Description

Technical Field

[0001] The utility model relates to the field of medical nursing equipment, in particular to a dental pad with a negative pressure suction function. Background Technique

[0002] Clinically, patients undergoing general anesthesia or first aid often need to undergo tracheal intubation. During intubation, in order to prevent the patient from biting the tracheal tube, a dental pad must be placed between the upper and lower front teeth of the patient, and the tracheal tube and the dental pad must be properly fixed. At present, most use adhesive tape to fix the dental pad, and then fix the tracheal tube on one side of the dental pad. Moreover, the part of the dental pad in contact with the patient's face is made of hard plastic, which is extremely easy to cause pressure sores. In this way, when medical staff perform daily oral care on patients, it is neither convenient to remove the dental pad without moving the tracheal tube, nor can they perform oral care on the patient when the dental pad is placed in the patient's mouth. There is also a risk that the intubation will be bitten by the patient's teeth. And currently, the part of the dental pad extending into the mouth is relatively long, which limits the movement space of the tongue in the patient's mouth and causes discomfort to the patient. Among them, a medical multi-functional dental pad with the application number "CN202022164078.0", the structure of the utility model is simple and easy to use. By adjusting the distance between the upper dental plate and the lower dental plate, the intubation at the oral part of the patient can always be between the upper dental plate and the lower dental plate, preventing the patient from unconsciously biting the tracheal intubation. Openings and operation holes are respectively arranged on both sides of the mounting hole on the limit plate, which can facilitate medical staff to remove the dental pad for the patient to perform oral care without changing the patient's tracheal intubation. However, there are still certain deficiencies in the use of this dental pad: after a tongue cancer patient undergoes a flap operation, the tongue will be significantly swollen and the tongue movement will be restricted. After this dental pad is placed inside the patient's mouth, it can play a certain protective effect, but it cannot aspirate the secretions in the patient's oral cavity, and the structure of the limit plate is relatively large, so medical staff cannot observe the color of the flap, which makes it necessary to remove the dental pad for viewing. Content of the Utility Model

[0003] The purpose of the utility model is to provide a dental pad with a negative pressure suction function, so as to solve the problems put forward in the above background technique that after this dental pad is placed inside the patient's mouth, it can play a certain protective effect, but it cannot aspirate the secretions in the patient's oral cavity, and the structure of the limit plate is relatively large, so medical staff cannot observe the color of the flap, which makes it necessary to remove the dental pad for viewing.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A dental pad with a negative pressure suction function, including a support plate, an observation hole and a suction assembly;

[0005] Among them: a connecting ring is connected to the inner side of the support plate, an upper dental pad is fixedly connected to the surface of the connecting ring, and a lower dental pad is connected to the bottom of the connecting ring;

[0006] A viewing hole is penetrated through the middle of the surface of the support plate, and the connecting ring is connected to the inner wall of the viewing hole close to the oral cavity side;

One end of the suction pipe extends outside the connecting ring and is equipped with a liquid collection box. The surface of the liquid collection box is provided with a diversion hole, and one end of the suction pipe is connected to an external negative pressure device.

[0008] As a preferred solution of the present invention: The two sides of the support plate are respectively fixedly connected with a first connecting band and a second connecting band. One end of the first connecting band is connected with a fixing clip, and one end of the second connecting band is connected with a fixing seat. The fixing clip is engaged inside the fixing seat.

[0009] As a preferred solution of the present invention: The surface of the second connecting band is slidably connected with a tension adjusting buckle.

[0010] As a preferred solution of the present invention: Tooth biting grooves are provided on the surfaces of the upper dental pad and the lower dental pad, and the upper dental pad and the lower dental pad are made of silica gel material.

[0011] As a preferred solution of the present invention: A pipeline clip is installed on the surface of the suction pipe.

[0012] As a preferred solution of the present invention: Both the support plate and the connecting ring are made of transparent acrylic material.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) A viewing hole is penetrated through the middle of the surface of the support plate, and a connecting ring is installed on the inner wall of the viewing hole. The support plate and the connecting ring are made of transparent acrylic material, so that they have good light transmittance. When the patient wears the dental pad, the surgical site of the tongue flap can be observed through the viewing hole, which is convenient for medical staff to check the postoperative recovery situation. The doctor can diagnose without removing the dental pad, which is convenient for use;

[0015] (2) Through the provided suction assembly, a limit sleeve is slidably installed inside the viewing hole. A suction pipe is inserted through the inner wall of the limit sleeve. One end of the suction pipe is connected to an external negative pressure device, and the other end of the suction pipe is connected with a liquid collection box. A plurality of diversion holes are provided on the surface of the liquid collection box. The liquid collection box is placed inside the oral cavity. The oral secretion of the patient enters the liquid collection box through the diversion holes. Under the suction of the external negative pressure device, the oral liquid is sucked through the suction pipe into an external collection tank, preventing the oral liquid from flowing out of the patient's mouth. The suction pipe can be fixed on the surface of the clothing through the pipeline clip installed on the surface, preventing the suction pipe from sliding and causing traction to the liquid collection box.
