Specific embodiments
[0031] The following describes clearly and completely the technical solutions in the embodiments of the present utility model through specific specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific embodiments. Without conflict, the following embodiments and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model.
[0032] Figure 1 -6 shows the main technical content of this embodiment. This specific embodiment provides a double-lumen gastric tube, which includes:
[0033] A tube body 1, the tube body 1 having a first end 11 and a second end 12, wherein the first end 11 has a gastric tube hole 13;
[0034] A guide wire channel 2 disposed within the tube body 1, wherein the guide wire channel 2 has a first end 22 and a second end, wherein the first end 22 is located within the first end 11, and the second end penetrates out of the tube body 1;
[0035] A guide wire 3 disposed within the guide wire channel 2, wherein the guide wire 3 is configured to be separable within the guide wire channel 2.
[0036] During use, the guide wire 3 is inserted into the guide wire lumen 2 to increase the hardness of the tube body 1, and then it is pushed into the patient's body starting from the first end 11 of the tube body 1. At this time, under the action of the guide wire 3, the tube body 1 generates a certain hardness, so that the gastric tube will not be folded and coiled due to resistance during the pushing process; after the first end 11 reaches the target position, the guide wire 3 is withdrawn from the guide wire lumen 2 to complete the indwelling of the gastric tube.
[0037] Reference Figure 2 —3. In this embodiment, flushing holes 21 are formed in the outer wall of the guide wire lumen 2. Among them, the distance between the flushing hole 21 and the first end 22 is less than the distance between the flushing hole 21 and the second end. More specifically, a plurality of the flushing holes 21 are provided, and among them, the plurality of flushing holes 21 are arranged on the outer wall of the guide wire lumen 2; more preferably, each of the flushing holes 21 is arranged in the direction from the first end 22 to the second end. After the tube body 1 is inserted into the patient's body and the guide wire 3 is withdrawn from the guide wire lumen 2, flushing fluid can be injected through the guide wire lumen 2, and the flushing fluid flows out through the gastric tube hole 13 to perform gastrointestinal flushing for the patient.
[0038] More preferably, the first end 22 of the guide wire lumen 2 is configured not to allow the guide wire 3 to penetrate through. Specifically, the first end 22 has a closed structure. After the guide wire 3 is inserted into the guide wire lumen 2, the guide wire 3 will not protrude from the guide wire lumen 2, thereby preventing the guide wire 3 from protruding outside the tube body 1 and avoiding the guide wire 3 from stabbing the tissue mucosa in the patient's body.
[0039] Reference Figure 3 and Figure 6 , in this embodiment, the tube body 1 has a center line, and the diameter of the first end 11 gradually decreases in the direction along the center line of the tube body 1 and away from the second end 12. Specifically, the first end 11 has a spherical end, and the diameter of the spherical end is smaller than the diameter of the tube body 1, so that the first end 11 as a whole presents a bullet head shape.
[0040] Reference Figure 2 —3. In this embodiment, the guide wire lumen 2 is arranged along the inner wall of the tube body 1. Specifically, the guide wire lumen 2 and the tube body 1 are integrally connected. With this arrangement, the space inside the tube body 1 can be reserved as much as possible, and the tube body 1 can be prevented from being blocked to a certain extent.
[0041] Alternatively (not shown), the guide wire lumen 2 is formed in the tube wall of the tube body 1. In this setting, the flushing holes 21 are arranged on the inner wall of the tube body 1 and communicate with the guide wire lumen 2. During use, the guide wire 3 is inserted into the guide wire lumen 2 to support the tube body 1, facilitating the insertion of the tube body 1 into the patient's body. Then, after the guide wire 3 is withdrawn from the guide wire channel, flushing fluid can be injected through the guide wire channel to perform gastrointestinal flushing for the patient.
[0042] Reference Figure 5 —7, in this embodiment, the second end includes: a flushing connector 4 and a sealing member. The flushing connector 4 communicates with the guide wire lumen 2. The flushing connector 4 has an open state and a closed state. Among them, the sealing member is configured to be able to switch the flushing connector 4 between the open state and the closed state. During use, the flushing connector 4 is switched to the open state through the sealing member. At this time, the guide wire 3 can be inserted into the guide wire lumen 2. After the tube body 1 is inserted, the guide wire 3 is withdrawn from the guide wire lumen 2, and then the flushing connector 4 is switched to the closed state through the sealing member. Similarly, when performing a flushing operation on the patient, the flushing connector 4 can be switched to the open state, and after flushing is completed, the flushing connector 4 is switched to the closed state through the sealing member.
[0043] More specifically, the sealing member includes: a connecting portion 42 and a sealing portion 43. Among them, the connecting portion 42 is rotatably connected to the flushing connector 4. The sealing portion 43 is integrally connected to the connecting portion 42, and the sealing portion 43 can partially enter the flushing connector 4 to switch the flushing connector 4 from the open state to the closed state.
[0044] More specifically, the connecting portion 42 can be made of a flexible material. Among them, the sealing portion 43 is made of the same material as the connecting portion 42. Preferably, the connecting portion 42 and the sealing portion 43 can be made of one of silicone and rubber.
[0045] In this embodiment, the second end portion 12 of the tube body 1 also has a connector 121. Through this interface, nutrients and medications can be delivered to the patient.
[0046] The usage method of the present utility model:
[0047] 1. Insert the guide wire into the guide wire lumen so that the guide wire supports the tube body, and then insert the tube body with the guide wire into the patient's body;
[0048] 2. After inserting the tube body into the patient's body, withdraw the guide wire from the guide wire lumen, and then use the sealing portion to seal the flushing connector;
[0049] 3. When performing gastrointestinal irrigation for a patient, remove the sealing member from the irrigation connector, externally connect the irrigation fluid through the irrigation connector, and then inject the irrigation fluid into the guide wire lumen to perform gastrointestinal irrigation for the patient.
[0050] The description of the above embodiments is only for understanding the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements can still be made to the present utility model, and these improvements will also fall within the protection scope of the claims of the present utility model.
