Description

Technical Field

[0001] The utility model relates to the field of gastric tubes, in particular to an automatically dredged and anti-blocking gastric tube. Background Art

[0002] A gastric tube can be inserted into the stomach through the mouth or nostrils to actively deliver medicine, water and food to the patient. It is mostly used for patients who cannot swallow independently.

[0003] During the insertion of the gastric tube, in order to avoid damaging the esophagus and stomach, the bottom of the gastric tube is often closed and chamfered, and the side opening is used for discharge. Since food and incompletely crushed medicines contain some small particles, they are easily stuck at the discharge port during the process of being fed into the stomach, accumulating and forming a blockage problem. The gastric tube often needs to be pulled out for replacement, which not only increases the cost and the patient's pain, but also causes the loss of some drugs, making it impossible for patients to get accurate medication.

[0004] The utility model with application number 202223436320.0 discloses a new type of gastric tube, including a filtering component and a double-pass component. The filtering component can filter larger particles of food and drug residues, but it is inconvenient to maintain and cannot avoid the loss of drug residues, and needs to be improved. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide an automatically dredged and anti-blocking stomach tube, which can automatically dredge after the pressure increases to avoid the blockage problem.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an automatically unblocked anti-blocking gastric tube, including: a flexible gastric tube, a first pipe joint and a flexible guide head, the first pipe joint is arranged at the top end of the flexible gastric tube, the flexible guide head is arranged at the bottom end of the flexible gastric tube, a discharge port is arranged on one side of the bottom end of the outer circle of the flexible gastric tube, and the flexible guide head is provided with a plurality of slots extending radially from the middle to the outer circle so that the flexible guide head is divided into a plurality of flexible cantilevers in annular arrays.

[0007] In a preferred embodiment of the present invention, a second pipe joint is provided on one side of the first pipe joint.

[0008] In a preferred embodiment of the present invention, the inner diameter of the second pipe joint is smaller than the inner diameter of the first pipe joint.

[0009] In a preferred embodiment of the present invention, the discharge port adopts a round hole or a waist hole structure.

[0010] In a preferred embodiment of the present invention, the flexible stomach tube and the flexible guide head adopt an integrated structure.

[0011] In a preferred embodiment of the present invention, a conical hole is concavely arranged at the top of the guide head, and a micro hole extending to the bottom of the guide head is arranged at the bottom of the conical hole.

[0012] In a preferred embodiment of the present invention, a guide wire positioning blind hole is concavely arranged on the side wall of the tapered hole.

[0013] In a preferred embodiment of the present invention, the diameter of the micropores is no greater than 1 mm.

[0014] In a preferred embodiment of the utility model, a circle of tapered surface extending downward is arranged on the outer circle of the flexible guide head, and an arc surface connected to the tapered surface is arranged at the bottom of the flexible guide head.

[0015] The beneficial effects of the utility model are as follows: the utility model points out an automatically unblocked anti-blocking gastric tube, which delivers medicine, water or food into the patient's stomach through a flexible gastric tube through a pressurized syringe. When particulate matter accumulates at the bottom of the flexible gastric tube and blocks the discharge port, the pressurized syringe can be used to increase the pushing pressure, and the particulate matter pushes the flexible guide head downward under pressure. After the force on the flexible cantilever increases, it flips outward. After the flexible guide head is opened, the particulate matter can be diverted downward through the flexible guide head, thereby realizing automatic unblocking of the blockage and reducing the pressure in the flexible gastric tube. The flexible cantilever elastically resets, and the medicine, water or food continues to enter the patient's stomach through the discharge port, thereby avoiding blockage problems and drug loss, and ensuring the accuracy of medication.

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1~Figure 3 , the utility model embodiment includes:

[0022] like Figure 1 The automatically unblocking anti-blocking gastric tube shown comprises: a flexible gastric tube 1, a first pipe joint 2 and a flexible guide head 5. The first pipe joint 2 is arranged at the top of the flexible gastric tube 1. In this embodiment, a second pipe joint 3 is arranged on one side of the first pipe joint 2. The inner diameter of the second pipe joint 3 is smaller than the inner diameter of the first pipe joint 2. The inner diameter of the first pipe joint 2 is large, and particulate-containing medicines and pasty foods can be pushed in through a syringe to increase dietary fiber and nutrient supply. The inner diameter of the second pipe joint 3 is small, and water-like liquid food or medicine can be pushed in through a syringe, which is easy to use.

[0023] The flexible guide head 5 is arranged at the bottom end of the flexible stomach tube 1. The flexible stomach tube 1 and the flexible guide head 5 adopt an integrated structure, or a split structure for thermal connection. The flexible stomach tube 1 and the flexible guide head 5 can be made of silicone or flexible polyurethane material, which can be replaced regularly and has high safety.

[0024] like Figure 2 As shown, a circle of tapered surface 9 extending downward is arranged on the outer circle of the flexible guide head 5, and an arc surface 10 connected with the tapered surface 9 is arranged at the bottom of the flexible guide head 5, forming a guiding structure, which is conducive to guiding the flexible gastric tube 1 to be inserted into the patient's stomach through the mouth or through the nostrils, avoiding damage to the patient's esophagus and stomach during the insertion process.

[0025] A discharge port 4 is provided at one side of the outer bottom end of the flexible gastric tube 1, so that the medicine, water or food in the flexible gastric tube 1 can enter the patient's stomach through the discharge port 4. In this embodiment, the discharge port 4 adopts a circular hole or a waist hole structure, which is flexible to choose.

[0026] like Figure 2 and Figure 3 As shown, a plurality of slots extending radially from the middle to the outer circle are provided in the flexible guide head 5 so as to divide the flexible guide head 5 into a plurality of flexible cantilevers 8 in annular arrays. The flexible cantilever 8 has a certain elasticity and elastically maintains a closed state.

[0027] During use, when particles accumulate at the bottom of the flexible gastric tube 1 and block the discharge port 4, the pushing pressure can be increased by a pressurized syringe. The particles are pressed and push the flexible guide head 5 downward. After the force on the flexible cantilever 8 increases, it flips outward. After the flexible guide head 5 is opened, the particles can be diverted downward through the flexible guide head 5, thereby automatically clearing the blockage and reducing the pressure in the flexible gastric tube, so that the flexible cantilever 8 can be elastically reset.

[0028] like Figure 2 As shown, a conical hole 11 is concavely arranged at the top of the guide head 5, and a microhole 6 extending to the bottom of the guide head 5 is arranged at the bottom of the conical hole 11. In this embodiment, the diameter of the microhole 6 is not greater than 1 mm, and the microhole 6 can discharge the liquid food or medicine in the conical hole 11 downward, reduce the problem of liquid food and medicine residue in the flexible gastric tube 1, and improve the accuracy of medication.

[0029] The design of the tapered hole 11 is conducive to the outward turning of the flexible cantilever 8 after the force increases. In addition, a guide wire positioning blind hole 7 is concavely arranged on the side wall of the tapered hole 11. During the process of inserting the flexible gastric tube 1 into the stomach, the stainless steel guide wire can be first inserted into the flexible gastric tube 1, and the guide wire positioning blind hole 7 is used to position the end of the stainless steel guide wire. The stainless steel guide wire increases the toughness of the flexible gastric tube 1, so that the flexible gastric tube 1 can be inserted into the stomach more smoothly.

[0030] In summary, the utility model discloses an automatically unblockable anti-blocking gastric tube, which can automatically unblock and avoid the problem of the discharge port being blocked by particulate matter, thereby improving the convenience of use and the accuracy of medication, and helping to reduce the frequency and cost of gastric tube replacement.

[0031] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
