[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0034] Example 1
[0035] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-6 A gastric tube device with positioning function includes a gastric tube assembly 1, a control switch 2, a positioning transmitter 3, a check valve 4, a fixing device 6, and an insertion tube 7.
[0036] The gastric tube assembly 1 includes an outer tube 11, a connecting wire 12, and an inner tube 13. The connecting wire 12 and the inner tube 13 are fixedly installed inside the outer tube 11. The connecting wire 12 is located on one side of the inner tube 13. One end of the connecting wire 12 is electrically connected to a control switch 2, and the other end is electrically connected to a positioning transmitter 3. A fixing device 6 is connected to the outer end of the outer tube 11. The inner ends of the outer tube 11 and the inner tube 13 are open to the outside. The sound waves emitted by the positioning transmitter 3 are harmless to the human body.
[0037] The outer port of the inner tube 13 is connected to one end of the check valve 4, and the other end of the check valve 4 is provided with an inlet 5. The inner wall of the inner end of the outer tube 11 is fixedly connected to the positioning transmitter 3. The positioning transmitter 3 is located between the inner wall of the inner end of the outer tube 11 and the outer wall of the inner end of the inner tube 13. The outer wall of the outer end of the outer tube 11 is fixedly connected to the control switch 2. The outer side wall of the inner tube 13 is fixedly connected to and communicates with one end of the insertion tube 7. The other end of the insertion tube 7 is detachably connected to a sealing cap.
[0038] Preferably, both the outer tube 11 and the inner tube 13 are cylindrical pipes, and the diameter of the outer tube 11 is larger than the diameter of the inner tube 13.
[0039] Preferably, the inner tube 13 has a diameter of 15-18 mm, and the outer tube 13 has a diameter of 18-21 mm. More specifically, the inner tube 13 has a diameter of 15 mm, and the outer tube 13 has a diameter of 18 mm. The length of the inner tube 13 is greater than the length of the outer tube 11, and the outer end of the inner tube 13 extends outward through the nose pad 61.
[0040] Preferably, the outer wall of the outer tube 11 is provided with scale lines.
[0041] Among them, the check valve 4, the positioning transmitter 3, and the control switch 2 all adopt existing mature technologies. The check valve 4 can effectively prevent the backflow of gastric contents, cleaning fluid, and other liquids. This not only prevents gastric fluid from flowing back and contaminating the infusion system, ensuring the cleanliness of the infused fluids, but also avoids complications such as choking and infection caused by backflow, playing an important protective role in the patient's health.
[0042] Moreover, the presence of control switch 2 allows medical staff to easily control the working status of positioning transmitter 3, such as turning the positioning function on and off. At the same time, this design simplifies the operation process, reduces unnecessary operation steps, and improves the work efficiency of medical staff.
[0043] In use, the gastric tube assembly 1 is inserted into the stomach through the patient's nose, and the gastric tube is fixed to the patient's face by the fixing device 6. During the slow insertion of the gastric tube assembly 1 into the stomach, the positioning transmitter 3, connected to the connecting line 12 and the control switch 2, forms a circuit that can control the positioning transmitter 3 to emit sound waves. The source of the sound can be heard by placing a stethoscope on the body surface. Based on different anatomical positions, the position of the gastric tube end can be determined. Since the trachea and esophagus are far apart, it is possible to immediately determine whether the gastric tube end has entered the airway, preventing the patient from aspirating and suffocating, and improving the safety and reliability of the gastric tube.
[0044] In addition, medical staff can periodically open the sealing cap of the insertion tube 7, insert a cleaning brush into the inner tube 13, and then clean the inner tube 13 periodically with the cleaning brush to prevent food residue from clogging the tube. After cleaning the inner tube 13, a certain amount of physiological saline can be injected into the inner tube 13 through the check valve 4 to flush the inner tube 13.
[0045] Example 2
[0046] In some embodiments, please refer to the appendix to the instruction manual. Figures 3-6 The fixing device 6 includes a nose pad 61 and straps 62. Two straps 62 are provided and fixedly installed on both sides of the nose pad 61 respectively. The ends of the two straps 62 away from the nose pad 61 are detachably connected. The nose pad 61 is fixedly connected to the outer end of the outer tube 11.
[0047] Preferably, airbags 63 are fixedly installed inside the nose pad 61 and on both sides near the nose. Each airbag 63 is connected to an inflatable bladder via an inflation tube. The airbags 63 are adjustable in size according to the height of the nose bridge, making them suitable for different users.
[0048] Among them, the airbag 63 uses common medical-grade silicone rubber airbags or TPU airbags, which improves the durability of the airbag while ensuring softness. Even after multiple inflation and deflation operations, it is not easy to have problems such as rupture or aging.
[0049] The adjustable design of the airbag 63 reduces the pressure on the patient's nasal bridge caused by the nose pad 61, greatly improving the patient's comfort when wearing the gastric tube, avoiding problems such as nasal bridge pain and pressure sores caused by prolonged wear, improving patient compliance, and helping patients to better accept treatment.
[0050] Example 3
[0051] In some embodiments, please refer to the appendix to the instruction manual. Figures 3-4 The two straps 62 can be detachably connected at the ends away from the nose pad 61 by means of detachable buckles or Velcro.
[0052] The ends of the two straps 62 away from the nose pad 61 are connected by a detachable buckle. The detachable buckle includes a male buckle and a female buckle that cooperate with each other. One strap 62 is connected to the male buckle and the other strap 62 is connected to the female buckle. The male buckle has multiple teeth and the female buckle has a slot that can be adapted to the teeth. The male buckle and the female buckle are inserted into each other. The engagement position of the teeth and the slot can be adjusted according to the patient's head contour and wearing needs to achieve adjustment of the length of the straps 62.
[0053] The ends of the two straps 62 away from the nose pad 61 are detachably connected by Velcro. The nap and hook sides of the Velcro are respectively set at the corresponding ends of the two straps 62. The contact area of the nap and hook sides can be adjusted according to the actual wearing tightness requirements, thereby flexibly adjusting the connection tightness between the straps 62.
[0054] When in use, the strap 62 can be flexibly adjusted according to the size of the patient's head to ensure that the gastric tube is firmly fixed. At the same time, the air bladders 63 on both sides inside the nose pad 61 can be adjusted in size according to the height of the nose bridge of different people, which enhances the fit of wearing it. It is not only suitable for more patients, but also effectively prevents the gastric tube from shaking and shifting, further ensuring the stable function of the gastric tube.
[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
