Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a chin support breathing mask for MECT anesthesia. Background Art

[0002] At present, the commonly used anesthesia masks in medical treatment often cause the tongue root to fall back during anesthesia, resulting in difficulty or even no ventilation due to the use of muscle relaxants or the patient's own tongue hypertrophy. The solution at this time is to lift the patient's mandible to relieve the obstruction of the upper airway.

[0003] When a single medical staff member uses an anesthesia mask, they generally use the EC technique, pressing the mask with the thumb and index finger, and holding the patient's lower jaw with the remaining three fingers to lift it up. This action requires long-term force from the fingers, which is not only laborious, but also easily causes the mask to move and cause air leakage. It is especially difficult to accomplish for female medical staff with smaller hands and less strength. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a chin support breathing mask for MECT anesthesia to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The solution of the present invention to solve its technical problem is:

[0006] A chin support breathing mask for MECT anesthesia, comprising:

[0007] Mask body;

[0008] A pressure structure, wherein the pressure structure is slidably connected to the mask body, the pressure structure can slide up and down relative to the mask body, and the pressure structure is protruded with a connecting pipe, and the connecting pipe is connected to the mask body;

[0009] The mandibular support hook is slidably connected to the mask body, and the two ends of the mandibular support hook are respectively set as a control end and a mandibular support end, and the control end is fixed to the pressure structure; when the pressure structure moves upward relative to the mask body, the mandibular support end is driven to approach the mask body.

[0010] As a further improvement of the above technical solution, a sealing structure is provided at the edge of the mask body, and the sealing structure is an elastic component, and the sealing structure is used to deform and fit the patient's skin.

[0011] As a further improvement of the above technical solution, a palm abutting protrusion is provided at the upper end of the mask body, and the palm abutting protrusion is used to abut against the palm of the medical staff to apply a force toward the patient's face to the upper end of the mask body.

[0012] As a further improvement of the above technical solution, a soft cushion layer is fixed to the outer peripheral surface of the palm-abutting protrusion.

[0013] As a further improvement of the above technical solution, the mandibular hook includes a hook body, a connector and a hook elastic member. The hook body is hinged to the end of the connector, and the hook elastic member is arranged between the hook body and the connector. The hook elastic member is used to drive the hook body to swing relative to the connector, so that the angle between the hook body and the connector is reduced.

[0014] As a further improvement of the above technical solution, a pressing portion is provided at an end of the hook body away from the connecting body, and the pressing portion protrudes toward the mask body.

[0015] As a further improvement of the above technical solution, a pressure resetting structure is provided between the pressure structure and the mask body, and the pressure resetting structure is used to drive the pressure structure to be reset downward relative to the mask body.

[0016] As a further improvement of the above technical solution, the pressure-applying structure is installed with a clamping and locking structure, and the clamping and locking structure includes a locking drive and a clamping member. The locking drive is provided with an operating part and a threaded part, and the threaded part is threadedly connected to the pressure-applying structure. The clamping member is arranged at one end of the locking drive close to the mask body, and the clamping member is used to abut against the outer peripheral surface of the mask body to realize the locking of the pressure-applying structure and the mask body.

[0017] As a further improvement of the above technical solution, the compression locking structure also includes a compression reset structure, which is arranged between the compression member and the pressure structure, and the compression reset structure enables the compression member to always have a tendency to move away from the mask body.

[0018] As a further improvement of the above technical solution, the operating portion is provided with anti-slip grooves.

[0019] The beneficial effects of the present invention are as follows: when the pressure structure moves upward relative to the mask body, the mandibular support hook will approach the patient's mandible. When the pressure structure moves to a certain position, the mandibular support hook supports the patient's mandible, the lower end of the mask body is pressed by the mandibular support hook and the mask body itself, and the upper end of the mask body is pressed by the force applied by medical staff. For the breathing mask of this scheme, medical staff only need to press the upper end of the mask body to achieve the sealing between the mask body and the patient's skin. Compared with the EC technique used in the prior art, it can reduce the workload of medical staff and is not easy to leak.

[0028] Reference Figure 1 and Figure 2 A chin support breathing mask for MECT anesthesia includes a mask body 100, a pressure-applying structure 200 and a chin support hook 300.

[0029] The mask body 100 is similar to a conventional breathing mask structure, and is used to cover the patient's nose and mouth so that the anesthetic gas can be smoothly inhaled by the patient. This solution makes certain improvements on the original structure of the mask body 100 to adapt to the pressure structure 200 and the mandibular support hook 300.

[0030] Specifically, a sealing structure 110 is provided at the edge of the mask body 100. The sealing structure 110 is an elastic deformable component. The sealing structure 110 can be set as a medical silicone component or an airbag or other structure. Those skilled in the art can select the specific structure of the sealing structure 110 according to actual needs. When using the MECT anesthesia chin support breathing mask, the sealing structure 110 is in contact with the patient's skin structure. When the medical staff applies a force toward the patient to the mask body 100, the sealing structure 110 is deformed and closely fits the patient's skin, thereby ensuring the sealing of the mask body 100.

[0031] The mask body 100 is provided with ventilation holes.

[0032] Specifically, in this embodiment, a palm abutting protrusion 120 is further protruded from the upper end of the mask body 100 .

[0033] Specifically, in this embodiment, a soft cushion layer is fixedly provided on the outer peripheral surface of the palm-contacting protrusion 120, and the soft cushion layer is used to contact the hands of medical staff, thereby preventing the hands of medical staff from contacting relatively hard objects for a long time, thereby reducing the discomfort of medical staff when using a breathing mask on patients for a long time.

[0034] The palm abutting protrusion 120 is used to abut against the protruding structure at the intersection of the palm and wrist of the medical staff, so that the medical staff can better apply a force toward the patient to the upper end of the mask.

[0035] The pressure structure 200 is slidably connected to the mask body 100. A deformable sheet structure is fixedly provided at one end of the pressure structure 200 close to the mask body 100. The sheet structure is set as a first guide sheet 220. A first guide rail 130 is fixedly provided on the periphery of the mask body 100. The number of the first guide rails 130 is set to two. The two first guide rails 130 are symmetrically arranged on the left and right sides of the first guide sheet 220. The first guide rail 130 extends up and down along the periphery of the mask body 100, so that the first guide rail 130 presents a curved bending structure. The end of the first guide sheet 220 is arranged in the first guide sheet 130, and the first guide sheet 220 is slidably connected to the first guide rail 130. The first guide sheet 220 and the first guide rail 130 guide the pressure structure 200, so that the pressure structure 200 can move up and down along the periphery of the mask body 100.

[0036] A connecting tube 210 is protruding from one end of the pressure structure 200 away from the mask body 100, and the connecting tube 210 is connected to the mask body 100 through a vent. In this solution, the connecting tube 210 is used to connect to an external gas supply device to provide the patient with gas for breathing and anesthesia. At the same time, the medical staff can adjust the relative position of the pressure structure 200 and the mask body 100 by pulling the connecting tube 210 to achieve the movement of the pressure structure 200, and can also prevent the medical staff's hands from accidentally separating from the pressure structure 200 due to slipping.

[0037] Specifically, in this embodiment, a pressure reset structure 201 is provided between the pressure structure 200 and the mask body 100, and the pressure reset structure 201 is provided as a coil spring. When the pressure structure 200 moves upward relative to the mask body 100, the pressure reset structure 201 accumulates elastic potential energy. When the medical staff cancels the upward force applied to the pressure structure 200 relative to the mask body 100, the pressure reset structure 201 releases the elastic potential energy, so that the pressure structure 200 automatically moves downward relative to the mask body 100, so that the pressure structure 200 is reset. In other embodiments, the pressure reset structure 201 may also be provided as other commonly used elastic components such as a spring sheet, and those skilled in the art may select the specific structure of the pressure reset structure 201 according to actual needs.

[0038] Specifically, in this embodiment, a compression and locking structure 400 is disposed between the pressure-applying structure 200 and the mask body 100. The compression and locking structure 400 includes a compression member 410, a locking driving member 420 and a compression and reset structure 430.

[0039] The locking drive member 420 is provided with a threaded portion 421 and an operating portion 422, and the threaded portion 421 and the operating portion 422 are fixedly arranged with each other. The locking drive member 420 is an annular structure, and the locking drive member 420 is sleeved on the connecting tube 210. The threaded portion 421 is arranged on the inner side of the locking drive member 420, and the outer peripheral surface of the connecting tube 210 is provided with a threaded structure, and the threaded portion 421 is threadedly connected with the threaded structure on the outer peripheral surface of the connecting tube 210. Specifically, in this embodiment, the operating portion 422 is provided with an anti-skid pattern 423. By providing the anti-skid pattern 423 on the operating portion 422, it can be prevented that the medical staff will slip when driving the locking drive member 420 to rotate.

[0040] The pressing member 410 is slidably connected to the pressure structure 200 along a first direction, and the pressing member 410 includes a connecting ring 411 and a plurality of connecting portions 412 arranged at circumferential intervals. The connecting portion 412 is fixedly connected to the connecting ring 411, and the connecting portion 412 passes through the pressure structure 200. The connecting ring 411 is used to abut against the end surface of the locking drive member 420 toward the mask body 100, so that the locking drive member 420 can drive the pressing member 410 to move. When the locking drive member 420 moves in a direction close to the mask body 100, the pressing member 410 will move in a direction close to the mask body 100 with the locking drive member 420. After the pressing member 410 is tightly abutted against the outer peripheral surface of the mask body 100, the locking of the pressure structure 200 and the mask body 100 can be completed by the friction between the connecting portion 412 and the mask body 100.

[0041] The compression reset structure 430 is arranged between the compression piece 410 and the pressure structure 200. The compression reset structure 430 is arranged as a coil spring. When the compression piece 410 is pushed by the locking driving piece 420 and approaches the mask body 100, the compression reset structure 430 accumulates elastic potential energy. When the locking driving piece 420 moves away from the mask body 100, the compression reset structure 430 drives the compression piece 410 away from the mask body 100 to release the locking of the pressure structure 200 and the mask body 100.

[0042] Setting the locking drive member 420 as a ring structure and sleeve the locking drive member 420 on the connecting tube 210 can make the operation of the medical staff more convenient. Since the medical staff needs to use their hands to grasp or use the tiger's mouth to hold the connecting tube 210 when driving the pressure structure 200, after the pressure structure 200 is moved into place, the medical staff can directly use their hands to rotate the locking drive member 420 without having to separate their hands from the connecting tube 210 and then operate the locking drive member 420, so that the medical staff's operation can be completed in one go, which can effectively improve the work efficiency of the medical staff.

[0043] The mandibular support hook 300 is slidably connected to the mask body 100, and the mandibular support hook 300 is arranged below the pressure-applying structure 200. The two ends of the mandibular support hook 300 are respectively set as a mandibular support end and a control end.

[0044] The mandibular hook 300 includes a connecting body 310, a hook elastic member 320 and a hook body 330. The control end is the end of the connecting body 310, the part of the connecting body 310 close to the pressure structure 200 is a deformable sheet structure, and the part away from the pressure structure 200 is a rigid sheet structure, and the outer peripheral surface of the mask body 100 is fixedly provided with a second guide rail 140, corresponding to the connecting body 310, the second guide rail 140 is provided with a bending section and a straight section, the rigid part of the connecting body 310 is always located in the straight section of the second guide rail 140 for sliding, and the deformable part of the connecting body 310 passes through the bending section and the straight section, so that the connecting body 310 can work normally. The number of the second guide rails 140 is set to two, and the two second guide rails 140 are symmetrically arranged on the left and right sides of the chin hook 300. The second guide rails 140 extend up and down along the periphery of the mask body 100. The connecting body 310 is fixedly connected to the pressure structure 200. When the pressure structure 200 moves up and down relative to the mask body 100, the chin hook 300 will move up and down relative to the mask body 100 with the pressure structure 200.

[0045] The hook body 330 is arranged at one end of the connector 310 away from the pressure structure 200, and the hook body 330 is hingedly connected to the connector 310. The hook body 330 and the connector 310 are arranged at an angle, and the angle between the hook body 330 and the connector 310 is less than 60°. The end of the hook body 330 away from the connector 310 is set as a mandibular support end. The mandibular support end is used to support the patient's mandible to avoid the medical staff from using the EC technique (i.e., using the middle finger, ring finger and little finger to support the patient's mandible, and the index finger and thumb to press the mask) to keep supporting the patient's mandible, thereby reducing the fatigue of the medical staff's fingers.

[0046] The hook elastic member 320 is disposed between the hook body 330 and the connecting body 310. The hook elastic member 320 is configured as an arc-shaped spring sheet structure. The hook elastic member 320 is disposed on the side of the hook body 330 and the connecting body 310 away from the mask. The hook elastic member 320 is used to drive the hook body 330 to swing relative to the connecting body 310, so that the angle between the hook body 330 and the connecting body 310 is reduced. In other embodiments, the hook elastic member 320 may also be configured as a spiral spring structure, and the position of the hook elastic member 320 and the connection method with other components may be adjusted according to the specific structure of the hook elastic member 320. Those skilled in the art may select the specific structure of the hook elastic member 320 according to actual needs.

[0047] When the mandibular support hook 300 moves upward, the distance between the hook body 330 and the mask body 100 is reduced, and the end of the hook body 330 will abut against the patient's mandible. At this time, the angle between the hook body 330 and the connecting body 310 becomes larger, and the hook elastic member 320 accumulates elastic potential energy, so that the hook body 330 always has a tendency to swing and reset relative to the connecting body 310. The hook elastic member 320 provides a force to support the patient's mandible to ensure that the hook body 330 can lift the patient's mandible normally.

[0048] Specifically, in this embodiment, one end of the hook body 330 away from the connector 310 is protruded with a pressing portion 331, and the pressing portion 331 protrudes toward the mask body 100. The pressing portion 331 is used to push the patient's hyoid bone inward, so that the tongue of the patient will not fall back into the respiratory tract and block the patient's respiratory passage after anesthesia, thereby ensuring that the patient breathes gas normally.

[0049] The mandibular support hook 300 of the present solution can be adjusted relative to the mask body 100 so that the respiratory mask can be adapted to patients with different face shapes, thereby effectively improving the adaptability of the respiratory mask.

[0050] The use process of the breathing mask in this scheme is:

[0051] The medical staff first places the mask body 100 on the patient's face so that the mask body 100 covers the patient's nose and mouth. Then the medical staff grasps the connecting tube 210 with their hands or holds the connecting tube 210 with their thumb and thumb, and pulls the connecting tube 210 to move upward relative to the mask body 100, so that the pressure structure 200 moves upward relative to the mask body 100, thereby driving the mandibular support hook 300 to move.

[0052] During the upward movement of the mandibular support hook 300 relative to the mask body 100, the support hook body 330 gradually approaches the patient's mandible until the support hook body 330 abuts against the end surface of the patient's mandible facing the mask body 100, and at this time, the pressing portion 331 lifts the patient's hyoid bone. After the mandibular support hook 300 supports the patient's mandible, the medical staff locks the relative positions of the pressure structure 200 and the mask body 100 by pressing the locking structure 400, thereby preventing the medical staff from applying a force to the pressure structure 200 and the connecting tube 210 for a long time to overcome the elastic force of the pressure reset structure 201, thereby reducing the workload of the medical staff.

[0053] Then the medical staff continues to pull the connecting tube 210, and the mandibular support hook 300 supports the patient's mandible and gradually tilts the patient's head, thus completing the mandibular lifting of the patient. The lower end of the mask body 100 is pressed by the mandibular support hook 300 and the mask body 100 itself, and the upper end of the mask body 100 is pressed by the medical staff. The medical staff only needs to press the upper end of the mask body 100 to achieve the sealing between the mask body 100 and the patient's skin. Compared with the EC technique used in the prior art, it can reduce the workload of the medical staff and is not easy to leak.

[0054] When the operation is completed, the medical staff operates the compression locking structure 400 to make the locking positions of the pressure structure 200 and the mask body 100 contact, and the pressure structure 200 will automatically reset due to the elastic force of the pressure reset structure 201, thereby driving the mandibular support hook 300 to move, so that the mandibular support hook 300 is away from the patient's mandible, and then the breathing mask can be separated from the patient.

[0055] Compared with other masks with mandibular support structures, the mandibular support hook 300 of this solution can fit the patient's mandible more closely, can provide better mandibular support, and the mask body 100 can have better airtightness.

[0056] The preferred embodiments of the present invention are described in detail above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
