Abstract
The utility model discloses a prevent pulling drainage tube, including drainage tube main part, entrance point and interface end are located the both ends of drainage tube main part, the water conservancy diversion hole has been seted up in the drainage tube main part, the water conservancy diversion hole is the narrow outer wide wedge hole in, water conservancy diversion hole equipartition is in the drainage tube main part. The longitudinal section angle of the inner wall of the flow guide hole is 45-75 degrees. The utility model has the advantages that: because set up the honeycomb duct into the wedge, inside narrow outside is wide promptly for when the drainage tube was taken out after the use, the disease health tissue that imbeds inside the honeycomb duct can very smooth-going roll-off water conservancy diversion hole, can not take place to drag, has avoided the tissue to pull to cause the harm to the disease.
Description
Technical Field
The utility model relates to a medical instrument, in particular to a strain-prevention drainage tube.
Background
The drainage tube is a medical appliance for clinical surgery drainage, which guides pus, blood and liquid accumulated in human tissues or body cavities to the outside of the body, prevents postoperative infection and promotes wound healing. Has wide application in various surgical operations including medical operations. However, the drainage tube needs to be taken out after being used, the guide holes on the drainage tube in the prior art are vertical holes, and after the drainage tube is inserted into the surgical position of a patient, some tissues enter the guide holes due to the outward tension of human tissues, and the tissues are pulled to be injured when the drainage tube is taken out, so that the injury to the patient is caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a can effectually avoid pulling the drainage tube of preventing pulling that sick health tissue pulled when taking out the drainage tube.
In order to solve the technical problem, the utility model discloses a technical scheme does: the utility model provides a prevent pulling drainage tube, includes drainage tube main part, entrance point and interface end are located the both ends of drainage tube main part, the water conservancy diversion hole has been seted up in the drainage tube main part, the water conservancy diversion hole is the outer wide wedge hole of interior narrow, water conservancy diversion hole equipartition is in the drainage tube main part.
Preferably, the longitudinal section angle of the inner wall of the diversion hole is 45-75 degrees.
Preferably, the longitudinal section angle of the inner wall of the diversion hole is 45 degrees.
Preferably, the longitudinal section angle of the inner wall of the diversion hole is 50 degrees.
Preferably, the longitudinal section angle of the inner wall of the diversion hole is 75 degrees.
Preferably, the surface of the drainage tube body is provided with length scale marks.
Preferably, the joint of the mouth joint end and the drainage tube body is connected with a negative pressure tube, and the negative pressure tube is communicated with the drainage tube body.
Adopt above-mentioned technical scheme, owing to set up the honeycomb duct into the wedge, inside narrow outside is wide promptly for when the drainage tube was taken out after the use, the disease health tissue that is embedded into honeycomb duct inside can very smooth-going roll-off water conservancy diversion hole, can not take place to drag, has avoided the tissue to pull and has led to the fact the harm to the disease.
Drawings
Fig. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic view of a cross-sectional structure of the flow guide hole in the present invention.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Referring to fig. 1 and 2, the present embodiment discloses a strain-prevention drainage tube, which includes a drainage tube main body 1, an inlet end 3 and a connector end 4, wherein the inlet end 3 and the connector end 4 are located at two ends of the drainage tube main body 1, a flow guide hole 11 is formed in the drainage tube main body 1, the flow guide hole 11 is a wedge-shaped hole with a narrow inner part and a wide outer part, and the flow guide holes 11 are uniformly distributed in the drainage tube main body 1.
Preferably, the longitudinal section angle of the inner wall of the diversion hole 11 is 45-75 degrees, and the specific angle also needs to be set by referring to the thickness of the pipe wall.
Preferably, the longitudinal section angle of the inner wall of the diversion hole 11 is 45 degrees, and under the angle, the processing difficulty and the vertical shearing force are moderate. In other embodiments of the present invention, the longitudinal section angle of the inner wall of the diversion hole 11 may also be 50 °. It is feasible that the longitudinal section angle of the inner wall of the diversion hole 11 may also be 75 °.
Preferably, drainage tube main part 1 surface is provided with length scale mark 2, sets up the scale mark, can make things convenient for medical personnel to the control male degree of depth to better nursing the operation.
Feasible, in the utility model discloses another embodiment, mouth-piece 4 is connected with negative pressure pipe 5 with drainage tube body 1 junction, negative pressure pipe 5 communicates with drainage tube body 1. The negative pressure tube 5 may be formed integrally with the drainage tube body 1 or formed by thermal bonding. Of course, the negative pressure tube 5 may be a tube body similar to the mouthpiece end, and negative pressure drainage is formed by inhaling air through a balloon or the like. Because set up the honeycomb duct into the wedge, inside narrow outside is wide promptly for when the drainage tube was taken out after the use, the disease health tissue that imbeds inside the honeycomb duct can very smooth-going roll-off water conservancy diversion hole, can not take place to drag, has avoided the tissue to pull to cause the harm to the disease.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
