[0033] Example 1

[0034] Reference Figure 1-7 , which is the first embodiment of the present invention, provides a portable sputum suction device for clinical nursing, the device comprises a sputum suction component 100 and a driving component 200 installed at the rear of the sputum suction component 100,

[0035] The sputum suction assembly 100 includes a housing 101, a bottom housing 102 installed at the bottom of the housing 101, a sliding member 103 installed inside the housing 101, a connecting member 104 rotatably installed at the center of the sliding member 103, and a suction pipe 105 installed inside the connecting member 104, one end of the suction pipe 105 extends to the outer wall of the connecting member 104, and the other end of the suction pipe 105 passes through the bottom through hole of the connecting member 104 and is inserted in the middle of the bottom housing 102;

[0036] The driving assembly 200 includes a rear shell 201, an air pump 206 installed inside the rear shell 201, a main board 202 installed in the middle position inside the rear shell 201, and a rubber sleeve 203 installed at the end of the rear shell 201. The rear shell 201 is sealed and plugged into the rear end of the shell 101, and the rubber sleeve 203 is sealed and sleeved on the outside of the air outlet of the air pump 206.

[0037] Among them, a sliding member 103 with a connecting member 104 is installed inside the shell 101, and a straw 105 is inserted in the middle of the connecting member 104 for cooperating with the patient to suck sputum. The sliding member 103 is moved outward along the shell 101, so that the connecting member 104 installed in the middle of the sliding member 103 is conveniently extended, and then the straw 105 is released to perform the sputum suction operation. The sliding member 103 is moved into the shell 101. Since the connecting member 104 is installed on the inner side of the sliding member 103 through a rotating shaft, the side wall of the shell 101 will clamp the connecting member 104, so that the connecting member 104 is turned over to the inner side of the sliding member 103, and then the straw 105 is clamped between the end of the connecting member 104 and the sliding member. The position of the inner wall 103 makes the end of the suction tube 105 bend and close, isolated from the external environment to avoid cross contamination. The suction tube 105 is detachable, which is convenient for cleaning and maintenance of the suction device. A rear shell 201 with an air pump 206 is installed at the tail of the shell 101 for docking. The operation of the air pump 206 is controlled by the main board 202. The air pump 206 will compress the rubber sleeve 203 when it draws air. The rubber sleeve 203 is snapped onto the outer wall of the shell 101, which will cause negative pressure to be generated inside the shell 101. Then, suction is performed from the part where the patient needs to suck sputum through the suction tube 105, which is convenient for suction operation. The overall combined structure is small in size, easy to carry, and can be disassembled and separated for maintenance and cleaning.

[0038] Specifically, a sleeve 106 matching the rubber sleeve 203 is encapsulated in the middle of the rear end cavity of the shell 101 , and the rubber sleeve 203 is sealed and plugged into the end of the sleeve 106 .

[0039] Among them, a sleeve 106 is installed inside the shell 101 to connect with the rubber sleeve 203. When the air pump 206 inhales air, it will compress the rubber sleeve 203. The rubber sleeve 203 cooperates with the sleeve 106 to extract air from the inside of the shell 101, so that negative pressure is generated inside the shell 101 to maintain the sealing performance inside the shell 101.

[0040] Furthermore, a spring 107 is clamped on the inner wall of the sliding member 103 , and the other end of the spring 107 is connected to the inner wall of the housing 101 by means of bolts.

[0041] Among them, a spring 107 is installed on the side wall of the sliding part 103. Based on the connection with the shell 101, the spring 107 can provide a certain elastic force to the sliding part 103, so as to maintain the sliding part 103 extending from the side wall of the shell 101, and expose the suction tube 105 installed on the inner side of the sliding part 103 through the connecting part 104, so as to facilitate the suction operation.

[0042] Furthermore, the end of the sliding member 103 is connected to a plug 108 via bolts, and the side wall of the plug 108 is clamped on the outer side wall of the shell 101.

[0043] Among them, a plug 108 is installed at the end of the sliding member 103 to connect with the shell 101, and the plug 108 is clamped on the side wall of the shell 101. On the basis of the connection of the shell 101, the sliding member 103 can be limited. At this time, the inner wall of the shell 101 will clamp the connecting member 104, so that the connecting member 104 is accommodated in the middle of the sliding member 103, and then the straw 105 is clamped, the straw 105 is closed, and the straw 105 is protected to prevent the straw 105 from getting dirty. The plug 108 is pulled out, and the side wall of the sliding member 103 loses its obstruction. Under the elastic force of the spring 107, the sliding member 103 installed with the connecting member 104 can be pushed out from the inside of the shell 101 in cooperation with the shell 101, and then the straw 105 leaks out, which is convenient for suction operation.

[0044] Preferably, an extension tube 109 is clamped in the middle of the upper cavity of the shell 101 , and the end of the extension tube 109 is provided with a step edge structure matching the end of the straw 105 , and the extension tube 109 matches the inner diameter of the straw 105 .

[0045] Among them, an extension tube 109 connected to the suction tube 105 is installed inside the upper cavity of the shell 101, which is used to extend the length of the suction tube 105 to facilitate sputum suction. After suctioning, the extension tube 109 can be directly removed and discarded to reduce the contamination of the suction device by the dirty extension tube 109. The suction tube 105 can also be directly replaced according to needs.

[0046] It should be noted that a cover plate 110 is hingedly connected to the side wall of the upper cavity of the shell 101 . The cover plate 110 is located outside the extension tube 109 , and a snap-fit ​​structure matching the side wall of the shell 101 is provided on the end side wall of the cover plate 110 .

[0047] A cover plate 110 is added to the upper end of the shell 101, and the cover plate 110 is used to cooperate with the shell 101 to carry the extension tube 109 for convenient sputum suction.

[0048] Preferably, a liquid storage bag 111 is installed inside the bottom shell 102 , and an end joint of the liquid storage bag 111 is threadedly connected to the middle position of the bottom of the shell 101 .

[0049] A liquid storage bag 111 connected to the bottom of the shell 101 is installed inside the bottom shell 102. The liquid storage bag 111 is used to collect sputum, which is convenient for transferring and processing the sputum. It is easy to assemble and disassemble, and there is no need to frequently clean the sputum suction device.

[0050] Specifically, the lower end of the straw 105 extends to the center of the end joint of the liquid storage bag 111 , and one side of the sleeve 106 is connected to the liquid storage bag 111 through a pipe. The length of the side wall pipe of the sleeve 106 is less than the length of the end of the straw 105 .

[0051] Among them, the side wall pipe of the sleeve 106 extends to the top of the liquid storage bag 111. When the air pump 206 draws air, it will drive the rubber sleeve 203 to compress. The compression of the rubber sleeve 203 will draw the air inside the sleeve 106, so that negative pressure is generated inside the liquid storage bag 111, and then sputum is drawn through the straw 105. The straw 105 extends to the center of the liquid storage bag 111, and the sucked sputum is drained into the liquid storage bag 111, which is convenient for the transfer and treatment of the sputum.

[0052] Specifically, a button 204 is installed on the outer side wall of the rear housing 201 , and the button 204 contacts the switch of the mainboard 202 .

[0053] Among them, a button 204 is added on the outside of the rear shell 201 to facilitate the operation of the suction device to be controlled from the outside of the rear shell 201. The function corresponding to the button 204 can be adjusted through the pre-made program of the main board 202, such as turning on, adjusting the gear and running, etc.

[0054] Furthermore, a battery 205 is encapsulated inside the rear housing 201 , and the battery 205 is electrically connected to the mainboard 202 via a wire.

[0055] Among them, a battery 205 is installed inside the rear shell 201 and connected to the main board 202, which is convenient for maintaining the stable operation of the main board 202 and the air pump 206. A charging board can also be installed inside the rear shell 201 as needed, and the battery 205 can be replaced with a rechargeable battery, which is more convenient to carry out and extend the operation time of the suction device.

[0056] In summary, a sliding member 103 with a connecting member 104 is installed inside the housing 101, and a suction tube 105 is inserted in the middle of the connecting member 104 for cooperating with suctioning sputum from the patient. The sliding member 103 is moved outward along the housing 101, so that the connecting member 104 installed in the middle of the sliding member 103 is conveniently extended, and then the suction tube 105 is released to perform the suction operation. The sliding member 103 is moved into the housing 101. Since the connecting member 104 is installed on the inner side of the sliding member 103 through a rotating shaft, the side wall of the housing 101 will clamp the connecting member 104, so that the connecting member 104 is turned over to the inner side of the sliding member 103, and then the suction tube 105 is clamped between the end of the connecting member 104 and the sliding member 10 3, the position of the inner wall makes the end of the suction tube 105 bend and close, isolated from the external environment to avoid cross contamination, and the suction tube 105 is detachable, which is convenient for cleaning and maintenance of the sputum suction device. The rear shell 201 with an air pump 206 is installed at the tail of the shell 101 for docking, and the air pump 206 is controlled by the main board 202. The air pump 206 will compress the rubber sleeve 203 when it is pumped, and the rubber sleeve 203 is snapped on the outer wall of the shell 101, which will cause negative pressure inside the shell 101, and then the suction tube 105 is used to suction sputum from the part where the patient needs to suck sputum, which is convenient for suction operation, and the overall combined structure is small in size, easy to carry, and can be disassembled and separated for maintenance and cleaning. 03 end is connected with the shell 101 by installing a plug 108, and the plug 108 is clamped on the side wall of the shell 101.
