[0002] Neurosurgical patients in critical condition often require suctioning, a crucial medical procedure that effectively clears respiratory secretions, maintains airway patency, and prevents complications such as aspiration pneumonia and suffocation. Currently, after suctioning, the collection container needs to be quickly sealed to prevent spillage and leakage. However, existing sputum collectors lack a rapid sealing mechanism; the tubing connection is typically sealed only after extubation, resulting in low overall efficiency.
[0003] Therefore, we propose a sputum collector and a sputum suction device to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0027] Reference Figure 1-7 A sputum collector includes a collection bottle body 1. The collection bottle body 1 has a bottle opening at the top and a cap 2 connected to it. The cap 2 has a first interface 3 and a second interface 4 at the top. The first interface 3 and the second interface 4 are respectively connected to a first rubber tube 5 and a second rubber tube 6, and the first rubber tube 5 and the second rubber tube 6 extend to the bottom of the cap 2. The first interface 3 is connected to an existing suction catheter, which is usually a tube made of soft plastic and is used to insert into the patient's airway to suction and clear secretions such as sputum and saliva from the airway, preventing the patient from experiencing symptoms such as difficulty breathing, suffocation, and respiratory failure due to sputum blockage.
[0028] A horizontal insert plate 7 is provided on the side of the cover 2. The cover 2 has an insertion hole that matches the insert plate 7. The bottom of the cover 2 has a waist-shaped slot 8 corresponding to the first rubber tube 5 and the second rubber tube 6. The waist-shaped slot 8 ensures that the first rubber tube 5 and the second rubber tube 6 extend into the bottom of the cover 2. The insert plate 7 can push the first rubber tube 5 and the second rubber tube 6. By pushing the insert plate 7, it can be inserted into the insertion hole of the cover 2. After the insert plate 7 is fully inserted into the insertion hole, it can push the first rubber tube 5 and the second rubber tube 6, and squeeze and bend the first rubber tube 5 and the second rubber tube 6 and retract them into the waist-shaped slot 8. At this time, the insert plate 7 effectively squeezes and seals the first rubber tube 5 and the second rubber tube 6 as well as the waist-shaped slot 8, thus achieving the effect of sealing the first interface 3 and the second interface 4.
[0029] As a technical optimization of this utility model, the edges of the first interface 3 and the second interface 4 are both sealed to the cover 2, and the length of the first rubber tube 5 is longer than the length of the second rubber tube 6.
[0030] As a technical optimization of this utility model, the inner wall of the insertion hole of the cover 2 is provided with a rubber layer 9, which wraps and fits the outer side of the insertion plate 7. The rubber layer 9 can effectively ensure the sealing of the gap on the outer side of the insertion plate 7.
[0031] As a technical optimization of this utility model, two optical rods 10 are fixed on both sides of one end of the insert plate 7, and the cover 2 is provided with slots that match the two optical rods 10. The optical rods 10 are slidably inserted into the cover 2. The two optical rods 10 serve to stabilize the insert plate 7.
[0032] As a technical optimization of this utility model, both ends of the two smooth rods 10, one near the cover 2 and the other away from the cover 2, are provided with notches 11. A bracket 12 is rotatably mounted on the upper side of the cover 2, and two bent rods 13 are symmetrically mounted on the bracket 12. The two bent rods 13 can respectively engage with the two notches 11. That is, the two bent rods 13 can be inserted and engaged with the two notches 11 respectively. After the two bent rods 13 engage with the two notches 11, the sliding of the two smooth rods 10 can be restricted, that is, the sliding of the insert plate 7 can be restricted.
[0033] As a technical optimization of this utility model, two side blocks 14 are fixed to the top of the cover 2, and the bracket 12 is rotatably disposed between the two side blocks 14. Each of the two bent rods 13 has a locking block 15 fixed to its side, and the two side blocks 14 have locking grooves that engage with the two locking blocks 15. When the two bent rods 13 are inserted into and engaged with the two notches 11, the two side blocks 14 engage with the two locking blocks 15, meaning the bracket 12 is locked and fixed to the cover 2, effectively ensuring the stability of the two bent rods 13.
[0034] A sputum suction device includes a suction device body 16, a collection bottle body 1 mounted on the suction device body 16, and a negative pressure endotracheal tube 17 connected between a second interface 4 and the suction device body 16. When the suction device body 16 is activated, the negative pressure endotracheal tube 17 generates negative pressure, which reduces the air pressure inside the collection bottle body 1, thereby enabling suctioning through the first interface 3. The specific suctioning operation is not described in detail.
[0035] For the above example, those skilled in the art should know that when implementing the above technical solution, the suction device body 16 is a common handheld suction device, such as the existing SMAF low negative pressure electric suction device, which can be used by connecting to electricity. The suction device body 16 is equipped with an air pump, which is a negative pressure terminal connected to a filter cartridge. The filter cartridge is connected to the negative pressure air tube 17, which can generate negative pressure airflow in the negative pressure air tube 17.
[0036] In this invention, the working principle of the device is as follows:
[0037] During sputum collection, the first interface 3 connects to the existing suction tube, and the second interface 4 connects to the suction device body 16 via a negative pressure duct 17. After the suction device body 16 is activated, the negative pressure duct 17 generates negative pressure, reducing the air pressure inside the collection bottle body 1. This allows the suction tube connected to the first interface 3 to perform suction, thus achieving sputum collection from the collection bottle body 1. After sputum collection is complete, the insert plate 7 can be pushed into the insertion hole of the cover 2. Once fully inserted, the insert plate 7 pushes the first rubber tube 5 and the second rubber tube 6, bending and retracting them into the waist-shaped slot 8. This effectively seals the first and second rubber tubes 5 and 6, as well as the waist-shaped slot 8, thus sealing the first interface 3 and the second interface 4. This provides a rapid and efficient seal for the collection bottle body 1, offering fast sealing and convenient operation with high overall efficiency.
[0038] In the above operation, when the insert plate 7 is not inserted into the cover 2, the corresponding bracket 12 can be rotated so that the two bent rods 13 on the bracket 12 are respectively inserted and matched with the two notches 11. After the two bent rods 13 are matched with the two notches 11, the sliding of the two smooth rods 10 can be restricted, that is, the insert plate 7 is positioned and fixed, and the sliding of the insert plate 7 is restricted, thereby preventing the insert plate 7 from being accidentally pushed. At the same time, during the process of inserting the insert plate 7 into the cover 2, the bracket 12 can be rotated so that the two bent rods 13 disengage from the corresponding two notches 11. After the insert plate 7 is inserted into the cover 2, the bracket 12 can be reset to ensure that the two bent rods 13 are respectively inserted and matched with the two notches 11, thereby positioning and fixing the insert plate 7 at this time, ensuring the effect of squeezing and sealing the first rubber tube 5 and the second rubber tube 6.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
