Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a device for preventing the tongue root of a patient from falling back after anesthesia. Background Art

[0002] In order to prevent the patient's blood oxygen from decreasing during abortion, gastroenteroscopy, hysteroscopy and other non-intubation intravenous anesthesia, medical staff are required to hold the patient's mandibular angle to keep the patient's head up and avoid a decrease in blood oxygen concentration.

[0003] The main defect is that medical staff are required to support the patient throughout the whole process, and the medical staff cannot free their hands, resulting in a waste of manpower. Utility Model Content

[0004] In view of the above problems, a device is now provided for preventing the tongue root from falling back after anesthesia, aiming to solve the problems existing in the prior art.

[0005] The specific technical solutions are as follows:

[0006] A device for preventing the tongue root of a patient from falling back after anesthesia comprises a headrest body, a neck support assembly and a mandibular lifting assembly, wherein the headrest body is provided with a depression fitting the head on the front side, the mandibular lifting assembly is provided on the headrest body, and the neck support assembly is provided separately from the headrest body. When the patient's head is placed in the depression on the headrest body, the mandibular lifting assembly is located exactly at the patient's mandible, and the mandibular lifting assembly can be adjusted to lift the patient's mandible, and the neck support assembly is located exactly below the patient's neck.

[0007] The above-mentioned device for preventing the tongue root from falling back after anesthesia also has the following characteristics: the mandibular lifting assembly includes two lifting arms, a one-way adjustment part and a restoration part, the headrest body is hollow, the one-way adjustment part and the restoration part are both arranged in the headrest body, and the one-way adjustment part is transmission-connected with the restoration part, the two power ends of the one-way adjustment part respectively pass through the inner side walls on both sides of the headrest body and extend to the outside of the headrest body, and the two lifting arms are respectively connected to the two power ends of the one-way adjustment part.

[0008] The beneficial effects of the above scheme are as follows: the two lifting arms can lift the patient's lower jaw when they rotate and rise, and the one-way adjustment part limits the lifting arms from falling. When the lifting arms need to be lowered, the one-way adjustment part can be restored by the restoration part, and the lifting arms can be lowered.

[0009] The above-mentioned device for preventing the tongue root from falling back after anesthesia also has the following characteristics: the lifting arm includes a rotary arm and a lifting arm, one end of the rotary arm is connected to the power end of the one-way adjustment part, the other end of the rotary arm is provided with a threaded hole, and one end of the lifting arm is provided with an external thread matched with the threaded hole. When one end of the lifting arm is threadedly connected to the rotary arm, the lifting arm and the rotary arm are perpendicular to each other.

[0010] The beneficial effect of the above scheme is that when the rotary arm rotates clockwise, the lifting arm presses against the patient's lower jaw and lifts it, so as to prevent the patient's tongue root from falling back.

[0011] The above-mentioned device for preventing the tongue root from falling back after anesthesia also has the following characteristics: the one-way adjustment part includes a main shaft, a ratchet, a movable claw and a spring; the ratchet is sleeved on the main shaft; the two ends of the main shaft serve as two power ends, respectively pass through the inner side walls of the headrest body on both sides and extend to the outside of the headrest body and then are connected to the swing arm; the movable claw is arranged close to the ratchet, one end of the spring is connected to the movable claw, and the other end of the spring is connected to the inner side wall of the headrest body; when the spring is in a natural state, the movable claw abuts against the ratchet to limit the counterclockwise rotation of the ratchet; the recovery part is transmission-connected to the movable claw to drive the movable claw to separate from the ratchet and compress the spring.

[0012] The beneficial effect of the above scheme is that the ratchet and the movable pawl cooperate with each other, and when the ratchet rotates clockwise, the ratchet can rotate freely. When the ratchet rotates counterclockwise, the movable pawl is engaged with the ratchet and the ratchet cannot rotate.

[0013] The above-mentioned device for preventing the tongue root from falling back after anesthesia also has the following characteristics: the recovery part includes a traction rope, a winding drum and a torsion spring, one end of the winding drum is rotatably connected to the inner cavity side wall of one side of the headrest body, the other end of the winding drum passes through the inner cavity side wall on the other side of the headrest body, and extends to the outside of the headrest body, the torsion spring is arranged in the winding drum, one end of the torsion spring is connected to the side wall of one side of the headrest body, the other end of the torsion spring is connected to the inner side wall of the winding drum, one end of the traction rope is connected to the outer side wall of the winding drum, and the other end of the traction rope is connected to the movable claw through a guide wheel. When the winding drum is rotated, the movable claw can be driven to separate from the ratchet through the traction rope.

[0014] The beneficial effect of the above scheme is that the take-up drum is used to pull the traction rope to drive the movable claw to leave the ratchet wheel, so that the ratchet wheel can be rotated counterclockwise, so as to achieve the effect of rotating the swing arm counterclockwise.

[0015] The above-mentioned device for preventing the tongue root from falling back after anesthesia also has the following characteristics: the neck support assembly includes a base box and a supporting member, a telescopic part is provided in the base box, the upper end of the telescopic part can extend out of the base box, and the supporting member is provided at the upper end of the telescopic part.

[0016] The beneficial effect of the above scheme is that when the arm is raised to lift the patient's lower jaw, the patient's neck will be further suspended in the air, and the cooperation between the telescopic part and the supporting member can prevent the patient's neck from being excessively suspended in the air.

[0017] The above-mentioned device for preventing the tongue root from falling back after anesthesia of a patient also has the characteristic that the top surface of the supporting member is configured to be in an arc shape that fits the patient's neck.

[0018] The beneficial effect of the above solution is that the supporting member can always fit the patient's neck, thereby improving comfort.

[0019] In summary, the beneficial effects of this scheme are:

[0020] In the device for preventing the tongue root from falling back after anesthesia provided by the utility model, the mandibular lifting component is rotated to different angles to lift the mandibular of the patient to different angles, and the neck support component is used to support the neck of the patient with the mandibular lifted, so as to ensure that the airway of the patient remains unobstructed after anesthesia as much as possible. The device for preventing the tongue root from falling back after anesthesia provided by the utility model has the effect of assisting in lifting the mandibular of the anesthetized patient and preventing the tongue root from falling back.
