Description

Technical Field

[0001] The utility model relates to the technical field of gastric tubes, in particular to a gastric tube for gastroenterology. Background Art

[0002] At present, the nasogastric tube commonly used in clinical gastroenterology is a silicone rubber tube of about 1 meter, mostly single-lumen tubes. For patients who need nasogastric feeding and oxygen inhalation, the gastric tube and oxygen tube need to be inserted into the two nostrils of the patient respectively, which is not very comfortable. The gastric tube is easily inserted wrongly during use. In order to test the position of the tail of the gastric tube, it is usually necessary to extract gastric juice from the gastric tube after the gastric tube is inserted. Some patients have less gastric juice, and the extraction process may cause irritation to the patient. Utility Model Content

[0003] In view of this, in order to solve the problems existing in the technical background, the utility model proposes a gastric tube for gastroenterology, and the specific technical solution is as follows:

[0004] A gastric tube for gastroenterology, comprising a gastric tube body, wherein the gastric tube body is provided with mutually independent breathing passages, wherein the breathing passages extend upward to a tracheal tube opening, wherein the tracheal tube opening and the gastric tube body are in a "Y" shape as a whole;

[0005] A plurality of through holes are opened at the lower end of the gastric tube body, and food or water flows out from the through holes. A PH detection head is arranged inside the gastric tube body, and the bottom end of the PH detection head contacts the bottom end of the gastric tube body. A guide wire is connected above the PH detection head, and the guide wire passes through the gastric tube body.

[0006] Furthermore, the diameter of the pH detection head is larger than the diameter of the through hole to prevent the pH detection head from extending from the through hole.

[0007] Furthermore, the respiratory passage has pores corresponding to the respiratory tract of the human body.

[0008] Furthermore, the diameter of the breathing passage is approximately one third of the diameter of the gastric tube body.

[0009] Furthermore, the bottom end of the gastric tube body is arc-shaped.

[0010] Furthermore, a second sealing plug and a first sealing plug are respectively provided on the upper side of the stomach tube body and at the tracheal tube opening to prevent dust from entering.

[0011] Furthermore, the outer wall of the gastric tube body is provided with scale lines along its length direction.

[0012] Furthermore, the detection head is a pH test paper.

[0013] The above technical solution has the following beneficial effects:

[0014] The gastric tube body of the utility model is provided with a breathing channel, which is independent of the food channel inside the gastric tube, and oxygen is supplied to the patient during nasogastric feeding, and there is no need to insert the trachea and the gastric tube through two nostrils respectively. When the gastric tube body is inserted, a PH detection head is provided inside the gastric tube body, and the gastric juice in the stomach is retained in the PH detection head through the through hole. The guide wire is taken out from the gastric tube body, and the PH detection head is observed to determine whether the gastric tube is in the stomach. There is no need to extract gastric juice separately, which improves the comfort of the patient and also improves the work efficiency of medical staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1: See Figure 1-2 A gastric tube for gastroenterology shown in the figure comprises a gastric tube body 1, wherein the gastric tube body 1 is provided with mutually independent breathing passages 9, wherein the breathing passages extend upward to a tracheal tube opening 5, wherein the tracheal tube opening and the gastric tube body 1 are in a "Y" shape as a whole;

[0020] A plurality of through holes 3 are provided at the lower end of the gastric tube body 1, and food or water flows out from the through holes 3. A PH detection head 8 is provided inside the gastric tube body 1, and the bottom end of the PH detection head 8 contacts the bottom end of the gastric tube body 1. A guide wire 2 is connected above the PH detection head 8, and the guide wire 2 passes through the gastric tube body 1.

[0021] The diameter of the PH detection head 8 is larger than the diameter of the through hole 3 to prevent the PH detection head 8 from passing through the through hole 3. The respiratory channel 9 is provided with an air hole 4 corresponding to the respiratory tract of the human body. The diameter of the respiratory channel 9 is approximately one-third of the diameter of the gastric tube body 1. The bottom end of the gastric tube body 1 is arc-shaped. A second sealing plug 7 and a first sealing plug 6 are respectively provided on the top of the gastric tube body 1 and at the tracheal tube opening 5 to prevent dust from entering. The outer wall of the gastric tube body 1 is provided with scale lines along its length direction, and the detection head is a PH test paper.

[0022] When the utility model is used, the stomach tube body 1 is inserted from the nasal cavity. The extension length of the stomach tube body 1 can refer to the scale line. After it enters the stomach, the PH detection head 8 inside the stomach tube body 1 can absorb gastric juice. The PH detection head 8 is taken out from the stomach tube body 1 together with the connected guide wire 2. By observing the PH detection head 8, it is determined whether the end of the stomach tube body 1 is in the stomach. The respiratory passage 9 corresponds to the respiratory tract of the human body and has a pore 4. The gas flows out to the respiratory tract from the pore 4. During transportation, the first sealing plug 6 and the second sealing plug 7 plug the tracheal tube opening 5 and the tube opening of the stomach tube body 1 to prevent dust from entering. When in use, the first sealing plug 6 and the second sealing plug 7 are opened.

[0023] The stomach tube body 1 of the utility model is provided with a breathing channel 9, which is independent of the food channel inside the stomach tube, and oxygen is supplied to the patient during nasogastric feeding, and there is no need to insert the trachea and the stomach tube through two nostrils respectively. When the stomach tube body 1 is inserted, a PH detection head 8 is provided inside the stomach tube body 1, and the gastric juice in the stomach flows through the through hole 3 to the PH detection head 8. The guide wire 2 is taken out from the stomach tube body 1, and the PH detection head 8 is observed to determine whether the stomach tube is in the stomach. There is no need to extract gastric juice separately, which improves the comfort of the patient.

[0024] The basic principles and main features of the utility model are described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
