Description

Bite-block of sustainable connection negative pressure

Technical Field

The utility model belongs to the field of medical equipment, concretely relates to bite-block of sustainable connection negative pressure.

Background

Clinically, trachea cannula patients or coma patients sometimes need to insert a trachea from the mouth for breathing, but the brain of the patients still has thinking ability, still has autonomous and involuntary reflexes, and often has a tooth biting phenomenon, so that generally a bite block is needed for protection.

The existing common bite-block can only assist in fixing the tracheal intubation catheter, prevent a patient from biting the catheter and provide a cavity passage for facilitating medical staff to absorb oral secretion. However, in the actual use process, several defects are found:

1. the existing bite-block is only hollow in one cavity and cannot be connected with a negative pressure suction device, and when oral secretion of a patient with tracheal intubation increases, the oral secretion can flow out along the hollow part, so that the local part is not clean; because the bite block can not be connected with negative pressure, the sputum suction tube is needed for sucking sputum, and the mucosa can be damaged by repeatedly sucking sputum, so that the cost of a patient is increased; the oral secretion is accumulated, and the smell is bad under the condition that the oral secretion cannot be removed in time;

2. the existing common bite block cannot be fixed in the oral cavity, and a restless patient can spit the bite block outwards or slightly swallow the bite block inwards, so that potential safety hazards are caused;

3. the existing common bite-block has no pressure reducing device, and pressure injury around the oral cavity can be caused by long-time fixation.

Therefore, it is necessary to develop a new bite block to solve the above problems.

Disclosure of Invention

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

the utility model provides a bite-block of sustainable connection negative pressure, includes the bite-block main part, the bite-block main part is equipped with the cylindricality structure of first passageway for inside, and bite-block main part below is equipped with negative pressure chamber, negative pressure chamber front end seals and only stays circular negative pressure interface, negative pressure chamber rear end is equipped with the suction inlet, the rear end and the negative pressure chamber of first passageway pass through the through-hole intercommunication, the top surface of bite-block main part and the equal vertical radial limiting plate that is equipped with in middle part position of bottom surface, the rear end of limiting plate are equipped with the screens board of slope, and the limiting plate is equipped with decompression rubber cushion with the opposite face of screens board.

As an improvement of the utility model, the left side and the right side of the bite block main body are arcs of an inner concave.

As an improvement of the utility model, the rear end of limiting plate is equipped with anti-skidding district, anti-skidding district surface is equipped with fine bump or sand grip.

As an improvement of the utility model, the bite-block body is integrated with the limiting plate and the clamping plate.

As an improvement of the utility model, the inclined angle of the blocking plate is inclined backwards by 10-30 degrees.

As an improvement of the utility model, the height that highly is less than the limiting plate of screens board.

As an improvement of the utility model, the longitudinal section of the suction port is rectangular.

The utility model has the advantages that:

(1) a negative pressure cavity is added in the bite block and can be connected with a continuous negative pressure suction device, so that oral secretion can be continuously sucked, and normal humidity of the oral cavity is kept; the sucking of the redundant oral secretion can reduce the choking stimulation to the patient and reduce the occurrence of the pneumonia related to the breathing machine; the continuous suction can reduce the use of a sputum suction tube, reduce the stimulation on oral mucosa, reduce the damage of the oral mucosa and simultaneously reduce the cost burden of a patient; reduction of oral secretions can reduce patient oral odor;

(2) the added upper sealing layer of the negative pressure cavity is communicated with the first channel in the bite block main body through the through hole, so that when the oral secretion is more, the secretion shunted on the upper cavity can be sucked under the negative pressure state of the lower cavity;

(3) an inclined clamping plate is added at the rear end of the limiting plate, so that teeth can be fixed in the middle, and the risks of spitting and swallowing parts of the bite block by a patient are reduced;

(4) the opposite face of limiting plate and screens board increases rubber class or silica gel class cushion, can make patient's gum reduce pressure type and damage the risk.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments, which are to be understood as illustrative only and not limiting the scope of the invention.

As shown in the drawing, bite-block of sustainable connection negative pressure, including bite-block main part 1, bite-block main part 1 is equipped with the cylindricality structure of first passageway 2 for inside, and 1 below of bite-block main part is equipped with a negative pressure chamber 3 that link up, 3 front end seals in negative pressure chamber only keeps circular

negative pressure interface

4, 3 rear ends in negative pressure chamber are equipped with suction inlet 5, the rear end of first passageway 2 and negative pressure chamber 3 pass through-hole 6 intercommunication, the equal vertical radial limiting plate 7 that is equipped with of middle part position of the top surface of bite-block main part 1 and bottom surface, the rear end of limiting plate 7 is equipped with the screens board 8 of slope, and the limiting plate 7 is equipped with decompression rubber 9 with the opposite face of screens board 8.

A bite-block of sustainable connection negative pressure, have four improvement points:

1. a semi-closed negative pressure cavity 3 is added on the basis of the original bite block, the closed end is externally connected with a circular negative pressure interface 4 matched with a continuous negative pressure suction pipeline, and the other end is provided with a rectangular suction port 5, so that oral secretion can be continuously sucked, and the normal humidity of the oral cavity is kept; the sucking of the redundant oral secretion can reduce the choking stimulation to the patient and reduce the occurrence of the pneumonia related to the breathing machine; the continuous suction can reduce the use of a sputum suction tube, reduce the stimulation on oral mucosa, reduce the damage of the oral mucosa and simultaneously reduce the cost burden of a patient; the reduction of oral secretions can reduce the oral malodor of a patient.
