Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically an anti extrusion type negative pressure drainage device.
Background
The traditional negative pressure drainage device is generally placed into a part needing drainage under the direct vision of an operator by adopting a plastic hose. The tail end of the negative pressure drainage device is connected with a drainage bag in order to discharge exuded liquid in and after operation out of the body, so as to rapidly remove the exuded liquid in the operation and reduce the risks of infection and blood loss. However, the conventional drainage tube has obvious defects, such as that the conventional negative pressure drainage ball lacks a support structure for resisting extrusion, and is easy to generate a backflow problem when being subjected to external pressure in use, or the backflow and overflow of liquid can be caused by careless operation. Such spillage is quite dangerous if it is for infectious exudates.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1-3, the present invention provides a technical solution:
the utility model provides an anti extrusion type negative pressure drainage device, includes negative pressure sacculus 1, and the outside of the spheroid shell of negative pressure sacculus 1 is equipped with support shell 2, and 1 upper portion of negative pressure sacculus is equipped with negative pressure sacculus joint 12, is equipped with porous pipeline 11 and negative pressure sacculus import 121 on the negative pressure sacculus joint 12, and negative pressure sacculus import 121 passes through silica gel pipe 3 and connects drainage tube 4, and 1 lower part exit of negative pressure sacculus is equipped with flowing back valve 22, and flowing back valve 22 passes through silica gel pipe 3 and connects the stock solution bag 5.
A backflow stopping channel 13 is arranged in the negative pressure balloon joint 12 corresponding to the negative pressure balloon inlet 121, the backflow stopping channel 13 is a channel with a thin upper part and a wide lower part, a blocking ball 131 is arranged in the backflow stopping channel 13, and the diameter of the blocking ball 131 is smaller than the diameter of the lower part of the backflow stopping channel 13 and larger than the diameter of the negative pressure balloon inlet 121.
When the flow rate of the liquid is increased rapidly due to overlarge negative pressure, the liquid needs to be blocked to the channel 13 through backflow in the process of entering the negative pressure balloon 1, and the flow rate and the pressure can be buffered due to the fact that the backflow is blocked to the narrow upper part and the wide lower part of the channel 13; when backflow occurs, the blocking ball 131 is pushed to the negative pressure balloon inlet 121 by the backflow liquid at the first time, and the blocking ball 131 blocks the negative pressure balloon inlet 121 to prevent backflow. During normal negative pressure suction, the check ball 131 is pushed to the bottom of the backflow stop channel 13 by the liquid, and the backflow stop channel 13 has a larger diameter than the check ball 131, so that normal negative pressure suction is not hindered.
Specifically, a plurality of drainage holes are arranged on the drainage tube 4, and the connecting end surface of the drainage tube 4 is a cross tube opening 41. The cross pipe orifice 41 can buffer overlarge negative pressure, so that the injury of tissues or organs in a body caused by the overlarge negative pressure at the wound surface position is avoided. The drainage hole can effectively prevent the membranous substance at the wound surface from blocking the catheter.
Furthermore, a fixing buckle can be additionally arranged at the joint of the silica gel catheter 3 and the negative pressure balloon 1. Or through fixing means such as medical adhesive plaster, the design does not have hard requirements.
The foregoing shows and describes the general principles, essential features, and advantages of the invention.
