Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, the present invention will now be described.

As shown in fig. 1, the abdominal cavity drainage tube capable of being manually thinned according to the embodiment of the present invention comprises:

an inner pipe 1 and an outer pipe 2 connected with the inner pipe;

the inner tube 1 is provided with a drainage cavity 10 for collecting postoperative oozing blood and oozing liquid; the drainage cavity 10 is used for collecting postoperative oozing blood and oozing liquid; two ends of the drainage cavity 10 are open structures;

the outer pipe 2 is enclosed outside the inner pipe 1;

the peritoneal drainage tube that can manually attenuate still includes: a telescopic cavity 20 arranged between the inner tube 1 and the outer tube 2, and a piston structure arranged outside the outer tube 2 and connected with the telescopic cavity 20;

the telescoping lumen 20 is closed at both ends, and the extracorporeal piston structure, which may be, for example, a structure similar to the tail of a catheter, is normally occluded,

the telescopic cavity 20 is provided with a space for accommodating sterile normal saline, and the piston structure is used for extracting and injecting the normal saline, so that the telescopic cavity 20 can be expanded and reduced. Bellows 20 contains sterile saline to prevent fluid in bellows 20 from flowing into the abdominal cavity and causing infection. At the same time, the bellows chamber 20 is not filled with air to avoid filling with air causing rupture, possibly causing damage.

The drainage tube is filled with water before the drainage tube is placed into a human body, and the patient is anaesthetized and does not know pain when the tube is placed into the drainage tube, so the thickness of the drainage tube is irrelevant. However, no anesthesia is performed during tube drawing, so that the whole drainage tube becomes thin after the physiological saline in the telescopic cavity 20 is pumped out, the friction is reduced after the drainage tube is drawn out, and the pain of a patient is relieved.

Further, the telescopic cavity 20 is of an annular structure, such as a circular ring, two ends of the telescopic cavity 20 are closed, and two ends of the inner tube 1 and two ends of the outer tube 2 are connected through an annular connecting end 7 to form a whole. The materials of the inner pipe 1 and the outer pipe 2 are latex, for example, the material of the inner pipe 1 is harder than that of the outer pipe 2, so that the inner pipe 1 cannot be collapsed during water injection; the annular connecting end 7 is, for example, a circular latex sheet or a silicon sheet, and is used for connecting (bonding) the inner tube 1 and the outer tube 2 and sealing the telescopic cavity 20;

further, the manually tapered peritoneal drainage tube further comprises: and the lateral seepage hole 3 is arranged in the lateral direction of the outer pipe 2, and the lateral seepage hole 3 extends into the drainage cavity from the outer pipe and is isolated from the telescopic cavity. The lateral seepage holes 3 are convenient for nearby seepage blood to flow into the drainage cavity 10, and are convenient for seepage blood and seepage liquid to be discharged;

furthermore, the number of the lateral seepage holes 3 is multiple, so that the discharging effect of the seepage and the seepage is better. The lateral seepage holes 3 can be arranged in plurality from top to bottom so as to facilitate the discharge of seepage and seepage fluid.

Further, the piston structure includes: a piston tube 4 connected outside the outer tube 2, and an elastic sealing piston 5 arranged in the piston tube, wherein the piston tube 4 is communicated with the telescopic cavity 20. The elastic sealing piston 5 can be a rubber plug which plays a sealing role at ordinary times and can form a channel for extracting and injecting the physiological saline when needed.

Further, the peritoneal drainage tube that can be thinned manually still includes: a syringe (not shown) capable of entering and exiting said elastic sealing piston 5. The physiological saline can be conveniently extracted and injected through the syringe.

Furthermore, two ends of the abdominal cavity drainage tube which can be manually thinned are divided into an inner end (the upper end in figure 1) and an outer end (the lower end in figure 1), the inner end is used for extending into a human body, the outer end is exposed out of the human body, and the inner end is in a shape of a symmetrical circular arc which is sunken towards the outer end, namely a fish mouth shape or a fish mouth shape, so that peripheral oozing blood is easily collected.

Further, the maximum outer diameter of the outer tube after the saline injection was 16mm, and the minimum outer diameter of the outer tube (after the contraction of the outer tube after the saline extraction) was 8 mm. Thus, the contraction of the outer tube for extracting the physiological saline can be obvious that the drainage tube with the diameter of 8mm becomes thin.

Further, the piston tube 4 is also made of latex and is of an integrated structure with the outer tube, so that the piston tube is convenient to manufacture. The piston tube 4 has an inner diameter mm and an outer diameter corresponding to those of a 20ml syringe, respectively, so as to be manufactured and used in cooperation with the syringe.

After the abdominal operation is finished, if a drainage tube is required to be placed, the drainage tube can be placed at a proper position. After the patient recovers well after operation, the drainage tube can be pulled out, a doctor firstly uses an injector to pump out the sterile normal saline in the telescopic cavity 20, the drainage tube is observed to be thinned, the outer tube wall is attached to the inner tube wall, and then the drainage tube is slowly pulled out of the body. Thus, the extraction process and skin incision are less abrasive and less painful for the patient.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. For the utility model discloses a each component can make up each other under the condition of conflict not, and any technical personnel in the field do not deviate from the utility model discloses an equal change and the modification made under the prerequisite of the design and principle all should belong to the scope of protection of the utility model.
