Description
本發明與呼吸器有關，尤指一種用於呼吸器之測試治具。The invention relates to a respirator, and more particularly to a test fixture for a respirator.
當病患無法自行呼吸或是可以自行呼吸但無法達到人體所需要的氧氣濃度時，通常需要加裝呼吸器以延續病患的生命。在安裝呼吸器之前，護理人員必須先依照病患的狀況對呼吸器設定相關的呼吸參數(如潮氣容積、呼吸速率及每分鐘通氣量等)，讓病患能夠藉由呼吸器得到適當的治療。When a patient is unable to breathe on their own or can breathe on their own but cannot reach the oxygen concentration required by the body, it is usually necessary to install a respirator to continue the life of the patient. Before installing the respirator, the caregiver must first set the relevant breathing parameters (such as tidal volume, respiration rate, and minute ventilation) according to the patient's condition, so that the patient can get proper treatment by the respirator. .
在使用呼吸器的過程中，同時會藉由感測器即時感測病患的狀況，一旦感測結果出現異常時，呼吸器會立刻發出警示訊號通知護理人員前來檢查病患的狀況，然而，如果呼吸器在出廠時所設定的參數範圍不夠精確，在實際使用時可能會被感測器的感測結果所影響而造成誤判。有鑑於此，本案之創作人遂提供一種測試治具，主要用來測試呼吸器在出廠時的各項功能，以便提升在參數設定上的精確度。In the process of using the respirator, the condition of the patient is immediately sensed by the sensor. Once the sensing result is abnormal, the respirator immediately sends a warning signal to inform the nursing staff to check the condition of the patient. If the range of parameters set by the respirator at the factory is not accurate enough, it may be affected by the sensor's sensing result and cause misjudgment. In view of this, the creator of the case provides a test fixture, which is mainly used to test various functions of the respirator at the factory to improve the accuracy of parameter setting.
本發明之主要目的在於提供一種用於呼吸器之測試治具，其結構簡單且操作方便，並且能讓呼吸器模擬不同的情境進行不同功能的測試，藉以提升在參數設定方面的精確度。The main object of the present invention is to provide a test fixture for a respirator which is simple in structure and convenient to operate, and allows the respirator to simulate different situations for testing different functions, thereby improving the accuracy in parameter setting.
為了達成上述目的，本發明之測試治具包含有一驅動單元與一供氣單元。該驅動單元具有一驅動源，該供氣單元具有一儲氣筒與一活塞桿，該儲氣筒連接一呼吸器，活塞桿之一端穿設於該儲氣筒內，該活塞桿之另一端位於該儲氣筒外且連接該驅動源。藉此，該活塞桿能藉由該驅動源之驅動而相對該儲氣筒產生不同速率的軸向移動，用以供給不同壓力的空氣至該呼吸器，讓該呼吸器能夠進行不同功能的測試。In order to achieve the above object, the test fixture of the present invention comprises a drive unit and a gas supply unit. The driving unit has a driving source, and the air supply unit has a gas cylinder and a piston rod. The air cylinder is connected to a respirator. One end of the piston rod is disposed in the air reservoir, and the other end of the piston rod is located at the storage. The drive source is connected outside the gas cylinder. Thereby, the piston rod can generate different axial movements relative to the air reservoir by driving the driving source to supply different pressures of air to the respirator, so that the respirator can perform different functions.
更佳地，該驅動單元更具有一轉盤與一曲柄臂，該驅動源具有一驅動軸，該驅動軸以同軸方式連接該轉盤，該曲柄臂之一端樞設於該轉盤，該曲柄臂之另一端樞設於該活塞桿，藉此，該轉盤能藉由該驅動源之驅動軸的驅動而轉動，並且在轉動過程中透過該曲柄臂帶動該活塞桿，使該活塞桿能相對該儲氣筒產生軸向移動。More preferably, the driving unit further has a turntable and a crank arm, the drive source has a drive shaft, the drive shaft is coaxially connected to the turntable, one end of the crank arm is pivoted on the turntable, and the crank arm is another One end is pivotally disposed on the piston rod, whereby the turntable can be rotated by driving of the driving shaft of the driving source, and the piston rod is driven by the crank arm during rotation so that the piston rod can be opposite to the air reservoir Produces axial movement.
更佳地，該活塞桿之一端套設有一滑塊，該滑塊樞設於該曲柄臂且架設於一滑軌上，該滑軌之延伸方向平行於該活塞桿之移動方向，如此即能提升該活塞桿的作動穩定性。More preferably, one end of the piston rod is provided with a slider, the slider is pivotally disposed on the crank arm and is mounted on a sliding rail, and the extending direction of the sliding rail is parallel to the moving direction of the piston rod, so that Improve the actuation stability of the piston rod.
請先參閱第1及2圖，本發明之測試治具10包含有一驅動單元20及一供氣單元30。Please refer to FIGS. 1 and 2 first. The test fixture 10 of the present invention includes a driving unit 20 and a gas supply unit 30.
驅動單元20具有一驅動源21、一轉盤22，以及一曲柄臂23。驅動源21在此以馬達為例且具有一驅動軸24；轉盤22以同軸方向連接驅動源21之驅動軸24，使得轉盤22能被驅動源21所驅動而轉動；曲柄臂23之一端樞設於轉盤22，使得曲柄臂23能藉由轉盤22之轉動而往復移動。The drive unit 20 has a drive source 21, a turntable 22, and a crank arm 23. The drive source 21 is exemplified by a motor and has a drive shaft 24; the turntable 22 is connected to the drive shaft 24 of the drive source 21 in a coaxial direction, so that the turntable 22 can be driven to rotate by the drive source 21; one end of the crank arm 23 is pivoted At the turntable 22, the crank arm 23 can be reciprocated by the rotation of the turntable 22.
供氣單元30具有一儲氣筒31與一活塞桿32。儲氣筒31用來連接一呼吸器(圖中未示)，活塞桿32之一端穿設於儲氣筒31內，活塞桿32之另一端位於儲氣筒31外。The air supply unit 30 has an air reservoir 31 and a piston rod 32. The air reservoir 31 is used to connect a respirator (not shown). One end of the piston rod 32 is disposed in the air reservoir 31, and the other end of the piston rod 32 is located outside the air reservoir 31.
在此需要補充說明的是，為了增加活塞桿32的作動穩定性，本發明更提供一導引單元40，導引單元40具有一滑軌41與一架設於滑軌41之滑塊42，滑軌41之延伸方向平行於活塞桿32之移動方向，滑塊42套設於活塞桿32外露於儲氣筒31之一端且樞接於曲柄臂23之另一端，使得滑塊42能藉由曲柄臂23之帶動而驅使活塞桿32相對儲氣筒31產生軸向位移。In addition, in order to increase the stability of the piston rod 32, the present invention further provides a guiding unit 40. The guiding unit 40 has a sliding rail 41 and a slider 42 mounted on the sliding rail 41. The extending direction of the rail 41 is parallel to the moving direction of the piston rod 32, and the slider 42 is sleeved on the piston rod 32 to be exposed at one end of the air reservoir 31 and pivoted to the other end of the crank arm 23, so that the slider 42 can be driven by the crank arm The driving of 23 drives the piston rod 32 to axially displace relative to the air reservoir 31.
在實際操作時，如第3及4圖所示，首先啟動驅動源21，驅動源21之驅動軸24會帶動轉盤22開始轉動，在轉盤22轉動的過程中會同時帶動曲柄臂23，接著曲柄臂23會透過滑塊42帶動活塞桿32相對儲氣筒31前後位移，如此即能將空氣持續不斷地輸送至呼吸器。另一方面，為了測試呼吸器的不同功能，可以根據實際需要進一步調整驅動源21的轉速，使活塞桿32能夠以不同的速度進行軸向移動，藉以產生不同壓力的空氣至呼吸器。又或者是，可以調整活塞桿32相對儲氣筒31的軸向位置與進給行程，進而改變活塞桿32在儲氣筒31內部所能夠推送的空氣容量，更加提供精確的測試參數與狀態至呼吸器。In actual operation, as shown in Figures 3 and 4, the driving source 21 is first activated, and the driving shaft 24 of the driving source 21 drives the turntable 22 to start rotating. During the rotation of the turntable 22, the crank arm 23 is simultaneously driven, and then the crank is driven. The arm 23 drives the piston rod 32 to move back and forth relative to the air reservoir 31 through the slider 42 so that the air can be continuously delivered to the respirator. On the other hand, in order to test the different functions of the respirator, the rotational speed of the driving source 21 can be further adjusted according to actual needs, so that the piston rod 32 can be axially moved at different speeds, thereby generating air of different pressures to the respirator. Or alternatively, the axial position and the feed stroke of the piston rod 32 relative to the air reservoir 31 can be adjusted, thereby changing the air capacity that the piston rod 32 can push inside the air reservoir 31, and further providing accurate test parameters and states to the respirator. .
綜上所陳，本發明之測試治具10除了具有結構簡單且操作方便的特色之外，最重要的是能夠模擬各種不同狀況來產生不同壓力的空氣，讓呼吸器可以進行多種不同功能的測試來修正相關的參數設定，進而達到提升精確度的目的。In summary, in addition to the features of simple structure and convenient operation, the test fixture 10 of the present invention is capable of simulating various conditions to generate different pressures of air, allowing the respirator to perform various functions. To correct the relevant parameter settings, in order to achieve the purpose of improving accuracy.
