Description

Technical Field

[0001] The utility model belongs to the technical field of medical supplies and relates to a monitoring structure of a dental pad for surgery. Background Art

[0002] For patients with endotracheal intubation inserted through the mouth, in order to prevent the patient's teeth from biting and closing the endotracheal tube, a dental pad is usually used. The dental pad has a through hole for operations such as sputum suction.

[0003] For existing dental pads, for example, a Chinese patent document discloses an endotracheal intubation fixing dental pad [Patent No.: 202121530323.3; Application Publication No.: CN215608529U], which includes a dental pad body. An outer ring retaining ring of the dental pad is arranged at the end of the dental pad body. Below the outer ring retaining ring of the dental pad and sleeved on the outer wall of the dental pad body is an inner ring retaining ring of the dental pad. An endotracheal intubation positioning sleeve is embedded on the outer wall of the dental pad body on the inner ring retaining ring of the dental pad. An opening groove is arranged on the side wall of the endotracheal intubation positioning sleeve along the Z axis.

[0004] This kind of dental pad structure can keep the patient's mouth open, prevent the endotracheal tube from being bitten and closed, and also prevent the upper and lower rows of the patient's teeth from biting each other. However, when the patient is undergoing surgery, there are situations such as masseter spasm in the patient, and there is a problem of excessive biting force between the upper and lower rows of teeth. Prolonged biting of the dental pad with excessive biting force will cause damage to the patient's teeth. Summary of the Invention

[0005] The purpose of the utility model is to address the above problems existing in the prior art and propose a monitoring structure of a dental pad for surgery, and the technical problem to be solved is how to enable the dental pad to sense the biting force of the teeth and avoid tooth damage to the patient during surgery.

[0006] The purpose of the utility model can be achieved by the following technical solutions: A monitoring structure of a dental pad for surgery, the dental pad includes a body made of silicone or rubber material, and the body has a through hole for a catheter to pass through. It is characterized in that the monitoring structure includes a strain gauge and a wire. The strain gauge is embedded in the body, one end of the wire extends into the body and is electrically connected to the strain gauge, and the other end extends out of the body for detachably electrically connecting to a circuit board.

[0007] During use, insert the main body into the patient's mouth, and the patient's teeth press against the main body, specifically against the position where the strain gauge is located on the main body. It is connected to the circuit board through a wire. The main body, strain gauge, and wire are disposable items with low cost. The circuit board is located outside the main body and is detachably electrically connected to the outer end of the wire, enabling the circuit board to be reused multiple times. The circuit board has structures such as a single-chip microcomputer and an alarm. The circuit board collects the resistance change of the strain gauge, processes it through the single-chip microcomputer, and converts it into an electrical signal to be transmitted to the alarm to emit an alarm sound. When the patient's teeth bite tightly on the main body and the biting force exceeds the set value, since the main body is made of silica gel or rubber material, the main body will undergo a certain deformation, causing the strain gauge to be squeezed and deformed to a certain extent. The resistance value of the strain gauge will change to a certain degree. When the resistance value change collected by the circuit board is too large, the alarm emits an alarm sound, reminding the medical staff that the patient's biting force is too large, enabling the medical staff to take timely measures to avoid damage to the patient's teeth. Moreover, since the main body is made of silica gel or rubber material, compared with the main body made of plastic material, it can reduce damage to the patient's teeth.

[0008] In the monitoring structure of a dental pad for surgery described above, a recessed installation groove is provided on the outer sidewall of the main body. A wire passing hole communicating the installation groove and the outside is provided in the sidewall of the main body. The wire passing hole is arranged along the axial direction of the main body. The main body includes a cover plate. The strain gauge is adhesively fixed to the bottom of the installation groove and is embedded in the installation groove through the cover plate for sealing. The wire passes through the wire passing hole. This structure enables the main body and the cover plate of the main body to be injection-molded separately, allowing the strain gauge to be installed in the main body after the main body is injection-molded, preventing the strain gauge from being damaged. By sealing the strain gauge with the cover plate, the patient will not directly contact the strain gauge, improving the induction accuracy of the strain gauge. The wire passing hole is arranged along the axial direction of the main body, enabling the wire to pass through the main body, preventing the wire from contacting the patient, and improving safety. The strain gauge, circuit board, and alarm are all existing and mature spare parts, and their specific structures and models will not be elaborated.

[0009] In the monitoring structure of a dental pad for surgery described above, the bottom surface of the cover plate is tightly attached and pressed against the strain gauge, and the circumferential outer sidewall of the cover plate is closely attached to the groove wall of the installation groove. This structure enables the force exerted by the patient biting on the cover plate to be better transmitted to the strain gauge, and prevents the patient's saliva, etc. from contacting the strain gauge, improving the detection accuracy of the strain gauge and avoiding damage to the patient's teeth during surgery.

[0010] In the monitoring structure of a dental pad for surgery described above, the cross-section of the through hole is circular, the cross-section of the main body is square with rounded corners, and the wire passing hole is located at the corner of the main body. The corner of the main body has sufficient thickness, providing enough space to open the wire passing hole, with a reasonable design.

[0011] In the above monitoring structure of a dental pad for surgery, a baffle is provided at the middle of the body along its own axis. The baffle divides the body into an inner section and an outer section. The installation groove is located in the inner section, and the installation groove is adjacent to the baffle. The wire passing hole is located in the outer section. The baffle can be embedded between the teeth and the lips to limit the position of the dental pad, position the body, and enable the patient's teeth to bite on the strain gauge, improving the detection accuracy of the strain gauge and avoiding the problem of tooth damage to the patient during surgery.

[0012] In the above monitoring structure of a dental pad for surgery, the number of the installation grooves is one. The installation groove is a rectangular groove. The strain gauge is in the shape of a thin sheet and is disposed closely against the bottom of the installation groove. When placing, align the position where the strain gauge is located with the teeth. Only one strain gauge is needed to accurately sense the biting force of the teeth, reducing costs.

[0013] As another case, in the above monitoring structure of a dental pad for surgery, the number of the installation grooves is 2 - 6. The installation grooves are rectangular grooves. All the installation grooves are arranged at equal intervals in a ring shape, and the strain gauge is disposed in each installation groove. This structure ensures that the strain gauge deforms when the teeth bite, improving the detection accuracy.

[0014] As a third case, in the above monitoring structure of a dental pad for surgery, the number of the installation grooves is one. The installation groove is in a ring shape. The strain gauge is in a long strip shape and is disposed around and closely against the bottom of the installation groove. This structure ensures that the strain gauge deforms when the teeth bite, improving the detection accuracy.

[0015] Compared with the prior art, the monitoring structure of a dental pad for surgery provided by the present utility model has the following advantages:

[0016] 1. A monitoring structure is provided in this dental pad. The biting force of the patient's teeth is sensed by the strain gauge. When the circuit board collects that the change in the resistance value of the strain gauge is too large, the alarm emits an alarm sound to remind the medical staff that the biting force of the patient's teeth is too large, enabling the medical staff to take some measures in time to avoid the problem of tooth damage to the patient.

[0017] 2. The main body of this dental pad is made of silica gel or rubber material, which can reduce the damage to the patient's teeth compared with the body made of plastic material. BRIEF DESCRIPTION OF THE DRAWINGS
