Description

Technical Field

[0001] The utility model relates to the technical field of medical monitoring tools, in particular to a capillary refill time test monitor. Background Art

[0002] Capillary refill time monitoring measures the time required for capillaries to return to their original color after being compressed. Generally, it is normal for capillary refill time to not exceed 3 seconds.

[0003] At present, the way medical staff measure capillary refill time is: press the patient's fingertips with fingers or cotton swabs for a while and then remove the pressure. After the fingertips are no longer pressed, observe with the naked eye whether the pressed area has completely recovered its original color, and measure the time it takes to recover to its original color by counting in the mind or using timing tools such as stopwatches. However, it is impossible to accurately judge whether the tissue at the pressed area has completely recovered to its original color by the naked eye alone, and because the measurement time is very short, the accuracy of the timing will also be affected by manual timing operations, thereby reducing the accuracy of capillary refill time monitoring. In addition, most of the area that needs to be observed is covered by the medical staff's own fingers or cotton swabs and other tools, so that the medical staff cannot observe the color changes of the patient's fingertips in a timely and convenient manner, which affects the medical staff's ability to make correct judgments.

[0004] In view of the above problems, it is necessary to design a capillary refill time test monitor that displays the pressure data after pressing the fingertips. Utility Model Content

[0009] As an improvement to the above solution, the pressing block is made of a transparent material.

[0010] As an improvement of the above solution, the rubber splint is in a semi-arc shape.

[0011] As an improvement of the above solution, the number of guide rods is not less than two.

[0012] The beneficial effect of the utility model is as follows: the medical staff puts the patient's fingers on the pad, the telescopic end of the cylinder drives the pressing block to move downward, the pressing block contacts the patient's fingertips and drives them to move downward, and then drives the pad downward, and contacts the pressure sensor during the movement of the pad, so that the pressure sensor sends a signal, the signal is received by the display screen, and the received data is displayed on the display screen, after pressing for 10 seconds, the telescopic end of the cylinder drives the pressing block to move upward, the pressing block no longer presses on the patient's fingertips, so that the capillaries on the patient's fingertips return to their original color, and at the same time the camera monitors the time when the capillaries on the patient's fingertips return to their original color and transmits it to the display screen.

[0018] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0019] Example: Capillary refill time test monitor, such as Figure 1-Figure 4 As shown, it includes a bracket 1, a cylinder 2, a pressing block 3, a display screen 4, a camera 5, a pad 6, a first elastic member 7, a pressure sensor 8, a guide rod 9, a rubber splint 10, a second elastic member 11 and a protective pad 12. The bracket 1 is equipped with a cylinder 2, and the telescopic end of the cylinder 2 is connected with a pressing block 3, which can press the fingertips of the patient's fingers. The pressing block 3 is made of a transparent material, so that the camera 5 can monitor the refilling of the capillaries of the fingertips of the patient through the pressing block 3. The bracket 1 is rotatably connected with a display screen 4, which can display the transmitted data. The bracket 1 is rotatably connected with a camera 5, which can transmit the data of the capillaries recovering their original colors when the fingertips of the patient's fingers are no longer pressed to the display screen 4. The bracket 1 is slidably connected with a pad 6, which can The patient's finger is placed on the pad 6, and a first elastic member 7 is connected between the pad 6 and the bracket 1, and the first elastic member 7 is a tension spring. A pressure sensor 8 is installed on the bracket 1, which can send a signal when the pad 6 contacts the pressure sensor 8. A guide rod 9 is slidably connected to the bracket 1, which can play a guiding role. The number of guide rods 9 is not less than two, and a rubber splint 10 is connected to the opposite side of the two guide rods 9. The rubber splint 10 is semi-arc-shaped and made of rubber material, which is not easily scratched when the patient's finger is fixed. A second elastic member 11 is connected between the rubber splint 10 and the guide rod 9, and the second elastic member 11 is a compression spring. A protective pad 12 is connected to the outside of the display screen 4, and the protective pad 12 is attached to the four ends of the outside of the display screen 4 to facilitate the protection of the display screen 4.

[0020] When the device is needed, when the capillary refill time of the fingertips of the patient's fingers needs to be monitored, the medical staff places the device on the edge of the bed. After the device is placed, because the patient lies on the bed for a long time, and if the patient is in shock, he cannot put his fingers on the device by himself, and the medical staff needs to assist in putting the patient's fingers on the device, and then pull the camera 5 to rotate along the bracket 1. When the camera 5 rotates to a suitable angle, the camera 5 is no longer rotated, and the camera 5 is turned on again, so that the camera 5 is aligned with the contact position of the pad 6 and the pressure sensor 8 for monitoring, and then the display screen 4 and the pressure sensor 8 are turned on, and then the rubber splint 10 is pulled to drive the guide rod 9 to move outward, the second elastic member 11 is compressed, and then the patient's The finger is placed between the two rubber splints 10, and the patient's finger is moved under the pressing block 3 so that the finger pulp is aligned with the position of the pressing block 3, and the patient's finger is also in contact with the pad 6 and placed on it, and then the rubber splint 10 is released. Under the reset action of the second elastic member 11, the rubber splint 10 drives the guide rod 9 to move inward, and contacts and fixes the patient's finger during the movement of the rubber splint 10. After the patient's finger is fixed, the medical staff starts the cylinder 2, and the telescopic end of the cylinder 2 drives the pressing block 3 to move downward. The pressing block 3 moves to contact the finger pulp of the patient's finger and drives it to move downward. During the movement of the patient's finger, the pad 6 is driven to move downward along the bracket 1, and the first elastic member 7 is stretched. Because the camera 5 is connected to the display screen, 4 is electrically connected, so that the camera 5 can monitor in real time the time when the nail bed on the patient's finger is pressed and the time when the capillaries recover to the original color after being pressed, and the pressure sensor 8 is electrically connected to the display screen 4. When the pad 6 moves to contact with the pressure sensor 8, the pressure sensor 8 sends a signal, so that the display screen 4 receives the signal and displays the received pressure data on the display screen 4. After pressing for 10 seconds, the telescopic end of the cylinder 2 drives the pressing block 3 to move upward. After the pressing block 3 moves to a suitable height, the cylinder 2 is closed. At this time, after the fingertips of the patient's fingers are no longer pressed, the capillaries on the fingertips of the patient's fingers recover to their original color. At the same time, the camera 5 transmits the time when the capillaries on the fingertips of the patient's fingers recover to the original color to the display screen. On the display screen 4, the display screen 4 displays its data. When the capillary refill time monitoring of the patient's finger pulp is completed, the medical staff pulls the rubber splint 10 to drive the guide rod 9 to move outward, the second elastic member 11 is compressed, and then the patient's finger is removed from the pad 6, and then the rubber splint 10 is released. Under the reset action of the second elastic member 11, the rubber splint 10 drives the guide rod 9 to move inward to return to its original position. In the process of the patient's finger being removed from the pad 6, under the reset action of the first elastic member 7, the pad 6 moves upward along the bracket 1 to return to its original position. While the pad 6 moves, the pad 6 is out of contact with the pressure sensor 8. When the capillary refill time test monitoring operation is completed, the display screen 4, the camera 5 and the pressure sensor 8 are turned off.Medical staff can judge the patient's condition based on the monitoring data.
