Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a peritoneal negative pressure flushing drainage tube. Background Art
[0002] A drainage tube is a medical device used for clinical surgical drainage. It guides the pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for urinary catheterization, some are used for wounds, and are used in the chest cavity, brain cavity, gastrointestinal tract, bile duct, etc. The purpose of surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing.
[0003] However, when the abdominal negative pressure flushing drainage tube is in use, the inner part of the drainage tube is often hollow, and the flow rate of the drainage fluid in the drainage tube is not well regulated. As a result, when the patient is given drainage treatment through the drainage tube, the flow rate of the drainage fluid is slow, which affects the timeliness of the drainage treatment for the patient and increases the patient's recovery period.
[0004] Therefore, in view of this, the existing structural deficiencies were studied and improved, and a peritoneal negative pressure flushing drainage tube was proposed. Utility Model Content
[0005] The utility model aims to provide a peritoneal negative pressure flushing drainage tube to solve the problem of low flow rate regulation effect of drainage liquid in the drainage tube proposed in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an abdominal negative pressure flushing drainage tube, comprising a drainage tube body, a connecting negative pressure tube is arranged inside the drainage tube body, a main pipe connection port for connecting a drainage bag is opened on the top of the drainage tube body, the connecting negative pressure tube is spirally arranged on the inner wall of the drainage tube body, a flow port located between the spirals of the connecting negative pressure tube is opened on the inner wall of the drainage tube body, and a connecting port is opened on the surface of the connecting negative pressure tube.
[0007] Furthermore, a water injection pipe is fixedly connected to the inner wall of the drainage tube body.
[0008] Furthermore, the outer wall contour of the connection port is smaller than the outer wall contour of the flow port.
[0009] Furthermore, the outer wall profile of the water injection pipe is arranged in a straight line.
[0010] Compared with the prior art, the beneficial effects of the utility model are:
[0011] The utility model is connected to the setting of the negative pressure tube. When the drainage tube is used to treat the patient, in order to increase the speed of the drainage tube for drainage treatment of the patient, the negative pressure tube is connected in a spiral shape, so that the drainage liquid is transported in a spiral shape, and the flow port and the connecting port are opened to increase the drainage amount of the drainage tube, prevent the drainage liquid from flowing too fast and splashing, and achieve the effect of improving the stability of the drainage tube for drainage treatment of the patient.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Embodiment 1: Figure 1-Figure 3 As shown, the abdominal negative pressure flushing drainage tube includes a drainage tube body 1, a negative pressure tube 2 is connected inside the drainage tube body 1, a main pipe connection port 3 for connecting a drainage bag is provided on the top of the drainage tube body 1, the negative pressure tube 2 is spirally arranged on the inner wall of the drainage tube body 1, a flow port 5 located between the spirals of the negative pressure tube 2 is provided on the inner wall of the drainage tube body 1, and a connecting port 6 is provided on the surface of the negative pressure tube 2.
[0019] Furthermore, the negative pressure tube 2 is connected to the inner wall of the drainage tube body 1 in a spiral shape, which is beneficial to increase the flow rate of the drainage liquid.
[0020] Furthermore, the outer wall contour of the connection port 6 is smaller than the outer wall contour of the flow port 5, which is beneficial for increasing the drainage volume of the drainage tube through the opening of the connection port 6.
[0021] Embodiment 2: Figure 1 , Figure 2 and Figure 4 As shown, the abdominal negative pressure flushing drainage tube proposed by the utility model, compared with the first embodiment, as another embodiment of the utility model, the inner wall of the drainage tube body 1 is fixedly connected with a water injection tube 4. When working, by setting the connection negative pressure tube 2, it is beneficial when the drainage tube is used to treat the patient. In order to increase the speed of drainage treatment of the patient by the drainage tube, the negative pressure tube 2 is connected in a spiral shape, so that the drainage liquid is transported in a spiral shape, and through the opening of the flow port 5 and the connecting port 6, the drainage amount of the drainage tube is increased, and the drainage liquid flow rate is prevented from being too fast and splashing, thereby achieving the effect of improving the stability of drainage treatment of the patient by the drainage tube.
[0022] Furthermore, the outer wall profile of the water injection pipe 4 is arranged in a straight line, which is conducive to the convenient increase of water flow.
[0023] Working principle: When using the abdominal negative pressure flushing drainage tube, first, connect the main connecting port 3 and the drainage bag normally, and when using the drainage tube to treat the patient, in order to increase the speed of drainage treatment of the patient by the drainage tube, the negative pressure tube 2 is connected in a spiral shape so that the drainage liquid is transported in a spiral shape, and through the opening of the flow port 5 and the connecting port 6, the drainage amount of the drainage tube is increased, and the drainage liquid flow rate is prevented from being too fast and splashing, thereby achieving the effect of improving the stability of the drainage treatment of the patient by the drainage tube.
