Description

Squeezing device

The invention relates to a mouthpiece, in particular to a mouthpiece having a double layer material.

The mouthpiece is used by anesthetized or oxygenated patients to support the upper and lower teeth to prevent the patient from involuntarily biting the tracheal intubation during anesthesia or first aid, causing obstruction of the tracheal intubation, affecting the patient's breathing and possibly causing suffocation. Therefore, it is necessary to use a bite device made of a hard material to prevent the patient from biting the tracheal intubation, but when the patient's anesthesia is just retreating or just waking up, the foreign body in the mouth may feel uncomfortable and quite repelled, or it may be because The pain is generated and the bite is bitten hard, but the bite device made of hard material may cause the patient's teeth to break. In order to solve such a problem, for example, "Mouth Guard for Use with a Diagnostic Instrument" of U.S. Patent No. 4,640,273 discloses a mouthpiece having a hard inner layer and a flexible soft outer layer, thereby preventing the teeth from biting a hard material. And the problem of breakage.

However, the above-mentioned mouthpiece only covers the flexible soft material on the outer layer, and the patient may push the mouthpiece with the tongue and contact the inside of the mouthpiece under the uncomfortable or just waking panic condition. The layer causes the patient's tongue and oral mucosa to be scratched due to the scratching of the hard material inside the mouthpiece. The infection of the endometrium may cause many unforeseen major complications for the critically ill patients, which may affect the patient. The time of recovery is more likely to aggravate the patient's condition. In addition, because the inner and outer layers are made of different materials, they are bonded to each other by means of a connecting agent. When the patient bites the mouthpiece hard, the flexible outer layer of the biting device is easy to be externally driven. The effect of falling off, causing the risk of use. Moreover, the ring design close to the lip is also prone to cause a lot of lip pressure sore problems due to prolonged compression of the patient's lips, which in turn causes infection problems.

The main object of the present invention is to solve the problem that the tongue and the oral mucosa are scratched due to the hard material of the mouthpiece.

Another object of the present invention is to solve the problem that the inner and outer double-layer mouthpieces are likely to cause the biting device of the inner and outer layers to separate and fall off due to the excessive bite force.

In order to achieve the above object, the present invention provides a mouthpiece that is fixedly placed in a human oral cavity with an endotracheal tube, the mouthpiece comprising a rigid tube member and an elastic coating covering the surface of the rigid tube member. The rigid pipe member comprises a pipe body, a passage disposed in the pipe body, a tongue portion disposed on one side of the pipe body, and a nip portion adjacent to the tongue tongue portion, the tongue portion having a first through hole perpendicular to an axial direction of the passage, and a stopper connected to a side of the engaging portion away from the tongue portion; the elastic covering member penetrates the at least one first through hole and includes There is a covering body, a positioning portion covering the channel adjacent to the surface of the pressing tongue portion, and a resilient blocking piece corresponding to the stopper.

As can be seen from the above description, the present invention has the following features:

1. The rigid tube member in the shape of the tube is matched with the design of the tongue portion to avoid the problem that the mouthpiece is easily pushed out by the patient.

Second, the use of the covering body and the positioning portion to effectively prevent the patient's tongue from contacting the rigid tubular member and causing scratches, resulting in damage to the tongue and the inside of the oral cavity.

The cover body and the positioning portion are reinforced by the at least one first through hole to prevent the elastic coating from being covered by the elastic covering member. The piece is detached from the rigid pipe.

The detailed description and technical content of the present invention will now be described as follows:

Please refer to FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4A and FIG. 4B , the present invention is a mouthpiece which is fixedly placed in a tracheal intubation 1 . In the human oral cavity (not shown), the mouthpiece includes a rigid tubular member 10 and an elastic covering member 20 covering the surface of the rigid tubular member 10. The rigid pipe member 10 includes a pipe body 11, a passage 12 disposed in the pipe body 11, a tongue portion 13 disposed on one side of the pipe body 11, and a nip portion adjacent to the tongue portion 13 14. A stopper 15 connected to a side of the nip portion 14 away from the tongue portion 13 and an extension portion 16 connected to a side of the stopper 15 away from the nip portion 14, the tongue portion 13 having at least one The first through hole 131 is perpendicular to the axial direction of the passage 12. The channel 12 can be used for twitching or corresponding operation by a nursing staff or a physician; the tongue portion 13 is used to penetrate into the oral cavity of the human body, so that the tongue can easily push the mouthpiece and the mouthpiece is detached. The occlusal portion 14 provides the patient's teeth Performing a bite to maintain the patient's mouth open, and the endotracheal tube 1 can be inserted into the human oral cavity for corresponding anesthesia, first aid or supply of oxygen; the stopper 15 is disposed outside the human body; the extension 16 Then, a caregiver or a physician is provided to place or remove the mouthpiece in the human mouth, and the extension 16 can also be used by a caregiver or a physician to perform corresponding tape adhesion and fixation.

The elastic covering member 20 extends through the at least one first through hole 131 and includes a covering body 21, a positioning portion 22 covering the surface of the tongue and groove portion 13 adjacent to the channel 12, and a corresponding covering layer The elastic blocking piece 23 on the stopper 15 extends from the center outward and is correspondingly disposed on the outside of the lip, thereby preventing the mouthpiece from sliding into the human oral cavity, the elastic covering member The cover 20 is formed in the at least one first through hole 131, and the cover body 21 and the positioning portion 22 are reinforced and fixedly connected to the at least one first through hole 131 to prevent the elastic cover member 20 from being detached from the hard Pipe fitting 10. In addition, in order to enhance the fixing effect, the elastic covering member 20 may also be coated on the inner surface of the passage 12, thereby completely covering the rigid tubular member 10 to reduce the elastic covering member 20 and the rigid tubular member. 10's probability of separation.

It is further explained that the stopper 15 includes a first notch region 151 corresponding to the first notch region 151 and a second notch region 231 to be firmly supported by the tracheal cannula 1. The tongue portion 13 extends from a position of the engaging portion 14 away from the stopper 15 and has a tapered arc portion 131 adjacent to one side of the passage 12 and a side away from the passage 12 The pressing section 132 can be used as a means for pressing the tongue to protect the endotracheal tube 1 from the tongue, and the tapered arc section 131 is relatively smooth to avoid pressing the oral mucosa and causing the oral cavity. The mucosa is broken and there is a problem of infection or ulceration.

Referring to FIG. 5 again, the stopper 15 has at least one second through hole 152 parallel to the axial direction of the passage 12 for covering the elastic covering member 20. The elastic covering member 20 reinforces the fixing ability with the rigid tubular member 10 by passing through the first through hole 133 and the second through hole 152. Therefore, even if the patient is overpowered, the bite at the occlusion portion 14 is broken. The elastic covering member 20 can still be stably fixed on the rigid tubular member 10 by the connection with the first through hole 133 and the second through hole 152, thereby avoiding the elastic package. The problem of the falling off of the cover 20 and the rigid tubular member 10.

As shown in FIG. 6 , the elastic flap 23 of the elastic covering member 20 has a plurality of protruding portions 232 adjacent to one side surface of the engaging portion 14 , and the protruding portions 232 can be used. It is avoided that the elastic flap 23 causes a problem of pressure ulcers on the lips due to prolonged contact with the outside of the patient's lips. In addition, the elastic flap 23 can be made of a transparent material, so that the caregiver can directly observe the color of the patient's lips, thereby judging the patient's physical condition.

Referring to FIG. 4B, in order to further alleviate the influence of the patient's tooth bite force, the occlusal portion 14 has two gullets 141 respectively corresponding to the positions of the upper row of teeth and the lower row of teeth of the body cavity. The elastic covering member 20 has two tooth biting projections 24 corresponding to the slots 141, respectively. In other words, the thickness of the tooth biting projection 24 is thicker than that of other regions of the elastic covering member 20, and on the other hand, the patient can provide better elasticity when the tooth biting projection 24 is engaged. The cushioning is better, and the thicker the bite protrusion 24 can reduce the chance of the elastic covering member 20 being bitten by the patient. On the other hand, the tooth biting protrusion 24 is fixed with the tooth groove 141. In a manner, the fixed positioning capability of the elastic covering member 20 and the rigid tubular member 10 can be further enhanced.

In summary, the present invention has the following features:

1. The rigid tube member in the shape of the tube is matched with the design of the tongue portion to avoid the problem that the mouthpiece is easily pushed out by the patient.

Second, the use of the covering body and the positioning portion to effectively prevent the patient's tongue from contacting the rigid tubular member and causing scratches, resulting in damage to the tongue and the inside of the oral cavity.

3. By the formation of the first notch region and the second notch region, a positioning space for stably relying on the tracheal intubation and entering and exiting the human oral cavity is provided.

4. The first through hole and the second through hole cooperate with the elastic covering member to strengthen the fixed connection between the elastic covering member and the rigid tubular member, even if the elastic covering member is stuck due to the patient's bite force. If it is too large and breaks, the elastic covering member can still be fixedly connected to the rigid pipe member.

5. Cooperating with the arrangement of the tooth groove and the tooth biting bump, on the one hand, providing a better cushioning force when engaging, and reducing the possibility that the elastic covering member is bitten by a patient, and the rigid pipe fitting is also provided on the other hand. The elastic covering member preferably has a fixed positioning capability.

Therefore, the present invention is highly progressive and conforms to the requirements of the invention patent application, and the application is filed according to law, and the praying office grants the patent as soon as possible.

The present invention has been described in detail above, but the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the scope of the invention. That is, the equivalent changes and modifications made by the scope of the present application should remain within the scope of the patent of the present invention.
