Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a sputum suction device specially designed for young children. Background Art

[0002] In clinical nursing of children, suctioning is a key step in maintaining airway patency and ensuring the patient's normal respiratory function. However, existing suction devices are mostly designed based on the physiological characteristics of adults, which can hardly meet the special needs of young children, especially infants and young children. The respiratory tract structure of young children is small and the mucous membrane is delicate. The suction tube size and suction setting of adult suction devices can easily cause respiratory tract damage, mucosal bleeding, and even cause serious complications such as laryngeal edema. In addition, adult suction devices are large in size and inconvenient to operate. They are difficult to adapt to the characteristics of young children who are active and difficult to cooperate, which increases the difficulty and risk of operation. At the same time, existing suction devices lack humanized designs for young children, which can easily cause fear and crying in children, and some designs have problems with incomplete cleaning and disinfection, which increases the risk of infection.

[0003] Currently, there are some sputum aspirators designed specifically for children, such as the pediatric sputum aspirator disclosed in patent publication number CN104288847B. This device has a simple structure and is easy to use. When clearing sputum from pediatric patients, it is easy to operate and has a good suction effect, which reduces the workload of medical staff. However, the working logic of this device has not been further effectively improved for pediatric patients. It is unable to minimize the suction force of the aspirator to protect the child's respiratory tract while ensuring a good suction effect. Therefore, there is a need for a sputum aspirator designed specifically for young children to address the shortcomings of the existing technology and has important clinical significance and social value. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention designs a special suction device for young children. The device reduces the possibility of wear on the child's respiratory tract by setting a spherical head at the front end of the suction tube; at the same time, a suction port is set on one side of the spherical head. With the cooperation of the main unit, the suction tube can rotate during operation, so that the suction port can perform accurate and comprehensive suction operations on the side walls of the respiratory tract. At the same time, the traditional vertical through-type suction port of the suction tube needs to ensure a certain large suction force to attract sputum on the side walls of the respiratory tract. The suction port of the present invention can accurately suck sputum, and the distance between the suction port and the side walls of the respiratory tract is closer, so the suction force required by the device is less than that of the traditional suction device, thereby greatly improving the safety of the device and reducing damage to the child's respiratory tract.

[0005] In order to achieve the above technical effects, the present invention discloses a sputum suction device for young children, comprising: a sputum suction tube, a main unit, and a collection tank; the sputum suction tube is detachably connected to the front end of the main unit; the collection tank is detachably connected to the middle part of the main unit;

[0006] Furthermore, the main unit includes: a locking bolt, a synchronization shaft, a driving chamber, a first gear, a second gear, a motor, a driving handle, a telescopic rod, and a negative pressure generator;

[0007] The locking bolt is threadedly connected to the synchronization shaft; the synchronization shaft is rotatably installed inside the driving chamber; the first gear is fixedly arranged on the outside of the synchronization shaft; the second gear is fixedly connected to the motor output shaft; the first gear is meshed with the second gear; the motor is fixedly installed inside the driving handle; the driving handle is fixedly arranged at the end of the driving chamber; one end of the telescopic rod is fixedly connected to the telescopic rod; the other end of the telescopic rod is fixedly connected to the negative pressure generator;

[0008] Furthermore, the interior of the suction tube is hollow; the top of the suction tube is fixedly provided with a spherical head; a suction port is fixedly provided on one side of the spherical head; and a synchronization block is fixedly provided on the outer wall of the other end of the suction tube;

[0009] Furthermore, a liquid inlet is fixedly provided at one end of the collection tank; a negative pressure port is fixedly provided at the other end of the collection tank; the liquid inlet is threadedly connected to the end of the driving chamber; the negative pressure port is detachably connected to the negative pressure generator;

[0010] Furthermore, a synchronization groove is fixedly provided inside the synchronization shaft; the synchronization block of the sputum suction tube is detachably installed inside the synchronization groove;

[0011] Furthermore, a button is fixedly provided on the outside of the driving handle; the button is electrically connected to the motor and the negative pressure generator.

[0012] The beneficial effects of the present invention are:

[0013] The present invention discloses a special suction device for young children. First, by providing a spherical head at the front end of the suction tube, the device can effectively reduce the wear of the suction tube on the inner wall when entering the child's respiratory tract, reduce the risk of respiratory mucosal damage caused by the suction operation, and thus alleviate the child's discomfort during the suction process. Secondly, the suction port is provided on one side of the spherical head, and cooperates with the rotation drive function of the main unit, so that the suction port can perform accurate and comprehensive suction operations on the side wall of the respiratory tract. Compared with traditional suction devices, this design can more effectively clear the sputum in the respiratory tract and avoid problems such as respiratory obstruction caused by incomplete suction. At the same time, because the suction port is closer to the side wall of the respiratory tract and the suction operation is more precise, the suction force required by this device when suctioning is significantly less than that of traditional suction devices. This not only reduces the negative pressure damage to the child's respiratory tract, but also improves the safety of the suction process and reduces the risks of airway mucosal damage, bleeding, etc. that may be caused by excessive suction. In addition, the suction tube and collection tank of this device also adopt a detachable connection method, which makes it convenient for medical staff to disinfect and replace the suction tube, as well as clean and maintain the collection tank, further improving the practicality and hygiene of the device.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1

[0023] The present invention discloses a special sputum suction device for young children, Figures 1 to 4 The device consists of a suction tube 1, a main unit 2, and a collection tank 3. The suction tube 1 is detachably connected to the front end of the main unit 2, making it easy to replace and clean, ensuring hygienic use. The collection tank 3 is detachably connected to the middle of the main unit 2, facilitating sputum collection and subsequent cleaning.

[0024] The main unit 2 is the core part of the entire device and includes components such as a locking bolt 201, a synchronous shaft 202, a drive chamber 203, a first gear 204, a second gear 205, a motor 206, a drive handle 207, a telescopic rod 208 and a negative pressure generator 209. The locking bolt 201 is connected to the synchronous shaft 202 by a threaded connection and is used to fix the position of the suction tube 1 to ensure its stable operation. The synchronous shaft 202 is rotatably mounted inside the drive chamber 203 and can rotate inside the drive chamber 203. The first gear 204 is fixedly arranged on the outside of the synchronous shaft 202 and meshes with the second gear 205. The second gear 205 is fixedly connected to the output shaft of the motor 206. When the motor 206 is started, it drives the synchronous shaft 202 to rotate through a gear transmission. The motor 206 is fixedly mounted inside the drive handle 207, and the drive handle 207 is fixedly arranged at the end of the drive chamber 203, providing stable support for the motor 206. One end of the telescopic rod 208 is connected to the sputum suction tube 1, and the other end is fixedly connected to the negative pressure generator 209. The telescopic movement of the telescopic rod 208 can facilitate the fixation of the collection canister 3 and make it easier for the negative pressure generator 209 to connect to the collection canister 3. The negative pressure generator 209 provides the necessary negative pressure environment for the entire sputum suction process, ensuring that sputum can be smoothly sucked out.

[0025] The interior of the suction tube 1 is a hollow structure, with a spherical head 101 fixed at the top. This unique design can effectively reduce the wear of the suction tube 1 on the inner wall of the respiratory tract when entering the child's respiratory tract, reducing the child's discomfort. A suction port 102 is fixedly provided on one side of the spherical head 101, which is used to directly contact and suck out sputum in the respiratory tract. A synchronization block 103 is fixedly provided on the outer wall of the other end of the suction tube 1. The synchronization block 103 cooperates with the synchronization shaft 202 in the main unit 2, allowing the suction tube 1 to rotate under the drive of the main unit 2, thereby achieving a full range of suction effects.

[0026] Collection tank 3 is fixedly provided with a liquid inlet 301 at one end and a negative pressure port at the other. Liquid inlet 301 is threadedly connected to the end of drive chamber 203, ensuring smooth flow of sputum into collection tank 3. The negative pressure port is connected to negative pressure generator 209 in a detachable manner, allowing for easy disassembly and cleaning when needed.

[0027] In addition, a synchronization groove 2010 is fixedly provided inside the synchronization shaft 202, and the synchronization block 103 of the sputum suction tube 1 can be detachably installed inside the synchronization groove 2010, thereby ensuring a stable connection between the sputum suction tube 1 and the host 2.

[0028] Finally, a button 2011 is fixedly mounted on the outside of the driving handle 207. This button 2011 is electrically connected to the motor 206 and the negative pressure generator 209. By pressing the button 2011, medical personnel can start and stop the motor 206, thereby controlling the rotation of the suction tube 1. This also controls the working state of the negative pressure generator 209, adjusting the negative pressure to meet different suction needs.

[0029] The working principle and usage process of this device are as follows:

[0030] In terms of working principle, the core of this device is to realize the rotation function of the suction tube 1 through the drive of the motor 206 of the main unit 2, thereby improving the suction effect and reducing damage to the child's respiratory tract. Specifically, the motor 206 in the main unit 2 drives the synchronous shaft 202 to rotate through gear transmission, and the synchronous block 103 of the suction tube 1 is installed in the synchronous groove 2010 of the synchronous shaft 202, so that the suction tube 1 can rotate with the rotation of the synchronous shaft 202. The spherical head 101 at the front end of the suction tube 1 is designed to reduce the wear on the inner wall of the child's respiratory tract, and the suction port 102 on one side can accurately contact the side wall of the respiratory tract during rotation, realizing a full range of suction operations. Because the suction port 102 is closer to the side wall of the respiratory tract and can be accurately positioned, the suction force required by the device is less than that of a traditional suction device, thereby reducing the risk of damage to the child's respiratory tract. At the same time, the negative pressure generator 209 in the main unit 2 is connected to the suction tube 1 through the collection tank 3, providing a stable negative pressure environment for the suction operation. The sputum enters the suction tube 1 through the suction port 102 and flows into the collection tank 3. The liquid inlet 301 of the collection tank 3 is connected to the end of the drive chamber 203, and the negative pressure port is connected to the negative pressure generator 209, ensuring that the sputum can be collected and stored smoothly.

[0031] In terms of the usage process, preparation work is first required, including checking whether the various components of the device are firmly connected, disinfecting the spherical head 101 and the suction port 102 at the front end of the suction tube 1, cleaning and disinfecting the collection tank 3 to ensure that the interior is sterile, and then installing the synchronization block 103 of the suction tube 1 into the synchronization groove 2010 of the synchronization shaft 202 of the main unit 2, and tightening the locking bolt 201 to the synchronization shaft 202 to fix the suction tank, and finally threading the liquid inlet 301 of the collection tank 3 to the end of the drive compartment 203, and the negative pressure port is detachably connected to the negative pressure generator 209. Next, the suction operation stage is entered. Press the button 2011 on the driving handle 207 to start the motor 206 and the negative pressure generator 209. The motor drives the suction tube 1 to rotate. The negative pressure generator 209 provides a stable negative pressure environment for the suction operation. The spherical head 101 at the front end of the suction tube 1 is gently inserted into the child's respiratory tract. Since the design of the spherical head 101 can reduce the wear on the inner wall of the respiratory tract and reduce the child's discomfort, after the suction tube 1 is inserted into the respiratory tract, the motor drives the suction tube 1 to rotate so that the suction port 102 can contact the side wall of the respiratory tract in all directions and accurately remove sputum. Medical staff should closely observe the child's reaction during the suction process. If coughing, difficulty breathing, etc. occur, the operation should be suspended immediately and the position or depth of the suction tube 1 should be adjusted to ensure the safety and effectiveness of the suction operation. When the sputum is cleared, stop the operation of the motor and the negative pressure generator 209, gently remove the suction tube 1 from the child's respiratory tract to avoid unnecessary irritation to the respiratory tract, pour out the sputum in the collection tank 3 and clean and disinfect it, remove the suction tube 1 and disinfect it or discard it directly, and properly store the main unit 2 for next use.
