Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an adjustable medical bite device. Background Art

[0002] Patients need to use a mouthpiece when undergoing gastroscopy. The function of the mouthpiece is that the patient bites the mouthpiece to facilitate the entry of the endoscope into the oral cavity. Because some patients undergoing endoscopic surgery are under general anesthesia, their breathing will be suppressed, and medical equipment such as anesthesia gas cannula will be needed to assist the patient's breathing during the operation. However, the current mouthpiece design has a mismatch between the size of the anesthesia gas cannula and the size of the mouthpiece, and the gas cannula is difficult to pass through the mouthpiece. If the gas cannula is forcibly inserted into the mouthpiece of the mismatched size, the mouthpiece may easily squeeze the airbag of the gas cannula, causing surgical risks and pain and discomfort to the patient. Utility Model Content

[0003] The utility model provides an adjustable medical mouthpiece, which can overcome certain defects of the prior art.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions, which include:

[0005] The mouthpiece body is tubular and has a first cavity formed inside along the length direction for cooperating with a gastroscope;

[0006] A baffle is arranged at one end of the mouthpiece body, an upper limit strip and a lower limit strip are respectively arranged at the upper edge and the lower edge of the baffle, a first groove is formed between the upper limit strip and the baffle, a second groove is formed between the lower limit strip and the baffle, and a first opening connected to the first cavity is also arranged on the baffle;

[0007] The slide of the frame structure includes an upper frame bar, a left frame bar, a lower frame bar and a right frame bar which are connected in sequence end to end, the upper frame bar and the lower frame bar can be respectively inserted into the first groove and the second groove; a first through hole for the air tube to pass through is formed between the left frame bar and the left edge of the baffle, and a second through hole for the air tube to pass through is formed between the right frame bar and the right edge of the baffle; a tongue depressor is arranged at the lower part of the other end of the bite device body.

[0008] Through the arrangement of the first cavity, baffle, upper limit strip, lower limit strip, first groove, second groove, first cavity, slide, second through hole, upper frame strip, left frame strip, lower frame strip and right frame strip in the utility model, when in use, let the patient bite the mouthpiece first, and then according to the size of the air cannula, slide the slide and fine-tune the position of the mouthpiece to change the size of the first through hole and the second through hole until the air cannula can pass through the first through hole or the second through hole. The adjustable size of the special hole for air cannula in the mouthpiece improves the flexibility of the mouthpiece in matching air cannulas of different sizes, thereby effectively reducing the problem of air cannula airbag being squeezed and ruptured due to the mismatch between the size of the air cannula and the size of the mouthpiece.

[0009] In the utility model, a tooth ring is integrally formed outside the bite device body, and the tooth ring, the bite device body and the baffle plate together form an annular groove.

[0010] Through the arrangement of the latch ring and the annular groove in the utility model, when the patient bites the mouthpiece, the patient's upper and lower front teeth are in the annular groove. Since the patient is in an anesthetized state, the patient's tongue may push the mouthpiece out without consciousness, and the latch ring on the mouthpiece can press against the inner wall of the teeth, thereby better preventing the mouthpiece from being spit out of the patient's mouth, and there is no need for medical staff to keep a close eye on the state of the mouthpiece.

[0011] Furthermore, in the prior art, in order to prevent the mouthpiece from being spit out from the patient's mouth, an elastic band is usually installed on the mouthpiece, but the present invention does not need to install an elastic band. Compared with the prior art, the present invention can avoid the problem of pressure sores on the patient caused by the elastic band, and the tooth ring is pressed against the patient's teeth, which can effectively reduce the situation of the patient spitting out the mouthpiece.

[0012] In the utility model, one end of the tongue depressor away from the mouthpiece body is bent downward.

[0013] By setting the downwardly curved tongue depressor in the utility model, the downwardly curved tongue depressor can fit the tongue root of the patient, which better prevents the patient's tongue from blocking the gastroscope when the gastroscope enters the patient's mouth, thereby enabling the gastroscope to better enter the digestive tract.

[0014] In the utility model, the baffle plate and the sliding sheet have the same curvature.

[0015] By arranging the baffle plate and the slide plate with the same curvature in the utility model, the curved baffle plate and the slide plate can better fit the oral skin of the patient.

[0016] In the utility model, the mouthpiece body and the baffle are integrally formed.

[0017] The bite device body and the baffle plate formed in one piece in the utility model can improve the structural strength of the bite device.

[0018] In the utility model, a first auxiliary limiting strip for cooperating with the first groove and a second auxiliary limiting strip for cooperating with the second groove are respectively arranged at the upper frame strip and the lower frame strip.

[0019] Through the provision of the first auxiliary limiting strip and the second auxiliary limiting strip in the utility model, the first auxiliary limiting strip and the second auxiliary limiting strip can respectively cooperate with the first groove and the second groove to further limit the upper frame strip and the lower frame strip respectively.

[0020] In the utility model, the mouthpiece body is in an elliptical tubular shape, which can increase the contact area between the patient's teeth and the annular groove so that the patient can bite the mouthpiece better.

[0021] In the utility model, both the left frame bar and the right frame bar may be provided with hollow holes, which can cooperate with the elastic band to further prevent the mouthpiece from being spit out from the patient's mouth. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0026] Example 1

[0027] like Figure 1-3 As shown, this embodiment provides an adjustable medical bite device, comprising:

[0028] The mouthpiece body is tubular and has a first cavity 101 formed inside along the length direction for cooperating with a gastroscope;

[0029] A baffle 102 is provided at one end of the mouthpiece body, and an upper limit bar 105 and a lower limit bar 106 are respectively provided at the upper edge and the lower edge of the baffle 102, a first groove 203 is formed between the upper limit bar 105 and the baffle 102, and a second groove 204 is formed between the lower limit bar 106 and the baffle 102, and a first opening communicating with the first cavity 101 is also provided on the baffle 102;

[0030] The slide 107 of the frame structure includes an upper frame bar 107A, a left frame bar 107B, a lower frame bar 107C and a right frame bar 107D which are connected in sequence end to end, the upper frame bar 107A and the lower frame bar 107C can be respectively inserted into the first groove 203 and the second groove 204; a first through hole 109 for the air tube to pass through is formed between the left frame bar 107B and the left edge of the baffle 102, and a second through hole 110 for the air tube to pass through is formed between the right frame bar 107D and the right edge of the baffle 102; a tongue depressor 104 is arranged at the lower part of the other end of the mouthpiece body.

[0031] Through the arrangement of the first cavity 101, the baffle 102, the upper limit strip 105, the lower limit strip 106, the first groove 203, the second groove 204, the first cavity 101, the slide 107, the second through hole 110, the upper frame strip 107A, the left frame strip 107B, the lower frame strip 107C and the right frame strip 107D in this embodiment, when in use, let the patient bite the mouthpiece first, and then according to the size of the air cannula, slide the slide and fine-tune the position of the mouthpiece to change the size of the first through hole and the second through hole until the air cannula can pass through the first through hole or the second through hole. The adjustable size of the special hole for the air cannula of the mouthpiece improves the flexibility of the mouthpiece in matching air cannulas of different sizes, thereby effectively reducing the problem of the air cannula airbag being squeezed and ruptured due to the mismatch between the size of the air cannula and the size of the mouthpiece.

[0032] Specifically, for example, Figure 1 As shown, if you want to insert the air cannula into the patient's mouth through the first through hole, slide the slide clockwise and fine-tune the mouthpiece body counterclockwise to make the first through hole larger enough to pass the air cannula.

[0033] In this embodiment, a tooth ring 103 is integrally formed outside the bite device body, and the tooth ring 103, the bite device body and the baffle 102 together form an annular groove.

[0034] Through the provision of the tooth ring 103 and the annular groove in this embodiment, when the patient bites the mouthpiece, the patient's upper and lower front teeth are in the annular groove. Since the patient is in an anesthetized state, the patient's tongue may push the mouthpiece out without consciousness, and the tooth ring on the mouthpiece can press against the inner wall of the teeth, thereby better preventing the mouthpiece from being spit out of the patient's mouth, and medical staff do not need to keep a close eye on the state of the mouthpiece.

[0035] Furthermore, in the prior art, in order to prevent the mouthpiece from being spit out from the patient's mouth, an elastic band is usually installed on the mouthpiece, but the elastic band does not need to be installed in the present embodiment. Compared with the prior art, the present embodiment can avoid the problem of pressure sores on the patient caused by the elastic band, and the tooth ring is pressed against the patient's teeth, which can effectively reduce the situation of the patient spitting out the mouthpiece.

[0036] In this embodiment, one end of the tongue depressor 104 away from the mouthpiece body is bent downward.

[0037] By setting the downwardly curved tongue depressor 104 in this embodiment, the downwardly curved tongue depressor can fit the patient's tongue root, which better prevents the patient's tongue from blocking the gastroscope when the gastroscope enters the patient's mouth, thereby allowing the gastroscope to better enter the digestive tract.

[0038] It is worth noting that during the operation, if there is no tongue depressor on the mouthpiece, the patient's tongue will be squeezed in the mouth, which will affect the patient's ventilation and easily cause hypoxemia in the patient, causing harm to the patient. Coupled with the effect of anesthesia on breathing, the patient is more likely to suffer from hypoxemia.

[0039] In this embodiment, the baffle 102 and the sliding sheet 107 have the same curvature.

[0040] By disposing the baffle plate 102 and the slide sheet 107 with the same curvature in this embodiment, the curved baffle plate 102 and the slide sheet 107 can better fit the oral skin of the patient.

[0041] In this embodiment, the mouthpiece body and the baffle 102 are integrally formed.

[0042] The integrally formed mouthpiece body and baffle 102 in this embodiment can improve the structural strength of the mouthpiece.

[0043] In this embodiment, a first auxiliary limiting strip 201 for cooperating with the first groove 203 and a second auxiliary limiting strip 202 for cooperating with the second groove 204 are respectively provided at the upper frame strip 107A and the lower frame strip 107C.

[0044] By disposing the first auxiliary limiting strip 201 and the second auxiliary limiting strip 202 in this embodiment, the first auxiliary limiting strip 201 and the second auxiliary limiting strip 202 can respectively cooperate with the first groove and the second groove to further limit the upper frame strip and the lower frame strip respectively.

[0045] In this embodiment, the mouthpiece body is an elliptical tube, which can increase the contact area between the patient's teeth and the annular groove so that the patient can bite the mouthpiece better.

[0046] In this embodiment, both the left frame bar 107B and the right frame bar 107D may be provided with hollow holes 108, which can cooperate with the elastic band to further prevent the mouthpiece from being spit out from the patient's mouth.

[0047] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

[0048] The above is a schematic description of the present invention and its implementation methods, which is not restrictive. The embodiments shown are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the present invention, they should all fall within the protection scope of the present invention.
