Description

Technical Field

[0001] This invention relates to the technical field of fluid drainage devices for tumor care, specifically to a fluid drainage device for tumor care. Background Technology

[0002] The Department of Oncology primarily treats various benign and malignant tumors. In the later stages of cancer treatment, patients are prone to pleural effusions, which, if not treated promptly, can hinder cancer treatment. Therefore, during treatment, medical staff often use drainage devices to drain the pleural effusion. During drainage procedures, to improve drainage or comfort, it is often necessary to change the position of the drainage bottle and tube, or temporarily separate the drainage tube and bottle due to blockages or other issues.

[0003] Currently, most drainage devices use threaded connections to fix the drainage tube and drainage bottle. When the drainage bottle and drainage tube are moved together after fixing, the drainage tube is prone to twisting. If the threaded connection is rotated to release the twist, the connection will loosen, affecting the negative pressure drainage effect. If the drainage end is moved to release the twist, it can easily cause pain to the patient. When it is necessary to separate the drainage tube and drainage bottle, both need to be rotated significantly to disengage from the threaded connection, causing the drainage tube to twist significantly, which can easily cause secondary injury to the patient. Summary of the Invention

[0004] The purpose of this invention is to provide a fluid drainage device for tumor care, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solutions:

[0006] This invention discloses a drainage device for tumor care, comprising a drainage bottle, a miniature negative pressure pump and an inlet pipe at the top of the drainage bottle, the inlet pipe being able to connect with the drainage pipe, the inner wall of the inlet pipe having a spherical annular groove, the drainage pipe having a connector pipe, the connector pipe including an inner tube and a sleeve, the drainage pipe being fixedly connected to the top end of the inner tube, the sleeve being fitted over the outer side of the inner tube and being slidable, the sleeve and the upper part of the inner tube forming a tubular cavity, the tubular cavity being provided with a plurality of springs, the lower end of the springs being fixedly connected to the inner tube, and the upper end being covered by the sleeve;

[0007] The lower part of the inner tube is inverted conical, and the lower part of the sleeve is provided with several downward-sloping sliding holes. A sliding locking head is provided in the downward-sloping sliding hole. The outer surface of the locking head is spherical and can be nested with the spherical annular groove. The inner end of the locking head slides with the inverted conical surface of the lower part of the inner tube.

[0008] As an improvement, a protruding ring is provided at the bottom end of the inverted conical surface, and the protruding ring limits the locking head.

[0009] As an improvement, the inner end of the latch head is provided with a slot, and the inverted conical surface is provided with several guide strips, and the slot engages with the guide strips in a sliding fit.

[0010] As an improvement, four downward-sloping sliding holes and four locking heads are provided.

[0011] As an improvement, the bottom end of the sleeve is provided with a fixed support plate, which supports and limits the convex ring. The bottom of the convex ring of the inner tube is provided with a fixed extension tube, the bottom of which passes through the support plate and slides with the support plate.

[0012] As an improvement, the top of the inner tube is provided with a fixed cover plate, which covers the top of the sleeve.

[0013] As an improvement, the diameter of the cover plate is larger than that of the sleeve, and the area around the cover plate is anti-slip.

[0014] As an improvement, the spring has eight springs.

[0015] As an improvement, a drainage ball is provided at the front end of the drainage tube.

[0016] The advantages of this invention compared with the prior art are as follows: the drainage tube is equipped with a connector tube, and the connection with the drainage bottle is achieved by directly inserting the connector tube into the inlet tube. After the locking head and the spherical annular groove are properly engaged, the drainage tube and the drainage bottle can still rotate relative to each other without causing the connection to loosen. When the drainage tube and the drainage bottle are moved together to change positions, the twisting of the drainage tube can be released by rotating the connector tube without causing the connection to loosen, and the negative pressure drainage effect is not affected.

[0017] The connector tube can be pulled out by squeezing the cover plate and pulling it upwards, thus releasing the locking head and the spherical annular groove, and separating the drainage tube from the drainage bottle. There is no need to rotate the drainage tube, avoiding secondary damage to the patient caused by twisting the drainage tube. Attached Figure Description

[0034] This embodiment is combined with the appendix Figures 1 to 8 This paper provides a detailed description of a fluid drainage device for tumor care.

[0035] This embodiment discloses a drainage device for tumor care, comprising a drainage bottle 1. The top of the drainage bottle 1 is equipped with a miniature negative pressure pump 2 and an inlet pipe 3. The drainage bottle 1, miniature negative pressure pump 2, and inlet pipe 3 adopt existing designs. The inlet pipe 3 can be connected to a drainage pipe 4. The inner wall of the inlet pipe 3 has a spherical annular groove 31 for snap-fitting. The drainage pipe 4 is equipped with a connector pipe 5, which includes an inner tube 51 and a sleeve 52. The drainage pipe 4 is fixedly connected to the top of the inner tube 51. Drainage fluid enters the inner tube 51 through the drainage pipe 4. The sleeve 52 is fitted over the inner tube 51 and is slidable. The sleeve 52 and the upper part of the inner tube 51 form a tubular cavity 6. Several springs 7 are provided inside the tubular cavity 6. Natural or slight compression pushes the inner tube 51 downwards. The lower end of each spring 7 is fixedly connected to the inner tube 51, and the upper end of each spring 7 is a movable end covered by the sleeve 52. The sleeve 52 can slide relative to the springs 7 on a horizontal plane.

[0036] The lower part of the inner tube 51 is inverted conical, which facilitates the pushing of the locking head 9. The lower part of the sleeve 52 is surrounded by several downward-sloping sliding holes 8. A slidable locking head 9 is located within each downward-sloping sliding hole 8. The outer surface of the locking head 9 is spherical, with 1 / 4 to 1 / 3 of the spherical surface nesting with the spherical annular groove 31. The inner end of the locking head 9 (the end facing the inner tube 51) slides with the inverted conical surface 10 at the lower part of the inner tube 51. The inverted conical surface 10 slides and pushes the locking head 9, allowing the spherical end of the locking head 9 to protrude from the downward-sloping sliding hole 8, and then nest and lock with the spherical annular groove 31.

[0037] The bottom end of the inverted conical surface 10 is provided with a protruding ring 11, which limits the locking head 9 and prevents the locking head 9 from slipping off the inverted conical surface 10.

[0038] The inner end of the latch head 9 is provided with a slot 91, and the inverted conical surface 10 is provided with a plurality of guide strips 101. The slot 91 engages with the guide strips 101 in a sliding fit, and the guide strips 101 guide the latch head 9 to slide in a straight line.

[0039] The downward-sloping sliding hole 8 and the locking head 9 are each provided in four parts.

[0040] The bottom end of the sleeve 52 is provided with a fixed support plate 12, which is integrally connected. The support plate 12 is shaped like a ring plate facing inwards from the sleeve 52. Figure 2 The support plate 12 supports and limits the convex ring 11. The bottom of the convex ring 11 of the inner tube 51 is provided with a fixed extension tube 13. The bottom of the extension tube 13 passes through the support plate 12 and slides with the support plate 12. The extension tube 13 better guides the inner tube 51 to slide vertically and can also play a sealing role to prevent the drainage fluid from seeping into the gap between the inner tube 51 and the sleeve 52.

[0041] The inner tube 51 is provided with a fixed cover plate 14 at the top end, which is fixedly connected to the inner tube 51 in an integral manner, and is shaped like a ring plate. The cover plate 14 covers the top of the sleeve 52 and limits the position of the sleeve 52.

[0042] The diameter of the cover plate 14 is larger than that of the sleeve 52. The cover plate 14 is non-slip around its perimeter, making it easy to turn the inner tube 51 by hand.

[0043] There are eight springs 7. They are evenly distributed circumferentially to ensure that the inner tube 51 and the supporting sleeve 52 are subjected to balanced forces when they slide relative to each other.

[0044] The front end of the drainage tube 4 is provided with a drainage ball 41, which can absorb liquid in multiple holes and directions.

[0045] In practice, the drainage bulb 41 of the drainage tube 4 is inserted into the patient's pleural effusion site. Holding the connector tube 5, the inner tube 51 and the cannula 52 are pulled apart slightly. Figure 3The locking head 9 retracts into the downward-sloping sliding hole 8, and then the sleeve 52 is inserted into the liquid inlet pipe 3. At this time, the spring 7 is in a compressed state until the locking head 9 is engaged with the spherical annular groove 31. Under the action of the spring 7, the inverted conical surface 10 pushes the locking head 9 outward to engage with the spherical annular groove 31, and at the same time, the inner tube 51 automatically retracts. Figure 1 Complete the connection between the drainage tube 4 and the inlet tube 3. After connection, start the miniature negative pressure pump 2 to perform drainage. The miniature negative pressure pump 2 extracts the air from the inside of the drainage bottle 1 to create a negative pressure space, thereby allowing the effusion in the patient's chest to flow into the inside of the drainage bottle 1 through the drainage tube 4, thus achieving drainage treatment.

[0046] If it is necessary to move the drainage tube 4 and drainage bottle 2 to different positions, first hold the drainage tube 4 near the drainage end with one hand to prevent the drainage end from moving around and causing pain to the patient. Then, use the other hand to take the drainage bottle 2 to the required position (changing the position may cause some twisting to the drainage tube 4). Then, slightly rotate the cover plate 14, and the connector tube 5 will rotate as a whole to release the twisting of the drainage tube 4. Finally, release your hands.

[0047] When the drainage tube 4 is separated from the drainage bottle 2, grasp the cover plate 14 and pull the inner tube 51 upwards. The inverted conical surface 10 and the guide strip 101 move upwards, causing the locking head 9 to slide down relative to the guide strip 101 and simultaneously retract into the downward-sloping sliding hole 8, disengaging from the spherical annular groove 31. Figure 3 At this point, the sleeve 52 disengages from the inlet pipe 3 and is pulled out of the inlet pipe 3, completing the separation of the drainage pipe 4 from the drainage bottle 2.

[0048] The present invention and its embodiments have been described above. This description is not restrictive, and the actual scope of protection is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this invention should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope of the claims.
