[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] refer to Figure 1-Figure 5 A hysteroscopic surgery perfusion tube bubble removal device comprises a bubble filter housing 1, a liquid discharge housing 2 is arranged on the right side of the bubble filter housing 1, the bubble filter housing 1 and the liquid discharge housing 2 are both made of medical grade transparent plastic material, and the bubble filter housing 1 and the liquid discharge housing 2 are of the same size; By setting the bubble filter housing 1 and the liquid discharge housing 2 to be of the same size, it is convenient to subsequently connect the bubble filter housing 1 and the liquid discharge housing 2 together to form a whole, so as to facilitate debubbling of liquids such as physiological saline or mannitol flowing in the perfusion tube; The medical grade transparent plastic can be made of a combination of polymers such as polycarbonate (PC) and polymethyl methacrylate (PMMA), so that it is convenient for personnel to observe the internal conditions and liquid flow of the bubble filter housing 1 and the liquid discharge housing 2.

[0019] refer to Figure 1 , Figure 2 and Figure 3 A liquid discharge hose 3 is fixedly installed at one end of the liquid discharge housing 2, a perfusion pipe 4 is fixedly installed at the front end of the bubble filter housing 1, a pressurized perfusion mechanism 5 is arranged at one end of the perfusion pipe 4 away from the bubble filter housing 1, and a filter assembly 6 is arranged inside the bubble filter housing 1; One end of the drainage hose 3 is connected to the perfusion gun, so that it is convenient to inject the liquid after the bubbles are removed into the patient's body. Through the set booster perfusion mechanism 5, it is convenient to pressurize the liquid to be injected into the patient's body. Through the set filter component 6, it is convenient to filter the air in the liquid so that no bubbles are generated when the liquid is discharged.

[0020] refer to Figure 1 The pressurized perfusion mechanism 5 includes a medical pressurizer 18, a liquid storage bag 19 and a medical connecting tube 20. The medical pressurizer 18 is provided at one end of the perfusion tube 4, and the end of the perfusion tube 4 away from the bubble filter housing 1 is connected to the liquid outlet end of the medical pressurizer 18; The medical booster 18 is provided to facilitate the subsequent pressurization of the liquid and its transport to the interior of the perfusion tube 4 , so that the liquid can enter the interior of the drainage hose 3 at a certain pressure.

[0021] refer to Figure 1 , Figure 2 A liquid storage bag 19 is provided on one side of the medical booster 18, a medical connecting tube 20 is fixedly installed on the bottom surface of the liquid storage bag 19, and one end of the medical connecting tube 20 away from the liquid storage bag 19 is connected to the liquid inlet end of the medical booster 18; The liquid storage bag 19 is provided to facilitate storage of the perfusion liquid, so that the liquid inside the liquid storage bag 19 can enter the medical booster 18 through the medical connecting tube 20 and be discharged after being pressurized.

[0022] refer to Figure 1 , Figure 2 and Figure 3 , a partition plate 21 is fixedly installed inside the liquid discharge housing 2; When the pressurized liquid contacts the partition 21 after filtering out bubbles, the partition 21 will block the liquid after debubbling. The mitigation effect is to help the liquid to debubble more effectively, so that the tiny bubbles in the liquid can be eliminated or reduced. When the liquid gradually accumulates on one side of the partition 21, if the liquid level exceeds a certain level or continues to accumulate to a certain extent, the liquid will pass through the barrier of the partition 21 and then flow out through the drainage hose 3. In this process, the partition 21 plays a key buffering and regulating role, ensuring that the liquid can flow out smoothly and continuously, and maximizing the quality of the liquid and the debubbling effect.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The filter assembly 6 includes a vertical plate 7, a filter membrane layer 8, a waterproof breathable membrane 9 and an exhaust hole 10. The vertical plate 7 is fixedly installed inside the bubble filter housing 1, and the filter membrane layer 8 is fixedly installed on the bottom surface of the vertical plate 7; The vertical plate 7 is provided to facilitate installation of the filter membrane layer 8, and the filter membrane layer 8 can block the air in the liquid.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The filter membrane layer 8 includes a PVDF filter membrane 15 and a PES filter membrane 16. The PVDF filter membrane 15 is fixedly installed on the bottom surface of the vertical plate 7. The bottom surface of the filter membrane layer 8 is located in front of the PVDF filter membrane 15 and is provided with a PES filter membrane 16; The PVDF filter membrane 15 and the PES filter membrane 16 are hydrophilic but repellent to gas molecules, and play a key role in liquid filtration. They can effectively block the air in the liquid and filter it. The two filter membranes achieve the filtering effect of the air in the liquid through their unique material and structural characteristics. When the liquid passes through the filter membrane, its surface tension effectively blocks the bubbles, while the liquid passes through smoothly. In this way, the filter membrane helps to improve the purity and fluidity of the liquid, and can effectively capture and remove tiny bubbles in the liquid to ensure the quality of the liquid. As a result, the filtration efficiency of the liquid is improved and its stability is ensured.

[0025] refer to Figure 2 , Figure 3 and Figure 5 A waterproof breathable membrane 9 is fixedly installed on one side of the vertical plate 7, a sterile mesh cloth 17 is fixedly installed on one side of the vertical plate 7 below the waterproof breathable membrane 9, and three exhaust holes 10 are opened on the left side of the bubble filter housing 1; By setting a waterproof and breathable membrane 9, liquid can be blocked while allowing gas to pass through. This, when used in conjunction with the three exhaust holes 10, can effectively discharge the gas inside the bubble filter housing 1 and reduce the doping of air in the liquid. The waterproof and breathable membrane 9 is a special membrane that is both waterproof and breathable. When liquid flows through the waterproof and breathable membrane 9, water molecules will be blocked outside, while gas molecules can pass through the filter membrane. The three exhaust holes 10 are located on the side of the bubble filter housing 1. After the gas molecules pass through the filter membrane, they will be discharged from the outside of the housing through the exhaust holes 10. Through the cooperation of the waterproof and breathable membrane 9 and the exhaust holes 10, bubbles in the liquid can be effectively removed. The liquid flows in from the bottom of the housing, and after being filtered by the waterproof and breathable membrane 9, the bubbles are discharged, thereby obtaining a pure liquid without bubbles. This design can ensure that there are no bubbles in the liquid, and ensure the smooth progress of subsequent operations. The waterproof and breathable membrane 9 can be made of polytetrafluoroethylene PTFE material, which is a highly hydrophobic and breathable material with excellent chemical resistance and heat resistance. The sterile mesh cloth 17 can improve the impact resistance of the waterproof breathable membrane 9, so that the waterproof breathable membrane 9 will not be easily damaged.

[0026] refer to Figure 1 , Figure 2 and Figure 3 A connection protrusion 11 is fixedly installed on one side of the bubble filter housing 1 close to the liquid discharge housing 2, and a connection groove 12 corresponding to the connection protrusion 11 is opened on one side of the liquid discharge housing 2 close to the bubble filter housing 1, and the connection protrusion 11 is inserted into the inside of the connection groove 12, and a sealing gasket 22 is fixedly installed inside the connection groove 12; The connection protrusion 11 is inserted into the connection groove 12, so that the bubble filter housing 1 and the liquid discharge housing 2 are connected to form a whole. The sealing gasket 22 is provided to improve the sealing of the connection between the bubble filter housing 1 and the liquid discharge housing 2.

[0027] refer to Figure 2 , Figure 3 and Figure 4 The top and bottom surfaces of the liquid discharge housing 2 are respectively fixedly mounted with a block 13, and the top and bottom surfaces of the bubble filter housing 1 are fixedly mounted with a block 2 14 corresponding to the block 13, and the block 13 is clamped with the block 2 14; When the bubble filter housing 1 and the liquid discharge housing 2 are connected together, the sealing gasket 22 is compressed to achieve a sealing effect, and the clamping block 13 and the clamping block 2 14 are clamped together, so that it is convenient to fix the connected bubble filter housing 1 and the liquid discharge housing 2.

[0028] The implementation principle of the embodiment of the hysteroscopic surgery perfusion tube bubble removal device of the present invention is as follows: the operator first connects and fixes the bubble filter housing 1 and the liquid discharge housing 2 to form an integral structure, then connects the liquid discharge hose 3 to the external perfusion gun, and connects the perfusion tube 4 to the pressurized perfusion mechanism 5. When the medical supercharger 18 pressurizes the liquid such as physiological saline or mannitol in the liquid storage bag 19, these liquids enter the bubble filter housing 1 through the perfusion tube 4. Due to the high liquid pressure, the air in the housing will be discharged through the exhaust hole 10; When the liquid enters the interior of the bubble filter housing 1, the liquid can enter the interior of the liquid discharge housing 2 through the filtration of the filter membrane layer 8, the PVDF filter membrane 15 and the PES filter membrane 16, and the air in the liquid will move upward through the waterproof breathable membrane 9 under the action of pressure, so that the air in the liquid can be discharged through the three exhaust holes 10, so that the injected liquid will not continuously have bubbles and intermittent situations when it is sprayed out by the injection gun, thereby ensuring the purity of the liquid; The waterproof and breathable membrane 9 of the device plays a key role. It can block the entry of liquid while allowing air to pass through. Under the action of pressure, the air in the liquid will move upward through the waterproof and breathable membrane 9 and be effectively discharged through the three exhaust holes 10. This design ensures that there will be no continuous bubbles and intermittent situations when pouring liquid, reduces the exhaust time of the filling tube 4, and improves efficiency. In addition, the impact resistance of the waterproof and breathable membrane 9 is enhanced by the provision of the sterile mesh cloth 17, making it more durable. The split design of the bubble filter shell 1 and the liquid discharge shell 2 makes subsequent maintenance more convenient. Only the bubble filter shell 1 needs to be replaced, which reduces the cost. In general, the device is reasonably designed and simple to operate, and can effectively ensure the purity of the liquid and the stability during discharge.
