Abstract
Description
Technical Field
[0001] The invention belongs to the field of medical negative pressure drainage, in particular to a drainage device for tumor internal medicine. Background Art
[0002] Patients with malignant tumors often have refractory pleural or peritoneal effusions. The drainage fluid is highly viscous and easily coagulated. After surgery, patients need to drain the fluid through a drainage tube and live with the tube for a certain period of time. One end of the drainage tube is inserted into the patient's body, and the other end is connected to the drainage bottle. In the patient's daily normal life, as the body position changes, other parts of the body are squeezed, and the part of the drainage tube in contact with the body is repeatedly bent. After bending, the drainage tube is easily squeezed at that part, which in turn affects the normal flow rate of the drainage tube. Severe cases may also cause the drainage tube to be unable to drain normally, causing extravasation of accumulated fluid or the inability of the accumulated fluid to flow out normally, affecting the normal drainage work in the body and endangering health. Moreover, if the highly viscous and easily coagulated accumulated fluid is accumulated in the drainage tube for a long time and cannot be cleared normally, it will cause blockage of the drainage tube. The bending of the drainage tube is usually an unconscious behavior of the patient and is not easy to be discovered, further increasing the risk of blockage.

[0020] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0021] like Figures 1-9 As shown, the present invention provides an oncology internal medicine drainage device, including a negative pressure drainage bottle 1 and a drainage tube 3. A sealing plug 10 is provided at the bottle mouth of the negative pressure drainage bottle 1. A suction joint and a suction pipe are installed on the sealing plug 10. The suction joint is connected to one end of the drainage tube 3. A positioning ring seat 7 is provided at the end of the drainage tube 3 away from the negative pressure drainage bottle 1. A drainage tube hole is opened in the middle of the positioning ring seat 7. One end of the drainage tube 3 passes through the drainage tube hole. There is no less than one locking pipe member 8 in the middle of the positioning ring seat 7. A locking cover 4 is provided on the surface of the positioning ring seat 7, a tape ring is installed at the bottom of the positioning ring seat 7, and a medical elastic tape 2 is pasted on the surface of the tape ring. A through hole is provided in the middle of the locking cover 4, and a top ring 9 is installed in the middle of the locking cover 4. One side of the top ring 9 is in contact with the lock tube member 8. A threaded groove is provided on the inner wall of the locking cover 4, and a matching threaded groove is provided on the outer wall of the positioning ring seat 7. The locking cover 4 and the positioning ring seat 7 are connected by threads, and a movable clamp is provided on the surface of the bottle mouth of the negative pressure drainage bottle 1.
[0022] As an embodiment of the present invention, an opening is provided in the middle of the medical elastic tape 2, the middle opening of the medical elastic tape 2 passes through the positioning ring seat 7, and fits with the surface of the tape ring, and at least one drainage tube buckle 6 is fixedly connected to the surface of the medical elastic tape 2. The drainage tube buckle 6 is a "C"-shaped structure, and a bevel block is installed on the inner wall of one end of the drainage tube buckle 6 near the opening.
[0023] Among them, the base fabric of the medical elastic tape 2 is a non-woven polyester fiber material, and hot melt adhesive is evenly coated on one surface. Part of the adhesive surface contacts the tape ring and is sealed and bonded. The drainage tube buckle 6 is installed on the side of the medical elastic tape 2 that does not contain adhesive. The drainage tube buckle 6 locks part of the exposed end of the drainage tube 3, changes the traction direction of the drainage tube 3, and also limits the position of the drainage tube 3. In addition to the locking tube 8, a fixing method for the drainage tube 3 is added from the outside, such as Figure 1-Figure 2On the one hand, the direction of the drainage tube 3 is changed to prevent the drainage tube from bending, and on the other hand, the drainage tube 3 is fixed to prevent it from being separated from the patient's body.
[0024] As an embodiment of the present invention, the tape ring is arranged along the outer wall of the positioning ring seat 7, and a side of the tape ring away from the positioning ring seat 7 is connected to a silicone sealing strip.
[0025] like Figure 4 The silicone sealing strip is arranged along the bottom shape of the tape ring. The setting of the silicone sealing strip is to better contact with the surface of the skin. The tape ring and the skin are seamlessly contacted by the silicone sealing strip. The sealing strip with the silicone structure can better adhere to the skin surface, so that the positioning ring seat 7 can be limited to the surface of the drainage port of the patient's body, preventing the positioning ring seat 7 from being moved during the movement of the patient, thereby increasing the friction between the positioning ring seat 7 and the patient's skin surface.
[0026] As an embodiment of the present invention, a plurality of locking grooves are provided in the positioning ring seat 7, and the locking tubes 8 are arranged in one-to-one correspondence with the locking grooves. The locking grooves pass through the middle of the positioning ring seat 7 and are connected to the drainage pipe holes. The drainage pipe holes of the locking grooves are arranged in a circular array.
[0027] As an embodiment of the present invention, the locking tube member 8 includes an arc-shaped base block 801, the arc surface of the arc-shaped base block 801 matches the curvature of the inner wall of the drainage tube hole, the convex end of the arc-shaped base block 801 is installed with a slope block 802, the slope block 802 is movably contacted with the top ring 9, the slope block 802 is arranged above the positioning ring seat 7, and an insert block 803 is installed on one side of the arc-shaped base block 801, one end of the insert block 803 is movably inserted into the locking member groove, and the concave end of the arc-shaped base block 801 is arranged close to the drainage tube 3.
[0028] Among them, such as Figure 5-Figure 6 The arc-shaped base block 801 is inserted into the locking groove through the insert block 803, and the inclined surface block 802 is above the positioning ring seat 7. When the top ring 9 moves downward, the inclined surface block 802 is squeezed along the inclined surface structure of the inclined surface block 802, so that the arc-shaped base block 801 is gathered and clamped on the surface of the drainage tube 3, locking the position of the drainage tube 3.
[0029] As an embodiment of the present invention, the concave end of the arc-shaped base block 801 is fitted with a silicone anti-slip sheet 804 , and the silicone anti-slip sheet 804 is in contact with the drainage tube 3 .
[0030] like Figure 6The silicone anti-slip sheet 804 is in contact with the drainage tube 3 to increase the friction between the drainage tube 3 and the locking tube member 8, preventing the drainage tube 3 from sliding during daily use. The setting of the silicone anti-slip sheet 804 can also play a buffering role when the locking tube member 8 clamps the drainage tube 3, preventing hard direct clamping and excessive clamping, which will cause the drainage tube 3 to be squeezed and deformed, affecting the normal drainage function of the drainage tube 3.
[0031] As an embodiment of the present invention, the inner ring surface of the top ring 9 is a bevel, and matches the bevel of the bevel block 802 .
[0032] The inclined surface of the top ring 9 squeezes the inclined surface block 802, and when the positioning ring seat 7 drives the top ring 9 to move downward, the top ring 9 squeezes the locking tube 8 along the inclined surface, which plays the role of clamping the drainage tube 3. It is no longer necessary to fix the drainage tube 3 to the patient's skin surface by sutures, thereby alleviating the patient's pain.
[0033] As an embodiment of the present invention, a transparent cover 5 is provided on the surface of the locking cover 4, and the transparent cover 5 includes an adhesive seat and a pipe cover. The adhesive seat is matched with the surface of the locking cover 4, and the pipe cover is installed in the middle of the adhesive seat and has a hollow structure with an open structure at the bottom.
[0034] As shown in Figure 7, the bottom of the transparent cover 5 is coated with hot-melt adhesive and adhered to the surface of the locking cover 4. The drainage tube 3 is exposed at one end of the skin and bent at 90 degrees, and then fixed by the drainage tube buckle 6. The pipe cover covers the surface of the arc-shaped bend of the drainage tube 3 to prevent the formation of creases at the bend of the drainage tube 3, squeezing the drainage tube 3 and preventing it from draining normally.
[0035] As an embodiment of the present invention, the movable clamp includes a hook clamp block 11 and a hook clamp block 2 15. The hook clamp block 11 and the hook clamp block 2 15 are semicircular structures and are connected end to end. The two ends of the hook clamp block 11 are respectively fixedly connected with a dovetail block 18, and the two ends of the hook clamp block 2 15 are respectively provided with a dovetail groove 16. The dovetail block 18 is movably inserted into the dovetail groove 16 from top to bottom. The middle part of the hook clamp block 2 15 is fixedly connected with a hook 13, and a restraining belt hole 14 is provided on the end of the hook 13 away from the hook clamp block 2 15, and a restraining belt 12 is provided through the restraining belt hole 14.
[0036] like Figure 8-Figure 9The hook block 11 is inserted into the hook block 2 15 and surrounds the surface of the bottle mouth. The dovetail groove 16 does not penetrate the hook block 2 15. The hook block 11 is plugged vertically from top to bottom. When hanging, the hook 13 is hooked, and the hook 13 exerts an upward force, driving the hook block 2 15 to exert an upward force, so that the hook block 11 is squeezed on the surface of the bottle mouth, preventing the hook block 11 from detaching from the hook block 2 15. When the patient moves, the restraint belt 12 can be used to limit the patient's waist or other parts of the body, so that the patient can move normally.
[0037] As an embodiment of the present invention, a limit block 17 is installed at the bottle mouth of the negative pressure drainage bottle 1. The limit block 17 is arranged above the movable clamp and has a semicircular arc structure.
[0038] Among them, the radius of the limit block 17 is larger than the radius of the hook block 11 and the hook block 2 15, and is blocked on the surface of the movable clamp. During installation, the negative pressure drainage bottle 1 is rotated, and the hook block 2 15 is aligned with the limit block 17 and is below the limit block 17. At this time, there is no limit block 17 blocking the top of the hook block 11, and the two ends of the hook block 2 15 can be inserted from top to bottom, and wrapped in a ring shape with the hook block 2 15 on the surface of the bottle mouth. Then the negative pressure drainage bottle 1 is rotated, and the limit block 17 is aligned with the top of the hook block 11 to limit the upward movement direction of the hook block 11. Since the limit block 17 is a semicircular structure, even when the negative pressure drainage bottle 1 moves, the negative pressure drainage bottle 1 rotates in the movable clamp, the limit block 17 can always partially position the hook block 11. When performing drainage on an oncology patient, the drainage tube 3 passes through the middle of the positioning ring seat 7 and the locking cover 4. After the drainage tube 3 is inserted into the patient, the positioning ring seat 7 is moved to the patient's skin surface. The drainage tube buckle 6 is directed toward the patient's feet in the direction of the human body. The positioning ring seat 7 covers the surface of the patient's puncture site, and the medical elastic tape 2 is adhered to the patient's skin surface. When fixing the drainage tube 3, the locking cover 4 is rotated and approaches the positioning ring seat 7, and the inclined block 802 is squeezed through the top ring 9, and then the silicone anti-slip sheet 804 is clamped on the surface of the drainage tube 3 to prevent the drainage tube 3 from being pulled out of the patient's body; While ensuring that the drainage tube 3 is not bent or compressed, the direction of the drainage tube 3 is changed and bent at 90 degrees so that it cannot squeeze the drainage tube 3 and affect the normal drainage function of the drainage tube 3. The transparent cover 5 covers the surface of the bend and the drainage tube 3 is clamped by the drainage tube buckle 6.
