Description

Technical Field

[0001] The present invention relates to the technical field of effusion discharge devices for tumor care, and in particular to an effusion discharge device for tumor care. Background Art

[0002] The Department of Oncology is mainly engaged in the medical treatment of various benign and malignant tumors. Tumor patients are prone to effusion in the chest and other parts in the later stage. If not treated in time, it will affect the treatment of the tumor. Therefore, during the treatment process, medical staff often use drainage devices to drain the patient's pleural effusion. During the drainage operation, in order to better drain or improve comfort, it is often necessary to change the position of the drainage bottle and drainage tube, or temporarily separate the drainage tube and drainage bottle due to blockage and other problems.

[0003] At present, the drainage tube and drainage bottle of most drainage devices are fixed by threaded connection. After fixation, when the drainage bottle and the drainage tube are replaced together, the drainage tube is easily twisted. If the threaded connection end is rotated to release the twisting, the connection will become loose, affecting the negative pressure drainage effect. If the movable drainage end is released to twist, it will easily cause pain to the patient. When the drainage tube and the drainage bottle need to be separated, the two need to be rotated significantly to disengage the threaded connection, causing the drainage tube to twist significantly, which can easily cause secondary injury to the patient.

[0034] This embodiment combines the attached Figures 1 to 8 , a fluid discharge device for tumor care is described in detail.

[0035] The present embodiment is a fluid discharge device for tumor nursing, comprising a drainage bottle 1, wherein a micro negative pressure pump 2 and a liquid inlet pipe 3 are arranged on the top of the drainage bottle 1, the drainage bottle 1, the micro negative pressure pump 2 and the liquid inlet pipe 3 adopt the existing design, the liquid inlet pipe 3 can be docked with the drainage tube 4, the inner wall of the liquid inlet pipe 3 is provided with a spherical annular groove 31 for clamping, the drainage tube 4 is provided with a joint pipe 5, the joint pipe 5 includes an inner tube 51 and a sleeve 52, the drainage tube 4 is fixedly connected with the top of the inner tube 51, the drainage fluid enters the inner tube 51 through the drainage tube 4, the sleeve 52 is sleeved on the outside of the inner tube 51 and can slide, the sleeve 52 and the upper part of the inner tube 51 form a tubular cavity 6, a plurality of springs 7 are arranged in the tubular cavity 6, which push the inner tube 51 downward naturally or with slight compression, the lower end of the spring 7 is fixedly connected with the inner tube 51, the upper end of the spring 7 is a movable end covered by the sleeve 52; the sleeve 52 can slide relative to the spring 7 in a horizontal plane;

[0036] The lower part of the inner tube 51 is inverted cone, which is conducive to pushing the lock head 9. A plurality of downward sliding holes 8 are arranged around the lower part of the sleeve 52. The downward sliding holes 8 are provided with a slidable lock head 9. The outer surface of the lock head 9 is spherical, and 1 / 4-1 / 3 of the spherical surface is nested with the spherical annular groove 31. The inner end of the lock head 9 (the end facing the inner tube 51) is slidably matched with the inverted cone surface 10 at the lower part of the inner tube 51. The inverted cone surface 10 slides and pushes the lock head 9, so that the spherical end of the lock head 9 can be exposed from the downward sliding hole 8, and then nested with the spherical annular groove 31.

[0037] A convex ring 11 is provided at the bottom end of the inverted conical surface 10 , and the convex ring 11 limits the locking head 9 to prevent the locking head 9 from slipping off the inverted conical surface 10 .

[0038] The inner end of the lock 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 clamps the guide strips 101 for sliding fit, and the guide strips 101 guide the lock head 9 to slide linearly.

[0039] The downward sliding holes 8 and the locking heads 9 are each provided with four.

[0040] The bottom end of the sleeve 52 is provided with a fixed support plate 12, which is fixedly connected as a whole. The support plate 12 is shaped like a ring plate facing the inside of the sleeve 52. Figure 2 The support plate 12 supports and limits the convex ring 11. A fixed extension tube 13 is provided at the bottom of the convex ring 11 of the inner tube 51. 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 vertical sliding of the inner tube 51 and also plays a sealing role to prevent the drainage fluid from seeping into the gap between the inner tube 51 and the sleeve 52.

[0041] A fixed cover plate 14 is provided at the top of the inner tube 51 , which is fixedly connected to the inner tube 51 and is shaped like a ring plate. The cover plate 14 covers the top of the sleeve 52 to limit the position of the sleeve 52 .

[0042] The diameter of the cover plate 14 is larger than that of the sleeve 52 , and the periphery of the cover plate 14 is non-slip, so that the inner tube 51 can be easily twisted by hand.

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

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

[0045] In the specific implementation, the drainage ball 41 of the drainage tube 4 is inserted into the pleural effusion of the patient, the joint tube 5 is held by hand, and the inner tube 51 and the sleeve 52 are slightly pulled apart. Figure 3, the lock head 9 is retracted into the downward sliding hole 8, and then the sleeve 52 is inserted into the liquid inlet pipe 3. The spring 7 is in a compressed state at this time, until the lock head 9 is stuck on the spherical annular groove 31. Under the action of the spring 7, the inverted conical surface 10 squeezes the lock head 9 outward and sticks on the spherical annular groove 31, and the inner tube 51 automatically retracts. Figure 1 , the drainage tube 4 is connected to the liquid inlet tube 3. After the connection is completed, the micro negative pressure pump 2 is started to perform drainage work, and the micro negative pressure pump 2 extracts the air inside the drainage bottle 1 to create a negative pressure space, so that the effusion in the patient's chest flows into the drainage bottle 1 through the drainage tube 4, and the drainage treatment is achieved.

[0046] If it is necessary to move the drainage tube 4 and the drainage bottle 2 to change their 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 is likely to cause a certain degree of twisting of the drainage tube 4), then slightly rotate the cover plate 14, the joint tube 5 rotates as a whole, releases the twisting of the drainage tube 4, and finally lets go.

[0047] When the drainage tube 4 is separated from the drainage bottle 2, the cover plate 14 is grasped and the inner tube 51 is pulled upward, the inverted conical surface 10 and the guide strip 101 move upward, driving the lock head 9 to slide downward relative to the guide strip 101 and retreat into the downward sliding hole 8, and disengage from the spherical annular groove 31. Figure 3 At this time, the sleeve 52 is separated from the clamping connection with the liquid inlet tube 3 and is pulled out of the liquid inlet tube 3, completing the separation of the drainage tube 4 and the drainage bottle 2.

[0048] The present invention and its embodiments are described above, and such description is not restrictive, and the actual protection scope is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
