[Prior Art] Negative Pressure Wound Therapy is mainly attached to a wound by a sealing patch, a soft suction cup, or a biocompatible porous material, and is connected to an actuator to form a negative pressure environment in the wound. In order to accelerate wound healing by extracting wound pus and infectious substances, and attracting healthy tissue fluid to maintain a moist treatment environment and promote peripheral blood microcirculation. The conventional negative pressure wound care system connects the prior art actuator to the rear end of the liquid collection housing, and the liquid collection housing and the patch attached to the wound are connected to the Lipu in the actuator. The wound and the liquid collecting shell are both formed into a negative pressure environment and the waste liquid is extracted into the liquid collecting shell for collection, but the actuator is disposed at the rear end of the liquid collecting shell, meaning that the pump is far away from the wound. The pump requires a large amount of energy to achieve the function of forming a negative pressure environment and extracting waste liquid. Therefore, the prior art negative pressure wound care system has planned to directly attach the actuator to the patch attached to the wound. Connected, the rear end of the actuator is then connected to the liquid collection device to introduce the waste liquid into it for collection, and, in this way, the configuration mode will inevitably pass the waste liquid through the actuator, based on hygiene regulations and For human safety considerations, all medical devices that are in contact with human body or tissue fluid must be made of biocompatible materials, but the pump is made of biocompatible materials. Overall manufacturing cost, and Lipu damage needs to be replaced , 201200174 It is also necessary to increase the disposal time when it is discarded. It must be in accordance with the treatment mode of medical waste. SUMMARY OF THE INVENTION In view of the above, the present invention is directed to an actuator such that the pumping of the actuator does not need to be made entirely of a biocompatible material to reduce manufacturing costs and waste costs.

The actuator of the present invention is applied to a negative pressure wound care system, and the actuator is connected to the transmission wheel of the motor through the passive joint of the fruit, and the starter motor can drive the head to form a negative pressure aid in the wound. ; % and absorb pus and infectious substances. The invention has the advantages that the actuator is independent and the motor is separable, and since the extracted waste liquid is pumped through the pump, only the pump head must be made of bio-grain material. Into the 'not only lower your sergeant 1 cattle and his cost" and in the subsequent maintenance, only the infected actuator can be replaced and treated with medical waste procedures without the need to replace the motor, motor extension In the case of failure, it can only be handled in the normal way 4 201200174, which can effectively reduce maintenance and disposal costs. Further, the present invention can be interfaced with the sensor of the negative pressure wound care system, so that the sensor directly detects the negative pressure of the wound, and the inlet connecting tube cutter is connected to the inlet joint of the pump head and the sensor. The liquid connection of the connected liquid is connected with a current limiting unit to prevent the waste liquid from being inadvertently poured into the sensor, and the current limiting unit can be a spiral tube to pull in a very short pipeline length. The long liquid flow path can achieve the effect of water blocking. [Embodiment]

Referring to Figures 1 and 2, the actuator i of the present invention comprises a "body 1", a chestnut head 20, an inlet connecting tube 30 and an outlet connecting tube 4''. The body 10 is hollow and has a fluid connector on one side, and the fluid is provided with a biological isolation unit <1, and the biological isolation unit (1) is used to block the infiltration of the infectious material from the fluid connector 丨i. The pump head 20, which is not described in Fig. 2, is disposed in the casing 10, and the 1st 20 is made of a biocompatible material, and the pump head 20 has a port joint 21 and an outlet joint 22 on the side. The box mouth is connected to the master 23.帛 2 pump head 20 is provided on the other side - passive connection, L connection e 30 is compared with pump head 20 and fluid connection 11 respectively = tube 3 ° can be - diverting element and has a plurality of flow channels, and -= = 'Population connection pipe 3G has a communication-first flow channel 31 channel 2 The first flow channel 31 is connected to the D joint η, and the second flow 32 is connected to the fluid joint U. ί S3 The aforementioned outlet connecting pipe 40 is connected to the outlet joint 22 of the pump head 20 and 5 201200174 extends out of the casing 1 . The actuator 1 of the present invention can be applied to various negative pressure wound care systems. Referring to Figures 3 and 4, an illustration of one of the negative pressure wound care systems is shown. The actuator 1 of the present invention is applied to the negative pressure wound shown. In the care system, the actuator ι is coupled to the sensor 50, the sensor 5A has a corresponding fluid connector 5 i, and the sensor 50 is provided with a motor 52 for driving the head 2 ,, the drive shaft of the motor 52 The 521 is inserted into the passive joint 23 of the pump head 2 of the actuator i, and the sensor 50 is further connected to the controller 60. The first passage 31 of the diverter element of the actuator ι is combined with the wound dressing dressing 70. Connected, the outlet connection tube 40 of the actuator.1 is connected to the liquid collection device 80. Referring to Figures 2, 3 and 4, the wound dressing dressing 70 is used to attach to the user's wound. When the negative pressure wound care system is activated, the motor 52 drives the pump in the actuator ι. The head 2 forms a negative pressure environment on the wound and absorbs the gland fluid and the infectious substance. At this time, the waste liquid flows into the pump head 20 through the first flow path 31, and then flows out of the pump head 20 through the outlet connecting pipe 4 and flows into the liquid collecting device 8. 0 is collected, so that the waste liquid passes only the actuator ι and not through the motor _ 5 2 , and the motor 52 and the actuator ι are detachable, only the pump head 20 in the actuator 1 The inlet connection tube 30 and the outlet connection tube 4 are not required to be made of a biocompatible material, which saves manufacturing costs and uses a detachable design to allow the user to disassemble and replace the contaminated actuator 1 but The motor 52 is still sustainable and can also reduce subsequent maintenance costs. Further, since the sensor 50 transmits the negative pressure value of the wound through the fluid joints 51, n and through the second flow path 3 2, when the waste liquid flows into the first flow path 31 of the mouth connecting pipe 30, it is not It is avoided that some of the waste liquid is inadvertently poured into the second flow path 32 'but the sensor 50 only needs to measure the pneumatic force and 201200174 does not pay the liquid to fill in. Therefore, the current limiting unit is required in the second flow path 32. To prevent liquid from entering the sensor, in the preferred embodiment, the confining tube 33 is plugged into the second flow path 32. When the waste liquid flows into the second stream =, the waste liquid will flow along the spiral path of the spiral tube 33. , the flow path of the liquid is greatly extended in a very short length, so that the flow channel: the waste liquid is blocked in the spiral tube 33 without damage detection and the excess volume 33 is set. It is effective to extend the flow path but does not increase the weight shown in Fig. 5 to Fig. 7. In the housing 10A, the upper part of the housing 10A is directly mounted on the actuating motor 52A and still passes through the transmission shaft 521A盥A. Removably connected, the motor 52A is remarked by the connector 5 to be connected to the sensor-like electrical connector. The 52A and the Chestnut 2〇A are separable designs to achieve the cost and lower maintenance costs.
