Description

Technical Field

[0001] This utility model relates to the field of medical assistive devices, and in particular to a tracheal intubation fixation device that facilitates oral care. Background Technology

[0002] There are two existing methods for securing endotracheal tubes: one involves wrapping the tube with medical tape and attaching it to the patient's face, and the other uses a special fixator, which is secured to the back of the head with a strap around the patient's head. However, neither method is convenient for oral care. Each time oral care is needed, the medical tape must be removed or the fixator taken off. One healthcare worker holds the endotracheal tube while another uses a toothbrush to apply mouthwash or injects mouthwash into the patient's mouth through a tube. Simultaneously, the suction machine tube must be inserted into the patient's mouth to remove the used mouthwash. After cleaning, a nursing solution is sprayed into the patient's mouth to prevent bacterial growth. Finally, the endotracheal tube is secured again with medical tape or by inserting the fixator back into the patient's mouth. The nursing process is extremely inconvenient, time-consuming, laborious, and inefficient.

[0003] It is evident that the existing endotracheal intubation fixation devices described above still have inconveniences and shortcomings, and urgently need further improvement. Creating a new endotracheal intubation fixation device that facilitates oral care is indeed one of the important research and development topics at present. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tracheal intubation fixator that facilitates oral care, so that it does not require the use of medical tape for fixation, and does not need to be removed during oral care, making the care process convenient and quick, improving care efficiency. At the same time, it can automatically perform care through the timer function of the infusion pump and the negative pressure pump, thereby overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, this utility model provides a tracheal intubation fixator that facilitates oral care, including a base, a dental pad, and a fixation component; The base is semi-elliptical and ring-shaped, with an angle between its upper and lower surfaces, and is outwardly flared. The dental pad matches the shape of the base and is detachably connected to the upper and lower surfaces of the base. The fixing component is installed in the middle of the base for passing the endotracheal tube through the inside of the fixing component and fixing it in place; The base has a liquid supply connector fixedly connected to its outer surface for connecting to the liquid supply pump via an external pipeline. The base has cavities on both sides and a first channel in the middle of the base that connects the liquid supply connector to the cavities on both sides. The base has multiple spray holes on its inner surface that communicate with the cavities. Mouthwash or nursing solution is sprayed into the patient's mouth through the liquid supply pump, the liquid supply connector, the first channel, the cavity, and the spray holes for oral care. A suction connector is fixedly connected to the outer surface of the base for connecting to a negative pressure pump via an external pipeline. A suction tube is installed in the cavity on each side of the base. One end of the suction tube is sealed to the inner wall of the cavity, and the other end extends out of the base. A second channel is opened in the middle of the base to connect the suction connector and the suction tube. The mouthwash in the patient's mouth is sucked out through the suction tube, the second channel, the suction connector, and the negative pressure pump.

[0006] As an improvement of this utility model, the base is provided with partitions on both sides, which divide the cavity into an independent upper cavity, middle cavity and lower cavity. The spray holes on the inner surface of the base are arranged in three rows, which are connected to the upper cavity, middle cavity and lower cavity respectively. The upper cavity, middle cavity and lower cavity are each provided with an independent liquid inlet. A distribution valve is provided between the first channel and the cavity. The distribution valve is slidably fitted with the base. The distribution valve has a first inlet, a second inlet, a first outlet, a second outlet, and a third outlet that are interconnected. When the distribution valve slides to the lower position, the first inlet is connected to the first channel, the first outlet is connected to the upper cavity, and the third outlet is connected to the lower cavity; when the distribution valve slides to the upper position, the second inlet is connected to the first channel, and the second outlet is connected to the middle cavity.

[0007] Furthermore, the diameters of the upper and lower row nozzles are larger than those of the middle row nozzles.

[0008] Furthermore, the outer surface of the distribution valve extends beyond the base and is machined with several raised ridges.

[0009] Furthermore, the upper surface of the base and the upper tooth pad are provided with spray holes that extend to the upper cavity, and the lower surface of the base and the lower tooth pad are provided with spray holes that extend to the lower cavity.

[0010] Furthermore, the end of the suction tube is provided with a one-way valve and a filter cartridge.

[0011] Furthermore, two arc-shaped connecting plates are fixedly connected to the outer surface of the base. The sidewalls of the connecting plates are used to fit against the corners of the patient's mouth. The ends of the connecting plates are connected to a first strap. The first straps on both sides are fixedly connected to the back of the patient's head by buckles.

[0012] Furthermore, the fixing assembly includes a universal joint, a sleeve, a second strap, and a locking buckle; The base has a spherical groove in the middle, and the universal joint is also spherical and placed in the spherical groove. A circular hole with internal and external penetration is opened at the center of the universal joint. The sleeve passes through the circular hole and is fixedly connected to the universal joint. The part of the sleeve located on the outside of the mouth is provided with a second strap and a buckle. One end of the second strap is fixedly connected to the inner wall of the sleeve, and the other end wraps around the inside of the sleeve, then passes through the side wall of the sleeve and into the buckle. The latch is located outside the sleeve, and has a pressure plate, a pin, and a spring inside. It has a lever on the outside. The pressure plate is rotatably connected to the latch housing through the pin. The spring is fitted on the pin and presses the pressure plate tightly. The lever is fixedly connected to the pin and the pressure plate. The pressure plate is used to press and lock the second strap, and the lever is used to move the pressure plate to release the lock.

[0013] Furthermore, a panoramic lens and LED beads are provided on the inner surface of the base.

[0014] With this design, the present invention has at least the following advantages.

[0015] 1. This utility model provides a first channel, a cavity, a second channel, and a suction tube within the fixation base. With the connection of an external liquid supply pump and a negative pressure pump, oral care can be performed without removing the fixation, significantly improving the convenience of oral care, reducing personnel input, lowering the workload of medical staff, and improving nursing efficiency.

[0016] 2. This utility model achieves adjustable spraying mode by setting a manually controlled distribution valve. When cleaning the mouth, a large-diameter nozzle is selected, and the mouthwash is sprayed into the patient's mouth in the form of a jet. When performing oral care, a small-diameter nozzle is selected, and the care solution is sprayed into the patient's mouth in the form of a spray. It is convenient and flexible to use.

[0017] 3. This utility model can effectively fix the endotracheal tube through the fixing component, and while ensuring that the insertion depth remains unchanged, it allows for a certain amount of room for the angle of the endotracheal tube, thus avoiding pressure sores in the patient's mouth.

[0018] 4. The end of the suction tube is equipped with a one-way valve and a filter. The one-way valve can prevent the mouthwash remaining in the suction tube from flowing back into the patient's mouth, and the filter can prevent the suction tube opening from sticking to the patient's oral mucosa.

[0033] Please see Figures 1 to 5 This utility model provides a tracheal intubation fixation device that facilitates oral care, including a base 1, a dental pad 2, and a fixation component 3.

[0034] The base 1 is generally semi-elliptical in shape, with an angle between its upper and lower surfaces, thus opening outwards. The base 1 is made of PP material, which is hard and solid. The part near the center is solid, while the parts near the sides are hollow, meaning it has cavities inside.

[0035] The dental pad 2 matches the shape of the base 1 and is made of silicone material. It is detachably connected to the upper and lower surfaces of the base 1 by snap-fit ​​fixing for easy periodic replacement.

[0036] The base 1 has a liquid supply connector 4 fixedly connected to its outer surface near the center for connecting external pipelines to the liquid supply pump. A first channel 16 is opened inside the center of the base 1, which connects the liquid supply connector 4 to the cavities on the left and right sides, and a distribution valve 6 is provided between the first channel 16 and the cavity.

[0037] Please see Figures 6 to 8 The base 1 has partitions 14 installed in the cavities on both sides to divide the cavity into an independent upper cavity, middle cavity and lower cavity, and each cavity has its own independent liquid inlet.

[0038] The base 1 has a valve groove, and the distribution valve 6 is placed in the valve groove and can slide along the groove, that is, the distribution valve 6 and the base 1 form a sliding fit. The outer surface of the distribution valve 6 extends out of the base 1 and is machined with several protruding ridges to facilitate manual control of its operation. After the distribution valve 6 slides to the set position, it locks the position by friction with the side wall of the valve groove.

[0039] The distribution valve 6 is provided with a first inlet 18, a second inlet 19, a first outlet 20, a second outlet 21, and a third outlet 22 that are interconnected.

[0040] It should be noted that the distribution valves 6 on both sides are mirror images, with the first inlet 18 and the second inlet 19 facing the first channel 16, while the first outlet 20, the second outlet 21 and the third outlet 22 face the cavity. Figure 6 For ease of illustration, the two distribution valves 6 are adjusted to different positions. In actual use, the two distribution valves 6 are usually adjusted synchronously.

[0041] The distribution valve is designed to have two positions: upper and lower.

[0042] like Figure 7 As shown, when the distribution valve 6 slides to the lower position, the first inlet 18 is connected to the first channel 16, the first outlet 20 is connected to the upper cavity, the third outlet 22 is connected to the lower cavity, and the remaining inlets and outlets are closed by the valve groove sidewall.

[0043] like Figure 8 As described above, when the distribution valve 6 slides to the upper position, the second inlet 19 is connected to the first channel 16, the second outlet 21 is connected to the middle cavity, and the remaining inlets and outlets are closed by the valve groove sidewall.

[0044] The inner surface of the base 1 has three rows of spray holes 11, which are connected to the upper cavity, middle cavity, and lower cavity, respectively. The diameters of the upper and lower rows of spray holes 11 are larger than those of the middle row of spray holes 11. Furthermore, the upper surface of the base 1 and the upper side dental pad 2 have spray holes 11 that extend to the upper cavity, and the lower surface of the base 1 and the lower side dental pad 2 have spray holes that extend to the lower cavity.

[0045] When oral cleaning is required, adjust the dispensing valve 6 to the lower position. At this time, the mouthwash enters the upper and lower chambers through the liquid supply pump, liquid supply connector 4, first channel 16, and dispensing valve 6, and is sprayed out in the form of jet through the spray holes 11 of the upper and lower rows and the tooth pad 2.

[0046] When oral care is required, adjust the dispensing valve 6 to the upper position. At this time, the care solution enters the middle cavity through the supply pump, supply connector 4, first channel 16, and dispensing valve 6, and is sprayed out in the form of a spray through the middle exhaust nozzle 11.

[0047] It should be noted that the angles of the three rows of nozzles 11 on the inner wall of the base 1 all change with the shape of the base 1, allowing for comprehensive cleaning of all angles inside the patient's mouth. Furthermore, unlike traditional braces, the dental pad 2 only provides support for the teeth, rather than being tightly fitted onto them. The distance between the inner and outer walls of the dental pad 2 is greater than the thickness of the teeth. When the teeth bite down, they are positioned near the outer wall of the dental pad 2. After biting, a gap exists between the teeth and the inner wall of the dental pad 2, and the nozzles 11 are located in this gap, allowing for the spraying of mouthwash to clean the inner surfaces of the teeth.

[0048] Please see Figures 1 to 6 The base 1 has a liquid suction connector 5 fixedly connected to its outer surface near the middle, which is used to connect to the negative pressure pump through an external pipeline.

[0049] Each of the lower cavities on both sides of the base is equipped with a suction tube 7. One end of the suction tube 7 is sealed to the inner wall of the lower cavity, and the other end extends out of the base 1. A second channel 17 is opened in the middle of the base 1 to connect the suction connector 5 with the suction tubes 7 on both sides.

[0050] During oral cleaning, the used mouthwash is sucked out through the suction tube 7, the second channel 17, the suction connector 5, and the negative pressure pump.

[0051] It should be noted that the end of the suction tube 5 is equipped with a one-way valve and a filter cartridge 8. The one-way valve prevents mouthwash from flowing back into the patient's mouth, while the filter cartridge 8 prevents the tip of the suction tube 5 from completely adhering to the patient's oral mucosa. The suction tube 5 extends from the base 1 at both ends, behind the patient's molars. During oral cleaning, the patient's head needs to be adjusted to face to the side, so that the used mouthwash collects behind the molars, making it easy for the suction tube 5 to remove it. During oral cleaning, the supply pump and the negative pressure pump are activated simultaneously, spraying and suctioning the mouthwash to prevent excessive accumulation.

[0052] In addition, by installing timer switches on the liquid supply pump and the negative pressure pump, automatic oral cleaning or care can be achieved. After installing a metering switch on the liquid supply pump, pulsed metering multiple cleanings or metering care can be achieved. Oral cleaning requires the presence of a caregiver, while oral care can be performed automatically with timed and metered methods.

[0053] Please see Figures 1 to 5 Two arc-shaped connecting plates 9 are fixedly connected to the outer surface of the base 1, and the arc-shaped sidewalls fit against the corners of the patient's mouth. The ends of the connecting plates 9 are connected to the first straps 10, and the first straps 10 on both sides are fixedly connected to the back of the patient's head by buckles.

[0054] The inner surface of the base 1 is provided with a panoramic lens 12 and an LED bead 13. It can be connected to an external power supply and display via a cable, so that pressure sores can be observed in the patient's mouth without removing the endotracheal tube and fixator.

[0055] Please see Figure 5 and Figure 9 The fixing component 3 includes a universal joint 23, a sleeve 24, a second strap 25, and a buckle 26.

[0056] The base 1 has a spherical groove 15 in the middle, and the universal joint 23 is also spherical and placed in the spherical groove 15. The universal joint 23 has a through hole at the center, and the sleeve 24 passes through the hole and is fixedly connected to the universal joint 23. The part of the sleeve 24 located on the outside of the mouth is provided with a second strap 25 and a buckle 26.

[0057] One end of the second strap 25 is fixedly connected to the inner wall of the sleeve 24, and the other end wraps around the inside of the sleeve 24 and then passes through the side wall of the sleeve 24 and into the buckle 26.

[0058] Please see Figure 10 For ease of illustration, Figure 10 One side of the outer casing of latch 26 was removed.

[0059] The latch 26 is located outside the sleeve 24, and has a pressure plate 27, a pin 28 and a spring 29 inside, and a lever 30 on the outside.

[0060] The pressure plate 27 and the outer shell of the latch 26 are rotatably connected by a pin 28. The spring 29 is fitted on the pin 28 and presses the pressure plate 27 tightly. The lever 30 is fixedly connected to the pin 28 and the pressure plate 27.

[0061] In use, insert the endotracheal tube into the sleeve 24 and adjust the depth. After adjustment, turn the lever 30, and the pressure plate 27 will rise against the spring force of the spring 29, tightening the second strap 25. Then release the lever 30. At this time, the second strap 25 will tighten and lock the endotracheal tube. If adjustment is needed, turn the lever 30 again to release the pressure plate 27 from locking the second strap 25.

[0062] This utility model has a simple structure and is easy to use. It can perform oral cleaning and care without removing the fixator, and can realize automatic cleaning and care at fixed times and in fixed quantities, thereby improving the efficiency of cleaning and care, reducing the workload of medical staff, and is suitable for promotion.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
