Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a hysteroscopic irrigation and pressurization device. Background Technology

[0002] Hysteroscopy is a minimally invasive gynecological diagnostic and treatment technique that allows direct visualization of intrauterine lesions. It enables rapid and accurate diagnosis of most intrauterine diseases, making it the preferred examination method for gynecological bleeding disorders and intrauterine lesions. The hysteroscopic system includes a hysteroscope, an energy system, a light source system, an irrigation system, and an imaging system. In the irrigation system, the fluid in the bag is connected to an infusion tube, which is then connected to the hysteroscope body via a medical pressure device.

[0045] Please see Figure 1-3 This embodiment provides a hysteroscopic irrigation and pressurization device, which includes: a pressurizer 1, which includes a pressurizing component 11, a fixing component 12, a mounting bracket 13, and a processor; the pressurizing component 11 and the fixing component 12 are disposed adjacent to each other on the front of the pressurizer 1, and the pressurizing component 11 is connected to a drive motor located inside the pressurizer 1; the mounting bracket 13 is disposed on the side of the pressurizer 1; the processor includes a signal receiving module and a control module, and both the drive motor and the signal receiving module are communicatively connected to the control module; an air detector 2, and an air... The gas detector 2 includes a detection part 21 and a clamping part 22. One side of the detection part 21 is movably connected to one side of the clamping part 22. The detection part 21 has a first half-hole 211 through it, and the clamping part 22 has a second half-hole 221 through it. The first half-hole 211 and the second half-hole 221 together form a detection channel. The size of the detection channel is adapted to the size of the mounting bracket 13. The detection part 21 is equipped with a detection module and a signal transmission module. The detection module is communicatively connected to the signal transmission module, and the signal transmission module is communicatively connected to the signal receiving module.

[0046] Specifically, this utility model provides a hysteroscopic irrigation pressurization device, including a pressurizer 1 and an air detector 2. The pressurizer 1 includes a pressurization component 11, a fixing component 12, a mounting bracket 13, and a processor. The pressurization component 11 and the fixing component 12 are arranged adjacent to each other on the front of the pressurizer 1. The pressurization component 11 is connected to a drive motor located inside the pressurizer 1. The hysteroscopic irrigation system includes an infusion bag and an infusion tube. The infusion bag is connected to the front end of the infusion tube, the middle part of the infusion tube is connected to the connecting tube in the pressurizer 1, and the rear end of the infusion tube... The segment is connected to the hysteroscope, and the connecting tube is wound around the pressurizing component 11. The pressurizing component 11 is used to accelerate the push of the fluid passing through the connecting tube, thereby increasing the infusion rate. The fixing component 12 is used to stabilize and fix the connectors at both ends of the connecting tube, preventing them from moving or falling off during pressurization. The mounting bracket 13 is set on the side of the pressurizer 1 and can be used to fix the air detector 2. The processor includes a signal receiving module and a control module. The drive motor and the signal receiving module are both communicatively connected to the control module to realize the function of receiving the signal from the air detector 2 and pausing the pressurizing component 11. The air detector 2 includes a detection part 21 and a clamping part 22. The detection part 21 has a first half-hole 211 through it, and the clamping part 22 has a second half-hole 221 through it. The first half-hole 211 and the second half-hole 221 together form a detection channel. In use, the air detector 2 can be clamped onto the infusion tube. The size of the detection channel is adapted to the size of the infusion tube to detect the inside of the infusion tube. At the same time, the size of the detection channel is adapted to the size of the mounting bracket 13. When not in use, it can be hung on the mounting rack 13 for storage; the detection unit 21 is equipped with a detection module and a signal transmission module. The detection module is used to detect whether the infusion tube is empty. The signal transmission module is used to transmit the detection result of the detection module to the signal receiving module of the pressurizer 1, and then to the control module to realize the start / stop operation function of the drive motor, thereby stopping the pressurizing component 11 from continuing to pressurize, so as to avoid the patient's uterine air embolism caused by continuing to pressurize when the infusion bag is empty and the infusion tube is empty.

[0047] Specifically, during the procedure, the operator should first clamp the air detector 2 to the front of the infusion tubing, near the connection between the tubing and the infusion bag, to immediately detect the fluid in the tubing. The detection module should promptly detect when the infusion bag has finished delivering fluid and the tubing is empty. The signal transmission module should then transmit this empty tubing signal to the signal receiving module, which will then stop the drive motor via the control module. This prevents the pressurizing assembly 11 from continuing to pressurize the connecting tubing when both the infusion bag and tubing are empty, thus preventing air from being delivered to the infusion bag. The medication is delivered into the uterus, thus preventing air from entering the patient's body and causing serious patient safety accidents, improving the safety of use, and preventing medical accidents caused by air embolism in the patient's uterus. The medication flows through the infusion tube to the connecting tube, and the connectors at both ends of the connecting tube are fixed to the fixing component 12. The tubing of the connecting tube is wrapped around the pressurizing component 11 to push the medication, accelerate the delivery pressure of the medication, and push it to the downstream section of the infusion tube so that it can be delivered into the uterine cavity through the hysteroscope. The medication is delivered into the uterus through the hysteroscope, which can expand the uterine cavity and facilitate the doctor to observe the condition of the uterine cavity during surgery.

[0048] In some possible implementations, two connecting rods 23 are provided at the movable connection between the detection part 21 and the clamping part 22, and the two connecting rods 23 are arranged vertically at intervals; one end of each connecting rod 23 is fixedly connected to one side of the detection part 21, and two telescopic holes are provided on one side of the clamping part 22. A spring is provided in each of the two telescopic holes, and the other end of each connecting rod 23 extends into the corresponding telescopic hole and is fixedly connected to the spring.

[0049] Specifically, such as Figure 3-4 As shown, two connecting rods 23 are provided at the movable connection between the detection part 21 and the clamping part 22. One end of the two connecting rods 23 is fixedly connected to one side of the detection part 21, and the other end of the two connecting rods 23 extends into the corresponding telescopic hole and is fixedly connected to the spring. This makes the detection part 21 and the clamping part 22 combine into a clamp structure, which is convenient for clamping and fixing on the infusion tube and can provide a stable environment for detecting the infusion status in the infusion tube.

[0050] In some possible implementations, the detection module includes an infrared photoelectric liquid level sensor 212, the detection end of which is disposed on the inner wall of the first half-hole 211.

[0051] Specifically, the detection module includes an infrared photoelectric liquid level sensor 212, which determines whether there is liquid in the medium by the refractive index of the infrared light entering the medium. The detection end of the photoelectric liquid level sensor 212 emits infrared light into the detection channel. When there is no liquid medium, this beam of light will directly pass through the detection channel and reach the inner wall of the second half-hole 221. Due to the large incident angle, which exceeds the critical angle, the light will undergo total internal reflection at the medium interface. Therefore, most of the infrared light cannot be reflected to the receiving end. The light intensity detected by the receiving end is low, which indicates that there is no liquid in the infusion tube.

[0052] In some possible implementations, the inner wall of the first half-hole 211 and the inner wall of the first half-hole 211 are both provided with anti-slip strips; the mounting bracket 13 has an L-shaped structure.

[0053] Specifically, since the infusion tube is suspended vertically during use, the air detector 2 may slip or fall off due to gravity and some human manipulation. The anti-slip strip enhances the stability of the air detector 2 in holding the infusion tube, thereby improving the stability of the detection.

[0054] In some possible implementations, the pressurizing assembly 11 includes a first rotating plate 111, a plurality of push columns 112, and a second rotating plate 113. The first rotating plate 111 and the second rotating plate 113 are arranged in parallel. The first rotating plate 111 and the second rotating plate 113 are supported and connected by the plurality of push columns 112, and the plurality of push columns 112 are evenly arranged along the center of the first rotating plate 111 and the second rotating plate 113. The first rotating plate 111 is connected to a drive motor. The fixing assembly 12 includes a first mounting channel 121 and a second mounting channel 122, which are arranged in parallel.

[0055] Specifically, as shown in the figure, the pressurizing assembly 11 includes a first rotating plate 111, several push columns 112, and a second rotating plate 113. In use, the first rotating plate 111, several push columns 112, and the second rotating plate 113 are rotated as a whole by a drive motor. The connecting tube is made of elastic medical silicone rubber and is wound around several push columns 112 so that the connecting tube is pushed and pressurized by the rotation of several push columns 112, thereby increasing the delivery speed of the liquid in the connecting tube.

[0056] In some possible implementations, the detection unit 21 further includes an alarm module, which is communicatively connected to the detection module; the alarm module includes a buzzer alarm.

[0057] Specifically, by setting up the alarm module, when the detection module detects that the infusion tube is empty, the alarm module can sound an alarm to the outside world, promptly reminding medical staff to come and replace the infusion bag; as one possible way, the alarm module includes a buzzer alarm.

[0058] In some possible implementations, the detection unit 21 is also provided with a charging interface 213, which is electrically connected to a power supply device located inside the detection unit 21.

[0059] Specifically, the charging interface 213 facilitates the charging of the air detector 2.
