Description

Technical Field

[0001] The utility model relates to the field of medical nursing, in particular to a drainage device. Background Art

[0002] There are many types of surgical drainage tubes used clinically, some are used for urinary catheterization, and some are used for wounds, gastrointestinal tract, bile duct, etc. The purpose of surgical drainage is to guide the pus, blood, and fluid accumulated between human tissues or in the body cavity to the outside of the body to prevent postoperative infection and affect wound healing. When patients use drainage tubes, they must pay attention to care. Under normal circumstances, the tissue fluid or blood drained from the patient's body will appear more at the beginning and then gradually decrease. After some intestinal surgeries, the tissue waste fluid or blood in the abdominal cavity is guided out through the drainage tube. However, after intestinal surgery, there is a certain probability that the intestine is damaged or sutured poorly. At this time, feces in the intestine will enter the abdominal cavity and enter the drainage tube under the action of suction force. The feces in the intestine is easy to block the drainage tube. On the outside, the drainage tube is wrapped with tape because it needs to be fixed, which makes it difficult to observe the blockage, which has an adverse effect on the patient's recovery. In view of the existing problems, a drainage device is proposed. Utility Model Content

[0003] The utility model aims to provide a drainage device to solve the problem in the prior art that the drainage tube is wrapped with adhesive tape due to the need for fixation, which makes it difficult to observe the blockage situation.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example 1

[0021] Reference Figure 1-4 A drainage device includes a covering cover 1, which is a transparent cover body. A discharge hole is opened at the bottom of the covering cover 1. A drainage tube 2 is fixedly installed in the discharge hole. The drainage tube 2 is a flexible tube body. A liquid storage bag 3 is fixedly installed at the lower end of the drainage tube 2. The liquid storage bag 3 is a transparent bag body. The liquid storage bag 3 is used to store waste liquid such as tissue blood and water drained from the patient's body, which is beneficial to the patient's recovery. A fixing frame 4 is fixedly installed on the inside of the covering cover 1. A catheter 5 is inserted in the fixing frame 4. The fixing frame 4 is used to limit the catheter 5. An annular adhesive tape 7 is pasted on the edge of the covering cover 1.

[0022] By tightly fitting the cover 1 to cover the outside of the patient's drainage stoma, and by means of a fixing frame 4 fixedly connected thereto, the catheter 5 inserted into the drainage stoma is limited and fixed. At this time, under the influence of the negative pressure suction in the liquid storage bag 3, tissue fluid and other substances in the patient's abdominal cavity are sucked into the cover 1 through the catheter 5. The discharge of tissue fluid and other substances in the catheter 5 can be clearly observed through the transparent cover 1, and it can be judged in time whether there is blockage, which is helpful for judging the patient's intra-abdominal postoperative recovery. At the same time, the fixation of the catheter 5 is more stable, avoiding the negative impact of the catheter 5 slipping on the patient.

[0023] A limiting ring is provided on the fixed sleeve at the outer end of the catheter 5, and a retaining tooth 6 is fixedly installed in a circumferential array on one side of the fixing frame 4 close to the drainage tube 2. The retaining tooth 6 is arranged to abut against the limiting ring. The retaining tooth 6 is arranged to prevent the catheter 5 from slipping into the patient's abdominal cavity, and the retaining tooth 6 has a certain deformation ability, which makes it easier for the catheter 5 to be inserted into the center of the fixing frame 4 and the retaining tooth 6 during installation. A storage shell 8 is fixedly installed on the edge of the covering cover 1, and a sealing strip 9 is clamped in the storage shell 8. The setting of the sealing strip 9 can form a closed and isolated environment on the outside of the patient's drainage stoma. On the one hand, it can prevent bacteria from entering, and on the other hand, it can also effectively prevent the leakage of tissue fluid, blood, etc.

[0024] The lower end of the liquid storage bag 3 is connected to a discharge pipe 12 fixedly installed, and a plastic rotary valve is installed on the discharge pipe 12. The discharge pipe 12 and the plastic rotary valve are both for the convenience of pouring the tissue fluid and blood in the liquid storage bag 3 into a specified area. Hooks 13 are fixedly installed on both sides of the liquid storage bag 3. The hooks 13 facilitate hanging the liquid storage bag 3 on one side of the bed to facilitate fixation and avoid movement.

[0025] Example 2

[0026] According to Example 1, the discharge of tissue fluid and other substances in the catheter 5 can be clearly observed through the transparent cover 1. However, when the tissue fluid or blood water decreases abnormally, it is impossible to determine whether the tissue fluid or blood water is actually reduced or the catheter 5 is blocked. Figure 1-4 , as another preferred embodiment of the utility model, based on embodiment 1;

[0027] An outlet tube 10 is fixedly installed at the center of the outer side of the covering cover 1. The outer end of the outlet tube 10 is bent vertically upward, and the outer end of the outlet tube 10 is threadedly connected to an air bag 11. The air bag 11 is made of flexible material. During the drainage process of using the present device, once it is found that the discharge of tissue fluid from the catheter 5 is abnormally reduced, the outlet tube 10 and the air bag 11 can be used first. By pinching the air bag 11, the air inside is discharged through the one-way valve at the upper end of the air bag 11, making the interior vacuum. At this time, the air bag 11 is released to auxiliaryly suck the tissue fluid and other debris in the catheter 5 into the covering cover 1, so that the cause of the blockage can be quickly observed to see whether there is a blood clot or feces discharge blockage caused by internal organ damage or bleeding, and medical response can be taken in advance to avoid further deterioration of the patient's condition.

[0028] Working principle: When using the device, first insert the catheter 5 into the patient's drainage stoma to connect the abdominal cavity so that the tissue fluid or blood in the abdominal cavity can be discharged. At this time, the outer end of the catheter 5 is inserted into the fixing frame 4. By setting the anti-retraction teeth 6, the catheter 5 is prevented from sliding into the patient's abdominal cavity. The anti-retraction teeth 6 have a certain deformation ability, which makes it easier for the catheter 5 to be inserted into the center of the fixing frame 4 and the anti-retraction teeth 6 during installation. Then, the covering cover 1 is tightly fitted to cover the outside of the patient's drainage stoma, and the annular adhesive patch 7 is attached to the outside of the patient's skin. When affected by the negative pressure suction in the liquid storage bag 3, the patient's abdominal The tissue fluid and other substances in the cavity are sucked into the covering cover 1 through the catheter 5. The discharge of the tissue fluid and other substances in the catheter 5 can be clearly observed through the transparent covering cover 1, and whether there is a blockage can be determined in time. Once it is found that the discharge of tissue fluid from the catheter 5 is abnormally reduced, the lead-out tube 10 and the air bag 11 can be used first. By pinching the air bag 11, the air inside is discharged through the one-way valve at the upper end of the air bag 11, making the interior vacuum. At this time, the air bag 11 is released to auxiliary-suction the tissue fluid and other debris in the catheter 5 into the covering cover 1, and the cause of the blockage can be quickly observed.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
