Description

Technical Field

[0001] The present invention belongs to the field of tracheal intubation fixation, and particularly relates to a detachable tracheal intubation fixation device. Background Art

[0002] In modern clinical medicine, tracheal intubation is an important means of establishing an artificial airway and is widely used in the rescue and treatment of patients such as general anesthesia, respiratory failure, and cardiac and respiratory arrest. The core function of tracheal intubation is to ensure the patency of the patient's airway and maintain effective ventilation and oxygenation. However, due to factors such as the patient's consciousness state, body position change, and swallowing reflex, the tracheal intubation is extremely prone to displacement, prolapse, etc. during use, which will not only lead to serious consequences such as ventilation failure and hypoxia, but may also cause complications such as airway injury and pulmonary infection. Therefore, reliable fixation of tracheal intubation is a key link to ensure the treatment effect and patient safety.

[0003] Traditional tracheal intubation fixation mainly relies on winding and fixing with tape or gauze band. Its basic principle is to paste the tape on the patient's face or head to physically bind the intubation to the facial skin or head and neck. However, this fixation method has obvious technical defects: First, the fixation effect depends on the operator's experience, and the stickiness of the tape is greatly affected by the patient's sweat and oral secretions, and it is easy to loosen. Second, the process of tape sticking and removal may cause damage to the patient's facial skin, especially for critically ill patients who are bedridden for a long time, which is likely to cause pressure sores or skin allergies. Third, repeated sticking and tearing are required during fixation, and the operation time is long. Especially in emergency situations, it is difficult to quickly complete the fixation or adjustment. When the patient needs to perform oral care, sputum suction and other operations, the tape needs to be completely removed, and then fixed again after the operation is completed, which not only increases the workload of medical staff, but also increases the risk of intubation displacement. Fourth, the fixation device needs to be completely removed during oral care, which is cumbersome and may cause the risk of intubation displacement. Summary of the Invention

[0004] The purpose of the present invention is to provide a detachable tracheal intubation fixation device to solve the problems of difficult and time-consuming disassembly, assembly, fixation or adjustment of the traditional fixation device, large workload and unsatisfactory work efficiency as mentioned in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A detachable tracheal intubation fixation device, comprising a main body and a connection mechanism; the main body includes a bite block, a through hole is arranged in the bite block, fixing plates are arranged on both sides of the bite block, straps are arranged at the rear ends of the two fixing plates, a head pad is movably connected between the two straps, and pressing blocks are movably arranged in the bite block at the top and bottom of the through hole; the connection mechanism includes connection seats arranged on both sides of the bite block, a clamping rod is arranged at the front end of the fixing plate, a clamping groove is arranged on the connection seat, a tapered block is arranged in the connection seat at the top of the clamping groove through a spring, and a pull rod is arranged at the top of the tapered block and penetrates through the connection seat.

[0007] Preferably, an opening is arranged on the bite block at one side of the top of the through hole.

[0008] Preferably, an eccentric wheel is movably arranged in the bite block at the bottom of the pressing block, a swing arm is arranged at the input end of the eccentric wheel, and the eccentric wheel is located at the bottom of the through hole.

[0009] Preferably, the clamping groove is adapted to the clamping rod.

[0010] Preferably, connecting rods are arranged at both ends of the head pad, and magic tapes are arranged on the outer surface of the strap.

[0011] Preferably, the tracheal intubation fixation device further includes a pressure adjustment mechanism, the pressure adjustment mechanism includes a slider slidably arranged on the strap, and an arc-shaped plate is arranged on the slider.

[0012] Preferably, two convex blocks are arranged on the outer side of the strap, and an elastic band is arranged between the two convex blocks.

[0013] Preferably, an inclined plate is arranged at the front end of the fixing plate, and buffer pads are arranged on the inner side surfaces of the inclined plate and the fixing plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Through the cooperation of the clamping rod and the clamping groove in the connection mechanism of the present invention, combined with the locking structure of the tapered block driven by the spring, the quick connection and separation of the bite block and the fixing plate are realized. When the clamping rod is inserted into the clamping groove, the locking mechanism is automatically pushed open by the inclined surface of the tapered block, and the spring is reset to achieve locking after in place, without manual adjustment; when disassembling, only need to pull the pull rod to release the locking, and the whole process can be completed with one hand operation, which significantly improves the working efficiency of medical staff, and is especially suitable for quick fixation and rescue operations in emergency situations.

[0025] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0026] Secondly, as used herein, "an embodiment" or "embodiments" refer to specific features, structures, or characteristics that may be included in at least one implementation of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0027] As shown in the Figure 1 to Figure 6 accompanying

[0028] Embodiment 1: This embodiment provides a detachable tracheal intubation fixation device, including a main body 1 and a connection mechanism 2; the main body 1 includes a mouthguard 101, a through hole 106 is provided in the mouthguard 101, fixing plates 102 are provided on both sides of the mouthguard 101, straps 103 are provided at the rear ends of the two fixing plates 102, a head pad 104 is movably connected between the two straps 103, and a pressing block 1061 is movably arranged in the mouthguard 101 at the top and bottom of the through hole 106; the connection mechanism 2 includes connection seats 205 arranged on both sides of the mouthguard 101, a clamping rod 203 is provided at the front end of the fixing plate 102, a clamping groove 206 is provided on the connection seat 205, a tapered block 204 is arranged in the connection seat 205 at the top of the clamping groove 206 through a spring 207, a pull rod 208 is arranged at the top of the tapered block 204 and penetrates through the connection seat 205, and the mouthguard 101 is made of, including but not limited to, hard plastic, resin, or ceramic.

[0029] When the patient needs to be intubated, the head pad 104 is placed under the patient's head, and then the patient is asked to bite the bite pad 101. After adjusting the length of the strap 103 according to the size of the patient's head contour, the strap 103 is connected to the head pad 104 and the fixing plate 102 is pulled so that the strap 103 and the fixing plate 102 are in contact with the patient's head until the clamping rod 203 is clamped into the clamping groove 206. During the process, the clamping rod 203 will contact the conical block 204 in advance, and an oblique thrust will be generated to it through the inclined surface of the conical block 204 to push it upward, thereby opening the clamping groove 206. When the clamping rod 203 completely enters the clamping groove 206, the spring 207 will push the conical block 204 downward due to the disappearance of resistance, so as to limit the position of the clamping rod 203 and prevent it from leaving the clamping groove 206, thereby completing the quick connection between the bite pad 101 and the fixing plate 102. After completion, the pull rod 208 is pulled to pull the conical block 204 upward to open the clamping groove 206. Open, at this time, the clamping rod 203 will automatically disengage from the clamping slot 206, completing the rapid separation of the fixing plate 102 and the tooth pad 101, and then the pipeline is passed through the through hole 106 for intubation. During the process, the tooth pad 101 can be used as a bite device to prevent the patient from biting the pipeline. After the intubation is completed, the patient bites the tooth pad 101 to temporarily limit it, and then uses the pressure block 1061 to squeeze and limit the position of the pipeline, thereby fixing the tooth pad 101 on the pipeline, and then pulls the two fixing plates 102 at the same time, relying on the above steps to clamp the clamping rod 203 into the clamping slot 206 to complete the connection between the fixing plate 102 and the tooth pad 101, and complete the complete limitation of the tooth pad 101 and the pipeline to avoid the occurrence of pipeline deviation and loosening. When the pipeline needs to be taken out, it is only necessary to pull the pull rod 208 to separate the tooth pad 101 from the fixing plate 102 to complete the limitation of the pipeline position. The disassembly and assembly are quick, and the patient's head does not need to move, which is convenient to use.

[0030] Specifically, an opening is provided on the tooth pad 101 at one side of the top of the through hole 106 .

[0031] Medical staff can insert the pipeline into the through hole 106 through the opening, and use the elastic contraction of the pipeline itself during the insertion process to make it expand and self-limit after being inserted into the through hole 106, so as to avoid easy separation from the tooth pad 101 without external limitation.

[0032] Specifically, an eccentric wheel 1062 is movably disposed in the tooth pad 101 at the bottom of the pressing block 1061 , a swing arm 1063 is disposed at the input end of the eccentric wheel 1062 , and the eccentric wheel 1062 is located at the bottom of the through hole 106 .

[0033] When the medical staff moves the swing arm 1063, the eccentric wheel 1062 is driven to rotate, thereby pushing the pressing block 1061 to move up and down, so that the pressing block 1061 can be fixed on the tooth pad 101 after it contacts the pipeline.

[0034] Specifically, the latching slot 206 is matched with the latching rod 203 .

[0035] The locking rod 203 is locked into the card slot 206 and cannot move, but can only rotate.

[0036] Specifically, connecting rods 107 are provided at both ends of the head pad 104, and a magic tape 108 is provided on the outer surface of the strap 103.

[0037] When the strap 103 needs to be connected to the head pad 104, the rear end of the strap 103 is bypassed around the connecting rod 107. The magic tape 108 is divided into a sub-tape and a mother-tape. After the rear end of the strap 103 is bypassed around the connecting rod 107 and fits against its side surface, the connection between the strap 103 and the head pad 104 can be completed by the interlocking connection of the magic tape.

[0038] Embodiment 2: This embodiment provides a detachable tracheal intubation fixation device, including a main body 1 and a connection mechanism 2; the main body 1 includes a dental pad 101, a through hole 106 is provided in the dental pad 101, fixing plates 102 are provided on both sides of the dental pad 101, straps 103 are provided at the rear ends of the two fixing plates 102, a head pad 104 is movably connected between the two straps 103, and a pressing block 1061 is movably provided in the dental pad 101 at the top and bottom of the through hole 106; the connection mechanism 2 includes connection seats 205 provided on both sides of the dental pad 101, a locking rod 203 is provided at the front end of the fixing plate 102, a card slot 206 is provided on the connection seat 205, a tapered block 204 is provided in the connection seat 205 at the top of the card slot 206 through a spring 207, and a pull rod 208 is provided at the top of the tapered block 204 and penetrates through the connection seat 205.

[0039] When the patient needs to be intubated, the head pad 104 is placed under the patient's head, and then the patient is asked to bite the bite pad 101. After adjusting the length of the strap 103 according to the size of the patient's head contour, the strap 103 is connected to the head pad 104 and the fixing plate 102 is pulled so that the strap 103 and the fixing plate 102 are in contact with the patient's head until the clamping rod 203 is clamped into the clamping groove 206. During the process, the clamping rod 203 will contact the conical block 204 in advance, and an oblique thrust will be generated to it through the inclined surface of the conical block 204 to push it upward, thereby opening the clamping groove 206. When the clamping rod 203 completely enters the clamping groove 206, the spring 207 will push the conical block 204 downward due to the disappearance of resistance, so as to limit the position of the clamping rod 203 and prevent it from leaving the clamping groove 206, thereby completing the quick connection between the bite pad 101 and the fixing plate 102. After completion, the pull rod 208 is pulled to pull the conical block 204 upward to open the clamping groove 206. Open, at this time, the clamping rod 203 will automatically disengage from the clamping slot 206, completing the rapid separation of the fixing plate 102 and the tooth pad 101, and then the pipeline is passed through the through hole 106 for intubation. During the process, the tooth pad 101 can be used as a bite device to prevent the patient from biting the pipeline. After the intubation is completed, the patient bites the tooth pad 101 to temporarily limit it, and then uses the pressure block 1061 to squeeze and limit the position of the pipeline, thereby fixing the tooth pad 101 on the pipeline, and then pulls the two fixing plates 102 at the same time, relying on the above steps to clamp the clamping rod 203 into the clamping slot 206 to complete the connection between the fixing plate 102 and the tooth pad 101, and complete the complete limitation of the tooth pad 101 and the pipeline to avoid the occurrence of pipeline deviation and loosening. When the pipeline needs to be taken out, it is only necessary to pull the pull rod 208 to separate the tooth pad 101 from the fixing plate 102 to complete the limitation of the pipeline position. The disassembly and assembly are quick, and the patient's head does not need to move, which is convenient to use.

[0040] Specifically, an opening is provided on the tooth pad 101 at one side of the top of the through hole 106 .

[0041] Medical staff can insert the pipeline into the through hole 106 through the opening, and use the elastic contraction of the pipeline itself during the insertion process to make it expand and self-limit after being inserted into the through hole 106, so as to avoid easy separation from the tooth pad 101 without external limitation.

[0042] Specifically, an eccentric wheel 1062 is movably disposed in the tooth pad 101 at the bottom of the pressing block 1061 , a swing arm 1063 is disposed at the input end of the eccentric wheel 1062 , and the eccentric wheel 1062 is located at the bottom of the through hole 106 .

[0043] When the medical staff moves the swing arm 1063, the eccentric wheel 1062 is driven to rotate, thereby pushing the pressing block 1061 to move up and down, so that the pressing block 1061 can be fixed on the tooth pad 101 after it contacts the pipeline.

[0044] Specifically, the latching slot 206 is matched with the latching rod 203 .

[0045] The clamping rod 203 is inserted into the clamping groove 206 and cannot move, but can only rotate.

[0046] Specifically, connecting rods 107 are provided at both ends of the headrest 104, and a magic tape 108 is provided on the outer surface of the strap 103.

[0047] When the strap 103 needs to be connected to the headrest 104, the rear end of the strap 103 is bypassed around the connecting rod 107. The magic tape 108 is divided into a sub-tape and a mother-tape. After the rear end of the strap 103 bypasses the connecting rod 107 and fits against its side surface, the connection between the strap 103 and the headrest 104 can be completed by using the interlocking connection of the magic tape.

[0048] Specifically, the endotracheal tube fixing device further includes a pressure adjusting mechanism 3. The pressure adjusting mechanism 3 includes a slider 302 slidably disposed on the strap 103, and an arc-shaped plate 301 is provided on the slider 302.

[0049] When medical staff fix the device on the patient's head through the strap 103, the arc-shaped plate 301 will be located between the strap 103 and the patient's skin. The arc-shaped setting of the arc-shaped plate 301 will push up the strap 103 to form an arc-shaped gap, so that the skin here will not come into contact with the strap 103. After working for a certain period of time, push the slider 302 to make the arc-shaped plate 301 move on the strap 103 to avoid discomfort caused by long-term compression of a certain area of the skin.

[0050] Specifically, two convex blocks 201 are provided on the outer side of the strap 103, and an elastic band 202 is provided between the two convex blocks 201.

[0051] When a person pulls the fixing plate 102 to connect it to the dental pad 101 or adjusts the position of the arc-shaped plate 301, the elastic band 202 will synchronously stretch and deform according to the change in the pulling force. Thus, when connecting the fixing plate 102 to the dental pad 101 or moving the arc-shaped plate 301, the pressure exerted by the strap 103 on the skin is adjusted, so as to ensure that the pressure of the strap 103 on the skin remains within a comfortable range without secondary adjustment of the length of the strap 103, improving efficiency and facilitating the use by personnel.

[0052] Specifically, an inclined plate 303 is provided at the front end of the fixing plate 102, and buffer pads 105 are provided on both the inclined plate 303 and the inner surface of the fixing plate 102.

[0053] When the arc-shaped plate 301 moves close to the fixed plate 102, it will lift the rear end of the fixed plate 102, causing it to swing around the clamping rod 203 as the axis, so as to expose the cheek skin at the fixed plate 102, facilitating nursing and avoiding compression damage. When the rear end of the fixed plate 102 tilts up, the inclined plate 303 at the front end of the fixed plate 102 will swing downward until it contacts the patient's skin, thereby ensuring stability. The buffer pad 105 is made of a comfortable and breathable material, such as a porous silica gel pad, to improve the comfort of the patient.
