Description

Technical Field

[0001] This utility model relates to a gastric tube opening and venting device, belonging to the field of medical device technology. Background Technology

[0002] In clinical nursing, for patients using ventilators, especially non-invasive ventilation, guidelines recommend the use of a degassing device after more than two minutes of non-invasive ventilation in order to expel gas or fluid from the stomach and reduce discomfort caused by gastric bloating. However, existing gastric tube degassing devices still have many shortcomings in their structural design.

[0003] Traditional devices often rely on simple tubing for venting, and most involve disassembling syringes for easy assembly. However, the presence of needles during assembly poses a safety hazard to nursing staff. Furthermore, when using the device after disassembling the syringe, the fixed design lacks effective control over the gas-liquid separation process, frequently leading to liquid backflow and blockage of the gas delivery path. The device also requires a fixed orientation, making it difficult to directly observe the nature of the reflux material in its current structure. When the device is full of liquid, busy nursing staff may not be able to change the fluid promptly, resulting in delayed gas venting. The overflow of reflux material can also contaminate the bed unit, requiring replacement and further increasing the workload of medical staff.

[0004] Therefore, a gastric tube opening and air release device is proposed. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and solve the problems of needle safety hazards, gas-liquid passage blockage, poor exhaust, liquid backflow, inability to observe the properties of refluxed material, and inconvenience of replacement during use.

[0006] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution: A gastric tube opening and venting device is provided, including a reservoir, with a first catheter cap and a second catheter cap for conduction connected to both ends of the reservoir, respectively. An air duct is inserted into the axis of the second duct cap, and the second duct cap includes a first support; the first support divides the internal space into multiple air chambers through the air duct and the partition inside the first support. The side wall of the air guide tube is provided with a hole, and the air guide tube is connected to the air chamber in the first support through the hole; the hole is used to transmit the gas entering at the end where the first guide tube cap is located to the end where the second guide tube cap is located through the air guide tube, and to discharge the gas through the first support. A connector is provided on the side wall of the liquid storage chamber near the second conduit cap.

[0007] Furthermore, the partitions are arranged in a ring array around the axis of the first support; In this configuration, a cylindrical space for inserting an air tube is formed at the axis of the first support through the partition, and each partition is in contact with the side wall of the air tube.

[0008] Furthermore, the holes are arranged in a ring array on the sidewall of the air guide tube and are uniformly distributed within the air cavity.

[0009] Furthermore, the second catheter cap also includes a second support, the second support having a transition cavity inside, and the side of the second support that fits with the first support having a notch, the second support allowing the transition cavity to communicate with at least one air cavity through the notch.

[0010] Furthermore, a sealing ring is connected to one end of the second support, and the second support is sleeved on the first support through the sealing ring; A rubber ring is provided between the sealing ring and the first support.

[0011] Furthermore, the first support also includes a sealing plug.

[0012] Furthermore, the length of the air guide tube is at most one-third of the length of the liquid storage chamber.

[0013] Furthermore, the first catheter cap and the second catheter cap are respectively connected to a flexible tube.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: 1. Compared with the prior art, this utility model does not require disassembling the syringe or using needles for connection, making the overall structure safer and effectively avoiding the safety hazards such as punctures to nursing staff during the assembly process of traditional devices. At the same time, by setting an air duct inside the second catheter cover and using the partition structure inside the first support to divide the space into multiple air chambers, and then using the holes on the side wall of the air duct to communicate with the air chambers, gas can be smoothly discharged and liquid can be effectively blocked, significantly reducing the risk of liquid backflow and blockage of the air duct passage.

[0015] 2. This utility model utilizes a gas-conducting tube that runs through the liquid storage chamber, with evenly distributed holes on the side wall. This fully utilizes the gas chamber structure to disperse and guide the gas, improving exhaust efficiency and preventing abdominal distension and discomfort caused by gas retention. In addition, the device has a connecting structure that keeps the liquid storage chamber in a stable vertical position during use, allowing the liquid to settle at the bottom of the chamber by gravity. Nursing staff can visually observe the nature of the refluxed material, which helps in monitoring the patient's condition and allows for timely determination of whether replacement is needed, thus preventing aspiration and nursing oversights.

[0016] 3. The present invention has a compact overall structure and a simple connection method, which facilitates quick assembly and disassembly. It is suitable for various clinical use scenarios and improves the efficiency of medical and nursing operations. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0021] like Figure 1 and Figure 2As shown, a gastric tube opening and venting device is provided, including a reservoir 1. A first catheter cap 2 and a second catheter cap 3 for conduction are respectively connected to both ends of the reservoir 1. The first catheter cap 2 and the second catheter cap 3 are respectively installed at both ends of the reservoir 1. The first catheter cap 2 is used to connect a flexible tube 6 at the gas inlet end, and the second catheter cap 3 is used to connect a flexible tube 6 at the gas outlet end. Specifically, the first catheter cap 2 and the second catheter cap 3 are respectively connected to a flexible tube 6. The flexible tube 6 at the first catheter cap 2 is directly connected to the infant's gastric tube, thereby assisting in the expulsion of gas from the infant's stomach. At the same time, a connector 5 is provided on the side wall of the liquid storage chamber 1 near the second catheter cap 3. The connector 5 is used to ensure that the first catheter cap 2 is always vertically upward, so that when liquid enters the flexible tube 6, it can be collected in the liquid storage chamber 1 by gravity, while gas can be discharged to the second catheter cap 3 through the gas duct 4. The connector 5 can be a hook or a suspension structure such as a rubber band. In this embodiment, the connector 5 is a hook.

[0022] like Figure 3 and Figure 5 As shown, an air duct 4 is inserted into the axis of the second duct cap 3. The second duct cap 3 includes a first support 31. The first support 31 divides the internal space into multiple air chambers 312 through the air duct 4 and the partition 311 inside the first support 31. The partition 311 is arranged in a ring array around the axis of the first support 31. The axis of the first support 31 forms a cylindrical space for the air duct 4 to be inserted through the partition 311, and each partition 311 is in contact with the side wall of the air duct 4.

[0023] Specifically, the interior of the first support 31 is a hollow structure, and the interior is divided into multiple air chambers 312 by the partition 311. After the air guide tube 4 is inserted into the first support 31, the side wall of the air guide tube 4 is attached to the partition 311, thereby forming an independent air chamber 312 between adjacent partitions 311. One end of the air chamber 312 is covered by the second support 32, and the other end is sealed by the first support 31 itself.

[0024] like Figure 3 As shown, the side wall of the air guide tube 4 is provided with holes 41, and the air guide tube 4 is connected to the air cavity 312 in the first support 31 through the holes 41; the holes 41 are used to transmit the gas entering at the end where the first guide cap 2 is located through the air guide tube 4 to the end where the second guide cap 3 is located, and the gas is discharged through the first support 31; the holes 41 are arranged in a ring array on the side wall of the air guide tube 4 and are evenly distributed in the air cavity 312.

[0025] In this embodiment, the holes 41 can be evenly arranged in each air cavity 312 or unevenly distributed in the air cavity 312, thereby changing the gas flow path by utilizing the gaps 322; thus, the gas flow rate can be coarsely adjusted by rotating the second support 32; for example, as Figure 5 As shown, in this embodiment, different numbers of holes 41 can be provided in different air chambers 312. The more holes 41 there are, the higher the gas flow rate in the current air chamber 312, and thus the better the exhaust effect.

[0026] It should be mentioned that, in order to prevent the hole 41 from being covered by the partition 311, the air duct 4 is non-rotatably connected to the first support 31. This can be achieved by any snap-fit ​​structure, which will not be elaborated here.

[0027] The second conduit cap 3 also includes a second support 32, which has a transition cavity 321 inside. The side of the second support 32 that is in contact with the first support 31 has a notch 322. The second support 32 allows the transition cavity 321 to communicate with at least one air cavity 312 through the notch 322. The notch 322 is set to be one, and its size is the same as the cross-section of the air cavity 312, so as to ensure that the output is the gas flow of a single air cavity 312.

[0028] A sealing ring 323 is fixedly connected to one end of the second support 32, and the second support 32 is sleeved on the first support 31 through the sealing ring 323; a rubber ring 324 is provided between the sealing ring 323 and the first support 31; the sealing ring 323 is rotatably connected to the second support 32, so that when the sealing ring 323 is sleeved on the side wall of the first support 31, a seal is achieved through the rubber ring 324, and the notch 322 can still be connected to different air chambers 312 by rotating the second support 32.

[0029] like Figure 4 As shown, the first support 31 also includes a sealing plug 313, which is used to fit tightly against the liquid storage cavity 1 to ensure connection stability.

[0030] The length of the air guide tube 4 is at most one-third of the length of the liquid storage chamber 1, such as Figure 2 As shown, in this embodiment, the length of the gas guide tube 4 within the liquid storage chamber 1 is one-third of the length of the liquid storage chamber 1. The main purpose is to ensure that gas can be discharged through the gas guide tube 4, while the liquid can be stored in the liquid storage chamber 1 by gravity. Gas will be discharged through the upper end of the gas guide tube 4 until the liquid adheres to the air inlet of the gas guide tube 4. Depending on the actual use, the air inlet of the gas guide tube 4 can be set on the side wall to further reduce the probability of liquid accidentally entering the gas guide tube 4.

[0031] In actual use, the liquid storage chamber 1 needs to be replaced. When the liquid in the liquid storage chamber 1 is about to exceed the length of the air guide tube 4, the liquid storage chamber 1 can be replaced by rotating the first guide tube cap 2 and the second guide tube cap 3. If the first guide tube cap 2 and the second guide tube cap 3 are not blocked, only the liquid storage chamber 1 needs to be replaced. Example 2:

[0032] Based on Embodiment 1, the notch 322 on the surface of the second support 32 can be set to multiple notches, and some adjacent partitions 311 can be set to a solid structure. Thus, by rotating the second support 32, the flow of gas can be adjusted more precisely.

[0033] Specifically, the notch 322 can be set to two, and the two notches 322 are symmetrically arranged. When rotating, one of the notches 322 can be connected to one of the air chambers 312, and the other notch 322 can be rotated to the other air chamber 312, or it can be fitted into the sealed air chamber 312, thereby making the adjustable gas passage range larger.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
