Description

Technical Field

[0001] This utility model relates to an air receiving device, and more particularly to an air receiving device for medical surgery. Background Technology

[0002] In the field of surgical medicine, gas connection devices are indispensable equipment. However, traditional gas connection devices are often cumbersome to operate, requiring medical staff to spend a significant amount of time and effort. This not only reduces surgical efficiency but also increases staff fatigue, thus affecting the quality of the surgery. Furthermore, in emergency surgeries or situations requiring rapid gas tube replacement, the complex operation of gas connection devices can become an obstacle, even endangering the patient's life. Simultaneously, traditional gas connection devices often suffer from insufficient airtightness during connection, leading to gas leaks, which not only waste valuable medical resources but also negatively impact the surgical procedure.

[0003] Therefore, there is an urgent need for a medical surgical air-contacting device to solve the technical problems existing in the above-mentioned prior art. Utility Model Content

[0004] This invention overcomes the shortcomings of the prior art and provides a gas receiving device for medical surgery.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a gas receiving device for medical surgery, comprising: a gas cylinder, a gas supply pipe, a gas receiving pipe, and a pressure reducing valve and a gas receiving port installed on the gas supply pipe; a fixing ring plate and a fixing cylinder are provided on one side of the gas receiving port, the gas receiving pipe is connected to the fixing cylinder, an inner sliding plate is slidably connected inside the fixing cylinder, a limiting mechanism is provided between the fixing ring plate and the fixing cylinder, the limiting mechanism includes a spring connected to the fixing ring plate and a limiting bolt connected to the spring; a sliding groove and a limiting hole are opened on the outer wall of one end of the gas receiving pipe, the sliding groove is connected to the limiting hole, and the limiting bolt is adapted to the limiting hole. Medical personnel only need to simply push the gas receiving pipe into the fixing cylinder, and the limiting bolt will automatically engage with the limiting hole to complete the connection, greatly saving surgical time.

[0006] In a preferred embodiment of this invention, a sealing gasket is provided at one end of the inner sliding plate, and the sealing gasket abuts against the air inlet tube. This effectively prevents gas leakage, thereby ensuring a stable gas supply during surgery and avoiding surgical risks caused by gas leakage.

[0007] In a preferred embodiment of this invention, the fixing ring plate is located outside the fixing cylinder, and both the fixing ring plate and the fixing cylinder are made of stainless steel. Stainless steel has high strength and is not easily deformed, ensuring the stability of the gas receiving device during long-term use. At the same time, stainless steel is easy to clean and disinfect, meeting the stringent hygiene requirements of medical surgery.

[0008] In a preferred embodiment of this utility model, the inner side of the inner sliding plate is provided with an inclined surface.

[0009] In a preferred embodiment of this invention, the sealing gasket is made of rubber. Rubber has good elasticity and sealing properties, enabling it to tightly seal the gap between the gas inlet pipe and the fixed cylinder, preventing gas leakage.

[0010] In a preferred embodiment of this invention, the air inlet tube is pushed into the fixed cylinder, and the limiting bolt, under the action of the spring, is engaged in the limiting hole, with the air inlet tube abutting against the sealing gasket, completing the installation step; rotating the air inlet tube moves the limiting bolt into the sliding groove, completing the disassembly step. Through simple pushing and rotating actions, the air inlet tube can be quickly installed and disassembled, greatly improving surgical efficiency.

[0011] In a preferred embodiment of this invention, the depth difference between the limiting hole and the sliding groove is 1-2 mm, the depth of the limiting hole is greater than the depth of the sliding groove, and the connection between the limiting hole and the sliding groove is smoothed. The depth difference between the limiting hole and the sliding groove ensures that the limiting bolt remains stable when inserted into the limiting hole and is not easily dislodged.

[0012] In a preferred embodiment of this utility model, the end of the air inlet pipe with the groove and the limiting hole is made of stainless steel.

[0013] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0014] (1) This utility model achieves quick installation and disassembly of the air connection tube by means of spring and limit bolt, which not only simplifies the complicated connection steps in the traditional air connection device, but also improves the convenience of operation. When in use, medical staff only need to push the air connection tube into the fixed cylinder, and the limit bolt will automatically lock into the limit hole to complete the connection, which greatly saves the operation time.

[0015] (2) By setting an inner sliding plate and a sealing gasket, this utility model can tightly fit the gap between the air inlet tube and the fixed tube, thereby effectively preventing gas leakage. This not only ensures a stable gas supply during the operation, but also avoids the surgical risks caused by gas leakage. Attached Figure Description

[0025] like Figure 1 and Figure 2 As shown, a medical surgical gas receiving device includes: a gas cylinder 1, a gas supply pipe 2, a gas receiving pipe 5, and a pressure reducing valve 3 and a gas receiving port 4 installed on the gas supply pipe 2; a fixing ring plate 6 and a fixing cylinder 7 are provided on one side of the gas receiving port 4, the gas receiving pipe 5 is connected to the fixing cylinder 7, an inner sliding plate 8 is slidably connected inside the fixing cylinder 7, a limiting mechanism is provided between the fixing ring plate 6 and the fixing cylinder 7, the limiting mechanism includes a spring 11 connected to the fixing ring plate 6 and a limiting bolt 12 connected to the spring 11; a sliding groove 9 and a limiting hole 10 are opened on the outer wall of one end of the gas receiving pipe 5, the sliding groove 9 and the limiting hole 10 are connected, and the limiting bolt 12 is adapted to the limiting hole 10.

[0026] like Figure 3 As shown, a sealing gasket 13 is provided at one end of the inner sliding plate, and the sealing gasket 13 abuts against the air inlet pipe 5. The fixing ring plate 6 is located on the outside of the fixing cylinder 7, and both the fixing ring plate 6 and the fixing cylinder 7 are made of stainless steel. The inner side of the inner sliding plate 8 is provided with a slope. The sealing gasket 13 is made of rubber.

[0027] Push the air inlet pipe 5 into the fixed cylinder 7. Under the action of the spring 11, the limit bolt 12 is inserted into the limit hole 10, and the air inlet pipe 5 abuts against the sealing gasket 13, completing the installation step; rotate the air inlet pipe 5, and the limit bolt 12 moves into the slide groove 9, completing the disassembly step.

[0028] The depth difference between the limiting hole 10 and the slide groove 9 is 1-2 mm, and the depth at the limiting hole 10 is greater than the depth at the slide groove 9. The connection between the limiting hole 10 and the slide groove 9 is smoothed. The end of the air inlet pipe 5 with the slide groove 9 and the limiting hole 10 is made of stainless steel.

[0029] In use, the main body of this device consists of a gas cylinder 1, a gas supply pipe 2, a gas inlet pipe 5, a pressure reducing valve 3 and a gas inlet port 4 installed on the gas supply pipe 2. A fixing ring plate 6 and a fixing cylinder 7 are provided on one side of the gas inlet port 4 to ensure a stable connection with the gas inlet pipe 5.

[0030] During the connection process, the air inlet pipe 5 is pushed into the fixed cylinder 7. At this time, the inner sliding plate 8, which is slidably connected inside the fixed cylinder 7, will move accordingly. Simultaneously, the limiting mechanism set between the fixed ring plate 6 and the fixed cylinder 7 begins to extend and retract. The limiting mechanism consists of a spring 11 connected to the fixed ring plate 6 and a limiting bolt 12 connected to the spring 11. When the air inlet pipe 5 is pushed into place, the limiting bolt 12, under the elastic force of the spring 11, will engage with the limiting hole 10 opened on the outer wall of one end of the air inlet pipe 5, thereby completing the initial fixation.

[0031] In addition, a sealing gasket 13 is provided at one end of the inner slide plate 8. When the air inlet pipe 5 is pushed in and abuts against the sealing gasket 13, the airtightness of the connection can be ensured. If it is necessary to disassemble the air inlet pipe 5, simply rotate the air inlet pipe 5 to move the limiting bolt 12 out of the limiting hole 10 and into the slide groove 9 to complete the disassembly step. At this time, the inner slide plate 8 uses the inclined surface provided on its inner side to guide the limiting bolt 12 back to the initial position.

[0032] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
