Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of stomach tube, concretely relates to a stomach tube of preventing falling off. BACKGROUND

[0002] The stomach tube is a kind of medical instrument commonly used in clinic, is mainly used for the drainage, perfusion and suction of patient's stomach fluid, and is widely applied in the treatment process of emergency, operation and long-term hospitalized patient.The existing stomach tube is usually directly inserted into the stomach of patient by a catheter, and is fixed by external fixing device such as patch or bandage.However, the fixing mode of this kind of traditional stomach tube has certain shortcomings.

[0003] Firstly, the fixing device of existing stomach tube mostly adopts simple pasting form, is easily influenced by external environment, such as patient movement or accidentally pulling, leads to stomach tube falling off or displacement, not only influences the effect of medical operation, but also can bring pain or injury to patient.Secondly, in the process of insertion and extraction, catheter is easily rubbed with the nasal cavity or esophageal wall of patient, increases the discomfort of patient, especially when needing to be frequently replaced or cleaned, this situation is particularly obvious, and the cleaning mode of traditional stomach tube by physiological saline injection is not thorough enough.In addition, the flow channel of current stomach tube is usually in open state when not being used, and bacteria or other pollutants in external air are easily entered into the body of patient, increases the risk of infection, and the problem of gastric reflux is also relatively common, influences the comfort and safety of patient. SUMMARY

[0004] In view of the problems in prior art, the utility model aims at providing a stomach tube of preventing falling off, which can effectively solve the problems of traditional stomach tube, such as poor fixing, inconvenient cleaning and insufficient flow channel control, and improve the use comfort and medical safety of patient.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A stomach tube of preventing falling off, including support nose frame, outer hose and arc plate, the support nose frame is the V-shaped structure of downward open mouth, the support nose frame both sides are outwardly provided with extension plate, the support nose frame is placed at the nose end of patient, the inner side of extension plate is pasted on the face of patient, the front side of support nose frame is inwardly provided with mounting lug, the surface of mounting lug is provided with through hole, the through hole corresponds with one nostril of patient, the outer hose passes through through hole, the inner hose is passed through in the inner portion of outer hose, the surface of outer hose is provided with notched groove, the notched groove corresponds with through hole, the locking screw bolt is screwed on the outer side of mounting lug, the locking screw bolt is perpendicular to the axis of through hole, the end portion of locking screw bolt is placed in the inner side of notched groove, and the locking screw bolt is extruded and fixed to the inner side of inner hose.

[0007] Further, one end of the inner hose is provided with an arc head, and the other end of the inner hose is provided with a feeding pipe, and the arc head is placed in the stomach of the patient.

[0008] Further, the side surface of one end of the inner hose close to the arc head is uniformly provided with a discharging groove.

[0009] Further, the arc-shaped plate is attached to the neck of the patient, the outer hose penetrates through the arc-shaped plate, the arc-shaped plate is symmetrically connected with neck connecting bands on both sides, the magic tapes are arranged on the end surfaces of the two neck connecting bands away from the arc-shaped plate, and the two magic tapes are matched with each other.

[0010] Further, the inner wall of the support nose frame is uniformly provided with anti-skid rubber convex strips.

[0011] Further, the surface of the extension plate is connected with an elastic band, and the end of the elastic band away from the extension plate is provided with an elastic earring.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] Firstly, the utility model can realize the stable fixation of the gastric tube through the combination of the support nose frame and the outer hose and the cooperation of the locking screw, and the extrusion fixation between the locking screw and the inner hose avoids the problem of gastric tube falling caused by external tension or patient activity, thereby improving the safety and stability of the gastric tube in the use process. This design solves the problem of the traditional gastric tube fixation not being firm in the background art, can effectively prevent the gastric tube from falling in the patient activity or treatment process, and ensures that the gastric tube always maintains the correct position in the whole treatment process.

[0014] Secondly, the combination pipe design of the inner hose and the outer hose, especially the arc head of the inner hose, can smoothly guide the gastric tube to be inserted into the stomach of the patient, and avoids the patient's discomfort caused by the improper insertion angle of the traditional gastric tube. This innovation makes the gastric tube insertion process smoother, reduces the pain or discomfort of the patient caused by the intubation operation. In addition, when the gastric tube needs to be cleaned, the inner hose is pulled out in the pediatric department, and after cleaning, it is reinserted. In this process, since the inner hose moves inside the outer hose, it will not directly contact the patient, thereby not causing discomfort to the patient. After the inner hose is taken out, it can be thoroughly cleaned. The discharging groove designed on the surface of the inner hose ensures smooth liquid discharge, prevents gastric juice reflux or leakage caused by blockage, and further improves the comfort and effectiveness of the gastric tube in the use process.

[0015] Furthermore, this invention ensures stable fixation of the gastric tube at the patient's neck through the design of the arc-shaped plate and the neck connecting strap. The flexible design of the arc-shaped plate allows it to fit snugly against the patient's neck, preventing the gastric tube from loosening or falling off due to head movement. The Velcro fastener on the neck connecting strap makes the fixation process simpler and faster, and is adjustable to accommodate patients of different body types. This solves the problem of easy detachment or difficulty in adjustment of fixation devices in the prior art, further improving patient comfort and the stability of the gastric tube.

[0016] Furthermore, the evenly distributed anti-slip rubber protrusions on the inner wall of the nasal support effectively increase friction with the patient's face, preventing displacement of the gastric tube due to facial movements or head rotation. This anti-slip design overcomes the shortcomings of traditional gastric tube fixation, improving the overall reliability of the device, ensuring the stability of the gastric tube during the patient's daily activities, and reducing unnecessary risks caused by tube displacement or loosening.

[0017] Finally, the combination of the extension plate and the elastic band, especially the design of the elastic ear loop, allows the gastric tube to be securely fixed to the patient's ear, distributing pressure and reducing the burden on the patient's ear. This design effectively solves the discomfort and pressure problems that may occur in traditional fixation methods, further improving patient comfort and ensuring that the gastric tube will not cause discomfort or damage during long-term wear.
