Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hoseless ventilator used for ventilation in otorhinolaryngological treatment, and a charging device thereof.

In recent years, there has been a tendency for many patients to concentrate in well-equipped hospitals, so doctors at such hospitals have to repeatedly perform medical treatment in a standing position or fill out medical records at desks. It won't happen. Therefore, in order to provide high-quality medical treatment with less fatigue, doctors have begun to request sitting-based medical treatment in which the doctor and patient can perform medical treatment while sitting together in a chair.

The present invention relates to a hoseless ventilator and its charging device, which are necessary to enable the above-mentioned sitting medical treatment in otorhinolaryngology.

[Conventional technology]

In otorhinolaryngology-related diseases, the eustachian tube may become narrowed or blocked due to a lesion or the like, making it difficult for air to reach the middle ear, which is connected to the eustachian tube. In such cases, the pressure balance between the middle ear and the outer ear is disrupted, causing the eardrum to bulge (feeling solid) or to hearing distance.

To treat this disease, there is a ventilation treatment that involves sending compressed air into the Eustachian tubes to widen them. This ventilation is achieved by inserting a European canal catheter into the Eustachian tube through the nasal cavity and injecting compressed air through the European canal catheter to widen the Eustachian tube.

Therefore, the number of outpatient treatments increases depending on the degree of stenosis or obstruction of the Eustachian tube.

However, the distance from the nasal cavity to the entrance of the Eustachian tube is usually more than 10 senna, and the path to the Eustachian tube curves differently depending on the person. Furthermore, a means for doctors to perform medical treatment while viewing the winding passages has not yet been developed.

Therefore, doctors rely on experience from the time the European tube catheter is inserted into the nasal cavity until the tip reaches the entrance of the Eustachian tube. In addition, the air pressure when performing ventilation is
Not only does it differ from person to person depending on the degree of narrowing or obstruction of the Eustachian tube, or the way it curves into the Eustachian tube, but it is also important to avoid giving unnecessary stimulation to other organs.

Therefore, conventionally, with your right hand, you hold the flexible rubber tube (compressed air introduction rubber tube) connected to the base of the European tube catheter, and while searching for the position of the tip of the European tube catheter, reach the Eustachian tube. was.

When the patient arrived, he used either his left or right hand to support the catheter and the other hand to adjust the compressed air.

[Problem to be solved by the invention]

However, the current situation is that the above-mentioned medical treatment performed in a standing position while using both hands causes severe fatigue for the doctor, which may even affect the quality of medical treatment.

Therefore, a seated medical treatment has been proposed in which the patient can sit while holding the vent with one hand, but this is not practical because the hose that supplies the compressed air gets in the way.

In addition, there were problems with the air pressure stored in the vent, and with the operability of the doctor when performing the above-mentioned complicated operations with one hand. In particular, when performing ventilation treatment, several tens of seconds or more are required, depending on the condition of the affected area. The number of times of ventilation can be determined in various ways depending on the condition of the affected area or the medical treatment method of the doctor. Therefore, if the hose that supplies air to the pressure storage tank is eliminated, there is a problem in maintaining the air pressure in the pressure storage tank necessary for ventilation.

In order to solve the above problems, it is an object of the present invention to provide a hoseless ventilator that does not require a hose for feeding compressed air and is lightweight and has good operability.

Another object of the present invention is to provide a hoseless ventilator that is suitable for intermittent ventilation because it prevents a decrease in air pressure during ventilation treatment and is ready to constantly supply air.

A further object of the present invention is to provide a hoseless ventilator charging device that can constantly replenish the air pressure of the ventilator appropriately.

[Means to solve the problem]

In order to achieve the above object, the hoseless ventilator of the present invention includes a pressure accumulation tank in which a compressor section for accumulating air pressure is provided at the bottom thereof, and an on-off control valve that is provided in the upper part of the pressure accumulation tank and is capable of adjusting the pressure. It consists of a pressure regulator and a vent pipe connected to the output part of the pressure regulator via a flexible pipe.

The hoseless pencil 9-(71) compressor section of the present invention is equipped with a battery that drives a motor that operates the compressor.

A part of the hoseless ventilator compressor according to the present invention is equipped with a control device that detects the air pressure in the pressure storage tank and stops the operation of the compressor.

A charging device for accumulating pressure in a hoseless ventilator according to the present invention includes a socket into which a pressure accumulating tank is inserted, and a power supply circuit provided below the socket via a connecting part.

[For production]

After performing the ventilation procedure, the physician inserts the ventilator into the socket. When the ventilator is inserted into the socket, it is connected to the power supply circuit via a connection provided at the bottom of the socket. Then, the motor of the compressor section provided at the lower part of the ventilator is driven to supply air to the pressure accumulation tank of the ventilator.

When the air pressure in the pressure storage tank reaches the specified pressure, the compressor power is automatically turned off, and the pressure in the pressure storage tank is always maintained at a constant air pressure.

In this way, the ventilator is always on standby.

The ventilator does not have a hose for supplying air, so the doctor holds the ventilator with one hand and, while sitting, puts the pressure storage tank in the palm of his hand, presses the on-off adjustment valve with his thumb to open it, and then inserts the European tube catheter into the ventilator. Adjust the air pressure coming out of the tip. Then, the patient holds the end of the European tube catheter with his index and middle fingers, and performs medical treatment while performing complicated operations with the three fingers and the palm of his hand.
