The invention provides an integrated saliva suction mouth gag, which comprises a saliva suction pipe and a mouth gag 3, wherein the saliva suction pipe comprises a water outlet pipe 1 and a flexible pipe 2.
Wherein the flexible pipe 2 is a pipeline which can be deformed obviously under the action of external force load. The flexible pipe 2 can be bent at any angle and is not easy to block.
The mouth gag 3 is provided with a built-in flow passage, and a water inlet 301 of the built-in flow passage of the mouth gag 3 is used for sucking up liquid such as saliva generally accumulated in the mouth of a patient and a medical solution ejected from a medical instrument.
One end of the water outlet pipe 1 is connected with a water outlet of a built-in flow passage of the mouth gag 3, the other end of the water outlet pipe is connected with a dental medical equipment main body (namely saliva suction equipment and a strong suction pipe on a dental chair), and the flexible pipe 2 is connected in series on the water outlet pipe 1 and is close to the connecting end of the mouth gag 3.
The present case provides a pair of integral type saliva suction mouth gag, according to patient's oral cavity hydrops position, through carrying out the buckling of certain angle to 2 parts of flexible tube on outlet pipe 1, make mouth gag 3's water inlet 301 aim at the hydrops imbibition, liquid passes through mouth gag 3's built-in runner and arranges to the dentistry medical equipment main part from outlet pipe 1 in. This design is convenient for adjust and is inhaled the saliva angle, and it is comfortable and convenient to use, both can provide opening auxiliary stay, can inhale the saliva again.
In the preferred embodiment, the flexible tube 2 is a corrugated tube, which can be bent at any angle, and is convenient for clinical use. Because the whole corrugated pipe is made of soft plastic materials, the special structural property of the corrugated pipe can realize bending without blocking water flow. Of course, the flexible pipe 2 may also be a rubber hose or a flexible pipe of other material and shape, and may be specifically selected adaptively according to practical application, which is not described herein again.
In the specific embodiment, the water outlet pipe 1 is made of soft plastic. The mouth gag 3 is made of soft plastic, so that the mouth gag has better mouth use feeling, can effectively support teeth and is not easy to deform.
In order to improve the sealing performance and the connection reliability, the saliva suction pipe and the mouth gag 3 can be arranged into an integrated structure, and the production cost is low. In particular, the mouth gag can be made of elastic materials, combines the functions of a saliva suction pipe and a mouth gag, integrates the functions of saliva suction and auxiliary opening, and is more comfortable and convenient to use.
In one embodiment, as shown in fig. 1, the mouth gag 3 is in a semi-circular configuration and the water inlet 301 is provided as a sunken protrusion. The sinking type protruding part has a certain sinking depth and can easily extend into the lower part of the liquid level of the oral cavity.
In particular, the number of the sinking projections may be multiple, that is, multiple water inlets 301, and the number of the sinking projections is 2 in fig. 1.
In order to be placed in the oral cavity of a patient conveniently, the semicircular arc surface of the mouth gag 3 is provided with the occlusal surface 304 of the chewing gum, the whole radian design enables the mouth gag to be more attached to the surface of the teeth after the mouth is opened, and the use comfort level is improved. The chew may prevent the mouth gag 3 from scratching the walls of the patient's mouth cavity. The occlusal surface 304 is provided with a plurality of anti-slip lines to prevent the biting rubber from moving.
Furthermore, two sides of the semicircular cambered surface of the mouth gag 3 are provided with blocking ribs 303 which are used for fitting two sides of teeth, facilitating occlusion and preventing the movement of the chewing gum.
When the mouth gag 3 is placed in the mouth, the occlusal surface 304 is supported by the upper jaw or the lower jaw, both side surfaces of the occlusal surface 304, i.e., the barrier ribs 303 are attached to the inner sides of the teeth, and the tip end thereof is supported by the lower jaw or the upper jaw, thereby supporting the mouth of the patient to maintain the mouth in an open state.
In order to make the chew have a certain strength to support the teeth and to assist the opening, a reinforcing rib 302 is provided inside the mouth gag 3.
As shown in figure 4, when the water inlet 301 and the water outlet of the mouth gag 3 are arranged on two adjacent surfaces, preferably, when the axis of the water inlet 301 and the axis of the water outlet form an included angle of 90 degrees or an included angle close to 90 degrees, the mouth gag 3 is favorably placed in the oral cavity, and the angle of the water inlet is conveniently adjusted to suck liquid.
In order to facilitate the liquid suction at the left and right sides of the oral cavity, two water inlets 301 corresponding to the left and right sides of the oral cavity are arranged on the mouth gag 3.
In order to improve the fluidity of liquid suction and reduce the liquid suction resistance, the built-in flow passage of the mouth gag 3 extending in the direction close to the water inlet 301 is a divergent flow passage.
Particularly, the water inlet 301 of the mouth gag 3 has a certain opening angle, and simultaneously adopts a sinking design, so that the mouth gag can easily probe into the lower part of the oral cavity liquid level and has high saliva absorbing efficiency.
In addition, the present embodiment also provides a dental medical device comprising the above integrated saliva suction opener.
Since the dental medical device has the integrated saliva suction mouth gag, the dental medical device has the beneficial effects brought by the integrated saliva suction mouth gag, please refer to the above contents, and the details are not repeated herein.
The working process of the scheme is specifically as follows: the switch of the saliva suction device of the dental medical device is turned on, the mouth gag 3 is slowly put into the mouth of the patient, the patient bites the mouth gag by the upper jaw and the lower jaw or hangs the mouth gag at the lower jaw of the patient, the position of the water inlet 301 can be continuously and manually adjusted in the treatment process to extend into the liquid accumulated in the oral cavity, and the saliva is discharged into the saliva suction device through the water outlet pipe 1 connected with the mouth gag 3.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts.
