Description

Technical Field

[0001] The present application relates to the technical field of blood drawing devices, and in particular to a visually automatically separated Y-shaped blood drawing device. Background Art

[0002] In clinical practice, blood gas and other blood are always separated, especially for patients with septic shock, blood culture may even be required. In the ICU, there is an arterial monitoring device that can draw all blood at once. However, in ordinary wards, patients do not have arterial detection devices. At this time, blood drawing must be done twice, once for arterial blood and once for venous blood. For convenience and to reduce the pain of patients, the existing technology usually chooses to draw blood once by pricking the artery.

[0003] But there are also problems: currently, arterial blood is drawn clinically, and arterial puncture is performed more by touch, anatomical position, and experience. However, when the patient has a fast heart rate and a weak and rapid arterial pulsation, the artery is not easy to be visible, resulting in a high failure rate of arterial puncture. In order to solve this technical problem, the present application provides a visual and automatically separated Y-shaped blood collection device. Summary of the invention

[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide a visual and automatically separated Y-shaped blood collection device to solve the technical problem in the existing technology of low success rate of arterial puncture when the patient has a fast heart rate, a weak and rapid arterial pulsation, and the artery is not easy to show during the blood collection process.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: a visual and automatically separated Y-shaped blood collection device, comprising a visualization device, a marking device and a blood collection device, the visualization device comprising an arc-shaped buckle strip and an arc-shaped connecting strip vertically fixedly connected to the middle part of the arc-shaped buckle strip, one end of the arc-shaped buckle strip is provided with an infrared light source for irradiating human skin, and the end of the arc-shaped connecting strip away from the arc-shaped buckle strip is equipped with a miniature camera for collecting reflected light from the infrared light source, the miniature camera signal is connected to a DSP module installed inside the arc-shaped connecting strip, the marking device is used to mark the arterial path displayed by the visualization device, and the blood collection device is used to collect blood according to the mark.

[0006] By adopting the above technical solution, when collecting arterial blood from a patient, the doctor places the two ends of the arc-shaped buckle strip on the back of the ear, so that the arc-shaped connecting strip is buckled behind the doctor's head and the micro-camera is located on the doctor's forehead. Then the infrared light source and the micro-camera are started. The infrared light source illuminates the skin to reflect the vascular skin tissue with different pigments. The micro-camera collects images of the blood vessels and skin tissue and sends them to the DSP module. The DSP module processes the collected analog signals of the blood vessels and converts them into appropriate digital signals, that is, the blood vessels are highlighted from the overall image and sent to the micro-camera. The micro-camera projects the final blood vessel image onto the skin, so that the doctor can accurately find the artery. The doctor then uses a marking device to mark the arterial path, and then uses a blood sampling device to collect blood according to the mark, so that the doctor can accurately find the artery for blood sampling, making it more convenient and accurate for the doctor to collect arterial blood.

[0007] Furthermore, the marking device includes a quadrilateral marking body, a through hole penetrating the marking body is opened in the middle of the upper surface of the marking body, openings penetrating the marking body are opened on the circumferential surface of the lower end of the marking body, a cross marking plate is arranged in the through hole, the four ends of the cross marking plate extend out of the marking body through the openings, an infrared rangefinder is installed on the upper surface of the cross marking plate, the infrared rangefinder signal is connected to a display installed on the body, a dye strip is fixedly provided on the bottom surface of the cross marking plate, a detection port penetrating the cross marking plate is opened in the middle of the cross marking plate, the output end of the infrared rangefinder is emitted through the detection port, and the dye strip is arranged around the detection port.

[0008] By adopting the above technical solution, the marking body is placed on the arterial path, so that the infrared rangefinder is irradiated on the skin, and the infrared rangefinder sends the distance signal from the cortex to the artery to the display, and the display displays the data. At this time, the dye strip is pressed on the skin, so that a cross pattern with a hole is printed on the skin, and the marking is completed. The doctor inserts a needle from the hole of the cross pattern, so that the doctor can accurately find the artery for blood collection.

[0009] Furthermore, the blood collection device includes a needle, a needle tube connected to the needle, and a Y-shaped tube installed at the end of the needle tube away from the needle, the Y-shaped tube includes a left pipe and a right pipe, the outlet of the right pipe is plugged with a pipe plug, the outlet of the left pipe is connected to a reagent tube, and tube clamps are provided on the outer side of one end of the left pipe close to the needle tube and the outer side of one end of the right pipe close to the needle tube.

[0010] By adopting the above technical scheme, first use a tube clamp to clamp the left pipeline, then pull out the tube plug to connect the right pipeline to the reagent tube, and then insert a needle according to the marked position, so that the arterial blood flows into the right pipeline through the needle tube, and then flows into the reagent tube through the right pipeline. The setting of the left pipeline is for different situations. When it is necessary to draw arterial blood for arterial testing and arterial blood for venous testing from the patient at the same time, the left pipeline can be clamped with a tube clamp first, and then the tube plug can be pulled out to connect the right pipeline to the reagent tube, and then the needle is inserted into the arterial blood vessel to draw arterial blood for arterial testing (generally, arterial blood can replace venous blood for testing). After the arterial blood for arterial testing is drawn, the right pipeline is clamped with a tube clamp, and then the tube clamp on the left pipeline is removed, and the left pipeline is connected to the reagent tube, and then arterial blood for venous testing is drawn, so that the doctor can collect the required blood at one time through the blood sampling device.

[0011] Furthermore, an automatic separation device is provided at one end of the left pipeline away from the needle tube to facilitate the left pipeline to separate from the reagent tube.

[0012] Furthermore, the automatic separation device includes a fixed plate fixedly connected to the left pipe, a movable plate sleeved on the left pipe, and a separation button passing through the fixed plate and abutting against the movable plate. The movable plate is located at the outlet of the left pipe, and the separation button is plugged into the fixed plate.

[0013] By adopting the above technical solution, after the needle punctures the artery, due to a certain needle insertion angle, one hand must be used to continuously fix the needle. If it is not continuously fixed, the needle will slide, causing the needle to leave the marked area, which will increase the patient's discomfort when the doctor replaces the reagent tube to draw blood and may also increase the blood collection failure rate. The setting of the automatic separation device solves this technical problem. The doctor inserts the outlet of the left pipeline into the reagent tube, so that the movable plate moves to the attached fixed plate. After drawing a tube of blood, when the reagent tube needs to be replaced, the doctor holds the left and right ends of the fixed plate with two fingers, and then pushes the separation button with the thumb to make the movable plate attached to the reagent tube and apply pressure to the reagent tube, and pulls the fixed plate to separate the left pipeline from the reagent tube. In this way, the doctor can hold the needle with one hand and replace the reagent tube with the other hand, making it more convenient for the doctor to replace the reagent tube during blood drawing.

[0014] Furthermore, a scale is engraved on the needle.

[0015] By adopting the above technical solution, the doctor can judge the insertion distance of the needle according to the data displayed by the marking device. The setting of the scale can enable the doctor to observe the insertion distance of the needle more clearly, thereby preventing the doctor from over-puncturing and improving the doctor's tolerance for acupuncture.

[0016] Furthermore, a fixing adhesive is fixedly provided on the outer side of the left pipe.

[0017] By adopting the above technical solution, after the doctor completes the acupuncture, the left pipeline is fixed and adhered to the patient's skin to prevent movement.

[0018] Furthermore, a circular handle is fixedly provided on one side of the syringe.

[0019] By adopting the above technical solution, the circular handle enables the doctor to choose the pen-holding style or butterfly-wing style puncture technique according to his or her own habits.

[0020] Furthermore, two oppositely arranged connecting plates are respectively provided on the left and right sides of the back side of the micro camera, and one end of the arc-shaped connecting strip away from the arc-shaped buckle strip is located between the two connecting plates and is rotatably connected to the connecting plates. A fixing structure for fixing the micro camera is provided on the micro camera, and the fixing structure includes a fixing rod with one end rotatably connected to the upper end of the micro camera and the other end abutting against the arc-shaped connecting strip, and an abutment interface provided on the arc surface of the arc-shaped connecting strip. A plurality of abutment interfaces are provided and are arranged along the shape of the arc-shaped connecting strip. The fixing rod is in the shape of a figure 7, and its shorter end abuts against the abutment interface.

[0021] By adopting the above technical solution, although the setting of the marking device can enable the doctor to accurately find the artery for blood collection, and although the doctor can clearly display the arterial path by wearing a visualization device and looking down from the top of the skin, the marking device blocks the skin when using the marking device for marking. Although the doctor can observe part of the arterial path through the opening of the marking device, it is still possible to mark the wrong place. The rotating miniature camera solves this technical problem. When marking the skin, the doctor can place one side of the marking device on the skin, and then tilt the marking device. The doctor then pushes the fixing rod to rotate the miniature camera. When the miniature camera is rotated to the point where it can project the skin arterial path, the shorter end of the fixing rod is abutted against the abutment interface, and then the doctor can observe the arterial path more clearly, and then press the other side of the marking device down onto the patient's skin, so that the doctor can accurately mark the arterial path.

[0022] Furthermore, a return spring is provided between the bottom surfaces of the four openings and the bottom surfaces of the four ends of the cross mark plate, one end of the return spring is fixedly connected to the cross mark plate, and the other end is fixedly connected to the mark body.

[0023] By adopting the above technical solution, although the setting of the marking device can enable the doctor to accurately find the artery for blood collection, due to the weight of the infrared rangefinder, the dyeing strip on the bottom surface of the cross mark plate always extends out of the marking body, so that the doctor may rub the dyeing strip when using the marking body, which reduces the service life of the dyeing strip and causes the doctor's skin or clothes to be stained with the color of the dyeing strip, which is very inconvenient. The setting of the reset spring solves this technical problem. The reset spring pushes the cross mark plate and rises along the height of the marking body, so that the dyeing strip retracts into the marking body, preventing the chromosome from consuming its service life when not in use, and preventing the dyeing strip from rubbing against the doctor's skin or clothes. When the dyeing strip needs to be used, the part of the cross mark plate extending out of the marking body is pushed downward, so that the cross mark plate presses the reset spring and moves downward, so that the dyeing strip extends out of the marking body. After marking is completed, the cross mark plate is released, and the cross mark plate is rebounded by the reset spring. The setting of the reset spring can also prevent the cross mark plate from shaking disorderly in the marking body, and prevent the infrared rangefinder from being damaged by the shaking of the cross mark plate during the transportation of the marking device.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. Through the setting of the visualization device, when collecting arterial blood from the patient, the doctor puts the two ends of the arc buckle strip on the back of the ear, so that the arc connecting strip is buckled behind the doctor's head and the micro camera is located on the doctor's forehead. Then the infrared light source and the micro camera are started. The infrared light source illuminates the skin to reflect the blood vessels and skin tissues with different pigments. The micro camera collects images of blood vessels and skin tissues and sends them to the DSP module. The DSP module processes the collected analog signals of the blood vessels and converts them into appropriate digital signals, that is, the blood vessels are highlighted from the overall image and sent to the micro camera. The micro camera projects the final blood vessel image onto the skin, so that the doctor can accurately find the purpose of the artery.

[0026] 2. Through the setting of the marking device, it is realized to place the marking body on the arterial path, so that the infrared rangefinder is irradiated on the skin, and the infrared rangefinder sends the distance signal from the cortex to the artery to the display, and the display shows the data. At this time, the dye strip is pressed on the skin, so that a cross pattern with holes is printed on the skin, and the marking is completed. The doctor inserts the needle from the hole of the cross pattern, so that the doctor can accurately find the artery for blood collection.

[0027] 3. Through the setting of the blood sampling device, it is achieved that the left pipeline is first clamped with a tube clamp, and then the tube plug is pulled out to connect the right pipeline to the reagent tube, and then the needle is inserted according to the marked position, so that the arterial blood flows into the right pipeline through the needle tube, and then flows into the reagent tube through the right pipeline. The setting of the left pipeline is for different situations. When it is necessary to draw arterial blood for arterial testing and arterial blood for venous testing from the patient at the same time, the left pipeline can be clamped with a tube clamp first, and then the tube plug is pulled out to connect the right pipeline to the reagent tube, and then the needle is inserted into the arterial blood vessel to draw arterial blood for arterial testing (under normal circumstances, arterial blood can replace venous blood for testing). After the arterial blood for arterial testing is drawn, the right pipeline is clamped with a tube clamp, and then the tube clamp on the left pipeline is removed, and the left pipeline is connected to the reagent tube, and then arterial blood for venous testing is drawn, so that the doctor can collect the required blood at one time through the blood sampling device.

[0033] The present application is further described in detail below in conjunction with the accompanying drawings.

[0034] Example, see Figure 1 - Figure 4A visual automatically separated Y-shaped blood sampling device comprises a visualization device 1, a marking device 2 and a blood sampling device 3. The visualization device 1 comprises an arc buckle strip 10 and an arc connecting strip 11 vertically fixedly connected to the middle of the arc buckle strip 10. An infrared light source 12 for irradiating human skin is arranged at one end of the arc buckle strip 10. A micro camera 13 for collecting reflected light of the infrared light source 12 is installed at one end of the arc connecting strip 11 away from the arc buckle strip 10. The micro camera 13 is signal-connected to a DSP module installed inside the arc connecting strip 11. The marking device 2 is used to mark the arterial path displayed by the visualization device 1. The blood sampling device 3 is used to collect blood according to the mark. The marking device 2 comprises a quadrilateral marking body 20 and a marking body 20. A through hole penetrating the marking body 20 is provided in the middle of the surface, and openings 21 penetrating the marking body 20 are provided on the circumference of the lower end of the marking body 20. A cross mark plate 22 is provided in the through hole, and the four ends of the cross mark plate 22 extend out of the marking body 20 through the opening 21. An infrared rangefinder 23 is installed on the upper surface of the cross mark plate 22, and the signal of the infrared rangefinder 23 is connected to a display 24 installed on the marking body 20. A dye strip 25 is fixedly provided on the bottom surface of the cross mark plate 22. A detection port 27 penetrating the cross mark plate 22 is provided in the middle of the cross mark plate 22, and the output end of the infrared rangefinder 23 is emitted through the detection port 27. The dye strip 25 is arranged around the detection port 27. The blood collection device 3 includes a needle 30, a needle tube 31 connected to the needle 30, and a display 24 installed in the cross mark plate 22. The needle tube 31 is away from the end of the needle 30, and the Y-shaped tube 32 includes a left pipe 320 and a right pipe 321. The outlet of the right pipe 321 is plugged with a pipe plug 322, and the outlet of the left pipe 320 is connected to a reagent tube 33. The outer side of the end of the left pipe 320 close to the needle tube 31 and the outer side of the end of the right pipe 321 close to the needle tube 31 are both provided with a pipe clamp 34. When collecting arterial blood from a patient, the doctor puts the two ends of the arc buckle strip 10 on the back of the ear, so that the arc connecting strip 11 buckles the doctor's head and the micro camera 13 is located on the doctor's forehead, and then starts the infrared light source 12 and the micro camera 13. The infrared light source 12 irradiates the skin to reflect blood vessels and skin tissues of different pigments, and the micro camera 13 collects images of blood vessels and skin tissues. The DSP module processes and converts the collected analog signals of the blood vessels into appropriate digital signals, that is, the blood vessels are highlighted from the overall image and sent to the micro camera 13. The micro camera 13 projects the final blood vessel image onto the skin, so that the doctor can accurately find the artery. Then the marking body 20 is placed on the arterial path, so that the infrared rangefinder 23 is irradiated on the skin. The infrared rangefinder 23 sends the distance signal from the cortex to the artery to the display 24, and the display 24 displays the data. At this time, the dye strip 25 is pressed on the skin, so that a cross pattern with holes is printed on the skin. The marking is completed, and then the left pipe 320 is clamped with the pipe clamp 34, and then the pipe plug 322 is pulled out to connect the right pipe 321 to the reagent tube 33.Then, the needle 30 is inserted according to the marked position, so that the arterial blood flows into the right pipeline 321 through the needle tube 31, and then flows into the reagent tube 33 through the right pipeline 321, so that the doctor can accurately find the artery for blood collection. The setting of the left pipeline 320 is for different situations. When it is necessary to draw arterial blood for arterial testing and venous testing from the patient at the same time, the left pipeline 320 can be clamped with the tube clamp 34 first, and then the tube plug 34 is pulled out to connect the right pipeline 321 to the reagent tube 33, and then the needle 30 is inserted into the artery to draw arterial blood for arterial testing. After the arterial blood for arterial testing is drawn, the right pipeline 320 is clamped with the tube clamp 34, and then the tube clamp 34 of the left pipeline 320 is removed, and the left pipeline is connected to the reagent tube 33, and then arterial blood for venous testing is drawn, so that the doctor can collect the required blood at one time through the blood sampling device 3.

[0035] Although the setting of the marking device 2 can enable the doctor to accurately find the artery for blood collection, and although the doctor can clearly display the arterial path by wearing the visualization device 1 and looking down from above the skin, the marking device 2 blocks the skin when marking with the marking device 2. Although the doctor can observe part of the arterial path through the opening of the marking device 2, it is still possible to mark the wrong place. In order to solve this technical problem, the present embodiment provides two relatively arranged connecting plates 14 on the left and right sides of the back of the micro camera 13, respectively. The end of the arc-shaped connecting strip 11 away from the arc-shaped buckle strip 10 is located between the two connecting plates 14 and is rotatably connected to the connecting plate 14. The micro camera 13 is provided with a fixing structure 5 for fixing the micro camera 13, and the fixing structure 5 includes one end rotatably connected to the micro camera The upper end of the camera 13 and the other end abut against the fixed rod 50 on the arc-shaped connecting strip 11 and the abutment port 51 provided on the arc surface of the arc-shaped connecting strip 11. The abutment port 51 is provided in multiple numbers and is arranged along the shape of the arc-shaped connecting strip 11. The fixed rod 50 is in a 7-shape, and its shorter end abuts against the abutment port 51. When the doctor marks the skin, he can place one side of the marking device 2 on the skin, and then lift the marking device 2. The doctor then pushes the fixed rod 50 to rotate the micro camera 13. When the micro camera 13 is rotated to the point where the skin artery path can be projected, the shorter end of the fixed rod 50 abuts against the abutment port 51. The doctor can then observe the arterial path more clearly, and then press the other side of the marking device 2 down onto the patient's skin, so that the doctor can accurately mark the arterial path.

[0036] Although the setting of the marking device 2 enables the doctor to accurately find the artery for blood sampling, the weight of the infrared rangefinder 23 causes the dye strip 25 on the bottom surface of the cross marking plate 22 to extend out of the marking body 20, so that the doctor may rub the dye strip 25 when using the marking body 20, which reduces the service life of the dye strip 25 and causes the doctor's skin or clothes to be stained with the color of the dye strip 25, which is very inconvenient. In order to solve this technical problem, in this embodiment, a return spring 26 is provided between the bottom surfaces of the four openings 21 and the bottom surfaces of the four ends of the cross marking plate 22. One end of the return spring 26 is fixedly connected to the cross marking plate 22, and the other end is fixedly connected to the marking body 20. The return spring 26 presses against the cross marking plate 22. As the staining strip 25 rises along the height of the marking body 20, it retracts into the marking body 20 to prevent the staining strip 25 from consuming its service life when not in use, and at the same time prevents the staining strip 25 from rubbing against the doctor's skin or clothes. When the staining strip 25 is needed, the cross mark plate 22 is pushed downward at the position where it extends out of the marking body 20, so that the cross mark plate 22 presses the reset spring 26 and moves downward, so that the staining strip 25 extends out of the marking body 20. After marking is completed, the cross mark plate 22 is released, and the cross mark plate 22 is rebounded by the reset spring 26. The setting of the reset spring 26 can also prevent the cross mark plate 22 from shaking disorderly in the marking body 20, and prevent the infrared rangefinder 23 from being damaged by collision due to the shaking of the cross mark plate 22 during the transportation of the marking device 2.

[0037] In this embodiment, an automatic separation device 4 is provided at one end of the left pipeline 320 away from the needle tube 31, which is convenient for the left pipeline 320 to be separated from the reagent tube 33. The automatic separation device 4 includes a fixed plate 40 fixedly connected to the left pipeline 320, a movable plate 41 sleeved on the left pipeline 320, and a separation button 42 passing through the fixed plate 40 and abutting against the movable plate 41. The movable plate 41 is located at the outlet of the left pipeline 320, and the separation button 42 is plugged into the fixed plate 40. Because after the needle 30 punctures the artery, there is a certain needle insertion angle, and one hand is required to continuously fix the needle 30. If it is not continuously fixed, the needle 30 will slide, causing the needle 30 to be separated from the marked area, which will increase the patient's discomfort when the doctor replaces the reagent tube 33 to draw blood, and may also increase the blood collection failure rate. The setting of the automatic separation device 4 solves this technical problem. The doctor can fix the left The outlet of the pipe 320 is inserted into the reagent tube 33, so that the movable plate 41 moves to be attached to the fixed plate 40. After drawing a tube of blood, when the reagent tube 33 needs to be replaced, the doctor holds the left and right ends of the fixed plate 40 with two fingers, and then pushes the separation button 42 with the thumb to make the movable plate 41 attached to the reagent tube 33 and exert pressure on the reagent tube 33, and pulls the fixed plate 40 to separate the left pipe 320 from the reagent tube 33. In this way, the doctor can hold the needle 30 with one hand and replace the reagent tube 33 with the other hand, making it more convenient for the doctor to replace the reagent tube 33 during blood drawing. The automatic separation device 4 is set on the left pipe 320 because the left pipe 320 needs to connect multiple reagent tubes 33 for batch blood drawing when drawing blood. Therefore, the automatic separation device is set on the left pipe 320, which can make it more convenient for the doctor to replace the reagent tube 33 during blood drawing.

[0038] In this embodiment, a scale 35 is engraved on the needle 30. According to the data displayed by the marking device 2, the doctor can judge the insertion distance of the needle based on the data. The setting of the scale 35 allows the doctor to observe the insertion distance of the needle 30 more clearly, thereby preventing the doctor from over-puncturing and improving the doctor's tolerance for acupuncture.

[0039] In this embodiment, a fixing adhesive 36 is fixedly provided on the outer side of the left pipe 320. After the doctor completes the acupuncture, the fixing adhesive 36 sticks to the patient's skin to prevent the left pipe 320 from moving.

[0040] In this embodiment, a circular handle 37 is fixedly provided on one side of the syringe, and the circular handle 37 allows the doctor to choose the pen-type or butterfly-wing puncture technique according to his or her own habits.

[0041] Specific implementation process: first, put the two ends of the arc buckle strip 10 on the back of the ear, make the arc connecting strip 11 buckle the doctor's head and make the micro camera 13 be located at the doctor's forehead, then start the infrared light source 12 and the micro camera 13 to display the arterial path on the skin, then place the marking body 20 on the arterial path, make the infrared rangefinder 23 irradiate on the skin, and the display 24 displays the data, then push the cross mark plate 22 downward to make the dye strip 25 press on the skin, and then use the pipe clamp 34 to clamp the right pipe 32 1, and then insert the outlet of the left pipeline 320 into the reagent tube 33, so that the movable plate 41 is attached to the fixed plate 40, and then compare the data displayed on the display instrument 24, observe the scale 35 on the needle 30 to control the distance of the needle 30 piercing into the skin, and draw arterial blood. When the current reagent tube 33 is full or the reagent tube 33 needs to be replaced, hold the two ends of the fixed plate 40 and push the separation button 42, so that the movable plate 41 is attached to the reagent tube 33 and exerts pressure on the reagent tube 33, and pull the fixed plate 40 to separate the left pipeline 320 from the reagent tube 33.

[0042] When it is necessary to draw arterial blood for arterial testing and arterial blood for venous testing from the patient at the same time, the tube plug 322 can be first pulled out to connect the right pipeline 321 to the reagent tube 33, and then the left pipeline 320 can be clamped with the tube clamp 34, and then the needle 30 can be inserted into the artery to draw arterial blood for arterial testing. After the arterial blood for arterial testing is drawn, the right pipeline 321 can be clamped with the tube clamp 34, and then the tube clamp 34 of the left pipeline 320 can be removed, and the left pipeline 320 can be connected to the reagent tube 33, and then arterial blood for venous testing can be drawn.

[0043] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
