Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tracheal intubation, in particular to a movable bite pad and a tracheal intubation using the movable bite pad. Background Art
[0002] The main process of existing tracheal intubation includes inserting the catheter into the trachea through the mouth, then removing the guide wire, inserting the catheter into the glottis for a distance, and connecting the other end to the ventilator, further placing a dental pad between the upper and lower incisors in the mouth, and then inflating the air bag on the tracheal tube to fix the position of the tracheal tube in the trachea. In the existing tracheal intubation process, the dental pad and the tracheal intubation catheter are two separate devices. Therefore, it is necessary to use tape to bind and fix the catheter and the dental pad together, and stick them to the face to ensure the relative position of the catheter and the dental pad is fixed, and the relative position of the whole composed of the two is fixed on the head.
[0003] The main function of the dental pad is to prevent the teeth from biting the tracheal tube and affecting ventilation, and to fix the tube and prevent the tube from shifting in the mouth. However, the problem is that since both the tube and the dental pad are inserted through the mouth, considering the outer diameter of the tube, the size of the dental pad, the size of the patient's mouth, loose teeth, etc., placing the tracheal tube and the dental pad into the mouth together not only increases the difficulty, but also easily causes potential dangers to the patient's teeth, such as tooth loss, etc. This poses a great safety hazard to patients under anesthesia and is contrary to the safety requirements of the operation. In addition, using tape to fix the tube and the dental pad and their overall position on the face also has certain safety hazards. The tape is easily affected by secretions such as sweat and loses its stickiness, thus falling off and losing its fixing effect.
[0004] Therefore, it is necessary to adopt a new method to better fix the position of the catheter and the dental pad, and reduce the number of devices placed into the oral cavity, so as to protect the patient and further improve the safety of the operation. Utility Model Content

DETAILED DESCRIPTION
[0023] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
[0024] It should be noted that, unless otherwise defined, the technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0025] Embodiment 1 of a tracheal intubation of the utility model, as Figure 1 As shown, it includes a catheter 1 and a bite block 2. The catheter 1 is provided with an air bag 3 and an inflation tube 4 connected to the air bag. The catheter is guided by a guide wire 5 during insertion. The structure of the catheter and the guide wire belong to the prior art, and the specific structures of the two are not described in detail in this embodiment. The bite block 2 includes a bite block body, such as Figure 2 As shown, two ear plates 6 are arranged opposite to each other on the outer side of the mouthpiece body, and the two ear plates divide the mouthpiece body into an insertion section 8 and an external leakage section 9 along its length direction. The insertion section 8 is used to be inserted into the oral cavity, and the external leakage section 9 is the part that leaks out of the oral cavity when in use. Each ear plate 6 is connected to a strap (not shown in the figure) for fixing the mouthpiece body to the patient's head.
[0026] Specifically, each ear plate 6 is provided with a connection hole 7, and the bandage can be an elastic bandage, in which case one end of the bandage passes through a connection hole and is connected to the corresponding ear plate, and the other end passes through another connection hole and is connected to the corresponding ear plate. When in use, the bandage is elastically sleeved on the patient's head to fix the dental pad. There can also be two bandages, in which case the bandage can be an elastic bandage or an ordinary bandage without elasticity. In this case, one end of one bandage passes through a connection hole and is connected to the corresponding ear plate, and one end of the other bandage passes through another connection hole and is connected to the corresponding ear plate. When in use, the two bandages go around the patient's head and are connected together to fix the dental pad. Compared with the prior art using adhesive tape, the problem of the adhesive tape falling off due to sweating on the patient's face can be avoided.
[0027] The dental pad body has a hollow channel 10 for the catheter 1 to be movably worn. The movably worn means that the catheter is inserted into the hollow channel of the dental pad body, and the dental pad body can slide freely along the outer wall of the catheter. In the present embodiment, the external leakage section 9 on the dental pad body includes a fixed arc plate 11 and a movable arc plate 12, and a fixed structure is provided between the fixed arc plate and the movable arc plate, and the external leakage section can be fixedly clamped on the outer side of the catheter through the fixed structure. The movable arc plate and the fixed arc plate are separately arranged. In the present embodiment, the dental pad body except the movable arc plate can be integrally injection molded, and the movable arc plate can be injection molded separately. In the present embodiment, the fixed structure includes a clamp (shown in the figure) mounted on the outer sides of the two, and the clamp is a prior art, and its specific structure is not described in detail in the present embodiment. In other embodiments, the clamp may not be used, and the fixed structure may include an adhesive tape or a binding wrapped around the outer sides of the two. Through the fixing structure, the movable arc plate and the fixed arc plate are fixedly clamped on the outer wall surface of the catheter, so that the fixation between the tooth pad and the catheter is achieved.
[0028] When in use, the catheter is inserted into the hollow channel of the dental pad body, and the catheter is inserted into the patient's trachea with the help of a guide wire. When the catheter is inserted into place, the dental pad can slide along the catheter, and when the catheter is inserted into place, the dental pad is also moved to a suitable position in the oral cavity. At this time, the position of the dental pad can also be manually adjusted, the guide wire is pulled out, and the dental pad is fixed to the outer wall of the catheter through a fixing structure. The dental pad and the catheter are fixed to the patient's head as a whole by a bandage. The catheter is fixed in the patient's trachea by inflating the airbag. In this embodiment, the dental pad and the catheter are installed together, and the volume installed in the oral cavity is only the volume of the dental pad. Compared with the prior art in which the two are attached together and bundled and installed in the patient's oral cavity, the volume of the device in the oral cavity is reduced, the patient is protected, the operation is convenient, and the use is convenient.
[0029] Embodiment 2 of a tracheal intubation of the utility model, as Figure 3As shown, the only difference from the first embodiment is that the fixing structure on the tooth pad body is different. In this embodiment, the fixing structure includes a first protrusion 13 arranged on the fixed arc plate 11, and also includes a second protrusion 14 arranged on the movable arc plate 12, and the second protrusion is arranged corresponding to the first protrusion. A plug hole 15 is arranged on the first protrusion, and a plug column 16 for plugging and connecting with the plug hole is arranged on the second protrusion. The plug holes and the plug columns are arranged one by one. In this embodiment, the number of the plug holes and the plug columns are three. In other embodiments, the number of the plug holes and the plug columns can be adjusted according to actual needs. In order to ensure a stable connection between the plug column and the plug hole, an annular limiting protrusion is arranged on the plug column. When the plug column is inserted into the plug hole, the annular limiting protrusion is forced to pass through the plug hole and cooperates with the first protrusion limit stop to prevent the second protrusion from disengaging. In order to achieve a fixing effect between the tooth pad and the catheter, anti-slip patterns are arranged on the inner wall surface of the fixed arc plate and the inner wall surface of the movable arc plate. In other embodiments, anti-slip grooves may be provided only on the inner wall surface of the fixed arc-shaped plate or the inner wall surface of the movable arc-shaped plate.
[0030] Embodiment 3 of a tracheal intubation of the utility model, as Figure 4 and 5 As shown, the difference from the first embodiment is that the fixing structure on the tooth pad body is different. In this embodiment, one side of the movable arc plate 12 is connected to one side of the fixed arc plate 11 through a flexible connection portion 18, so that the movable arc plate 12 can be opened or closed around the flexible connection portion 18. In this embodiment, the movable arc plate 12 and the fixed arc plate 11 are integrally injection molded, and the connection portion between the two is a weak portion, and the thickness is relatively thin to form a flexible connection portion 18. In this embodiment, the fixing structure includes a first protrusion 13 arranged on the fixed arc plate 11, and also includes a second protrusion 14 arranged on the movable arc plate 12, and the second protrusion is arranged corresponding to the first protrusion. A plug hole 15 is arranged on the first protrusion, and a plug column 16 for plugging and connecting with the plug hole is arranged on the second protrusion. In this embodiment, the number of the first protrusions is three and is arranged at intervals along the length direction of the tooth pad, and correspondingly, the number of the second protrusions is also three and is arranged one-to-one with the first protrusion. In other embodiments, the number of the first protrusion and the second protrusion can be adjusted according to actual needs. In order to ensure a stable connection between the plug post and the socket, an annular limiting protrusion 17 is provided on the plug post. Figure 5 As shown, the plug post is inserted into the insertion hole, and the annular limiting protrusion is forced to pass through the insertion hole and cooperates with the first protrusion to prevent the second protrusion from being disengaged. In order to achieve the fixing effect between the tooth pad and the catheter, anti-slip grooves are provided on the inner wall surface of the fixed arc plate and the inner wall surface of the movable arc plate. In other embodiments, anti-slip grooves can also be provided only on the inner wall surface of the fixed arc plate or the inner wall surface of the movable arc plate.
