Description

Technical Field

[0001] The utility model belongs to the technical field of nursing equipment, in particular to a portable sputum suction device. Background Art

[0002] Aspirators are primarily used to help patients clear airway secretions, such as sputum. They are widely used in clinical practice, especially in the treatment of respiratory illnesses, where their importance cannot be ignored. They operate by generating negative pressure to draw secretions from the airway and restore airway patency.

[0003] Suction pumps come in two types: manual and electric. Manual suction pumps are suitable for simple cleaning, while electric suction pumps provide continuous, stable negative pressure and are more suitable for critically ill patients. Manual suction pumps are low-cost and generally used in home care, while electric suction pumps are generally used in hospital intensive care units.

[0004] Manual sputum suction pumps are relatively small, lightweight, and easy to carry. Currently, commercially available sputum suction pumps consist of three main parts: a storage bottle, an intermediate tube, and a negative pressure driver. The storage bottle is screwed onto the bottom of the intermediate tube, the negative pressure driver is connected to the rear end of the intermediate tube, and the front end of the intermediate tube is connected to a suction hose. By operating the negative pressure driver, negative pressure is generated in the intermediate tube, and sputum is then drawn into the storage bottle through the suction hose and intermediate tube.

[0005] Currently, the negative pressure drive for sputum suction devices generally uses a gun-type structure, which generates suction force through a reciprocating, unidirectional motion. However, this type of suction device is still bulky and lacks portability. Furthermore, the storage bottle of current sputum suction devices is bulky and requires regular cleaning. Utility Model Content

[0006] In view of the above problems, the purpose of the present invention is to provide a portable sputum suction device to solve the above technical problems.

[0007] The utility model adopts the following technical solutions:

[0008] The portable sputum suction pump includes a storage bottle and a top cover, the top cover is screwed to the storage bottle, the side wall of the storage bottle is recessed inward to form an air cavity, the air cavity is provided with an expansion balloon, the air cavity is provided with an air inlet one-way valve and an air outlet one-way valve, the air inlet one-way valve is connected to an air inlet pipe, and the air outlet one-way valve is connected to an air outlet pipe, the ends of the air inlet pipe and the air outlet pipe are both led out of the side wall of the storage bottle, the top cover is provided with a conduit, the end of the conduit extends into the top cover, and the top cover is also provided with a connecting short tube, and the short tube is connected to the end of the air inlet pipe through a detachable hose.

[0009] Furthermore, the conduit is arranged transversely, and the end of the conduit is bent downward to form a bent portion, and the bent portion faces the external space of the air cavity.

[0010] Furthermore, a retaining ring is provided in the middle of the top cover, the bottom port of the bent portion is located below the retaining ring, and the short tube is provided above the retaining ring.

[0011] Furthermore, one end of the hose is provided with a connector, and the connector is used for plugging with the short tube.

[0012] Furthermore, a filter is provided in the middle of the hose.

[0013] The beneficial effects of this utility model are as follows: First, this product uses a relatively small balloon as a negative pressure driver. Pressing the balloon generates negative pressure, thereby completing sputum absorption. Second, by designing the structure of the storage bottle, a concave area is formed on the side wall to form an air cavity, and then an inflatable balloon is provided, thereby combining the balloon with the storage bottle, further reducing the volume of the product. Third, the balloon and the top cover are connected by a hose. First tighten the top cover, then connect the hose, which is also relatively simple to operate. Compared with existing products, this product is more convenient to carry and package, and has a lower cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a cross-sectional view of a portable sputum suction device provided by an embodiment of the present utility model;

[0015] Figure 2 This is a partial enlarged view of the top cover position. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0018] like Figure 1-2As shown, the portable sputum suction pump provided in this embodiment includes a storage bottle 1 and a top cover 2, the top cover 2 is screwed to the storage bottle 1, the side wall of the storage bottle 1 is recessed inward to form an air cavity 3, the air cavity 3 is provided with an expansion balloon 4, the air cavity 3 is provided with an air inlet check valve 31 and an air outlet check valve 32, the air inlet check valve 31 is connected to an air inlet pipe 33, and the air outlet check valve 32 is connected to an air outlet pipe 34, the ends of the air inlet pipe 33 and the air outlet pipe 34 are both led out of the side wall of the storage bottle 1, the top cover 2 is provided with a conduit 21, the end of the conduit 21 extends into the top cover 2, and the top cover 2 is also provided with a connecting short tube 22, and the short tube 22 is connected to the end of the air inlet pipe 33 through a detachable hose 5.

[0019] This structure uses an inflatable balloon as a negative pressure driver. The inflatable balloon has applications in other fields, such as negative pressure drainage, and can also be used for inflation. The inflatable balloon has two ports, one for air inlet and one for air outlet. Both ports are equipped with one-way valves, which are generally diaphragms, low in cost, and widely used. By pressing the inflatable balloon, gas is discharged from the air outlet port. After releasing it, the inflatable balloon automatically resets and air is taken in by the air inlet port. Reciprocating pressing can achieve the function of negative pressure drainage or inflation. The volume of the inflatable balloon is smaller than that of conventional negative pressure drivers used for suction pumps, making the product easy to carry and package.

[0020] Another design feature of this structure is the integration of the expansion balloon and the storage bottle. The size of the storage bottle can be the same as in existing designs. However, this embodiment incorporates a recessed area in the sidewall of the storage bottle to form an air cavity, within which the expansion balloon is placed, effectively integrating the balloon and the storage bottle. While the internal volume of the storage bottle is reduced, the amount of sputum suctioned is limited, particularly for pediatric patients, and a larger volume is not required. Therefore, this embodiment integrates the two into one structure through the structural design of the air cavity, further reducing the product's size.

[0021] This embodiment does not limit the specific combination method. In the figure, the expansion balloon is sealed at the external opening position of the air cavity. Of course, a complete balloon can also be placed at the air cavity position. When in use, the catheter is connected to the suction hose, and the end of the suction hose is placed at the throat. The operation can be performed by pinching the storage bottle with one hand. When the balloon is pressed, the air inlet one-way valve at the top automatically closes, and the air outlet one-way valve at the bottom automatically opens, and the internal air is discharged from the air outlet pipe, and the hand will not block the port of the outlet pipe. When the balloon is released, the air outlet one-way valve automatically closes, and the air inlet one-way valve automatically opens, and the gas is extracted from the bottle, and the bottle is under negative pressure. Continuous pressing is used to absorb sputum through the suction hose.

[0022] In order to prevent sputum from being adsorbed onto the short tube on the top cover during operation, in this structure, the conduit 21 is arranged horizontally, and the end of the conduit 21 is bent downward to form a bent portion 23, and the bent portion 23 faces the external space of the air cavity 3. The storage bottle is divided into three parts, the diameter of the middle part is smaller than the upper and lower parts, and the bent portion is downward and facing the middle part, so that the sputum can fall directly into the lower space. In addition, there is a circle of retaining ring 24 in the middle part of the top cover 2, and the bottom port of the bent portion 23 is located below the retaining ring 24, and the short tube 22 is located above the retaining ring 24. The short tube is arranged away from the bent portion to further avoid this problem. In addition, the function of the retaining ring here is to limit the bottle mouth and maintain sealing.

[0023] When the top cover is tightened, the top cover is in the same direction, so the short tube and the end of the air inlet pipe 33 are basically on the same side. One end of the hose 5 also has a connector 51, which is used to plug into the short tube 22 for easy operation. In addition, the middle of the hose 5 also has a filter 6, which can filter the gas in the bottle and reduce pollution to a certain extent.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
