Description

Technical Field

[0001] This invention pertains to gastric tubes, specifically referring to an integrated device for neonatal tube feeding and drainage. Background Technology

[0002] Because newborns are prone to bloating during tube feeding and gastric fluid needs to be collected, a gastric tube that combines tube feeding, drainage, and decompression functions is required to reduce the irritation of the newborn's esophagus during tube placement.

[0003] The existing publication CN113058137A proposes a neonatal double-lumen gastric tube, such as Figure 1 As shown in state one, two channels are set in the gastric tube. When tube feeding is performed, the first channel and the second channel are isolated by a sliding plug. Milk enters through the first channel and enters the newborn's stomach through the first through hole at the end. At the same time, gas in the stomach can enter through the second through hole and exit through the second channel.

[0004] Figure 2 The second state of decompression was demonstrated, in which the sliding plug was pulled upward by the traction line to connect the second through hole and the first channel, and negative pressure was connected through the first connector to perform gastrointestinal decompression;

[0005] Switching from state one to state two requires pulling the traction line upwards, while switching from state two to state one requires squeezing the guide wire inwards. Switching between the two states requires overcoming sliding blockage and friction between the inner walls of the second channel, which makes it impossible to switch between the two states quickly. Therefore, a tube feeding and drainage integrated device is needed that can achieve the above-mentioned tube feeding, gas expulsion and gastrointestinal decompression functions and can quickly switch states. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated device for neonatal tube feeding and drainage to solve the above-mentioned technical problems.

[0007] A neonatal tube feeding and drainage integrated device includes an intermediate tube body, which is composed of a first channel and a second channel that are independent of each other;

[0008] An external connector, comprising a first connector and a second connector; and a distal connector disposed at the distal end of the intermediate tube body, the distal connector covering and fixing the ends of the first channel and the second channel, wherein one end of the first channel communicates with the interior of the distal connector and the other end communicates with the first connector, one end of the second channel communicates with the interior of the distal connector and the other end communicates with the second connector, and the first channel and the second channel located on one side of the external connector are not connected to each other to avoid flow path interference;

[0009] The distal connector and channel are provided with a first through hole and a second through hole for communicating with the stomach cavity;

[0010] It is also equipped with a state-switching sealing component, which allows the device to close the second channel in the first state to allow gastric gas to be released during feeding, and to connect the first channel and the second channel in the second state to allow gastric fluid to be aspirated.

[0011] Furthermore, in the first state, the milk enters the first channel through the first connector and enters the stomach through the first through hole, while the second through hole guides the gas in the stomach into the second channel and discharges it through the second connector.

[0012] Furthermore, in the second state, after the second connector is closed, the first channel and the second channel are interconnected. When the first connector is connected to the negative pressure tube, the gastric contents that enter the covered head through the first through hole and the second through hole are drawn out along the first channel.

[0013] Furthermore, the state-switching sealing assembly includes a ball valve that can move under gravity or traction, the ball valve sealing the distal end of the second channel in the first state.

[0014] Furthermore, the state-switching sealing assembly also includes a traction rope, which is pulled outward in the first state to keep the ball blocking the second channel, and relaxed in the second state to allow the two channels to connect.

[0015] Furthermore, the first through hole is disposed on the side wall of the covering head, and the second through hole is disposed on the side wall of the second channel and located in the middle section of its side wall.

[0016] Furthermore, the second connector remains open during feeding to allow unobstructed venting.

[0017] Furthermore, the first connector is equipped with a first cover for sealing in the non-working state, and the second connector is equipped with a second cover for sealing before suction.

[0018] Furthermore, another embodiment of the state switching sealing assembly is a state switching head disposed inside the covering head and connected to the distal end of the second channel, wherein the end of the state switching head is a blocking part and its side wall is provided with a third through hole.

[0019] Furthermore, in the first state, the blocking part is close to the inside of the second channel to isolate the two channels. In the second state, an air gap is formed between the blocking part and the second channel. The air gap and the third through hole connect the first channel and the second channel to facilitate the extraction of gastric juice.

[0020] The beneficial effects achieved by the present invention using the above structure are as follows:

[0021] The device features a switchable dual-channel flow path for feeding, venting, and suction. In feeding mode, milk and gas flow separately, avoiding mutual obstruction and crossflow of gas and liquid, reducing the risk of bloating, reflux, and aspiration. Switching between modes is simple, quick, and effortless. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] This invention proposes an integrated device for neonatal tube feeding and drainage, such as... Figure 3 , Figure 4 As shown;

[0036] It includes an intermediate tube 1, which consists of two tubes, one for venting and the other for tube feeding and gastric fluid extraction.

[0037] External connector 2 includes a first connector 201 and a second connector 202;

[0038] The first connector 201 is used to connect milk during feeding and to apply negative pressure when extracting gastric juice to draw the gastric juice out of the stomach.

[0039] The second connector 202 is used to expel gas from the stomach in the first state, i.e. when feeding, and to connect to a negative pressure pipe in the second state, i.e. when extracting gastric juice.

[0040] And a distal connector 3 connected to the end of the intermediate pipe body 1, the distal connector 3 covering the heads of the two pipes of the intermediate pipe body 1 and forming a fixation;

[0041] One end of the first channel 101 is connected to the interior of the remote connector 3, and the other end is connected to the first connector 201;

[0042] One end of the second channel 102 is connected to the interior of the remote connector 3, and the other end is connected to the second connector 202;

[0043] It should be noted that the ends of the first channel 101 and the second channel 102 located inside the external connector 2 are not connected to each other, in order to prevent the milk entering from the outside and the gas expelled from the stomach from interfering with each other.

[0044] like Figure 5 As shown;

[0045] In the first state, the milk enters the first channel 101 through the first connector 201;

[0046] At this time, the ball stopper 104 is located at the end of the second channel 102, which closes the second channel 102. When the milk enters the stomach, the gas in the stomach enters the second channel 102 through the second through hole 103 and reaches the second connector 202 through the second channel 102.

[0047] The first through hole 302 is located on the side wall of the covering head 301;

[0048] The second through hole 103 is located on the side wall of the second channel 102;

[0049] The second through hole 103 should be opened on the middle section of the side wall of the second channel 102;

[0050] When inserting a gastric tube, care should be taken not to insert an excessive amount of the tube, causing it to accumulate in the stomach. This would result in the first through-hole 302 and the second through-hole 103 being below the liquid in the stomach when milk is being fed. During the feeding of milk, the first through-hole 302 would receive the milk, while at the same time the milk would be discharged through the second through-hole 103 from the second channel 102.

[0051] It is also important to note that the opening of the second connector 202 needs to remain open at this time to allow gas in the stomach to be discharged without obstruction.

[0052] In this state, the opening of the second connector 202 opens outward, and the traction rope 105 is pulled outward to keep the ball blocker 104 blocking the second channel 102.

[0053] like Figure 6 As shown;

[0054] In the second state, when it is necessary to extract gastric fluid, the second connector 202 needs to be sealed with the second cover 204 first.

[0055] The ball 104 falls into the interior of the distal connector 3, and at the same time, the first channel 101 and the second channel 102 are connected;

[0056] At this time, the first connector 201 is connected to the negative pressure tube, and the gastric juice will enter the covering head 301 from the first through hole 103 and the second through hole 30, and then be drawn out after passing through the first channel 101 to the first connector 201.

[0057] When there is no need to feed or extract gastric fluid, the first cover 203 can be used to isolate the first connector 201 from the outside world to prevent foreign objects from entering.

[0058] In addition, the present invention provides another embodiment of the second channel 102, in which the second channel 102 and the first channel 101 are connected by the elasticity of the material itself rather than by gravity.

[0059] like Figure 7 As shown, one end of the second channel 102 located inside the covering head 301 is an inwardly protruding state switching head 4, the end of the state switching head 4 is a blocking part 402, and the side wall of the state switching head 4 is provided with a third through hole 403.

[0060] When the traction rope 105 is in the tightened state, i.e. the first state, the blocking part 402 is close to the inside of the second channel 102, isolating the first channel 101 and the second channel 102. At this time, the milk enters the stomach through the first channel 101 and the first through hole 103, while the gas in the stomach enters through the second through hole 30 and is discharged through the second connector 202.

[0061] When the traction rope 105 is in the relaxed state, i.e. the second state, there is an air gap 401 between the blocking part 402 and the second channel 10. At this time, the air gap 401 and the third through hole 403 connect the first channel 101 and the second channel 102 to facilitate the extraction of gastric fluid.

[0062] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
