An oxygen mask for surgery

Abstract

This invention discloses a surgical oxygen mask, relating to the field of surgical medical device technology. It includes a mask body and an oxygen inlet body, with multiple oxygen inlet channels on the oxygen inlet body. A rotating column is mounted on the mask body, one end of which is rotatably connected to the mask body, while the other end passes freely through the oxygen inlet body. The multiple oxygen inlet channels are evenly distributed circumferentially around the rotating column. A blocking groove is provided within the oxygen inlet body to separate the oxygen inlet channels. A blocking disc, which cooperates with the blocking groove, is mounted on the rotating column, and the blocking disc has a guide port. The rotating column and blocking disc allow for rapid switching between different oxygen inlet modes. Furthermore, because the auxiliary equipment is directly connected to the oxygen mask, losses caused by medication and pressure within the oxygen delivery pipeline during oxygen inlet are reduced. The rapid switching function also avoids interference between different oxygen inlet modes, greatly improving the convenience of surgery and demonstrating strong practicality.

Description

Technical Field

[0001] This invention relates to the field of surgical medical devices, and in particular to a surgical oxygen mask. Background Technology

[0002] During surgery, most anesthetic drugs suppress respiratory function, and patients requiring emergency resuscitation may experience respiratory arrest. Since the human body has a very low tolerance for hypoxia, hypoxia in vital organs such as the heart and brain is a major cause of death. Therefore, oxygen therapy is very important in anesthesia, surgery, and emergency resuscitation.

[0003] An oxygen mask provides a way to transfer the oxygen needed for breathing from a tank to the lungs. It is an essential device in oxygen therapy and plays an important role in ensuring patient safety. It is mainly made of plastic, silicone or rubber.

[0004] During surgery, different oxygen supply modes are required when patients experience insufficient oxygen supply, regain spontaneous oxygen intake, require supplemental anesthetic drugs, or need humidified oxygen delivery. Taking the regaining of spontaneous oxygen intake as an example, in current surgeries, due to the limited adjustable range of the equipment (i.e., the oxygen supply frequency and cycle of the oxygen concentrator), surgeons often need to use a hand-held airbag connected to the oxygen mask to increase the frequency of oxygen supply. However, the connection between the hand-held airbag and the oxygen mask is mostly achieved by setting a "Y"-shaped tube at the oxygen supply pipeline, connecting the oxygen supply pipeline and the hand-held airbag to the oxygen mask through the "Y"-shaped tube. Because there is a long oxygen supply pipeline between the "Y"-shaped tube and the oxygen mask, it is difficult for the squeezing pressure of the hand-held airbag to be quickly fed back to the oxygen mask. Similarly, when supplemental anesthetic drugs are needed, the anesthetic, after being nebulized, needs to flow through the oxygen supply pipeline synchronously with the oxygen supply from the oxygen concentrator, and it is also prone to condensation in the pipeline. The feedback time to the oxygen mask is long, and the anesthetic effect is difficult to control.

[0005] In addition, when switching between different oxygen supply modes, the auxiliary liquid remaining in the pipeline can also affect the oxygen supply effect. Summary of the Invention

[0006] The purpose of this invention is to provide a surgical oxygen mask that facilitates switching of oxygen delivery modes.

[0007] The technical solution adopted in this invention is as follows:

[0008] A surgical oxygen supply mask includes a mask body with a switching device. The switching device includes an oxygen inlet body with multiple oxygen inlet channels. The oxygen inlet channels are connected to the interior of the mask body. A rotating column is provided on the mask body, one end of which is rotatably connected to the mask body, and the other end of which is freely disposed through the oxygen inlet body. The multiple oxygen inlet channels are evenly distributed circumferentially around the rotating column. A blocking groove is provided inside the oxygen inlet body to separate the oxygen inlet channels. A blocking plate that cooperates with the blocking groove is provided on the rotating column, and the blocking plate has a guide port. An intermediate tube is connected to each oxygen inlet channel, and multiple intermediate tubes are connected to each other. An oxygen inlet pipe is also connected to each intermediate tube. The solution, through the setting of multiple oxygen supply channels and a switching device, can turn the guide port on the barrier plate toward different oxygen supply channels by rotating the rotating column, and connect different auxiliary devices through the intermediate tube, thereby quickly switching between different oxygen supply modes. At the same time, since the auxiliary devices are directly connected to the oxygen supply mask, the loss of drugs, pressure and other factors caused by the oxygen supply pipeline during the oxygen supply process is reduced. The rapid switching function also avoids interference between different oxygen supply modes, greatly improving the convenience of surgery and making it highly practical.

[0009] Preferably, the oxygen supply channel includes a main channel, a resuscitation channel, and an auxiliary channel. A resuscitation tube is connected to the intermediate tube corresponding to the resuscitation channel, and a hand-held cuff is connected to the free end of the resuscitation tube. An auxiliary tube is connected to the intermediate tube corresponding to the auxiliary channel, and a nebulizer is connected to the free end of the auxiliary tube. The arrangement of the resuscitation channel, resuscitation tube, and hand-held cuff allows for adjustment of the oxygen supply frequency by holding the cuff when the resuscitation tubing is connected at the inlet, facilitating the patient's return to spontaneous oxygen supply. The nebulizer allows for the atomization of auxiliary fluids (such as anesthetic solutions, distilled water, or saline solution) and their introduction into the auxiliary channel for respiratory circulation.

[0010] It is worth mentioning that the resuscitation tube and auxiliary tube can be set to a thinner tube in actual use to ensure that the squeezing pressure of the hand-held airbag is quickly fed back to the oxygen mask.

[0011] Preferably, the oxygen inlet tube is disposed on the intermediate tube corresponding to the main channel, and a suction port is provided on the oxygen inlet tube along the direction of the main channel. In the structural design, the oxygen inlet tube disposed on the main channel is positioned above the patient's mouth after wearing a mask, and the suction port is provided to suction out sputum from the patient's mouth and throat, preventing it from affecting the patient's oxygen intake.

[0012] Preferably, both the resuscitation channel and the intermediate tube corresponding to the auxiliary channel are equipped with a first one-way valve. The first one-way valve is suitable for sealing the resuscitation channel and the auxiliary channel towards the oxygen inlet tube. The first one-way valve can prevent functional fluid from entering the oxygen inlet tube during nebulization of auxiliary fluid, ensuring that the functional fluid enters the patient's respiratory cycle as much as possible and improving its effectiveness. Similarly, when spontaneous oxygen inhalation is restored, it can prevent the pressure of the hand-held cuff from being affected by the pressure inside the oxygen inlet tube, making it highly practical.

[0013] Preferably, the first one-way valve includes a mesh plate and an annular baffle. A sealing ball is disposed between the mesh plate and the annular baffle. The mesh plate has multiple communication ports and is positioned away from the oxygen inlet pipe. The sealing ball cooperates with the annular baffle to seal the intermediate pipe. The arrangement of the annular baffle, mesh plate, and sealing ball ensures that when oxygen is introduced into the oxygen inlet pipe, the sealing ball is pushed against the mesh plate, allowing free oxygen intake. When the hand-held airbag is pressurized or the functional liquid is atomized, the sealing ball is pushed against the annular baffle to seal, preventing it from entering the oxygen inlet pipe and further ensuring practical effectiveness.

[0014] Preferably, the free end of the rotating column is provided with a rotating block, and an indicator block is provided on the rotating block facing the guide port. The indicator block on the rotating block facilitates the surgeon's observation and adjustment of the current oxygen supply mode, making it convenient to use.

[0015] Preferably, a contact pad made of elastic material is wound around the side wall of the mask. A fixing strap is also provided on the contact pad, with one end connected to the fixing strap and the other end having a locking block for engaging the fixing strap. The contact pad, made of elastic material, is used to contact the patient's face, improving comfort. The fixing strap and locking block are used to secure the oxygen mask to the patient's face. There are numerous existing locking methods for the locking block; a suitable method from the prior art can be directly selected. Since this is not the focus of this application, it will not be elaborated upon here.

[0016] Preferably, the contact pad has a filling cavity, the fixing band has a locking cavity communicating with the filling cavity, and the fixing band also has an inflation tube communicating with the filling cavity, with an inflation device at the free end of the inflation tube. The filling cavity in the contact pad, after inflation by the inflation device, allows for a better fit to the patient's face, preventing oxygen leakage and ensuring oxygen supply. The locking cavity on the fixing band allows for inflation by the inflation device after the mask is put on, ensuring a good fit and preventing the mask from falling off during surgery.

[0017] Preferably, the inflation device includes a pressure bladder connected to the free end of the inflation tube. A second one-way valve is provided inside the inflation tube, guiding the pressure bladder towards the locking cavity. A replenishment tube, connecting the inflation tube to the pressure bladder, is also provided between the second one-way valve and the pressure bladder. The replenishment tube is connected to the outside environment, and a third one-way valve is provided inside the replenishment tube, guiding the outside environment towards the inflation tube. A vent is also provided near the fixing strap on the inflation tube, and a sealing plug is provided on the vent. The pressure bladder is used to pressurize the filling cavity and the locking cavity. The second one-way valve, without affecting the pressurization process, prevents backflow of gas from the filling cavity and locking cavity when the pressure bladder re-inflates. The replenishment tube and the third one-way valve are used to replenish gas when the pressure bladder re-inflates and prevent gas from flowing out of the replenishment tube during compression. The vent is used to release gas after surgery, allowing the oxygen mask to be removed, making it convenient to use.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. In this invention, by setting up multiple oxygen inlet channels and a switching device, the guide port on the barrier plate can be oriented towards different oxygen inlet channels by rotating the rotating column, and different auxiliary devices can be connected through the intermediate pipe, thereby quickly switching between different oxygen inlet modes. At the same time, since the auxiliary devices are directly connected to the oxygen supply mask, the loss of drugs, pressure, etc. in the oxygen supply pipeline during the oxygen supply process is reduced. The function of rapid switching also avoids interference between different oxygen inlet modes, greatly improving the convenience of surgery and making it highly practical.

[0020] 2. In this invention, the first one-way valve prevents the functional fluid from entering the oxygen inlet tube during the nebulization of the auxiliary fluid, ensuring that the functional fluid enters the patient's respiratory cycle as much as possible and improving its effect. Similarly, when the patient resumes spontaneous oxygen inhalation, the pressure of the hand holding the cuff is prevented from being affected by the pressure inside the oxygen inlet tube, making it highly practical.

[0021] 3. In this invention, the filling cavity in the contact pad allows for better fit to the patient's face after inflation via the inflation device, preventing oxygen leakage and ensuring oxygen supply. The locking cavity on the fixing strap allows for inflation via the inflation device after the mask is put on, ensuring the wearing effect and preventing the mask from falling off during surgery.

[0022] 4. In this invention, the pressure bag is used to pressurize the filling chamber and the locking chamber. The second one-way valve is used to prevent the gas in the filling chamber and the locking chamber from flowing back when the pressure bag returns to air, without affecting the pressurization process. The gas supply tube and the third one-way valve are used to replenish gas when the pressure bag returns to air, and to prevent gas from flowing out of the gas supply tube when squeezed. The vent is used to release gas after the operation and remove the oxygen mask, making it convenient to use. Attached Figure Description

An oxygen inlet tube 9 is also connected to the intermediate tube 8; the oxygen inlet channel 3 includes a main channel 10, a resuscitation channel 11, and an auxiliary channel 12. A resuscitation tube 13 is connected to the intermediate tube 8 corresponding to the resuscitation channel 11. A hand-held airbag 14 is connected to the free end of the resuscitation tube 13. An auxiliary tube 15 is provided to the intermediate tube 8 corresponding to the auxiliary channel 12. A nebulizer is connected to the free end of the auxiliary tube 15; the oxygen inlet tube 9 is provided on the intermediate tube 8 corresponding to the main channel 10, and the oxygen inlet tube 9 extends along the main channel 10. A suction port 16 is provided in the direction of channel 10; a first one-way valve 17 is provided on both the resuscitation channel 11 and the intermediate tube 8 corresponding to the auxiliary channel 12. The first one-way valve 17 is suitable for sealing the resuscitation channel 11 and the auxiliary channel 12 in the direction of the oxygen inlet tube 9; the first one-way valve 17 includes a mesh plate 18 and an annular baffle 19, and a sealing ball 20 is provided between the mesh plate 18 and the annular baffle 19. The mesh plate 18 is provided with multiple communication ports 21. The mesh plate 18 is located away from the oxygen inlet tube 9. The sealing ball 20 is used to cooperate with the annular baffle 19 to seal the intermediate tube 8; a rotating block is provided at the free end of the rotating column 4. 22. An indicator block 23 is provided on the rotating block 22 facing the guide port 7; a contact pad 24 is wrapped around the side wall of the cover 1. The contact pad 24 is made of elastic material. A fixing band 25 is also provided on the contact pad 24. One end of the contact pad 24 is connected to the fixing band 25. A locking block 26 for engaging the fixing band 25 is provided on the other end of the contact pad 24; a filling cavity 27 is provided inside the contact pad 24; a locking cavity 28 communicating with the filling cavity 27 is provided inside the fixing band 25; an inflation tube 29 communicating with the filling cavity 27 is also provided on the fixing band 25. An inflation device is provided at the free end of the inflation tube 29.The inflation device includes a pressure bladder 30 connected to the free end of the inflation tube 29. A second one-way valve 31 is provided inside the inflation tube 29, guiding the pressure bladder 30 toward the locking cavity 28. A supplementary air tube 32, connecting the inflation tube 29 and the pressure bladder 30, is also provided between the second one-way valve 31 and the pressure bladder 30.

A vent 34 is also provided near the fixing strap 25 on the inflation tube 29, and a sealing plug 35 is provided on the vent 34.

[0035] Before the operation, the fixation strap 25 is passed through the back of the patient's head and locked by the locking block 26. Then, the pressure bag 30 is pressed repeatedly. The pressure bag 30 introduces gas from the inflation tube 29 into the filling chamber 27 and the locking chamber 28, which improves the locking effect. At the same time, the contact pad 24 is pressed tightly against the patient's face to complete the wearing. Then, the oxygen supply machine is connected to the oxygen inlet tube 9 and the nebulizer is connected to the auxiliary tube 15 to complete the preparation.

[0036] During the surgery, the oxygen supply machine is turned on. Under normal conditions, oxygen is introduced into the main channel 10 through the oxygen inlet tube 9, enters the hood 1, and is inhaled by the patient, ensuring the patient's oxygen supply. In case of an emergency requiring additional anesthetic, the anesthetic is placed in the nebulizer, and then the rotating block 22 is turned so that the indicator block 23 faces the auxiliary channel 12. At this time, oxygen will enter the auxiliary channel 12 through the oxygen inlet tube 9, mix with the nebulized anesthetic, and then enter the patient's systemic circulation. After the anesthetic replenishment is complete, the rotating block 22 is turned again so that the indicator block 23 faces the main channel 10, and the surgery can continue. (If the patient requires additional oxygen...) When ingesting other functional fluids, such as distilled water or saline, only different auxiliary fluids need to be added. When the patient experiences sputum outflow or sputum blockage, sputum from the patient's mouth and throat can be suctioned out through the suction port 16 to avoid affecting the patient's oxygen intake. After the operation, when the patient needs to resume independent oxygen intake, rotate the rotating block 22 so that the indicator block 23 faces the recovery channel 11. Then, the surgeon controls the frequency of pressing the hand-held air bag 14 according to the patient's recovery until the operation is completed. Finally, remove the sealing plug 35 and remove the oxygen mask after the gas in the filling chamber 27 and locking chamber 28 is expelled.
