 40 uses dual Type-C interfaces to achieve two-way information exchange and current conduction. Compared with 3.5mm connectors, it has better conductivity and can better meet the device's needs for conductivity and data transmission. It uses 30 / 22AWG multi-strand thick tinned copper wire cores, plus aluminum foil TPE outer sheath and other multi-layer shielding. The connector is made of aluminum alloy, and the wire body is made of high-strength nylon braiding, which is sturdy and durable. There are plugs at both ends of the wire 40.

[0036] The dirty blood collector 20 is connected to the vacuum pump via a conduit 50 , and a pressure sensor is connected to the conduit 50 for testing the pressure in the dirty blood collector 20 .

[0037] Figure 2 is a schematic structural diagram of the pricking device in Embodiment 1 of the present invention; Figure 3 is a schematic diagram of the internal structure of the pricking device in Example 1 of the present invention; Figure 4 It is a schematic structural diagram of the pricking needle mounting seat in Example 1 of the present invention.

[0038] like Figure 2-4 As shown, the puncture needle 10 includes a puncture needle housing 101, a connecting rod 102, a permanent magnet 103, a puncture needle mounting seat 104, an adjustment platform 105, a spring 106, an electromagnet 107, a spiral adjustment column 108, an adjustment motor 109, a laser rangefinder 110, and a signal transmission column 111.

[0039] The pricking device housing 101 is cylindrical, hollow inside, and has external threads at the bottom. The permanent magnet 103, the adjustment platform 105, the spring 106, the electromagnet 107, the spiral adjustment column 108, the adjustment motor 109, and the laser rangefinder 110 are all located inside the pricking device housing 101.

[0040] The lancing device housing 101 is made of PC material and coated with a conductive coating on the inside to minimize the weight of the lancing device 10 and achieve an electromagnetic shielding effect.

[0041] The top of the connecting rod 102 is fixedly connected to the permanent magnet 103, a part of which is located in the pricking device housing 101, and the other part extends out of the pricking device housing 101. The bottom of the extended part is installed with a pricking needle mounting seat 104 for mounting a pricking needle (shown in the figure). The material of the connecting rod 102 is a non-magnetizable material, such as a polymer material.

[0042] The connecting rod 102 passes through the circular hole on the housing bottom plate 1011 of the lancing device housing 101 and can move freely therein.

[0043] The bottom of the puncture needle mounting seat 104 has a plurality of assembly holes 1041 for mounting the puncture needle. In this embodiment, the puncture needle adopts a disposable blood collection needle, and the assembly hole 1041 cooperates with the disposable blood collection needle, and can be equipped with a plurality of disposable blood collection needles commonly used on the market.

[0044] The permanent magnet 103 is a strong NdFeB magnet with a diameter of 16 mm and a thickness of 5 mm, with a brand of N35, and a theoretical magnetic field strength of about 4000 Gs, and the specific magnetic field strength needs to be measured. The magnetic field generated by the permanent magnet 103 is a static magnetic field, and it decays very quickly after leaving the surface of the permanent magnet 103, and will not have adverse effects on the human body.

[0045] The aperture of the adjustment platform 105 is larger than the diameter of the connecting rod 102 , and the adjustment platform 105 is passed through the connecting rod 102 and can move up and down along the connecting rod 102 .

[0046] The spring 106 is also inserted on the connecting rod 102, one end of which is fixedly connected to the permanent magnet 103, and the other end of which is fixedly connected to the adjustment platform 105. The material of the spring 106 is spring steel, and the outer diameter is smaller than the diameter of the permanent magnet 103. The specific parameters are: outer diameter 15mm, length 25mm, wire diameter 1mm. In the non-piercing state, the distance between the permanent magnet 103 and the adjustment platform 105 is equal to the original length of the spring 106.

[0047] The electromagnet 107 is located above the permanent magnet 103, and the original distance between the two is 0mm-5mm. After the adjustment of the motor 109, the two can contact each other. After power is turned on, an instantaneous magnetic field with the same polarity as the permanent magnet 103 at the lower end is generated, and the same polar repulsion of the magnetic field causes the permanent magnet 103 to move downward, driving the connecting rod 102 to compress the spring under the action of the repulsive force and move downward by a corresponding length to complete the pricking. After the pricking is completed, the permanent magnet 103 returns to the original position.

[0048] Theoretically, the magnetic field generated by the electromagnet 107 should not exceed 3000Gs, and can be slightly increased as needed. Considering the distance between the electromagnet 107 and the human body and the impact time, the impact of the magnetic field intensity on human health is also minimal.

[0049] The adjusting motor 109 is used to drive the spiral adjusting column 108 to rotate, and the lower part is fixedly connected to the electromagnet 107. A first gear is fixed on the output end of the adjusting motor 109, and a second gear is fixed on the top of the spiral adjusting column 108, and the two gears are meshed. The lower end of the spiral adjusting column 108 is threadedly connected to the adjusting platform 105. The adjusting platform 105 has a threaded hole.

[0050] The spiral adjusting column 108 rotates around its own axis under the drive of the adjusting motor 109 so that the threaded hole rises or falls along the spiral adjusting column 108, thereby driving the adjusting platform 105 to move along the connecting rod 102. Since the adjusting platform 105 is fixedly connected with the spring 106, when the adjusting platform 105 rises, the spring 106 is compressed, and the spring 106 lifts the permanent magnet 103, so that the height of the pricking needle mounting seat 104 from the skin is increased, thereby reducing the depth of the pricking needle piercing the skin. Similarly, when the spiral adjusting column 108 rotates in the opposite direction, the adjusting platform 105 descends, the spring 106 stretches, and the permanent magnet 103 is pulled down, so that the height of the pricking needle mounting seat 104 from the skin is reduced, thereby increasing the depth of the pricking needle piercing the skin.

[0051] The adjustment motor 109 uses a 10mm micro stepper motor with a motor diameter of 10mm and a step angle of 18°. The outer diameter of the two gears is 10mm, the number of teeth is 20, the tooth module is 0.45, the total length of the spiral adjustment column 108 is 40mm, and the total number of turns is 10 turns. Each time the micro stepper motor steps, the spiral adjustment column 108 rises 0.2mm, and at the same time, the adjustment platform 105 rises 0.2mm, and the same applies to the descent.

[0052] The laser rangefinder 110 is disposed on the housing bottom plate 1011 at the bottom of the lancing device housing 101 and is connected to the signal transmission column 111 through a wire for measuring the distance between the blood collection needle and the patient's skin surface.

[0053] The laser rangefinder 110 can monitor the distance between the puncture device and the skin below it in real time. When there is excessive bleeding and the skin is covered with a layer of dirty blood, the data monitored by the laser rangefinder 110 is the distance between the puncture device and the dirty blood on the skin. When the height of the blood exceeds the set threshold, that is, the distance between the puncture device and the blood is reduced to the set value, the buzzer on the control regulator 30 will sound.

[0054] The bottom end of the signal transmission column 111 is fixedly connected to the upper part of the regulating motor 109, and the top end passes through the upper end of the lancing device housing 101 and extends to the outside of the lancing device housing 101, and then is connected to the control regulator 30 through the wire 40. The signal transmission column 111 has a socket that matches the socket of the wire 40.

[0055] The adjusting platform 105 and the electromagnet 107 are each provided with a through hole 112 for the wires connecting the laser rangefinder 110 and the signal transmission column 111 to pass through.

[0056] Figure 5 is a schematic structural diagram of a tank body of a dirty blood collector in Example 1 of the present invention; Figure 6 It is a schematic diagram of the structure of the dirty blood absorption ring in Example 1 of the present invention.

[0057] like Figure 5 , 6 As shown, the dirty blood collector 20 includes a tank body 201 and a dirty blood absorption ring 202 engaged on the inner wall of the tank body 201 .

[0058] The top of the tank body 201 has an internal thread that matches the external thread of the lancing device housing, and the two cooperate to make the lancing device housing 101 and the tank body 201 detachably connected. A soft rubber pad can be added to the connection between the two to ensure sealing.

[0059] The lower part of the bottom end of the tank body 201 has a tenon 2011 protruding outward. The tank body 201 is also provided with a conduit connection hole 2012.

[0060] Figure 7 It is a schematic diagram of the structure of the catheter in Example 1 of the present invention.

[0061] like Figure 1 , 6 As shown in FIG. 7 , the catheter 50 is made of a flexible plastic material with a certain rigidity, the aperture of one end matches the catheter connection hole 2011 , and the other end matches the socket of the vacuum pump.

[0062] like Figure 6 As shown, the outer diameter of the dirty blood absorption ring 202 is equal to or slightly larger than the inner diameter of the tank body 201 . At the same time, the inner diameter of the dirty blood absorption ring 202 is larger than the outer diameter of the puncture needle mounting seat 104 , and can be stuck on the inner wall of the tank body 201 without affecting the normal operation of the puncture needle mounting seat 104 .

[0063] The dirty blood absorption ring 202 is a circular ring made of a transparent material, and a plurality of evenly distributed capillary holes 2021 are arranged inside the circular ring, and the capillary holes 2021 penetrate the circular ring along the axial direction of the circular ring.

[0064] The outer surface of the blood absorption ring 202 is printed with a height scale to facilitate the calculation of the amount of bleeding. Through the integration of clinical data, three blood absorption rings 202 with different specifications and blood absorption amounts are designed:

[0065] 3ml: Number of layers: single layer, capillary diameter 1mm, height 60mm, number 70;

[0066] 5ml: Number of layers: single layer, capillary diameter 1mm, height 60mm, number 110;

[0067] 10ml: Number of layers: double layers, outer layer: capillary diameter 1mm, height 60mm, quantity 110, inner layer: capillary diameter 1mm, height 60mm, quantity 100.

[0068] Figure 8 is a schematic diagram of the structure of the control regulator in Example 1 of the present invention; Fig. 9 It is a schematic diagram of the structure of the control regulator in embodiment 1 of the present invention from another angle.

[0069] like Figure 8 , 9 As shown, the control regulator 30 includes a housing 301 , a control chip disposed in the housing 301 , a buzzer electrically connected to the control chip, and a display screen 302 and a plurality of adjustment buttons 303 disposed on the housing 301 .

[0070] A vacuum pump and a pressure sensor are installed in the housing 301. An air extraction hole 3011 is provided on the rear side of the housing 301, and the conduit 50 connects the vacuum pump with the tank body 201 through the air extraction hole 3011. At the same time, the conduit 50 is connected with the pressure sensor, and the negative pressure in the tank body 201 can be monitored in real time.

[0071] The pressure sensor is electrically connected to the signal transmission column 111 to transmit the measured pressure data to the control chip in real time.

[0072] When the amount of bleeding exceeds the threshold, the control chip sends a command to the buzzer, and the buzzer sounds an alarm.

[0073] The housing 301 also has an electrical jack 304 for the wire 40 to be inserted into, so that the signal transmission column 111 can both transmit data to the control chip and receive instructions from the control chip.

[0074] The housing 301 is also provided with a plurality of adjustment buttons, such as a pressure adjustment button (+), a pressure adjustment button (-), a time adjustment button (+), a time adjustment button (-), a blood sampling volume adjustment button (+), and a blood sampling volume adjustment button (-). Among them, (+) indicates increasing the pressure, and (-) indicates decreasing the pressure.

[0075] The control chip has a storage unit, a calculation unit and an instruction unit.

[0076] The storage unit is used for the user to input preset parameters and store the preset parameters input by the user, including cupping time, negative pressure during cupping, bleeding alarm threshold, inner diameter of the dirty blood absorption ring, model of the dirty blood absorption ring, etc. The storage unit is also used to store the height of bleeding measured by the laser rangefinder 110, the distance between the blood collection needle and the skin surface of the patient, and the pressure value measured by the pressure sensor.

[0077] The computing unit performs calculations based on the data in the storage unit and transmits the data to the instruction unit, which then issues corresponding instructions.

[0078] The working principle of the automatic blood collection and cupping device is:

[0079] When performing the cupping operation, fit the appropriate dirty blood absorption ring into the cup body, and then buckle the dirty blood collector at the treatment position. In the initial state, the distance between the lowest part of the lancet and the skin is 3 cm. After the disposable blood collection needle is inserted, the needle tip is 2 cm away from the skin. The laser rangefinder first measures the distance between the blood collection needle and the skin, transmits the data to the control chip through a wire, and then enters the preset parameters in the control regulator, including the cupping time, the negative pressure during cupping, and the bleeding alarm threshold. These data will be displayed on the display.

[0080] After the computing unit of the control chip calculates the distance signal transmitted by the laser rangefinder, it obtains the height that needs to be adjusted and sends instructions to the instruction unit. The instruction unit transmits the instructions to the signal transmission column through a wire. The signal transmission column instructs the stepper motor to move and drives the spiral adjustment column to automatically adjust the height of the adjustment platform, thereby adjusting the pricking depth.

[0081] After the height adjustment is completed, the electromagnet is energized for 1 second through the signal transmission column to generate an instantaneous magnetic field that repels the permanent magnet. The repulsive force of the same poles of the magnetic field causes the permanent magnet and the connecting rod and pricking needle mounting seat connected to it to overcome the elastic force of the spring and move downward, and the magnetism disappears. After the spring reaches the limit compression distance, the connecting rod and the pricking needle mounting seat stop moving downward, and then under the action of the elastic force of the spring, they quickly rebound and return to the initial state, completing a pricking process.

[0082] After the pricking is completed, the control chip storage unit receives the pricking completion signal, starts the vacuum pump to pump negative pressure, and the pressure sensor measures the negative pressure in the dirty blood collector and cooperates with the vacuum pump for precise control. After the blood flows out, it contacts the capillary of the dirty blood absorption ring in the tank. The blood automatically flows into the dirty blood absorption ring against gravity due to the capillary phenomenon. If the patient bleeds a lot and exceeds the set threshold, the laser rangefinder monitors the height of the overflowed blood in real time and performs simple calculations. Once the overflowed blood level exceeds the preset height, the negative pressure will be reduced and a sound will beep to remind the operator.

[0083] Function and Effect of Example 1

[0084] According to the automatic pricking blood collection and cupping device provided by the present embodiment, since the top of the connecting rod has a permanent magnet, the bottom has a pricking needle mounting seat for installing the pricking needle, the spring and the adjustment platform are both arranged on the connecting rod, and the two ends of the spring are respectively fixedly connected with the permanent magnet and the adjustment platform, and the electromagnet is arranged above the permanent magnet, so when the electromagnet generates a magnetic field to push the permanent magnet to move downward, the connecting rod and the pricking needle mounting seat move downward synchronously to complete the automatic pricking, and when the magnetic field disappears, the elastic force of the spring makes the permanent magnet, the connecting rod and the pricking needle mounting seat move upward synchronously, and automatically return to the initial position, which is convenient for the next pricking. In addition, the regulating motor drives the spiral regulating column to rotate, driving the adjusting platform to rise or fall along the connecting pipe, and under the elastic force of the spring, the permanent magnet drives the connecting rod to move synchronously, so the depth of pricking can be adjusted. In addition, the control regulator is connected to the signal transmission column and the regulating motor for communication, and the lifting distance of the regulating platform can be controlled according to the distance between the blood collection needle and the patient's body to control the pricking depth. Therefore, the device can automatically adjust and accurately position the pricking depth according to pre-set parameters. After the height adjustment is completed, the electromagnet is automatically energized to complete automatic pricking. It has the advantages of being simple, standardized, and integrating automatic blood collection and cupping.

[0085] The dirty blood absorption ring of the device is made of transparent resin material and is replaced after use to avoid unnecessary cross infection. The dirty blood absorption ring can move upward in the cup as the skin bulges during cupping and always fits on the skin. During cupping, dirty blood flows to the cup wall and contacts the capillaries of the dirty blood absorption ring. Due to the capillary phenomenon, it enters the dirty blood absorption ring against gravity, and the amount of bleeding can be calculated according to the volume and number of capillaries, so that the amount of bleeding can be quantified. The amount of bleeding can also be controlled with a laser rangefinder. When the amount of bleeding overflows the maximum absorption range of the dirty blood absorption ring, the height of the overflowed blood in the cup is measured and calculated, and compared with the pre-set parameters, the negative pressure in the cup is reduced and the operator is reminded by sound.

[0086] The pricking needle installed in the device is a disposable blood collection needle, which is low in cost and easy to replace after use, making the pricking process safer and more hygienic.

[0087] The device also has a vacuum pump and a negative pressure sensor, which enables real-time monitoring and control of the pressure inside the tank.

[0088] <Example 2>

[0089] The automatic blood pricking and cupping device in this embodiment has the structure of the automatic blood pricking and cupping device in Example 1, and further has a silicone ring 60 .

[0090] The silicone ring 60 can fit the skin well and has a mortise and tenon groove 601, which cooperates with the tenon at the lower part of the tank body to fix the silicone ring to the lower end of the tank body.

[0091] When cupping joints or other areas that are difficult to cupping, disinfecting the area around the cupping area with iodine will help the silicone ring fit tightly.
