Abstract

SOLUTION: The discharge side pump head 2 and the suction side pump head 3 installed in the casing 1 are driven by separate motors 4, 4a, and the discharge side pump head is provided. Is connected to a discharge pipe 6 connected to an outside air introduction pipe 5 and an inhaler 8, and a suction pipe 9 for sucking airway secretions and an exhaust pipe 10 are connected to the pump head 3 on the suction side. And the circuit for the aspirator are separated and independent from each other to constitute a therapeutic pump device. [Effect] Since the circuit for the inhaler and the circuit for the aspirator are made independent, one device can be used for both inhalation and aspiration, and there is no possibility that suction dirt is mixed into the inhaler.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an inhaler for nebulization therapy used for treatment of bronchial asthma and the like, and an inhaler for removing airway secretions such as sputum.

[0002]

[Prior art]

 Medical inhalers use the discharge force (positive pressure) of the pump to spray drugs and the like into the patient's airway. The inhaler uses the suction force (negative pressure) of the pump to extract the airway from the patient. It sucks litter and the like. As described above, both the inhaler and the aspirator are devices using the positive or negative pressure of the pump. The relationship is such that if the positive pressure is used, the device becomes an inhaler, and if the negative pressure is used, the device becomes a suction device. Therefore, both pump devices can be used in terms of mechanism. For example, in a pump device configured for an inhaler, if the distal end of the outside air introduction pipe is connected to a suction hose and air is exhausted from a discharge pipe that should be connected to the suction device, the pump device configured for an inhaler is used. It is structurally possible to use it as it is as a pump device for the suction device.

By the way, there is a risk that contaminants or bacteria such as airway secretions of the patient who have been sucked in flow into the pump head for the suction device, and the bacteria may propagate. When one pump head is used for both the inhaler and the aspirator, bacteria that flow into the pump head when used for the aspirator are sprayed from the inhaler when used for the inhaler and sent to the patient. May be In particular, when a single pump device is used by many patients in a hospital, bacteria sucked from one patient will be sucked into another patient, and there is a high possibility of causing bacterial infection. Therefore, they are not used at hospitals.

[0004] In addition, although there is no risk of bacterial infection in home care patients, it is needless to say that bacteria are not preferably contained in the inhalant. However, since this type of pump device is expensive, preparing two units for the inhaler and for the inhaler is economically burdensome, and in reality many patients share one unit. .

[0005]

[Problems to be solved by the invention]

 The purpose of the present invention is to obtain a sanitary pump device that is also used as a suction device for an inhaler by preventing sucked dirt and bacteria from being sent to the patient during inhalation.

[0006]

[Means for Solving the Problems]

 In this invention, a discharge-side pump head for suction and a suction-side pump head for suction are separately prepared, an outside air introduction pipe and a discharge pipe are connected to the discharge-side pump head, and a suction pipe is connected to the suction-side pump head. And the exhaust pipe, and completely separate and separate the circuit for the aspirator and the circuit for the inhaler. The two pump heads are driven by separate motors to solve the above problem. In the invention of claim 2, a storage container for storing the suctioned material and a safety container for preventing the suctioned material having passed through the storage container from flowing into the pump head are connected to the tip side of the suction pipe. It is.

[0007]

[Action]

 When the pump device of the present invention is used for a suction device, a suction hose is connected to a suction pipe connected to the suction side pump head, and the suction side pump head is driven. At this time, although the sucked dirt and bacteria may flow into the suction side pump head, there is no possibility that bacteria and the like flow into the discharge side pump head because the circuit is independent of the suction side. On the other hand, when used for an inhaler, connect the suction device to the discharge pipe connected to the discharge side pump head and drive the discharge side pump head. Here, since the discharge side pump head is independent of the suction side pump head, there is no possibility that the inhalant contains bacteria. Also, since the motor drive section of this device operates independently, it is possible to control the motor drive individually and stop when not in use, unlike when a single motor is used for both purposes. There is also.

[0008]

[Embodiment of the invention]

 A discharge side pump head 2 used for an inhaler and a suction side pump head 3 used for a suction device are installed in a closed casing 1. These two pump heads 2 and 3 are provided with separate motors 4. , 4a. An outside air introduction pipe 5 and a discharge pipe 6 are connected to the discharge side pump head 2. The tip of the outside air introduction pipe 5 is connected to an outside air introduction section of the casing 1, and a filter 7 is attached to the outside air introduction section. The end of the discharge pipe 6 is open to the outer surface of the casing 1 so that it can be connected to an appropriate inhaler 8.

A suction pipe 9 and an exhaust pipe 10 are connected to the suction side pump head 3. The suction tube 9 is connected to a suction hose 11. In the figure, between a suction pipe 9 and a suction hose 11, a storage container 12 for storing the suctioned material and a safety container for preventing the suctioned material passing through the storage container 12 from flowing into the pump head 3. 13, and a filter 14 is provided between the storage container 11 and the safety container 13. The exhaust pipe 10 is connected to an exhaust port provided on the bottom surface of the casing 1, and a filter 15 is provided at the exhaust port.

[0010]

[Effect of the invention]

 According to this invention, two pump heads and two motors are provided, and the discharge side circuit used for the inhaler and the suction side circuit used for the aspirator are completely separated and independent. Even if dirt and bacteria flow into the suction-side pump head at the time of cleaning, there is no danger that the sucked bacteria will be inhaled when used for an inhaler. In addition, in this invention, two pump heads and two motors are installed in one case, so that the suction and suction devices can be integrated, and when used, the suction or suction individual pump is used. It can be used by operation, and is also a measure against noise such as operation noise.
