Description

Technical Field

[0001] The invention relates to a drainage catheter, in particular to a catheter drainage component for drug or food poisoning. Background Art

[0002] Drainage tubes are commonly used medical equipment in clinical surgery. Patients in thoracic surgery, respiratory medicine and oncology often have pleural effusion, peritoneal effusion or pneumothorax, or some people have accidentally ingested toxic drugs or food and need gastric lavage. At this time, it is necessary to use a drainage tube using the siphon or negative pressure suction principle, placed in the human surgical area or body cavity and passed through the skin incision to drain the pus, exuded blood, tissue fluid and other toxic fluids accumulated between human tissues or in the body cavity to the outside of the body, thereby promoting wound healing and disease recovery.

[0003] The existing catheter drainage devices have weak guidance, and the directional guide wire is inside the catheter. Especially when draining poisoned food residues, the directional guide wire inside the catheter affects the outflow of poisonous food. Time is life. Draining the poisonous substances in the stomach as soon as possible can improve the treatment effect. Some catheters have poor directional control and cannot suck out the food residues at the bottom of the stomach, affecting the treatment of patients.

[0004] Therefore, how to provide a catheter drainage component with strong guidance and can quickly suck out toxic food or drugs in the stomach is a problem that technical personnel in this field urgently need to solve. Summary of the invention

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See the attached Figures 1 to 5 According to an embodiment of the present invention, a catheter drainage assembly for drug or food poisoning includes:

[0028] A catheter body 1, the catheter body 1 includes an introduction end 101 and an outflow end 102, and a plurality of drainage holes 2 are provided on the outer wall of the introduction end 101; guide wire perforations 3 are provided in opposite side walls of the catheter body 1, respectively, and the guide wire perforations are located inside the side walls of the catheter body, and the directional guide wire can slide relatively in the guide wire perforations, and the guide wire perforations 3 correspond to the axial direction of the catheter body 1, and a guide wire groove 4 is provided on the outer wall of the catheter body 1, one end of the guide wire groove 4 is connected to the guide wire perforations 3, and the other end of the guide wire groove 4 extends to the edge of the introduction end 101;

[0029] Directional guide wires 5, which are divided into two groups. One end of the directional guide wires 5 passes through the guide wire perforation 3 and is fixedly connected to the other end of the guide wire groove 4. The other end of the directional guide wires 5 is located outside the catheter body 1.

[0030] The shield 6 is fixed on the catheter body 1, and the shield 6 is adapted to be embedded in the patient's mouth and maintain the patient's mouth in an open state, thereby ensuring the normal drainage.

[0031] The adapter 7 is fixed to the outflow end 102, and the piston cylinder 8 is detachably connected to the adapter 7. The edge of the catheter body 1 corresponding to the outflow end 102 is connected to a drainage tube 9 and an injection tube 10. The drainage tube drains the toxic drugs or food in the stomach, and the injection tube can inject clean water and medical drugs.

[0032] In other embodiments, the axial length of the guide wire perforation 3 is greater than the length of the guide wire groove 4. That is, most of the directional guide wire is in the guide wire perforation, and a small part is in the guide wire groove, ensuring that the directional guide wire is smoothly reset to the guide wire groove during reversal control. The directional guide wire is a platinum directional guide wire with a certain strength and hardness.

[0033] In other specific embodiments, a fixing groove is provided on the side wall of the catheter body 1 corresponding to the other end of the guide wire groove 4, and a ball head 11 is fixedly connected to one end of the directional guide wire 5, and the ball head 11 is adapted and fixed in the fixing groove.

[0034] In other embodiments, the cross section of the guide wire groove 4 is U-shaped, and the groove depth of the guide wire groove 4 is equal to the diameter of the directional guide wire. This facilitates the resetting of the directional guide wire. When the directional catheter is a straight tube, the directional guide wire is relocated in the guide wire groove, further expanding the inner diameter of the directional catheter, which facilitates drainage.

[0035] Specifically, the ends of the drainage tube 9 and the injection tube 10 are detachably connected with sealing caps to ensure a sealed state when not in use and to keep the drainage tube and the injection tube hygienic.

[0036] In some other embodiments, the adapter 7 is a circular sleeve structure, a snap-in flange 13 is provided on the inner wall of the adapter 7, the piston cylinder 8 includes a cylinder body 801 and a suction piston 802, the suction piston 802 is slidably connected to the inside of the cylinder body 801, and a snap-in groove 14 is provided on the bottom edge of the outer wall of the cylinder body 801, and the snap-in flange 13 is adapted to snap-in with the snap-in groove 14.

[0037] In some other specific embodiments, a branch pipe 15 is connected to the outer wall of the cylinder 801 , the branch pipe 15 is communicated with the interior of the cylinder 801 , and a branch pipe valve 16 is connected to the branch pipe 15 .

[0038] In some other embodiments, an end of the catheter body 1 close to the adapter 7 is connected to an air intake valve 17. The air intake valve controls the overall air intake effect of the catheter body.

[0039] Specifically, the other end of the direction guide wire 5 is fixedly connected with a pull ring 18 to facilitate pulling the direction guide wire.

[0040] When the present invention is used, the patient's mouth is opened, and the catheter body is inserted from the mouth into the stomach. First, part of the gas is injected into the stomach with a piston cylinder so that there is a certain air pressure in the stomach to facilitate subsequent drainage. Physiological saline and digestive medicine are injected with a syringe, and suction is performed with the piston cylinder until liquid flows out of the drainage tube. At this time, the direction guide wire is controlled to adjust the position of the end of the catheter body in the stomach to ensure clean suction, and clean water or physiological saline is injected again. Suction is repeated until clean liquid flows out, and gastric lavage is completed.

[0041] As for the device and the method of use disclosed in the embodiment, since they correspond to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0042] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
