Description

Technical Field

[0001] This utility model belongs to the technical field of dynamic blood pressure monitoring devices, specifically relating to a fixed protective sleeve for dynamic blood pressure monitoring devices. Background Technology

[0002] Ambulatory blood pressure monitoring (ABPM) is a medical device used to monitor blood pressure dynamically and continuously. It can accurately record blood pressure values ​​and help doctors diagnose hypertension. It allows for online monitoring of patients' blood pressure. ABPM involves continuously measuring blood pressure over a certain period (usually one to two days) (the time interval is set according to the actual situation). Based on the measurement results, it can determine the blood pressure readings at different times and under different lifestyle conditions, and provide a blood pressure diagnosis accordingly. A fixed protective sleeve is required during the testing process.

[0003] Existing fixed sheaths are used by wrapping the sheath around the arm for subsequent testing. However, since the sheath needs to be worn on the patient's arm for a long time during the testing process, the wearing area is prone to sweating, causing discomfort to the wearer, and the sheath needs to be removed for treatment. Secondly, relying solely on a single adhesive structure, the sheath is prone to shifting during inflation and deflation, thus deviating from its intended position and reducing the accuracy of the test data. Therefore, we provide a fixed sheath for dynamic blood pressure monitoring devices. Utility Model Content

[0004] The purpose of this invention is to provide a fixed protective sleeve for a dynamic blood pressure monitor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed protective sleeve for a dynamic blood pressure monitor, comprising a sleeve body, an air bladder at the bottom of the inner side of the sleeve body, a connecting tube connected to the input end of the air bladder, a threaded sleeve connected to the surface of the connecting tube, a flexible tube connected to one end of the threaded sleeve, and one end of the flexible tube connected to the output end of an external blood pressure monitor, ventilation holes on both sides of the sleeve body, an elastic band at the bottom right side of the sleeve body, a Velcro closure on the inner side of the elastic band, and a Velcro closure on the right side of the top of the sleeve body.

[0006] By adopting the above solution, since the Velcro liner has fine and soft fibers and the Velcro tab has harder hook-shaped fibers, when these two parts come into contact with each other, the hooks on the Velcro tab will hook onto the fibers on the Velcro liner, thus forming a tight connection. At the same time, since there are three elastic bands, multiple fixation is formed to prevent the force generated during the inflation and deflation of the airbag from causing the sheath body to shift from the predetermined position, thereby improving the stability of the sheath body when worn.

[0007] As a preferred embodiment of a fixed sheath for a dynamic blood pressure monitor, the inner side of the threaded sleeve is provided with an internal thread, and the surface of the connecting tube is provided with an external thread, and the external thread is compatible with the internal thread.

[0008] By adopting the above solution and utilizing the compatibility of external and internal threads, the threaded sleeve and connecting pipe can be installed quickly, greatly improving the installation efficiency.

[0009] In a preferred embodiment of a fixed sheath for a dynamic blood pressure monitor, the number of elastic bands is three, and the elastic bands are made of polytetrafluoroethylene elastic bands.

[0010] By adopting the above solution, the elastic band is made of polytetrafluoroethylene, which has good flexibility and compression resilience, making it less prone to damage and greatly extending the service life of the elastic band.

[0011] As a preferred embodiment of a fixed sheath for a dynamic blood pressure monitor, the Velcro closure has fine, soft fibers, and the Velcro closure has stiffer, hook-shaped fibers.

[0012] Using the above method, when the fine and soft fibers and the hooked fibers come into contact with each other, the hooked fibers will hook onto the fine fibers, forming a tight connection. When it is necessary to separate them, they can be separated with just a gentle pull, making it extremely convenient to use.

[0013] As a preferred embodiment of a fixed sheath for a dynamic blood pressure monitor, the output end of the airbag is connected to an exhaust pipe, and a sealing cap is threaded onto the exhaust pipe.

[0014] By adopting the above solution and setting a sealing cap, gas is prevented from escaping from the exhaust pipe during the inflation process of the airbag, thus improving the sealing performance of the exhaust pipe.

[0015] As a preferred embodiment of a fixed protective sleeve for a dynamic blood pressure monitor, the bottom of the airbag is bonded with an anti-slip pad, and the anti-slip pad is made of rubber.

[0016] By adopting the above solution, the friction between the airbag and the patient's arm is increased through the addition of anti-slip pads, making the sheath less prone to slipping and further improving the stability of the sheath when worn.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model features a Velcro closure with fine, soft fibers and a Velcro closure with stiffer, hook-shaped fibers. When these two parts come into contact, the hooks on the Velcro closure hook onto the fibers on the Velcro closure, thus forming a tight connection. At the same time, the presence of three elastic bands provides multiple layers of fixation, preventing the airbag from shifting from its intended position due to the force generated during inflation and deflation, thereby improving the stability of the airbag when worn.

[0019] 2. Because the protective sleeve body has ventilation holes on both sides, the gas inside the protective sleeve body can be smoothly exchanged with the outside air, preventing the sweat from easily growing at the wearing position during long-term wear and causing discomfort to the patient.

[0024] Please see Figure 1-3A fixed protective sleeve for a dynamic blood pressure monitor includes a sleeve body 1. An air bladder 2 is located at the bottom inner side of the sleeve body 1. The output end of the air bladder 2 is connected to an exhaust pipe, and a sealing cap is threaded onto the exhaust pipe. The sealing cap prevents gas from escaping from the exhaust pipe during inflation, improving the sealing performance of the exhaust pipe. A connecting pipe 3 is connected to the input end of the air bladder 2. A threaded sleeve 4 is connected to the surface of the connecting pipe 3. One end of the threaded sleeve 4 is connected to a flexible tube 5, and one end of the flexible tube 5 is connected to the output end of an external blood pressure monitor. Ventilation holes 6 are provided on both sides of the sleeve body 1. An elastic band 8 is located at the bottom right side of the sleeve body 1, and a Velcro closure 9 is located on the inner side of the elastic band 8. The top right side of the sleeve body 1... The airbag 2 is equipped with Velcro 7, and an anti-slip pad is attached to the bottom of the airbag 2. The anti-slip pad is made of rubber. The anti-slip pad increases the friction between the airbag 2 and the patient's arm, making the sheath body 1 less prone to slipping and further improving the stability of the sheath body 1 when worn. Because the Velcro 9 has fine and soft fibers, while the Velcro 7 has harder hook-shaped fibers, when these two parts come into contact with each other, the hooks on the Velcro 7 will hook onto the fibers on the Velcro 9, thus forming a tight connection. At the same time, because there are three elastic bands 8, multiple fixation is formed to prevent the force generated during the inflation and deflation of the airbag 2 from causing the sheath body 1 to deviate from the predetermined position, thus improving the stability of the sheath body 1 when worn.

[0025] See Figure 3 As shown, the inner side of the threaded sleeve 4 is provided with an internal thread 10, and the surface of the connecting pipe 3 is provided with an external thread. The external thread and the internal thread 10 are compatible. Utilizing the compatibility of the external and internal threads 10, the threaded sleeve 4 and the connecting pipe 3 can be quickly installed, greatly improving installation efficiency. Figure 1 As shown, there are three elastic bands 8. The elastic bands 8 are made of polytetrafluoroethylene (PTFE). Because the elastic bands 8 are made of PTFE, they have good flexibility and compression resilience, are not easily damaged, and their service life is greatly extended. Figure 2 As shown, the Velcro 9 has fine, soft fibers, while the Velcro 7 has stiffer, hook-shaped fibers. When the fine, soft fibers and the hook-shaped fibers come into contact with each other, the hook-shaped fibers hook onto the fine fibers, forming a tight connection. When it is necessary to remove the connection, it can be separated with a gentle pull, making it extremely convenient to use.

[0026] In use, first wrap the sheath body 1 around the patient's arm. Then pull the elastic band 8, moving the Velcro 9 on the elastic band 8 towards the Velcro 7 until the Velcro 9 and Velcro 7 are in contact and the movement stops. Because the Velcro 9 has fine, soft fibers, while the Velcro 7 has stiffer, hook-like fibers, when these two parts come into contact, the hooks on the Velcro 7 will hook onto the fibers on the Velcro 9, thus forming a tight connection. Simultaneously, because there are three elastic bands 8, multiple layers of fixation are formed to prevent the force generated during the inflation and deflation of the airbag 2. This causes the sheath body 1 to shift to a predetermined position, improving the stability of the sheath body 1 when worn. Furthermore, since ventilation holes 6 are provided on both sides of the sheath body 1, the gas inside the sheath body 1 can be smoothly exchanged with the outside air, preventing sweat from easily accumulating at the wearing position during long-term wear and causing discomfort to the patient. Finally, an external blood pressure monitor is used to inflate the airbag 2 with the help of the tubing 5, causing the airbag 2 to expand. During the expansion process, the airbag 2 will compress the wearing position and block the blood flow at the wearing position, so that the blood pressure value during this period can be measured.
