Problems solved by technology
[0004] 1. The pipeline from the vacuum pump 100 to the wound 500 is too long, which is inconvenient to use, easy to leak, and wastes vacuum energy
[0005] 2. The vacuum pump 100 must use a high-power motor based on factors such as power, noise, and service life, which makes the pump motor too heavy and expensive
[0006] 3. The power consumption of the pump motor is high, and it must be equipped with a large battery module 700, which increases the volume and weight
[0007] 4. The waste liquid storage tank 600 is large in volume, takes up space and is not easy to carry
[0008] 5. The waste liquid is easily polluted or shut down due to the shaking and dumping of the waste liquid storage tank 600
[0009] 6. The volume and weight of the overall system cannot be effectively reduced, which is unfavorable for patients to carry
[0010] Among the known patents, such as U.S. Patent No. 7216651 "Wound treatment employing reduced pressure", the negative pressure wound therapy system disclosed in this patent is connected in series in the order of traditional dressing, waste liquid container and pump, so the design structure is huge and complicated and expensive
[0011] Another example is U.S. Patent No. 5,549,584 "Apparatus for removing fluid from awound", which discloses a wound waste liquid extraction device, which connects the wound dressing to a bellows pump, and the bellows pump is then connected to a waste liquid collection bag. Although the series sequence of the dressing, pump, and waste liquid collection bag in this extraction device is different from the traditional series method, because the bellows pump provides negative pressure manually, the operation method is simple, but the pressure cannot be precisely controlled, and the curative effect is questionable. , and not suitable for larger wounds
[0012] Another example is U.S. Patent Publication No. 2007 / 0055209 "Self contained wound dressing apparatus". The wound dressing control device disclosed in this patent is connected in series in the order of dressing, pump, and waste liquid container, but the pump adopts a peristaltic pump with extremely high suction capacity. Small, but if you want to increase the suction capacity, you must increase the pump, which will lead to a large volume

Embodiment Construction
[0076] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, it will be described in detail below with reference to the accompanying drawings and examples, but the accompanying drawings and examples are only auxiliary descriptions, and the present invention is not limited to the accompanying drawings and examples. Example.
[0077] see figure 2 and image 3As shown, the detachable pump 800 provided by the present invention is mainly composed of an upper module 800a and a lower module 800b which can be assembled and disassembled by motor.
[0078] The upper module 800a includes a winding seat 807, the winding seat 807 has a central axis C, and a coil 808 is wound outside the winding seat 807, and the coil 808 is connected to an external current (not shown in the figure), by The winding base 807 and the coil 808 form a mover group; the upper module 800a further includes a magnet group composed of an inner magneti...

The invention relates to a removable pump and a negative pressure wound treatment system using same. The removable pump comprises an upper module and a lower module. The upper module comprises a motor set and an elastic component. The lower module is connected with the lower part of the upper module by a removable conjunction structure and comprises a base, at least a suction check valve, at least a discharging check valve, a thin-film device and a lower elastic component. The base is provided with at least a suction passage and at least a discharging passage. The suction check valve and the discharging check valve are used for avoiding that waste liquor reflows to a wound or the base. The motor set can push the elastic component. And the mutual balance elastic of the lower elastic component and the upper elastic push the thin-film device pushes the thin-film device to form pump sucking power. The removable pump is matched with dressing and absorbing material and is applied in the negative pressure wound treatment system. After wound waster liquor passes through dressing and the pump, the wound waster liquor is absorbed directly by the absorbing materials; therefore, the purposes of shortening the length of a pipeline, reducing the volume of a negative vessel and reducing the power of the battery module and the pump, and the like are achieved.
Description
technical field [0001] The present invention relates to a pump and a negative pressure wound treatment system using the pump, in particular to a detachable pump and a negative pressure wound treatment system using the pump. Background technique [0002] Traditional negative pressure trauma therapy systems, such as figure 1 As shown, a vacuum pump 100 is used in combination with a sealing patch 200, a soft suction cup (not shown) and a biocompatible pore dressing 300. The dressing 300 is connected to a pipeline 310 to a waste liquid storage tank 600. The waste liquid storage tank 600 Then connect the pipeline 110 to the vacuum pump 100 to form a negative pressure environment in the wound 500 of the skin 400, extract the pus and infectious substances in the wound 500, attract healthy tissue fluid to maintain a moist treatment environment, and promote the surrounding blood microcirculation, thereby achieving acceleration. The effect of wound healing. [0003] The main purpose...
