Novel disposable negative pressure drainage tube

Technical Field

The utility model relates to the field of medical equipment, more specifically the theory that says so, it relates to a novel disposable negative pressure drainage tube.

Background

At present, the traditional surgical drainage is a cylindrical hollow rubber drainage tube in the mainstream. However, the rubber material drainage tube has the problems of low drainage rate, unsmooth drainage, easy concurrent infection, delayed tube drawing and the like due to the problems of easy bending and easy blockage. In recent years, the emerging cross-shaped drainage tube with the side concave groove type solves the problems that the abdominal cavity drainage tube is easy to bend and block, and is popular among abdominal cavity operation doctors in a two-line city. However, in the current thyroid surgery, because the thyroid surgery mostly relates to the characteristics of bilateral total thyroidectomy or secondary total thyroidectomy, double drainage tubes or a common Y-shaped rubber drainage tube are mostly adopted at present. The double drainage tubes are placed, and the defect that two drainage wounds are generated along with tube drawing, so that the attractiveness is affected; meanwhile, both the thyroid gland and the abdominal cavity have the characteristics of easy compression and easy blockage, and particularly, the thyroid gland is positioned at the special position of the neck, so that the available drainage space is much narrower than the abdominal cavity. Therefore, a new drainage tube is urgently needed, the blockage rate of the pipeline can be reduced, the closing of the tube cavity caused by compression can be effectively prevented, and the drainage efficiency is improved.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in figures 1 to 4, the novel disposable negative pressure drainage tube comprises a drainage tube 1, a negative pressure drainage ball 2, a liquid storage bag 3 and a liquid inlet one-way valve 4. The full length of the drainage tube 1 is 16 cm, the drainage tube is Y-shaped, the upper half part of the Y shape is the front end of the drainage tube 1 and is 12 cm in length, and the lower half part of the Y shape is the tail end and is 4 cm in length. The front end of the drainage tube 1 can be bundled into a circular tube. The drainage tube 1 adopts a Y shape, so that the drainage tube is bundled into a circular tube for better fitting the positions of the thyroid glands on the two sides, the storage and the processing are convenient, and the production cost is reduced. It is noted that in the actual manufacturing process, the size of the negative pressure drainage tube including, but not limited to, the above data can be adjusted as needed.

The front end of the drainage tube 1 is of a bilateral semicircular drainage structure, each side adopts a T-shaped groove design, and the side surface of the drainage tube is coated by a film. The film is made of sterile high polymer materials, and is safe and reliable. When the drainage tube is used, the front end of the drainage tube 1 is respectively arranged at the two sides of the thyroid at the two sides, compared with the traditional drainage tube, the double grooves formed in the utility model greatly improve the contact area and the contact length of the wound surface, and effectively avoid paralysis of the whole section of the drainage tube caused by the blockage of a certain section of the drainage tube, thereby improving the drainage efficiency and reducing the related complications such as infection; in addition, the unique T-shaped design greatly improves the stress strength of the local drainage tube, so that the local drainage tube can keep the original shape at the neck with narrow space and is not easy to deform. The front end of the drainage tube 1 is marked with scales, the measuring range of the scales is 0-4.0 cm, and the 0 cm position is the opening end position of the front end of the drainage tube 1; it is noted that the size of the drainage tube 1 and the length of the scale can be adjusted as required. The design of scale is used for the suggestion art person to place the depth position of drainage tube 1, prevents that drainage tube 1's position is incorrect, and is too dark or too shallow, leads to the drainage effect not obvious, even goes wrong. At the scale of 1 cm, the drainage tube 1 is changed into a cylindrical hollow tube from a bilateral semicircular drainage structure; the processing degree of difficulty of two side semi-circular drainage structures is big, consequently is accomplishing drainage work back, and the structure of drainage tube 1 becomes ordinary cylindrical hollow tube, the processing of being convenient for on the one hand, reduction in production cost, on the other hand also be the collection that can be more smooth for the liquid of conveniently drawing forth. The outer diameter of the tail end of the drainage tube 1 is gradually reduced along the axial direction of the drainage tube until the drainage tube is connected with the negative pressure drainage ball 2.

Preferably, the negative pressure drainage ball 2 is elliptical and is arranged at the tail end of the drainage tube 1. The surface of the negative pressure drainage ball 2 is marked with scales, and the measuring range of the scales is 0-4.0 cm. It is worth noting that the size of the negative pressure drainage ball 2 and the length of the scale can be adjusted according to the requirement. The scales can help the operator to judge the drainage effect. The negative pressure drainage ball 2 is provided with a connecting pad which is connected with the tail end of the drainage tube 1. The end of the drainage tube 1 can be matched with any size of drainage ball on the market, thereby reducing the cost. The liquid inlet one-way valve 4 is arranged between the negative pressure drainage ball 2 and the drainage tube 1, and the liquid inlet one-way valve 4 comprises a liquid inlet valve body and a liquid inlet valve core. The liquid inlet valve body is in a step-shaped cylindrical shape, the diameter of the front end cylindrical shape is matched with the inner diameter of the drainage tube 1, and the front end cylindrical shape is embedded in the drainage tube 1; a part of the rear end cylinder is embedded in the negative pressure drainage ball 2. The design ensures the connection strength of the liquid inlet one-way valve 4 and the negative pressure drainage ball 2. The liquid inlet one-way valve 4 is fixedly connected with the negative pressure drainage ball 2 in a non-detachable mode, so that the sealing performance is ensured, and the pollution to the inside of a pipeline is prevented. The liquid inlet valve body is hollowed, and the liquid inlet valve core is arranged at the hollowed part of the liquid inlet valve body; the liquid inlet valve core controls the on-off state of the flow channel of the liquid inlet valve body. The liquid storage bag 3 is connected with the negative pressure drainage ball through a liquid discharge pipe, and the connection mode is a detachable structure, so that the disassembly and the replacement are convenient; the liquid discharging one-way valve is arranged in the liquid discharging pipe. The liquid inlet one-way valve 4 and the liquid discharge one-way valve ensure that the extracted tissue fluid cannot flow backwards, and the safety is improved. The liquid storage bag 3 can effectively store tissue liquid, and is convenient to collect and treat.

Preferably, the drainage tube 1 is made of medical grade polyvinyl alcohol material, but not limited to the material, the medical grade polyvinyl alcohol material has high reliability, good safety, stable chemical and physical properties, better flexibility and strength, and can prevent the tube cavity from being closed due to pressure, thereby improving the whole drainage efficiency.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the concept of the present invention, and these improvements and decorations should also be considered as the protection scope of the present invention.
