[0002] A drainage bottle is a medical device used in drainage procedures such as chest drainage or abdominal drainage. Medical staff use drainage tubes and negative pressure equipment to drain the accumulated fluid or gas in the chest or abdominal cavity into the drainage bottle to relieve the squeezing and impact of the accumulated fluid or gas on the patient's organs, thereby avoiding complications such as difficulty breathing.

[0003] Drainage in the prior art is to connect a drainage bottle and a drainage tube, and the other end of the drainage tube is connected to the patient's body to drain the concentrated water or blood accumulated in the patient's body through the negative pressure inside the drainage bottle. However, in the prior art, after the drainage device is connected to the patient, the drainage bottle is usually just placed on the ground. However, hospitals are crowded with people, and placing the drainage bottle directly on the ground may be accidentally touched by humans, causing the drainage bottle to fall over, thereby interrupting or affecting the drainage. A fixable drainage bottle is needed. For this purpose, the present invention provides a micro negative pressure chest drainage bottle and a micro negative pressure chest drainage device.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention. Example

[0021] See also Figures 1-5 The present invention provides the following technical solutions: a micro-negative pressure chest drainage bottle and a micro-negative pressure chest drainage device, comprising a drainage tube body 1, a breathable valve 2 and a drainage bottle body 3, the drainage tube body 1 and the breathable valve 2 are fixedly mounted on one side of the top of the drainage bottle body 3, characterized in that: a base 6 is fixed to the bottom of the drainage bottle body 3, and supporting feet 5 for auxiliary support of the drainage bottle body 3 are symmetrically arranged at the bottom of the base 6, a fixing block 10 is fixed to one side of the drainage bottle body 3, a fixing pin 12 is passed through the fixing block 10, a fixing pin 12 is connected to a fixing plate 4 on the side away from the fixing block 10, a clamping piece 9 is fixed to the side of the fixing plate 4 away from the fixing pin 12, a threaded rod 8 for fixing the clamping piece 9 is screwed on the clamping piece 9, and the drainage bottle body 3 can be fixed by the fixing block 10 and the fixing pin 12; when in use, the fixing block 10 on the drainage bottle body 3 is aligned and inserted into the sleeve ring 11 In the embodiment, because the head end of the fixing pin 12 is designed with an inclined surface, when the fixing block 10 touches the fixing pin 12, it will have a pressing effect on it and cause the fixing pin 12 to move toward the tail end. When the fixing block 10 is inserted into the sleeve ring 11, the fixing pin 12 will be pushed into the waist-shaped hole on the fixing block 10 due to the tension of the spring 14, and the installation of the fixing assembly can be completed. Then the clamping piece 9 is clamped in a fixed position on the patient's bed, and the knob 7 is rotated clockwise to squeeze the threaded rod 8 onto the bed and play a fixing role. At this time, the fixing work of the drainage bottle body 3 can be completed; after the drainage tube body 1 is connected to the patient's body, drainage work can be carried out; if the drainage bottle body 3 needs to be disassembled, just pull the pull ring 16 to pull the fixing pin 12 out of the fixing block 10, and the drainage bottle body 3 can be removed therefrom, or rotate the knob 7 counterclockwise to disengage the threaded rod 8 from its fixed position.

[0022] Specifically, a waist-shaped hole is provided on the fixing block 10, and the fixing block 10 can be fixed by inserting a fixing pin 12 into the waist-shaped hole on the fixing block 10. The waist-shaped hole is slightly larger than the fixing pin 12. When the fixing block 10 is inserted and fixed, the fixing pin 12 can be inserted into the waist-shaped hole more smoothly.

[0023] Specifically, the head end of the fixing pin 12 has a bevel, a fixing plate 13 is fixed in the middle of the fixing pin 12, and a mounting plate 15 is slidably penetrated near the tail end of the fixing pin 12. The fixing pin 12 can slide on the mounting plate 15. The mounting plate 15 can support the fixing pin 12 and enable the fixing pin 12 to have a certain moving route and a certain limiting effect. The spring 14 is located between the mounting plate 15 and the fixing plate 13. The mounting plate 15 can provide the spring 14 with a support point and can effectively push the fixing pin 12 to move through the fixing plate 13.

[0024] Specifically, a pull ring 16 is fixed at the tail end of the fixing pin 12 to assist in pulling the fixing pin 12 . The pull ring 16 can assist in pulling the fixing pin 12 , making it more convenient to operate the fixing pin 12 .

[0025] Specifically, a sleeve ring 11 is fixed to the side of the fixing plate 4 close to the drainage bottle body 3, and a fixing pin 12 passes through the sleeve ring 11. The fixing block 10 can be moved into the sleeve ring 11 through the drainage bottle body 3 and fixed by the fixing pin 12. The diameter of the sleeve ring 11 is slightly larger than the fixing block 10. The setting of the sleeve ring 11 can enable the fixing block 10 to be quickly fixed.

[0026] Specifically, a spring 14 is provided on the fixing pin 12 to enable the fixing pin 12 to move. The spring 14 is provided between the mounting plate 15 and the fixing plate 13. The spring 14 has a certain tension and is provided between the mounting plate 15 and the fixing plate 13. Since the mounting plate 15 cannot move, the spring 14 can only push the fixing plate 13 to move, thereby enabling the fixing pin 12 to move and giving the fixing pin 12 a certain force when inserted and fixed, thereby preventing it from falling off.

[0027] Specifically, a fixing column 17 is fixed on one side of the clamping piece 9 close to the fixing plate 4, and the other side of the fixing column 17 is fixed on the fixing plate 4. The clamping piece 9 is fixed to the fixing plate 4 through the fixing column 17, and a knob 7 for assisting in rotating the threaded rod 8 is fixed on the end of the threaded rod 8 away from the clamping piece 9. The knob 7 can assist in rotating the threaded rod 8, making the operation of the threaded rod 8 more convenient.

[0028] The working principle and use process of the present invention are as follows: when in use, align the fixing block 10 on the drainage bottle body 3 and insert it into the sleeve ring 11. Because the head end of the fixing pin 12 is designed with a bevel, when the fixing block 10 touches the fixing pin 12, it will have a pressing effect on it and move the fixing pin 12 toward the tail end. When the fixing block 10 is inserted into the sleeve ring 11, the fixing pin 12 will be pushed into the waist-shaped hole on the fixing block 10 due to the tension of the spring 14, and the installation of the fixing assembly can be completed. Then, the clamping piece 9 is clamped. It is set at a fixed position on the patient's bed, and then the knob 7 is rotated clockwise to squeeze the threaded rod 8 onto the bed and fix it. At this time, the fixation of the drainage bottle body 3 can be completed; after the drainage tube body 1 is connected to the patient's body, drainage can be carried out; if the drainage bottle body 3 needs to be disassembled, it is only necessary to pull the pull ring 16 to pull the fixing pin 12 out of the fixing block 10 to remove the drainage bottle body 3 therefrom, or rotate the knob 7 counterclockwise to disengage the threaded rod 8 from its fixed position.
