Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an oral breathing bite block capable of humidifying air and moisturizing lips. Background Art

[0002] Patients undergoing nasal cavity / transnasal surgery will have fillers stuffed in the nasal cavity for a period of time after the operation and cannot breathe through the nose, but can only breathe through an intubation in the mouth. The existing bite blocks are only the fixed endoscopic bite blocks applied to endoscopic examinations, without the function of moisturizing the lips and humidifying the air, and are only used for fixation during endoscopic examinations; during the process of oral breathing, due to the lack of humidification of the air by a nasal cavity-like structure, the lips and oral cavity will be uncomfortable due to dry air. Summary of the Invention

[0003] The purpose of the present invention is to provide an oral breathing bite block capable of humidifying air and moisturizing lips, which has a simple structure, low cost, and can relieve the oral comfort of patients after nasal cavity / transnasal surgery.

[0004] The oral breathing bite block capable of humidifying air and moisturizing lips provided by the present invention includes a bite block and a lip moisturizing sponge; wherein:

[0005] The bite block is divided into a lip moisturizing part and a tooth biting part connected front and back; when a person's teeth bite the tooth biting part, the lips can be attached to the lip moisturizing part;

[0006] A central air cavity is provided in the center of the bite block; on the side wall of the lip moisturizing part of the bite block, around the area of the central air cavity, a plurality of through holes penetrating the side wall of the lip moisturizing part are provided as moisture through holes, and external air can enter the area of the central air cavity through the moisture through holes;

[0007] The lip moisturizing sponge is sleeved on the lip moisturizing part and covers the moisture through holes;

[0008] The tooth biting part of the bite block is provided with a ventilation pore channel facing the oral cavity; the lip moisturizing part is provided with an insertion pore channel for inserting an oxygen supply tube.

[0009] In the present invention, oxygen can enter the central air cavity of the bite block from the insertion pore channel and enter the oral cavity through the ventilation pore channel of the tooth biting part.

[0010] In the present invention, there are two insertion pore channels in the lip moisturizing part, arranged left and right, and a C-shaped groove with a cross-section horizontally penetrating the orifices of the two insertion pore channels is provided on the outer side wall of the lip moisturizing part; the shape and size of the C-shaped groove and the insertion pore channels match the size of a medical nasal oxygen tube, the tube body of the nasal oxygen tube can be fixed by being clamped into the C-shaped groove, and two parallel nasal plug tubes for inserting into two nostrils are vertically arranged on the tube body of the nasal oxygen tube, and the nasal plug tubes can be respectively inserted into the two insertion pore channels.

[0011] In the present invention, the volume of the lip-moistening part of the bite block is larger than that of the tooth-biting part; in this way, when the teeth bite on the tooth-biting part, the lips can naturally fit on the lip-moistening part, ensuring the comfort of the patient during biting.

[0012] In the present invention, on the surface of the lip-moistening part, there is an air guide groove penetrating through the outer surface of the lip-moistening part from front to back, and at the same time, the air guide groove passes through several positions of moisture through holes; when the lip-moistening sponge fits on the surface of the lip-moistening part, air can sequentially enter the middle air cavity through the air guide groove and the moisture through holes, that is, a channel for air to enter can be formed.

[0013] In this way, it can not only increase the channels for the patient to breathe in and out, keep the breathing in and out unobstructed, but also provide an auxiliary breathing channel when the ventilation volume through the lip-moistening sponge decreases due to excessive water absorption by the lip-moistening sponge, ensuring that moisture can be introduced into the middle air cavity by external air.

[0014] In the present invention, a moisture-retaining sponge is laid in the area of the middle air cavity inside the lip-moistening part.

[0015] In this way, when water enters the middle air cavity through the moisture through holes due to excessive water volume or lip extrusion on the upper end surface of the lip-moistening part, it will be absorbed by the moisture-retaining sponge. This not only prevents excessive water from accumulating in the middle air cavity and being inhaled by the patient or flowing out from the corners of the mouth, but also can reduce the dripping amount, while ensuring the moisture supply inside the bite device.

[0016] In the present invention, moisture through holes are provided on the upper and lower end surfaces (the surfaces directly contacted by the upper and lower lips) of the lip-moistening part. Among them, the positions of the moisture through holes on the upper end surface and the lower end surface of the lip-moistening part are staggered in the vertical direction; the moisture-retaining sponge is provided with openings corresponding to the positions of the moisture through holes.

[0017] In this way, when the patient uses it in a sitting position, if the lip-moistening sponge has too much water, and if water droplets form in the moisture through holes on the upper end surface, they will drip onto the moisture-retaining sponge inside the lower end surface.

[0018] In the present invention, the tooth-biting part is sleeved with a soft medical tooth-biting silica gel sleeve that can cover the tooth-biting part; this makes it convenient to disassemble and replace after use at the tooth-biting part. At the same time, the soft material can improve the biting comfort, increase the biting friction, and prevent the bite device from falling off.

[0019] When the present invention is used, during the postoperative recovery process, the patient can only breathe through the mouth; the patient bites the tooth-biting part of the bite block with the teeth, and the lips fit around and cover the lip-moistening sponge of the lip-moistening part; the ventilation holes of the tooth-biting part face the patient's oral cavity, and the oxygen tube is inserted into the intubation hole of the lip-moistening part; oxygen enters the inside of the bite block through the oxygen tube, and then enters the patient's oral cavity through the ventilation holes; during the oxygen supply process, pure water can be dropped onto the lip-moistening sponge for moistening, and the lips are kept moist through the lip-moistening sponge. At the same time, because the patient breathes through the mouth, the moisture of the moist lip-moistening sponge is inhaled into the center of the lip-moistening part when the patient inhales, and the oxygen entering through the intubation hole carries the moisture into the patient's oral cavity to keep the patient's oral cavity moist. The detachable lip-moistening sponge and silicone sleeve can be used as disposable replaceable components, which is convenient for maintaining the hygiene of the bite device and can be used for a long time.

[0020] The structure of the present invention is simple, the cost is low, it is convenient for mass production, it can increase the humidity of the air inhaled through the mouth, keep the patient's oral cavity moist, and improve the comfort of the patient during the postoperative recovery period of nasal cavity / transnasal surgery.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Embodiment 1

[0031] The present invention includes a bite block 1, a lip-moistening sponge 2, and a tooth-biting silicone sleeve 3; a matching oxygen tube is selected as a nasal oxygen tube of a conventional double-nasal plug tube, that is, a nasal oxygen tube including two nasal plug tubes inserted into the nostrils. Among them:

[0032] The bite block 1 is made of hard medical silicone or medical plastic, and is divided into a lip-moistening part 4 and a tooth-biting part 5 connected front and back; the lip-moistening part 4 and the tooth-biting part 5 are designed in the shape of two cubes of different sizes butt-jointed integrally, and all sides of the cube are chamfered with large rounded chamfers, and the volume of the lip part is larger than that of the tooth-biting part; in this way, when the patient's teeth bite on the tooth-biting part 5, the lips can naturally fit on the lip-moistening part 4, ensuring the comfort of the lip fit when the patient bites.

[0033] The centers of both the lip-moistening part 4 and the tooth-biting part 5 are hollow, and are connected through to form a large central air cavity 6; on the side wall of the lip-moistening part 4 of the bite block 1, around the area of the central air cavity 6, a number of through holes penetrating the side wall of the lip-moistening part 4 are provided as moisture through holes 7, and external air can enter the area of the central air cavity 6 through the moisture through holes 7.

[0034] The lip-moistening sponge 2 is sleeved on the lip-moistening part 4 to cover the moisture through holes 7; as Figure 2 shown;

[0035] The tooth-biting part 5 of the bite block 1 is provided with a ventilation hole channel 8, and the lip-moistening part 4 is provided with an insertion hole channel 9 for inserting an oxygen supply tube.

[0036] There are two insertion hole channels 9 in the lip-moistening part 4, arranged left and right, and on the outer side wall of the lip-moistening part 4, there is a C-shaped groove 10 horizontally penetrating the orifices of the two insertion hole channels 9; the shape and size of the groove 10 and the insertion hole channel 9 match the size of a conventional medical nasal oxygen tube. Since the nasal oxygen tube is a soft hose, the tube body can be fixed by being deformed and snapped into the groove 10. Two parallel nasal plug tubes for inserting into two nostrils are vertically arranged on the tube body of the nasal oxygen tube, and the nasal plug tubes can be respectively inserted into the two insertion hole channels 9. As Figure 3 shown.

[0037] In this way, oxygen can enter the central air cavity of the lip-moistening part through the insertion hole channel, and enter the oral cavity through the ventilation hole channel of the tooth-biting part.

[0038] The tooth-biting silicone sleeve 3 can be sleeved on the tooth-biting part 5, so that after use of the tooth-biting part, it can be removed and replaced. At the same time, the soft material can improve the biting comfort, increase the biting friction, and prevent the occluder from falling off.

[0039] When the present invention is in use, during the postoperative recovery process, the patient can only breathe through the mouth; the patient bites the tooth-biting part of the bite block with the teeth, and the lips fit and wrap around the lip-moistening sponge of the lip-moistening part; the ventilation holes of the tooth-biting part face the patient's oral cavity, and the oxygen tube is inserted into the insertion hole of the lip-moistening part; oxygen enters the inside of the bite block through the oxygen tube and then enters the patient's oral cavity through the ventilation holes; during the oxygen supply process, pure water can be dropped onto the lip-moistening sponge for moistening, and the lip-moistening sponge is used to keep the lips moist. At the same time, due to breathing through the mouth, the moisture of the moist lip-moistening sponge is inhaled into the center of the lip-moistening part through the moisture through-holes during inhalation, and the oxygen entering through the insertion hole brings the moisture into the patient's oral cavity to keep the patient's oral cavity moist. The detachable lip-moistening sponge and silicone sleeve can be used as disposable replaceable components, which is convenient for maintaining the hygiene of the bite device and can be used for a long time. If the lip-moistening sponge becomes dry after a period of time, it only needs medical staff to directly drip water onto the external lip-moistening sponge through a dropper for water replenishment, which is convenient for operation.

[0040] Embodiment 2

[0041] The present invention includes a bite block 1, a lip-moistening sponge 2, and a tooth-biting silicone sleeve 3; a matching oxygen tube is selected as a conventional single tube; in this way, at the lip-moistening part 4, the insertion hole 9 is a single hole, and the oxygen tube is inserted into the insertion hole 9 in a direct insertion manner; a silicone sealing ring is provided in the insertion hole 9 to ensure the sealing of the oxygen tube insertion. As Figure 4 , Figure 5 shown.

[0042] The usage method is the same as that of Embodiment 1.

[0043] Embodiment 3

[0044] The present invention includes a bite block 1, a lip-moistening sponge 2, and a tooth-biting silicone sleeve 3; a matching oxygen tube is selected as a conventional single tube; the lip-moistening part 4 and the tooth-biting part 5 of the bite block 1 are detachable structures, the connecting part adopts an inverted buckle structure, and a two-shot injection molding method can be used, and only the connecting part adopts a harder material to ensure the firmness of the connection.

[0045] The moisture through-holes 7 are arranged on the upper, lower, left, and right four surfaces of the lip-moistening part 4, and the moisture through-holes 7 on the upper and lower surfaces can be arranged in a 3*3 rectangular array, and the moisture through-holes 7 on the left and right surfaces can be arranged in a 3*2 rectangular array; on the upper, lower, left, and right four end surfaces of the lip-moistening part 4, a plurality of parallel and concave air guide grooves 11 are provided, and each air guide groove 11 penetrates through three moisture through-holes 7 in the front-rear direction (i.e., the direction of oxygen delivery into the oral cavity), as Figure 7 shown; when the lip-moistening sponge 2 is attached to the surface of the lip-moistening part 4, a channel for air to enter can also be formed, as Figure 8As shown; the thickness of the lip moisturizing part 4 made of silicone can be set to 3 - 4 mm, and the depth of the air guiding groove 11 can be set to 1 - 2.5 mm, as long as it can ensure that air can enter smoothly without damaging the integrity of the lip moisturizing part 4; in this way, it can not only increase the breathing channels for the patient during inhalation and exhalation, keeping the inhalation and exhalation unobstructed, but also provide auxiliary breathing channels when the ventilation volume through the lip moisturizing sponge 2 decreases due to excessive water absorption by the lip moisturizing sponge 2, ensuring that moisture can be introduced into the middle air cavity 6 by external air.

[0046] In addition, before connecting the lip moisturizing part 4 and the tooth biting part 5, a layer of moisture - retaining sponge 12 is laid closely along the inner side wall in the middle air cavity 6 of the bite block 1, especially in the area inside the lip moisturizing part 4; the moisture - retaining sponge 12 is provided with openings corresponding to the positions of the moisture through - holes 7; then the lip moisturizing part 4 and the tooth biting part 5 are closed and connected; as Figure 6 shown.

[0047] At the same time, among the moisture through - holes 7 provided on the upper and lower end faces (the faces where the upper and lower lips directly contact) of the lip moisturizing part 4, the positions of the moisture through - holes 7 on the upper end face and the lower end face of the lip moisturizing part 4 are staggered in the vertical direction; as Figure 6 shown;

[0048] In this way, when water enters the middle air cavity 6 through the moisture through - hole 7 because the lip moisturizing sponge 2 on the upper end face of the lip moisturizing part 4 has too much water or is squeezed by the lips, it will be absorbed by the moisture - retaining sponge 12. This can not only prevent excessive water from accumulating in the middle air cavity 6 and being inhaled by the patient or flowing out from the corners of the mouth, but also reduce the amount of dripping water, while ensuring the supply of moisture inside the bite device. The staggered design of the moisture through - holes 7 on the upper and lower end faces means that when the patient is in a sitting position and the lip moisturizing sponge has too much water, if water droplets form in the moisture through - hole on the upper end face, they will drip onto the moisture - retaining sponge inside the lower end face, further ensuring the moisture inside the bite device.

[0049] The usage method is the same as that in Embodiment 1.

[0050] The structure of the present invention is simple, with low cost, convenient for mass production, capable of increasing the humidity of the inhaled air in the mouth, keeping the patient's oral cavity moist, and improving the comfort of patients during the postoperative recovery period of nasal cavity / trans - nasal surgery.
