Therefore, the protection scope of the present invention is not limited by the specific details disclosed below. Example limitations.

下面参照图1和图2描述根据本发明的一些实施例。Some embodiments according to the present invention are described below with reference to FIGS. 1 and 2 .

如图1和图2所示，本发明的实施例提供了一种脑病科用冲洗器，包括：冲洗器本体10，冲洗器本体10内形成有引流腔体11以及清洗液腔体12，清洗液腔体12为环形且位于引流腔体11的周侧，冲洗器的周侧侧壁上设有与清洗液腔体12连通的出液口13；清洗液腔体12与清洗液储存袋20体通过注射装置30连通；引流腔体11与引流装置40连通；疏导装置50，滑动设于冲洗器本体10上且位于引流腔体11内，疏导装置50能沿引流腔体11往复滑动。As shown in FIG. 1 and FIG. 2 , an embodiment of the present invention provides an irrigator for encephalopathy, including: anirrigator body 10 , adrainage cavity 11 and a cleaningliquid cavity 12 are formed in theirrigator body 10 . Theliquid cavity 12 is annular and is located on the peripheral side of thedrainage cavity 11. The peripheral side wall of the flusher is provided with aliquid outlet 13 that communicates with the cleaningliquid cavity 12; the cleaningliquid cavity 12 and the cleaningliquid storage bag 20 The body is communicated through theinjection device 30 ; thedrainage cavity 11 is communicated with thedrainage device 40 ;

本方案中，通过设置疏导装置50，能够清除引流腔体11内凝结的血肿，以便于脑病科用冲洗器正常工作。In this solution, by disposing thedredging device 50, the coagulated hematoma in thedrainage cavity 11 can be removed, so as to facilitate the normal operation of the irrigator for the department of encephalopathy.

具体来说，在脑病科用冲洗器工作时，颅内的血肿会流入引流腔体11内，疏导装置50沿引流腔体11往复滑动时，能够配合引流腔体11的侧壁挤压血肿，或将血肿推出引流腔体11，以实现对引流腔体11内血肿的清除，使脑病科用冲洗器正常工作。Specifically, when the irrigator used in the encephalopathy department works, the intracranial hematoma will flow into thedrainage cavity 11. When thedredging device 50 slides back and forth along thedrainage cavity 11, it can cooperate with the side wall of thedrainage cavity 11 to squeeze the hematoma. Or push the hematoma out of thedrainage cavity 11, so as to realize the removal of the hematoma in thedrainage cavity 11, so that the irrigator for encephalopathy can work normally.

还需指出，本方案中清洗液腔体12和引流腔体11集成设置在冲洗器本体10中，便于减小脑病科冲洗器的体积，方便医务人员操作。It should also be pointed out that in this solution, the cleaningliquid cavity 12 and thedrainage cavity 11 are integrated in theirrigator body 10, which is convenient for reducing the volume of the encephalopathy irrigator and facilitating the operation of medical personnel.

在上述实施例中，优选地，疏导装置50包括：引导杆51，与冲洗器本体10滑动连接；疏导头，固设于引导杆51的远端，其中，引流腔体11为一端开口的柱形腔体，引导杆51沿引流腔体11的轴线往复滑动时，疏导头能经开口移入引流腔体11，或经开口从引流腔体11移出。In the above embodiment, preferably, thedredging device 50 comprises: aguide rod 51, which is slidably connected to theflusher body 10; When theguide rod 51 slides back and forth along the axis of thedrainage cavity 11, the guide head can move into thedrainage cavity 11 through the opening, or move out from thedrainage cavity 11 through the opening.

本方案中，疏导头设于引导杆51上，在引导杆51沿引流腔体11往复滑动时，疏导头能够随引导杆51往复滑动，以通过疏导头与引流腔体11的挤压破碎血肿，或通过疏导头将血肿移出引流腔体11。In this solution, the dredging head is arranged on theguide rod 51 . When theguide rod 51 slides back and forth along thedrainage cavity 11 , the dredging head can slide back and forth with theguide rod 51 to crush the hematoma through the extrusion between the dredging head and thedrainage cavity 11 . , or move the hematoma out of thedrainage cavity 11 through the unblocking head.

还需指出，通过将出液口13设置在冲洗器本体10的侧壁上，且引流腔体11的开口位于冲洗器本体10的端部，能够防止清洗液直接经开口回流至引流强内，以在维持颅压稳定的前提下提高冲洗效率。It should also be pointed out that by arranging theliquid outlet 13 on the side wall of thewasher body 10 and the opening of thedrainage cavity 11 at the end of thewasher body 10, it is possible to prevent the cleaning liquid from directly flowing back into the drainage force through the opening. In order to improve the flushing efficiency on the premise of maintaining the stability of intracranial pressure.

在上述任一实施例中，优选地，引流腔体11的开口位置处设有环形凸起111，环形凸起111沿引流腔体11的径向延伸，由开口向引流腔体11内，环形凸起111的半径先减小后增大。In any of the above embodiments, preferably, anannular protrusion 111 is provided at the opening position of thedrainage cavity 11 , and theannular protrusion 111 extends along the radial direction of thedrainage cavity 11 , from the opening to thedrainage cavity 11 .

本方案中，环形凸起111能配合疏导头挤压血肿，以在开口位置处将血肿破碎，防止较大肿块的血肿进入引流腔内部造成引流腔堵塞。In this solution, theannular protrusion 111 can cooperate with the dredging head to squeeze the hematoma, so as to break the hematoma at the opening position, so as to prevent the hematoma of a larger mass from entering the drainage cavity and causing blockage of the drainage cavity.

在上述任一实施例中，优选地，疏导头包括多个固设于引导杆51远端的疏导筋521，多个疏导筋521沿引导杆51的周向依次排列，其中，由开口向引流腔体11内，疏导筋521与引导杆51在引流腔体11径向上的间距先增大后减小。In any of the above-mentioned embodiments, preferably, the guiding head includes a plurality of guidingribs 521 fixed on the distal end of theguide rod 51 , and the plurality of guidingribs 521 are arranged in sequence along the circumferential direction of the guidingrod 51 . In thecavity 11 , the distance between thedredging ribs 521 and theguide rods 51 in the radial direction of thedrainage cavity 11 first increases and then decreases.

本方案中，疏导筋521对血肿有较强的破碎作用，同时配合环形凸起111的挤压，能够增加血肿破碎效果。In this solution, thedredging ribs 521 have a strong crushing effect on the hematoma, and at the same time cooperate with the extrusion of theannular protrusion 111 to increase the crushing effect of the hematoma.

同时，由开口向引流腔体11内，疏导筋521与引导杆51在引流腔体11径向上的间距先增大后减，这样，在疏导筋521往复穿过环形凸起111的过程中，疏导筋521本身具有导向效果，以能够减小摩擦。同时，还便于引导肿块进入疏导筋521与环形凸起111的间隙内，以对肿块及逆行挤压破碎。At the same time, from the opening to thedrainage cavity 11, the distance between the guidingribs 521 and theguide rods 51 in the radial direction of thedrainage cavity 11 increases first and then decreases. The guidingrib 521 itself has a guiding effect to reduce friction. At the same time, it is also convenient to guide the mass into the gap between thedredging rib 521 and theannular protrusion 111, so as to crush and crush the mass and retrograde.

在上述任一实施例中，优选地，疏导筋521与引导杆51在引流腔体11径向上的最大间距，不小于环形凸起111的最小半径。In any of the above embodiments, preferably, the maximum distance between theguide ribs 521 and theguide rods 51 in the radial direction of thedrainage cavity 11 is not less than the minimum radius of theannular protrusion 111 .

本方案中，疏导筋521与引导杆51在引流腔体11径向上的最大间距，不小于环形凸起111的最小半径。In this solution, the maximum distance between the guidingrib 521 and the guidingrod 51 in the radial direction of thedrainage cavity 11 is not less than the minimum radius of theannular protrusion 111 .

具体来说，在一种可能的实施方式中，疏导筋521与引导杆51在引流腔体11径向上的最大间距，等于环形凸起111的最小半径。Specifically, in a possible implementation manner, the maximum distance between the guidingribs 521 and the guidingrods 51 in the radial direction of thedrainage cavity 11 is equal to the minimum radius of theannular protrusion 111 .

本方案中，当疏导筋521与环形凸起111之间具有血肿时，能够对血肿有较好的挤压效果。In this solution, when there is a hematoma between thedredging rib 521 and theannular protrusion 111, the hematoma can be squeezed better.

在另一种可能的实施方式中，疏导筋521与引导杆51在引流腔体11径向上的最大间距，大于环形凸起111的最小半径。In another possible implementation manner, the maximum distance between the guidingribs 521 and the guidingrods 51 in the radial direction of thedrainage cavity 11 is greater than the minimum radius of theannular protrusion 111 .

本方案中，在疏导筋521穿过环形凸起111时，疏导筋521本身能够向引导杆51一侧形变，这样能够对夹在疏导筋521与引导杆51之间的血肿及逆行挤压，以破碎血肿或将血肿挤出疏导筋521与引导杆51之间的间隙。In this solution, when thedredging rib 521 passes through theannular protrusion 111, thedredging rib 521 itself can be deformed to the side of theguide rod 51, so that the hematoma and retrograde squeezed between thedredging rib 521 and theguide rod 51 can be squeezed. In order to break the hematoma or squeeze the hematoma out of the gap between the guidingrib 521 and theguide rod 51 .

在上述任一实施例中，优选地，疏导筋521远离引导杆51远端的一端设有切削头。In any of the above embodiments, preferably, a cutting head is provided at one end of the guidingrib 521 away from the distal end of theguide rod 51 .

By setting the cutting head, when thedredging rib 521 slides from the opening to the inside of thedrainage cavity 11 , the dredging rib can be cut into thedrainage cavity 11 . The hematoma between 521 and theannular protrusion 111 is broken to prevent thedrainage cavity 11 from being blocked.

同时，由于切削头设置在疏导筋521靠近引流腔体11内部的一侧，能够提高使用的安全性。At the same time, since the cutting head is arranged on the side of thedredging rib 521 close to the inside of thedrainage cavity 11, the safety of use can be improved.
