Description

Technical Field

[0001] The present application belongs to the field of medical device technology, and in particular relates to a negative pressure drainage device for attracting fluid accumulation in a gastric tube. Background Art

[0002] Gastric tube effusion refers to the fluid accumulated in the stomach that is drained out through a gastric tube (such as a nasogastric tube, gastrostomy tube, etc.), which may involve digestive juices, food residues or abnormal secretions. In this case, a negative pressure drainage device is usually used to suck out gastric tube effusion, which is especially suitable for cases of excessive gastric secretion, gastric emptying disorder or postoperative gastrointestinal decompression. By continuously attracting gastric contents, the pressure in the stomach is reduced to prevent vomiting, reflux or aspiration. At the same time, medical staff can also monitor the drainage volume and nature to help assess the condition (such as bleeding, infection). It promotes the recovery of gastrointestinal function in patients, especially for patients after surgery or with intestinal obstruction.

[0003] Manual negative pressure drains (such as bullet-shaped drains) are commonly used today to aspirate fluid from gastric tubes. Negative pressure is generated by manual squeezing, and suction is performed intermittently. Due to the device's portability, it is suitable for short-term gastrointestinal decompression, home care, or temporary drainage. However, during prolonged operation, the fluid in the lumen of today's manual negative pressure drains is exposed to air for a long time, which can easily breed bacteria. This poses a certain risk of infection to the patient's gastrostomy stoma.

[0004] Therefore, the above-mentioned technical defects need to be changed urgently. Summary of the Invention

[0030] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0031] The present invention provides Figure 1 、 Figure 2 and Figure 5 As shown, a negative pressure drainage device for sucking fluid accumulated in the gastric tube 7 is used to suck fluid accumulated in the patient's gastric tube 7. The main structure of the present invention includes: a soft telescopic pump 1 and a measuring cup 2. The soft telescopic pump 1 is provided with a cavity 11 inside. The soft telescopic pump 1 is provided with an air inlet port 12 and an air outlet port 13. The air inlet port 12 and the air outlet port 13 are both connected to the cavity 11. The air inlet port 12 is used to connect to the gastric tube 7. The air inlet port 12 and the air outlet port 13 are respectively provided with a first one-way valve 121 and a second one-way valve 131. The first one-way valve 121 is unidirectional toward the cavity 11, and the second one-way valve 131 is unidirectional. The directional valve 131 is unidirectionally conductive toward the outside world, and the soft telescopic pump 1 can generate negative pressure suction through self-recovery expansion; the measuring cup 2 is detachably connected to the soft telescopic pump 1, and the measuring cup 2 is connected to the cavity 11. The measuring cup 2 is used to accommodate accumulated fluid, and a plurality of scale marks 21 are arranged on the side wall of the measuring cup 2 along a first direction, and the first direction is the length direction of the soft telescopic pump 1; wherein, at least one ultraviolet sterilization lamp 3 is provided on the soft telescopic pump 1, and the ultraviolet sterilization lamp 3 is used to irradiate the cavity 11.

[0032] It is understood that an ultraviolet (UV) sterilization lamp is a disinfection device that uses short-wave ultraviolet light (UVC, 200-280nm) to destroy the DNA / RNA of microorganisms, rendering them incapable of reproduction. It is widely used in medical treatment, food processing, water treatment, and household disinfection. Meanwhile, the specific functions of the first and second one-way valves 121, 131 in this embodiment are readily understood by those skilled in the art based on existing technologies, and the structure and working principle of the first and second one-way valves 121, 131 will not be further described herein.

[0033] It should be noted that manual negative pressure drains (such as bullet-shaped drains) are commonly used today to aspirate fluid from the gastric tube 7, generating negative pressure through manual squeezing and intermittent suction. Due to the portability of the device, it is suitable for short-term gastrointestinal decompression, home care, or temporary drainage. However, during the long-term operation of today's manual negative pressure drains, the fluid in the inner cavity is exposed to air for a long time, which can easily breed bacteria, posing a certain risk of infection to the patient's gastric tube 7 stoma.

[0034] When using the present invention, it is necessary to squeeze the soft telescopic pump 1 first. After being squeezed and contracted, the soft telescopic pump 1 generates negative pressure suction by self-recovery expansion to absorb the accumulated fluid in the gastric tube 7, and the gastric tube 7 is collected through the measuring cup 2, which is convenient for medical staff to observe the patient's fluid accumulation. At the same time, during use, the inner cavity is irradiated with an ultraviolet sterilization lamp 3 to sterilize, so as to reduce the breeding of bacteria in the inner cavity of the accumulated fluid, thereby reducing the risk of infection of the patient's wound during the collection of the accumulated fluid. In some usage scenarios, the compact structural design can also be convenient for patients to carry with them.

[0035] Further, such as Figure 3 As shown, the flexible telescopic pump 1 is equipped with several ultraviolet sterilization lamps 3, with at least one ultraviolet sterilization lamp 3 installed on the top and side walls of the flexible telescopic pump 1. It should be noted that when the ultraviolet sterilization lamps 3 illuminate the inner cavity of the flexible telescopic pump 1, they can effectively sterilize. However, obscured areas (shadow areas) cannot be illuminated by the ultraviolet sterilization lamps 3 and thus cannot achieve the sterilization effect. If the ultraviolet sterilization lamps 3 illuminate from the top of the flexible telescopic pump 1, the folded areas of the side walls of the flexible telescopic pump 1 will form shadow areas, and the sterilization effect will not be achieved. Therefore, in this embodiment, at least one ultraviolet sterilization lamp 3 is installed on the top and side walls of the flexible telescopic pump 1. The top and side walls of the flexible telescopic pump 1 can both be illuminated by the ultraviolet sterilization lamps 3, achieving a sterilization effect. Furthermore, several ultraviolet sterilization lamps 3 are evenly arranged around the side walls of the flexible telescopic pump 1, so that the side walls of the flexible telescopic pump 1 can all be illuminated by the ultraviolet sterilization lamps 3.

[0036] Further, such as Figure 3 and Figure 4As shown, the flexible telescopic pump 1 is provided with a battery 4, a circuit board 5, and at least one button 6. The battery 4, the ultraviolet sterilization lamp 3, and the button 6 are all electrically connected to the circuit board 5. The button 6 is used to turn the ultraviolet sterilization lamp 3 on and off. It is understood that the battery 4 is rechargeable and can be used repeatedly. Medical personnel can turn the ultraviolet sterilization lamp 3 on and off by pressing the button 6.

[0037] Further, such as Figure 1 and Figure 5 As shown, the air inlet port 12 is provided with a flow control valve 122 for regulating the flow rate of the air inlet port 12. It is understood that the flow control valve 122 can be used to adjust the flow rate of the air inlet port 12. When the air intake volume is too large, the single cycle time will be shortened; conversely, when the air intake volume is small, the single cycle time will be extended. Medical staff can adjust the opening of the flow control valve 122 based on the patient's actual condition. In addition, the flow control valve 122 can also close the air inlet port 12.

[0038] It is understandable that the specific functions of the flow regulating valve 122 in this embodiment can be obtained by those skilled in the art based on the existing technology, and the structure and working principle of the flow regulating valve 122 will not be described in detail here.

[0039] Further, such as Figure 1 and Figure 5 As shown, a negative pressure gauge 123 is provided on the air inlet port 12 , and the negative pressure gauge 123 is used to detect the negative pressure value in the air inlet port 12 .

[0040] It is understandable that the negative pressure gauge 123 can detect the negative pressure value in the air inlet port 12, making it convenient for medical staff to adjust the flow regulating valve 122 of the air inlet port 12 and the counterweight of the soft telescopic pump 1 so that medical staff can adjust the negative pressure suction.

[0041] It can be understood that the specific functions of the negative pressure gauge 123 in this embodiment can be obtained by those skilled in the art based on the existing technology, and the structure and working principle of the negative pressure gauge 123 will not be described in detail here.

[0042] Further, such as Figure 1 and Figure 2 As shown, the air inlet port 12 and the air outlet port 13 are both located at the top of the flexible telescopic pump 1. It will be appreciated that, in this embodiment, the placement of both the air inlet port 12 and the air outlet port 13 at the top of the flexible telescopic pump 1 allows fluid accumulated in the gastric tube 7 to enter the cavity 11 from the top of the flexible telescopic pump 1 and drip into the measuring cup 2 under the action of gravity. Furthermore, the placement of the air outlet port 13 at the top of the flexible telescopic pump 1 prevents squeezing of the flexible telescopic pump 1, allowing gas in the cavity to be discharged smoothly from the top without discharging accumulated fluid.

[0043] Further, such as Figure 1 and Figure 2 As shown, the top of the flexible telescopic pump 1 is provided with at least one lug 14, located in the middle of the upper end of the flexible telescopic pump 1. The lug 14 is used to suspend the flexible telescopic pump 1. In this embodiment, the lug 14 allows the collection end 15 provided at the bottom of the flexible telescopic pump 1 to be suspended, allowing it to expand and extend along its own height. The suspended flexible telescopic pump 1 can also utilize its own gravity to increase tension, thereby increasing the negative pressure suction of the air inlet port 12 of the flexible telescopic pump 1.

[0044] Further, such as Figure 1 and Figure 2 As shown, the bottom of the flexible telescopic pump 1 is provided with a collecting end 15, which is funnel-shaped. The measuring cup 2 is detachably connected to the bottom of the collecting end 15, and the measuring cup 2 is connected to the cavity 11 through the collecting end 15. It should be noted that after the fluid accumulated in the gastric tube 7 enters the inner cavity through the air inlet port 12, it will drip from top to bottom to the bottom of the inner cavity due to the action of gravity. In order to prevent the fluid accumulated in the gastric tube 7 from splashing onto the side walls of the inner cavity, in this embodiment, the collecting end 15 is provided at the bottom of the flexible telescopic pump 1, and the collecting end 15 is configured to be funnel-shaped. The funnel-shaped collecting end 15 can receive the fluid accumulated in the gastric tube 7 and collect it in the measuring cup 2, thereby preventing the fluid from splashing onto the side walls of the inner cavity.

[0045] Furthermore, the flexible telescopic pump 1 is expandable and retractable along a first direction. It is understood that the first direction is the height direction of the flexible telescopic pump 1, i.e., the vertical direction. When the flexible telescopic pump 1 is squeezed, it expands along its own height direction, creating a negative pressure in the cavity 11, which in turn generates a negative suction force at the air inlet port 12, thereby aspirating the accumulated fluid in the gastric tube 7.

[0046] Further, such as Figure 1 and Figure 2 As shown, a hook 16 is provided on the bottom of the flexible telescopic pump 1 , and a counterweight 161 is detachably connected to the hook 16 . The counterweight 161 is used to counterweight the bottom of the flexible telescopic pump 1 .

[0047] It is understood that since the flexible telescopic pump 1 expands along its own height, generating negative pressure in the cavity 11, a hook 16 is provided at the bottom of the flexible telescopic pump 1 in this embodiment to suspend a counterweight 161. The counterweight 161 can increase the expansion force of the flexible telescopic pump 1, thereby increasing the negative pressure suction force of the air inlet port 12 and improving the effect of aspirating the effusion. Furthermore, the counterweight 161 of different masses can be used so that medical staff can adjust the weight according to the actual situation of the patient.

[0048] In summary, the present application provides a negative pressure drainage device for attracting fluid accumulated in a gastric tube 7. When in use, the present invention requires squeezing a flexible telescopic pump 1. After being squeezed and contracted, the flexible telescopic pump 1 self-expands to generate negative pressure suction to absorb the fluid accumulated in the gastric tube 7. The gastric tube 7 is then collected through a measuring cup 2, making it convenient for medical staff to observe the patient's fluid accumulation. At the same time, during use, an ultraviolet sterilization lamp 3 is used to irradiate the inner cavity for sterilization, thereby reducing the growth of bacteria in the inner cavity and reducing the risk of infection of the patient's wound during the collection of the fluid.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
