Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to a rapid and safe sputum suction device for internal medicine. Background Technology

[0002] In clinical internal medicine, sputum suctioning is a crucial method for clearing airway secretions and maintaining airway patency. However, traditional suction devices pose significant risks during use: when the suction catheter is inserted into the airway through the mouth, it temporarily obstructs the airway, causing transient respiratory arrest. This is especially dangerous for elderly, frail, or unconscious patients, as such apnea can easily lead to serious complications such as hypoxemia and arrhythmias, potentially even life-threatening. Furthermore, existing suction devices lack effective technical measures to ensure patient respiratory safety during operation, making it difficult for healthcare professionals to maintain oxygen supply while suctioning. Therefore, there is an urgent need to develop a new type of suction device that can ensure unobstructed breathing and reduce operational risks during suctioning to meet the clinical needs for safe and efficient treatment.

[0003] Based on the above, traditional suction devices can cause respiratory interruption in patients due to airway obstruction caused by the insertion of the suction tube into the mouth. This can easily lead to serious complications in patients who are weak or have poor cardiopulmonary function, and existing equipment lacks respiratory safety measures. Therefore, developing a new type of rapid and safe suction device for internal medicine that can ensure unobstructed breathing and reduce operational risks during suctioning is of significant clinical importance.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example

[0021] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a rapid and safe suction device for internal medicine, including a layer tube 1, a liquid tube 2, a three-way head 3, a liquid tank 6, an air connector 7, a connecting head 101, a suction head 102, and an air bend 701; a set of annular connectors is provided on one side of the layer tube 1, and a set of annular grooves is provided on one side of the bottom of the connecting head 101, with the bottom of the connecting head 101 being tightly connected to one side of the layer tube 1; a set of circular holes is provided on one side of the connecting head 101, and the suction head 102 is tightly connected to the circular holes on one side of the connecting head 101; a set of annular connectors is provided on one side of the liquid tube 2. The liquid pipe 2 is fastened to one side of the layer pipe 1 in a circular hole; the air bend pipe 701 is provided with a set of clamping heads on one side, and the clamping heads on the air bend pipe 701 are clamped to the semi-circular hole at the tail of the layer pipe 1; the air connector 7 is clamped to one side of the air bend pipe 701; the bottom of the three-way head 3 is provided with a set of circular holes, the upper outer side of the liquid tank 6 is provided with threads, and the upper part of the liquid tank 6 is fastened to the bottom of the three-way head 3; the three-way head 3 is provided with a set of air pumps 4 on one side; the tail of the air pump 4 is provided with a set of circular holes, and a handle 5 is telescopically connected in the circular holes at the tail of the air pump 4.

[0022] The connecting tube 101 has three sets of circular holes at its lower part, and these circular holes are connected to the semi-circular holes at the lower part of the laminar tube 1. The suction head 102 is connected to the upper circular hole of the laminar tube 1 through the connecting tube 101. The three sets of circular holes at the lower part of the connecting tube 101 are connected to the semi-circular holes at the lower part of the laminar tube 1, forming an independent ventilation channel. This allows outside air to continue flowing in while the suction head 102 is inserted into the airway to suction sputum, effectively preventing the patient's breathing from being obstructed. At the same time, this design ensures that suctioning and ventilation functions do not interfere with each other. While maintaining the patient's breathing patency, it ensures that the suction head 102 can stably suction sputum through the circular holes at the upper part of the connecting tube 101 and the laminar tube 1, greatly improving the safety and effectiveness of the suctioning operation.

[0023] The liquid tube 2 is securely connected to a connector 201 on one side, and the connector 201 is snapped into the circular head of the three-way head 3. This snap-fit ​​connection between the connector 201 and the three-way head 3 allows for quick assembly and disassembly of the liquid tube 2 and the core tubing system of the suction device. During use, this connection method ensures that sputum flows steadily into the liquid tank 6 through the liquid tube 2, preventing leakage. When the liquid tank 6 needs cleaning or replacement, medical staff can easily separate the connector 201 from the three-way head 3 to quickly complete the subsequent processing. This improves the continuity of the suctioning operation, facilitates equipment maintenance, and enhances the convenience and practicality of the suction device.

[0024] The three-way head 3 is connected to the air pump 4. An air plate 401 is movably connected inside the air pump 4. This connection between the three-way head 3 and the air pump 4 provides a transmission channel for the suction force generated by the air pump 4, ensuring that the suction force is precisely applied to the suction tubing. The air plate 401 inside the air pump 4 is flexible. Medical staff can move the air plate 401 back and forth within the air pump 4 by pushing or pulling the handle 5 at the rear of the air pump 4, thus achieving the inhalation and exhalation process. This structure not only generates suction as needed to draw sputum through the tubing into the liquid tank 6, but also allows for flexible adjustment of the suction force by controlling the frequency and amplitude of the air plate 401's movement, meeting the suction needs of different patients and improving the safety and effectiveness of suctioning procedures.

[0025] The air plate 401 has a set of circular grooves on one side, which are securely connected to the handle 5, forming a stable power transmission structure. When medical staff hold the handle 5 and push or pull, this connection drives the air plate 401 to move precisely within the air pump 4, efficiently converting the force applied by the hand into the suction force required for sputum suction. This tight connection not only ensures stable force transmission during operation and prevents the air plate 401 from detaching from the handle 5, but also allows medical staff to more flexibly and precisely control the stroke of the air plate 401 according to the actual sputum suction situation, thereby effectively adjusting the suction force and ensuring the safety and efficiency of the sputum suction operation.

[0026] The air pump 4 has an annular groove on its rear side, and a spring 402 is fitted into the annular groove on one side of the air plate 401 and the annular groove on the rear side of the air pump 4. The annular groove on the rear side of the air pump 4 and the annular groove on the side of the air plate 401 together provide installation space for the spring 402, forming an elastic reset structure. When the medical staff pulls the handle 5, the air plate 401 moves backward against the elastic force of the spring 402, and a negative pressure is formed in the air pump 4 to generate suction. When the handle 5 is released, the spring 402, with its own elastic deformation restoring force, pushes the air plate 401 to quickly reset, so that the air pump 4 completes one inhalation-exhalation cycle. This design not only realizes the automatic reset of the air pump 4, reducing the operating burden of medical staff, but also ensures the continuous and stable suction during sputum suction through the stable elastic output of the spring 402, improving the efficiency and safety of sputum suction.

[0027] The specific usage and function of this embodiment are as follows: In this invention, during use, medical personnel first connect the air connector 7 to the end of the laminar flow tube 1 via the air bend 701 to ensure unobstructed gas flow. Then, the liquid tube 2 is connected to the three-way connector 3 via the connector 201, allowing the liquid container 6 to store sputum. During operation, the handle 5 is held, and suction is generated manually by the cooperation of the air plate 401 and spring 402 inside the air pump 4. The suction is transmitted through the three-way connector 3 and the liquid tube 2 to the laminar flow tube 1, and then through the connecting tube 101 to the suction head 102, thus achieving sputum aspiration. Because the lower circular hole of the connecting tube 101 is connected to the lower semi-circular hole of the laminar flow tube 1, outside air can enter the laminar flow tube 1 through the air connector 7 and the air bend 701 during suctioning, and flow into the patient's mouth through the lower hole of the connecting tube 101, preventing respiratory interruption when the suction head 102 obstructs the airway and effectively ensuring respiratory safety. Sputum is passed through the suction head 102, connecting tube head 101, layer tube 1, and liquid tube 2, and finally stored in the liquid tank 6 for convenient subsequent processing. The manual operation of the air pump 4 also allows medical staff to flexibly control the suction power according to the patient's condition. The entire device has a compact structure and coordinated functions, which can reduce the patient's respiratory risk while achieving rapid sputum suction.
