Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a tongue lifting device for Zhuang medicine leech therapy for sublingual vein. Background Technology

[0002] Zhuang medicine leech therapy is a unique external treatment technique accumulated and summarized by the Zhuang people over thousands of years. It mainly utilizes leeches to bite and suck blood. When leeches bite, they not only draw out stagnant blood but also release various bioactive substances such as natural hirudin, fibrinolytic enzymes, and hyaluronidase. For stroke patients, whose blood is often in a hypercoagulable state and prone to thrombosis, leech sucking can reduce local blood stasis. The bioactive substances released by leeches can also improve blood rheology, which may help alleviate the condition and improve cerebral blood circulation. By acting on the sublingual veins, the leeches reduce local blood stasis and lower local venous pressure, allowing blood to flow more smoothly in the sublingual veins and reducing the risk of thrombosis.

[0003] However, stroke patients in the acute phase may experience impaired consciousness and decreased oral muscle control, making it difficult for them to cooperate in opening their mouths and lifting their tongues. This increases the difficulty of the procedure, making it hard to accurately place the leech near the sublingual vein. This can lead to improper leech attachment and affect the treatment effect. Therefore, when performing leech therapy, a tongue lifter is usually used to lift the patient's tongue to fully expose the sublingual vein. However, existing tongue lifters usually do not have oral cavity opening capabilities. During the procedure, medical staff may need to use an oral cavity opener to open the mouth and then use the tongue lifter to lift the tongue, increasing the complexity and difficulty of the operation. The combination of the two instruments may obstruct the full exposure of the sublingual vein. Furthermore, ordinary tongue lifters are held by medical staff and lack a reliable fixation method, making them easily displaced by involuntary movements of the patient's oral muscles. This is especially true for stroke patients, whose oral muscle control is weak. During the tongue lifting process, the tongue lifter frequently shifts, resulting in intermittent exposure of the sublingual vein, which is difficult to meet the requirements of continuous and stable vein exposure for leech therapy. Utility Model Content

[0004] This utility model provides a tongue-lifting device for Zhuang medicine leech therapy of sublingual veins to solve the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: it includes an oral cavity opener, a tongue lifter, and an angle adjustment mechanism. The oral cavity opener is used to secure itself to the upper and lower teeth to open the oral cavity and keep it in an open state. The two ends of the tongue lifter are rotatably connected to the oral cavity opener through connecting shafts. The angle adjustment mechanism is connected to the tongue lifter and is used to drive the tongue lifter to rotate at a certain angle, thereby lifting the tongue and exposing the sublingual vein. The angle adjustment mechanism has a one-way locking function to maintain the stability of the position of the tongue lifter after it is rotated.

[0006] Furthermore, the angle adjustment mechanism includes multiple squeezing teeth equidistantly arranged around the circumference of the rotating shaft and abutting teeth slidably connected inside the oral cavity opening frame. An elastic element is connected between the abutting teeth and the inner wall of the oral cavity opening frame. When the tongue lifting member flips and causes the inclined surface of the squeezing teeth to abut against the abutting teeth, the abutting teeth compress the elastic element. When the tongue lifting member stops flipping, the elastic element pushes the abutting teeth to insert between two adjacent squeezing teeth to achieve one-way locking of the tongue lifting member.

[0007] Furthermore, it also includes an unlocking component for releasing the angle lock of the lifting tongue component. The two ends of the unlocking component are respectively connected to two abutting teeth. The angle lock is released by pulling the abutting teeth out of the two adjacent pressing teeth through the unlocking component.

[0008] Furthermore, the outer wall of the oral cavity opening frame is provided with a receiving groove that is compatible with the unlocking component.

[0009] Furthermore, the oral cavity expander includes an upper support portion and a lower support portion integrally formed and connected to the upper support portion, and both the upper support portion and the lower support portion are provided with grooves for teeth to be inserted.

[0010] Furthermore, the outer surfaces of the oral cavity opening frame and the tongue lifting component are both made of flexible material.

[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0012] In this invention, the oral cavity opener is used to hold the patient's upper and lower teeth in place, keeping the patient's mouth open. Then, by flipping the tongue lifter, the tongue is lifted upwards from below to a certain position, fully exposing the sublingual veins for easy leech adsorption. The angle adjustment mechanism allows for flexible adjustment of the tongue lifter's angle and position while simultaneously locking it in one direction to prevent it from reversing or shifting due to involuntary movements of the patient's oral muscles or other external forces. Furthermore, it eliminates the need for medical personnel to constantly apply additional force to maintain the tongue lifter's position, making it more convenient and simple to use.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] This utility model provides a tongue-lifting device for sublingual vein leech therapy, including an oral cavity opener 1 for securing to the upper and lower teeth to open and maintain the oral cavity. The oral cavity opener 1 includes an upper support 11 and a lower support 12 integrally formed and connected to the upper support 11. Both the upper support 11 and the lower support 12 have grooves 13 for teeth to be inserted. In use, the patient's mouth is first opened using instruments such as mouth openers, and then the oral cavity opener 1 is placed into the patient's mouth, so that the patient's upper and lower teeth are respectively inserted into the grooves 13. At this time, the mouth openers are removed, and the patient's mouth remains open. The oral cavity opener 1 can be made of medical-grade plastic or metal with a certain degree of hardness to prevent the patient's upper and lower teeth from being pulled apart. When the jaw is strained, the oral cavity opening frame 1 deforms. A tongue lifting component 2 is rotatably connected to the lower support 12 via a connecting shaft 21. After the oral cavity is opened, the position of the tongue lifting component 2 is flipped to lift the tongue upward from below the patient's tongue, thus fully exposing the sublingual vein for leech adsorption. In order to facilitate the adjustment of the angle of the tongue lifting component 2 to suit the tongue condition of different patients, the tongue lifting component 2 is also connected to an angle adjustment mechanism for rotating the tongue lifting component 2 at a certain angle to lift the tongue and expose the sublingual vein. In addition, in order to avoid medical staff having to apply force to the tongue lifting component 2 to maintain its position, the angle adjustment mechanism also has a one-way locking function to maintain the stability of the position of the tongue lifting component 2 after it is flipped, so as to make it more convenient to perform leech adsorption treatment and reduce the operating intensity of medical staff.

[0025] Specifically, the angle adjustment mechanism includes multiple squeezing teeth 3 equidistantly arranged around the circumference of the rotating shaft and abutting teeth 31 slidably connected inside the oral cavity opening frame 1. When the tongue lifting member 2 flips, it drives the connecting shaft 21 and the squeezing teeth 3 to rotate. At this time, the inclined surface on the squeezing tooth 3 will abut against the inclined surface on the abutting tooth 31. An elastic element 32, such as a spring, is provided between the abutting tooth 31 and the inner wall of the oral cavity opening frame 1. When the abutting tooth 31 is squeezed by the squeezing tooth 3, it will compress the elastic element 32 and move into the interior of the oral cavity opening frame 1. When the squeezing tooth 3 does not squeeze the abutting tooth 31, the elastic force of the elastic element 32 will push the abutting tooth 31 to reset, so that the abutting tooth 31 is inserted between two adjacent squeezing teeth 3 to achieve one-way locking of the tongue lifting member 2. It can keep the patient's tongue in a certain raised state according to the actual use of the patient, and will not flip over randomly. At the same time, it does not require medical staff to constantly apply force to the tongue lifting member 2 to maintain its stability, which is more convenient.

[0026] Preferably, in order to facilitate lowering the tongue after treatment, an unlocking member 4 is also included for unlocking the flipping angle of the tongue lifting member 2. The two ends of the unlocking member 4 are respectively connected to two abutting teeth 31. When the unlocking member 4 is pulled to cause the abutting teeth 31 to compress the elastic member 32, the abutting teeth 31 disengage from the two adjacent squeezing teeth 3. At this time, the tongue lifting member 2 can be flipped in the opposite direction to unlock.

[0027] Preferably, a receiving groove 41 is also provided on the outer wall of the oral cavity expander 1. The receiving groove 41 is adapted to the unlocking member 4. That is, when the unlocking member 4 is located in the receiving groove 41, the unlocking member 4 will not protrude from the outside of the oral cavity expander 1. In this way, when the oral cavity expander 1 is located in the patient's oral cavity, the oral cavity expander 1 can be released from the patient's oral cavity tissues, and the patient will not feel uncomfortable due to the protruding unlocking member 4 contacting the patient's oral cavity tissues.

[0028] Preferably, in order to improve the comfort of the oral cavity expander when the patient's mouth is expanded, the outer surfaces of the oral cavity expander 1 and the tongue lifter 2 are both made of flexible material, such as medical silicone. The texture of flexible medical silicone is closer to human tissue, and the foreign body sensation is relatively weak after it is placed in the mouth. Unlike hard materials, it will not scratch or puncture the oral mucosa, gums and other tissues during the patient's oral activities. The patient can adapt more quickly during use, thereby improving the overall comfort and acceptance.

[0029] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
