Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3, the negative pressure suction device of the present embodiment mainly includes a negative pressure ball 1, a connecting pipe 2 and a suction pipe 3, wherein the negative pressure ball 1 is provided with a connecting port 401, and is communicated with the connecting pipe 2 through the connecting port 401, and the connecting pipe 2 is further communicated with the suction pipe 3. The negative pressure ball 1 is a medical elastic hollow plastic ball, has an ellipsoidal shape and a storage capacity of about 100ml, and is mainly used for providing negative pressure suction force, so that the negative pressure ball 1 is further required to be provided with a discharge port 409 for discharging air and liquid, the discharge port 409 and the connection port 401 are respectively positioned at two opposite ends of the negative pressure ball 1, and in order to seal the discharge port 409, a plug 410 is further arranged on the negative pressure ball 1, and the plug 410 is detachably sealed in the discharge port 409. The connecting pipe 2 is a medical hollow hard pipe body, such as a PVC plastic pipe, and is mainly used for connecting the negative pressure ball 1 and the suction pipe 3; the suction tube 3 is a medical hollow soft tube body and is mainly used for sucking wound seepage, the tube diameter of the suction tube is provided with multiple specifications of 2mm, 4mm and the like, and the tube diameter of the multiple specifications can be used for drainage of wounds with different sizes. The port of the suction tube 3 far away from one end of the connecting tube is a suction port 403, and wound seepage can enter the suction tube 3 from the suction port 403 and then enter the negative pressure ball 1 through the connecting tube 2.

When the device is used, the suction port 403 of the suction tube 3 is placed near the wound, and the suction tube 3 is fixed by medical glue; opening the plug 410, squeezing the negative pressure ball 1 to deform, in the deformation process, the internal space of the negative pressure ball 1 becomes small and causes the internal air to be discharged from the discharge port 409, after squeezing to a certain extent, the plug 410 is plugged into the discharge port 409 again to seal the discharge port 409, therefore, the negative pressure ball 1 has only one air inlet or liquid inlet channel, namely: suction port 403-suction tube 3-connecting tube 2-connecting port 401-negative pressure ball 1; the negative pressure ball 1 gradually returns to the original state under the action of the elastic force of the negative pressure ball, negative pressure suction or imbibition operation is carried out, and seepage flowing out from the wound can enter from the suction port 403 under the action of the negative pressure suction and finally reach the inside of the negative pressure ball 1, and the seepage suction work is completed through the negative pressure. To reduce the suction port 403 from sucking to the human body, the probability of clogging is reduced, and the opening of the suction port 403 is set to an arc-shaped oblique angle of concave. Because the storage capacity of the saccule is about 100ml, and the diameter of the suction port 403 is not large, the feeding amount is not large, and the general drainage liquid for the in-ear operation is small, and the drainage can be kept for about 24 hours through practical verification; of course, if the diversion volume is too large, the plug 410 may be opened to pour out the permeate from the discharge port 409 or to replace a new negative pressure ball 1.

When the amount of seepage is small, only one suction port 403 is used for sucking seepage basically, but if the amount of seepage is large, more inlets are needed, so that a plurality of side suction ports 402 are arranged at one end of the suction pipe 3 close to the suction port 403, and the side suction ports 402 are designed to be convenient for absorbing seepage in multiple directions.

In order to facilitate the fixing of the device, a hook 412 is connected to the side wall of the negative pressure ball 1. When a patient stands or goes out, the negative pressure ball 1 can be hung on clothes, a wall or an infusion support by the hook 412, and the patient does not need to be held by hands, so that convenience is improved.

The negative pressure ball 1 is kept at a low position, so that the backflow of seepage can be prevented, but under certain activity scenes (such as pouring out seepage) or carelessly, the negative pressure ball 1 can be possibly caused to be at a high position, in order to effectively prevent the backflow of seepage, a water stop clamp 422 can be arranged on the connecting pipe 2, and the structure of the water stop clamp 422 is the same as or similar to that of a common infusion tube water stop clamp.

Referring to fig. 2 and 3, the side wall of the connecting pipe 2 is communicated with a gas release pipe 405, a plug 406 extending to the outer wall of the gas release pipe 405 is arranged on the inner wall of the gas release pipe 405, and a pull ring 407 is fixedly connected to the outer wall of the plug 406 in an adhesive manner. The inner wall of the air leakage pipe 405 is provided with a sliding groove 411, the side wall of the plug 406 is provided with a sliding block 408, and the sliding block 408 is movably connected in the sliding groove 411.

In this embodiment: when the suction force of the side suction port 402 and the suction port 403 is too large, the side suction port 402 or the suction port 403 may suck the skin mucosa, so that drainage at the hole is not smooth, and pain is caused to a patient when the skin mucosa is hard pulled, so that skin mucosa is damaged, at this time, an outward pulling force can be given to the pull ring 407, so that the pull ring 407 drives the plug 406 and the slide block 408 to move along the chute 411 of the air release pipe 405, a port inclined surface part of the plug 406 gradually moves out of a lower half port of the air release pipe 405, the air outlet amount of the air release pipe 405 is controlled by adjusting the moving distance of the plug 406, external air enters the suction pipe body, the internal negative pressure of the suction pipe body is reduced, and after the negative pressure disappears, the side suction port 402 or the top suction port 403 can be easily separated from the skin mucosa.

The cross section of the plug 406 is in a right trapezoid shape, so that the air leakage is conveniently controlled by adjusting and controlling the insertion depth of the plug.

The suction tube 3 is further provided with a Y-shaped connector 404 communicated with the suction tube, and the Y-shaped connector 404 is mainly used for conveniently flushing wounds, and the embodiment adopts rubber materials, so that the rubber materials are good in toughness and beneficial to repeated use. When the wound is required to be washed, the connecting pipe is clamped by the water stop clamp 422, the Y-shaped joint 404 is connected by the scalp needle interface, then washing liquid is injected, the washing liquid is discharged from the side suction port 402 and the suction port 403 of the suction pipe 3, the wound is washed, and the washed liquid naturally flows out and is received by the external basin. Irrigation of wounds is a special procedure in special situations.
