Description

An ENT postoperative nursing device and its adjustment method

technical field

The invention relates to the technical field of ENT nursing care, in particular to an ENT postoperative nursing device, and at the same time, the invention also relates to an adjustment method for the ENT postoperative nursing device.

Background technique

Many laryngeal operations need to cut the trachea during the operation. When the trachea is cut, the respiratory tract will lose its function of heating, humidifying, filtering, cleaning and retaining the inhaled gas, and various related diseases are prone to occur. complication. Therefore, in order to achieve sufficient airway humidification, the method of dripping or micropumping humidification solution into the airway is often used to humidify the airway to reduce the formation of sputum scab, promote the discharge of sputum, and reduce lung infection. The method of dripping or micro-pumping humidifying fluid into the airway is widely used in clinical practice because of its simple, economical and effective materials. It has the advantages of continuously pumping a very small amount of humidifying fluid into the airway, causing little irritation to the airway, avoiding choking cough or irritating cough, and having no discomfort for the patient.

In actual use, in order to avoid choking or irritating cough, the amount of humidification solution is relatively small. Therefore, after long-term use, the problem of insufficient airway humidification is prone to occur. In most cases, patients can only solve the above problems by accompanying family members or medical staff, and it is difficult for patients to solve them by themselves. However, after throat surgery, it is not convenient for the patient to speak, which will lead to the problem of inconvenient communication. Therefore, in many cases, if the patient has only a little discomfort, he usually tolerates it on his own. Humidification devices are used together to make adjustments more convenient, while avoiding outsourcing or customizing expensive equipment with similar functions will greatly improve patient comfort and reduce patient medical expenses.

The first adjustment assembly includes an elastic support plate 16, the upper end of the elastic support plate 16 is provided with triangular ribs 1601, and the lower side of the elastic support plate 16 is provided with a transmission plate 17, the transmission plate 17 is L-shaped, and the transmission plate 17 passes through The guide rod 18 is slidingly connected with the support base 3 , one end of the transmission plate 17 is in contact with the elastic support plate 16 , and the other end of the transmission plate 17 is fixedly connected with the second gate plate 8 . Two damping rods 19 are provided on the side of the supporting base 3 close to the elastic support plate 16 , and one end of the damping rods 19 is fixedly connected to the elastic support plate 16 .

In order to solve the problem that it is difficult for the patient to complete the airway humidification adjustment by himself, a support seat 3 is provided on the underside of the pillow 1 in this technical solution, and a flow adjustment mechanism is arranged in the support seat 3, and the flow adjustment assembly at the pillow 1 The flow rate of the humidifying fluid can be adjusted. In actual use, the patient only needs to press the elastic support plate 16 downward with the head. Driven by the elastic support plate 16, the second gate 8 will move away from the valve body 4 After losing the resistance of the second gate 8, the cross-section of the internal channel of the valve body 4 becomes larger, and the flow rate of the humidification liquid also becomes larger.

Specific working principle: there is a sponge in the pillow 1, and the humidification fluid enters the support seat 3 from the liquid inlet pipe 5, and then flows out through the liquid outlet pipe 6. When the patient feels uncomfortable due to the small flow of the humidification fluid, just use The head presses the elastic support plate 16 downward, and the elastic support plate 16 deforms, thereby pushing the transmission plate 17 to move. The transmission plate 17 is fixedly connected with the second gate plate 8, and the transmission plate 17 will drive the second gate plate 8 when it moves. Together with the movement of the second gate 8, the cross section of the internal channel of the valve body 4 becomes larger, and the flow rate of the humidifying fluid also increases.

The first flashboard (7) conflicts. 8. An ENT postoperative care device according to claim 7, characterized in that: the support seat (3) is provided with a second adjustment device for adjusting the height of the second shutter (8) assembly, and the second adjustment assembly includes an air bag (28) and a connecting pipe (29), the air bag (28) is located on the upper side of the transmission plate (17), and one end of the connecting pipe (29) is connected to the The air bag (28) is connected, the air bag (28) has a built-in pressure sensor, and the other end of the connecting pipe (29) is provided with an air pressure chamber (30), and the air pressure chamber (30) is provided with a booster pump (31), and an electromagnetic one-way valve (32) is provided between the air pressure chamber (30) and the connecting pipe (29), and a pressure relief solenoid valve (33) is provided on one side of the connecting pipe (29). ); Wherein, also comprise a controller and be positioned at the distance sensor (34) of transmission plate (17) lower end, described controller comprises button, display screen and control circuit, wherein, described button controls booster pump by control circuit (31), electromagnetic one-way valve (32) and pressure relief electromagnetic valve, display screen is used for real-time display air bag (28) air pressure value. 9. The adjustment method of a kind of otolaryngology postoperative nursing device according to claim 8, characterized in that: comprising the steps of: S1. Equipment connection: place the pillow (1) on the hospital bed, then connect the liquid inlet pipe (5) with the humidification liquid storage bottle, and connect the liquid outlet pipe (6) with the oxygen pipe; S2. Preliminary debugging. In the initial stage of use, the flow rate of the humidification fluid needs to be adjusted so that it can meet the needs of actual use. Turn the adjusting bolt (27), and under the push of the adjusting bolt (27), the first gate (7 ) moves toward the valve body (4), and with the movement of the first gate (7), the cross section of the internal channel of the valve body (4) becomes smaller, and the flow rate of the humidifying fluid becomes smaller. When the flow rate meets the requirements, stop the twisting Adjusting bolt (27); S3. Head adjustment: when the humidification of the airway is insufficient due to long-term use, the patient can use the head to press the elastic support plate (16), and the second elastic support plate (16) and the transmission plate (17) can drive the second The gate (8) moves to increase the flow rate of the humidification fluid. When the patient stops pressing the elastic support plate (16), the elastic support plate (16) returns to its original position, and the flow rate of the humidification fluid returns to normal; S4, hand debugging: use the button of the controller to turn on the booster pump (31) to work, when the booster pump (31) is turned on to work, the electromagnetic one-way valve (32) is in the open state, and the air pressure in the air pressure chamber rises thereby The air bag (28) can be inflated through the connecting pipe (29). When the air bag (28) is inflated, the volume becomes larger, and the transmission plate (17) will be pushed down to move, and the transmission plate (17) will drive the second gate ( 8) Movement, which also serves the purpose of adjusting the flow rate of the humidifying fluid; the distance sensor (34) is used to sense the distance from the drive plate (17) to the support seat (3), and when the preset distance is reached, the controller forces Disconnect the booster pump (31) to work, and the electromagnetic one-way valve (32) is in the closed state after power failure, thereby avoiding the overload of the air bag (28) and causing the transmission plate (17) to be overstretched; when the air bag (28) is required to release pressure , the controller opens the pressure relief electromagnetic valve (33) through the button to perform the pressure relief operation; S5. Cut off flow of humidifying fluid: when the patient coughs, it is easy to inhale the humidifying fluid into the lungs. At this time, the patient only needs to raise his head, and the flow blocking mechanism in the pillow (1) can press the liquid inlet tube (5) Tight, so as to achieve the purpose of intercepting the humidification liquid.
