Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a blood vessel perfusion plug device made of silicone material with a pressure measuring function. Background Art

[0002] In the medical field, vascular perfusion is a commonly used treatment method, playing an important role in intensive care, surgical procedures, and the treatment of specific diseases. During vascular perfusion, precise control of perfusion pressure is crucial. Excessive perfusion pressure may lead to complications such as vascular wall damage and bleeding, while too low perfusion pressure may not meet treatment needs. Therefore, the development of a vascular perfusion tool that can monitor and adjust perfusion pressure in real time has become an urgent need in the medical field.

[0003] As a material with good biocompatibility and high flexibility, silicone has been widely used in the medical field. In recent years, with the continuous advancement of medical technology, the application of silicone in vascular perfusion tools has gradually increased. However, most of the vascular perfusion tools on the market currently have problems such as complex operation and inability to monitor perfusion pressure in real time, which limits their application in clinical practice. Summary of the Invention

[0004] In response to the above-mentioned problems, the utility model aims to provide a vascular perfusion plug device made of silicone material with a pressure measuring function. By designing a pressure regulating component, the perfusion pressure in the infusion tube is pre-set, and the pressure on the pressure test valve core is monitored through the display screen during vascular perfusion, thereby monitoring the perfusion pressure in real time. It has the advantages of simple structure, easy use, good safety and strong real-time performance.

[0005] The main idea of the technical solution adopted by the utility model is to design a pressure regulating component, and by turning the pressure regulating button, the pressure test valve core moves laterally along the thread of the pressure test valve core, so that the pressure test valve core moves laterally along the slide groove, and squeezes the squeeze disk and the compression spring, and pre-sets the perfusion pressure in the infusion tube. During blood vessel perfusion, the pressure on the pressure test valve core is monitored through the display screen to monitor the perfusion pressure in real time.

[0006] In order to achieve the above purpose, the technical solutions adopted by this utility model are as follows:

[0007] A vascular perfusion plug device made of silicone material with a pressure measuring function includes a first infusion tube and a second infusion tube for vascular perfusion, wherein a pressure regulating component for presetting and monitoring the perfusion pressure is provided between the first infusion tube and the second infusion tube.

[0008] The pressure regulating assembly includes a shell, the liquid inlet at one end of the shell is connected to the liquid outlet of the first infusion tube, the liquid outlet on the side wall of the shell is connected to the liquid inlet of the second infusion tube, and a pressure regulating button is provided at the end of the shell away from the first infusion tube. One end of the pressure regulating button penetrates into the shell and is rotatably connected to the pressure test valve core slidably installed inside the shell.

[0009] Based on the above technical solution, further, an internal thread is provided in the middle of the pressure test valve core, and an external thread is provided at one end of the pressure regulating button that penetrates into the shell, and the internal thread in the middle of the pressure test valve core cooperates with the external thread on the pressure regulating button.

[0010] Based on the above technical solution, further, the upper and lower ends of the shell are provided with sliding grooves that enable the pressure test valve core to slide horizontally, and the upper and lower parts of the pressure test valve core are provided with sliders that cooperate with the sliding grooves.

[0011] Based on the above technical solution, further, an extrusion disc is slidably provided inside the shell and on a side away from the pressure test valve core, and a compression spring is provided between the extrusion disc and the pressure test valve core.

[0012] Based on the above technical solution, further, a display screen for observing the pressure applied to the pressure test valve core is provided on the outside of the housing, and a signal input end of the display screen is connected to a signal output end of the pressure test valve core.

[0013] A limiting ring is provided on the pressure test valve core and inside the compression spring. The diameter of the limiting ring matches the diameter of one end of the extrusion disk located inside the compression spring.

[0014] The liquid inlet of the first infusion tube is connected to the perfusion bag through a thread, and a needle for blood vessel perfusion is installed at the liquid outlet of the second infusion tube through a thread.

[0015] The beneficial effects of the utility model are:

[0016] 1. By designing a pressure regulating component, before vascular perfusion, the pressure regulating button is used to rotate and drive the pressure test valve core to move horizontally, thereby pre-setting the perfusion pressure in the shell and the infusion tube. When vascular perfusion begins, the liquid in the infusion tube squeezes the pressure test valve core and thus squeezes the compression spring. The pressure on the pressure test valve core is observed on the display screen to monitor the perfusion pressure. It has the advantages of ease of use and strong real-time performance.

[0017] 2. By designing a pressure regulating component, the perfusion pressure is monitored in real time and adjusted through the pressure regulating button to prevent damage to the blood vessel wall due to excessive perfusion pressure, or failure to perform normal perfusion due to too low perfusion pressure. It has good reliability and high safety.

[0018] 3. The overall structure of the utility model is simple and easy to replace and install. At the same time, since the silicone material has good biocompatibility and flexibility, the utility model can be applied to blood vessels of different sizes and types, and the second infusion tube can be installed with different needles through threads, which improves the scope of application of the utility model.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] The inventors have found that during the vascular perfusion process, precise control of the perfusion pressure is crucial. Excessively high perfusion pressure may lead to complications such as vascular wall damage and bleeding, while too low perfusion pressure may not meet the treatment needs. Most of the vascular perfusion tools currently on the market have problems such as complex operation and inability to monitor the perfusion pressure in real time, which limits their clinical application. Silicone, as a material with good biocompatibility and high flexibility, has been widely used in the medical field. In recent years, with the continuous advancement of medical technology, the application of silicone in vascular perfusion tools has gradually increased.

[0030] Based on the above findings, the present application proposes a vascular perfusion plug device made of silicone material with a pressure measuring function. By designing a pressure regulating component, when performing vascular perfusion, by turning the pressure regulating button, the pressure test valve core moves laterally along the thread of the pressure test valve core, and drives the pressure test valve core to move laterally, thereby pushing the extrusion disk and squeezing the compression spring, pre-setting the perfusion pressure in the infusion tube, and pushing the pressure test valve core through the medicine during vascular perfusion, thereby squeezing the compression spring, and observing the pressure data of the pressure test valve core through the display screen, thereby monitoring the perfusion pressure in real time.

[0031] See Figures 1-6 The present application discloses a vascular perfusion plug device made of silicone material with a pressure measuring function, including a first infusion tube 1 and a second infusion tube 2 for vascular perfusion. Specifically, the first infusion tube 1 and the second infusion tube 2 are made of silicone material as a whole. Since silicone material has good biocompatibility and high flexibility, it can improve the durability and applicability of the device.

[0032] A pressure regulating assembly 3 for presetting and monitoring the perfusion pressure is provided between the first infusion tube 1 and the second infusion tube 2. Figure 7 The pressure regulating assembly 3 includes a housing 301. In some embodiments, the housing 301 can be made of a corrosion-resistant lightweight metal or lightweight plastic. As shown in the accompanying drawings, the overall shape of the housing 301 is a hollow cylinder. In some embodiments, the overall shape of the housing 301 can also be a rectangular parallelepiped. The liquid inlet at one end of the housing 301 is connected to the liquid outlet of the first infusion tube 1, and the liquid outlet on the side wall of the housing 301 is connected to the liquid inlet of the second infusion tube 2. Specifically, the first infusion tube 1 and the second infusion tube 2 can be installed by providing threads on the liquid inlet and the side wall of the housing 301 and using matching threaded connectors.

[0033] A pressure regulating button 302 is provided at the end of the shell 301 away from the first infusion tube 1. One end of the pressure regulating button 302 penetrates into the shell 301 and is rotatably connected to a pressure test valve core 303 slidably installed inside the shell 301. Specifically, the overall shape of the pressure test valve core 303 is a cylinder, and an internal thread is provided in the middle of one end of the pressure test valve core 303. An external thread is provided at the end of the pressure regulating button 302 that penetrates into the shell 301. The internal thread in the middle of the pressure test valve core 303 cooperates with the external thread on the pressure regulating button 302. The rotation of the pressure regulating button 302 is converted into a lateral sliding of the pressure test valve core 303 in the shell 301 through the thread, so that the perfusion pressure inside the shell 301 can be accurately adjusted.

[0034] The upper and lower ends of the shell 301 are provided with sliding grooves 306 that enable the pressure test valve core 303 to slide horizontally, and the upper and lower parts of the pressure test valve core 303 are provided with sliders 307 that cooperate with the sliding grooves 306. When the pressure adjustment button 302 is rotated, the pressure test valve core 303 can slide horizontally along the inside of the shell 301 through the interaction of the threads, and the sliding grooves 306 and the sliders 307 can ensure the smooth sliding of the pressure test valve core 303 while preventing the pressure test valve core 303 from deflecting in the sliding direction during sliding; in some embodiments, the number of sliding grooves 306 and sliders 307 can be reduced or increased synchronously, but the number still needs to be kept corresponding, and the cross-sectional shapes of the sliding grooves 306 and the sliders 307 are matched.

[0035] A squeeze disc 304 is slidably provided inside the housing 301 and on a side away from the pressure test valve core 303. The squeeze disc 304 can be pushed by the pressure adjustment button 302 and slide laterally along the housing 301. A compression spring 305 is provided between the squeeze disc 304 and the pressure test valve core 303. When the pressure adjustment button 302 is turned to drive the pressure test valve core 303 to slide, or when the pressure test valve core 303 slides under the action of the perfusate in the first infusion tube 1 and the second infusion tube 2, the compression spring 305 can be squeezed.

[0036] A display screen 309 is provided on the outside of the housing 301 for observing the pressure applied to the pressure test valve core 303. The signal input end of the display screen 309 is connected to the signal output end of the pressure test valve core 303. It should be noted that the pressure test valve core 303 proposed in the present invention is a common spring pressure sensor on the market as the valve core, such as the "GEFRAN KX pressure sensor". The display screen 309 is a common display screen device on the market with a data display function, which will not be described in detail herein.

[0037] Before performing blood vessel perfusion, the pressure adjustment button 302 is first turned to drive the pressure test valve core 303 to move horizontally to preset the perfusion pressure. When the medical liquid flows into the shell 301 through the first infusion tube 1, the medical liquid pushes the pressure test valve core 303 to the side close to the pressure adjustment button 302, thereby flowing into the second infusion tube 2. The perfusion medical liquid pressure data of the pressure test valve core 303 is read through the display screen 309. When it is found that the perfusion pressure is too high or too low, the perfusion pressure is adjusted by turning the pressure adjustment button 302 to avoid damage to the blood vessel wall due to excessive perfusion pressure, or failure to perform normal perfusion due to excessive perfusion pressure.

[0038] A limit ring 308 is provided on the pressure test valve core 303 and inside the compression spring 305. The diameter of the limit ring 308 matches the diameter of one end of the extrusion disk 304 located inside the compression spring 305. By providing the limit ring 308, the compression spring 305 can be prevented from being over-extruded when adjusting the perfusion pressure, thereby affecting the accuracy of perfusion pressure monitoring.

[0039] The liquid inlet of the first infusion tube 1 is connected to the perfusion bag through a thread, Figure 8 The liquid outlet of the second infusion tube 2 is threadedly mounted with a needle 4 for vascular perfusion. By threading the perfusion bag or the needle 4, the device can be quickly installed. At the same time, the second infusion tube 2 can be threadedly mounted with needles 4 of different sizes to adjust to different sizes and types of blood vessels. It has a wide range of applications and is easy to replace the needle 4.

[0040] Install the first infusion tube 1 and the second infusion tube 2 to the end of the housing 301 away from the pressure adjustment button 302 and the side wall of the housing 301, and connect them to the perfusion bag and the needle 4, respectively.

[0041] Before starting vascular perfusion, the pressure adjustment button 302 can be turned to slide the pressure test valve core 303 laterally and squeeze the compression spring 305 to preset the perfusion pressure. The preset perfusion pressure can be observed on the display screen 309.

[0042] When blood vessel perfusion begins, the liquid medicine in the perfusion bag flows into the housing 301 through the first infusion tube 1, squeezes the pressure test valve core 303, then flows into the second infusion tube 2, and is perfused into the blood vessel through the needle 4. At this time, the pressure test valve core 303 squeezes the compression spring 305 under the action of the liquid medicine. The pressure on the pressure test valve core 303 is observed through the display screen 309, thereby monitoring the perfusion pressure in real time.

[0043] Observe the changes in pressure data and turn the pressure adjustment button 302 according to the size of the perfusion pressure to adjust the perfusion pressure to ensure that the blood vessel perfusion can proceed smoothly.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
