Description

TECHNICAL FIELD

The present disclosure relates to the field of medical devices, and in particular to a fixing device for double-tube intubation.

BACKGROUND

A nasal feeding nutrition catheter (also known as a nasointestinal tube) made of a high polymer material is a medical device, which is intubated from a nasal cavity, reaches the duodenum or jejunum through the pharyngeal, esophagus and stomach, is used for enteral nutrition infusion, and plays an important role in nutritional support for patients. Using the nasointestinal tube to infusing the nutrient solution from the nasal cavity has become a widely used clinical nursing and operation technique, and is a necessary and important medical technical means to ensure that comatose patients, vegetative patients or patients not eating orally due to digestive tract diseases such as the esophagus cancer, esophageal stenosis, laryngocarcinoma and hypopharyngeal carcinoma can intake enough nutrition during their treatment to maintain the physical health.

According to “T/CNAS20-2021 Intubation and Maintenance of Nasointestinal Tube in Adult Patients” and the nursing technical practice code “Nursing Practice Guideline for Enteral Nutrition in Patients with Stroke” (2021), the clinically used nasointestinal tube is fixed by adopting a platform aloft method. The platform aloft method is that the pipeline intubated from the nasal cavity is directly affixed to both sides of the patient's alar and the cheek for pipeline fixation after being intersected by a medical tape, to ensure that the nasointestinal tube intubated into the nasal cavity is accurately positioned in vivo and can work normally. The quality of the adhesive substance affixed to the tape as well as the tissue structure and thread count of a fabric are important parameters for controlling the quality of a tape product, and directly affect the using effect of the platform aloft method of the nasointestinal tube; and the cleanliness of the head and face skin of the patient and the operation skill of an operator are also important factors affecting the fixation and positioning of the nasointestinal tube. Since the pipeline is directly affixed to the skin surface of the patient by adopting the tape, the patient's skin allergy, sweat influence, posture movement and weak tape adhesion will all cause that the tape cannot be cling to the skin, is easy to upwarp and loosen, thus occurring a shift for the pipeline fixation, causing infection and injury, affecting the treatment effect, even leading to the pipeline slip to become the serious adverse event with the medical risk.

The fixation for the nasointestinal tube is the concerned key and difficult points in the nursing technical operation training and the enteral nutrition treatment. To avoid the occurrence of the adverse event such as the patient's skin allergy and infection, clinical nursing has strict regulations on nasointestinal tube in indwelling, extubation, complication prevention and treatment, requiring: the adhesive tape and the fixing position thereof are replaced every 24-48 h, and the catheter must be adjusted or replaced in time for a damp, a looseness or a shift. These frequent daily operations increase the nursing labor intensity, aggravate the workload of the nursing management, and even affect the treatment experience of the patient.

The traditional method for fixing the nasointestinal tube by adopting the platform aloft method needs to cut the tape, with repeated pasting, complex operation and time consuming, the fixing effect replies on the hand feeling and experience of the operator, the fixing tape on the cheek needs to be torn down when the nasointestinal tube is replaced regularly, the patient has a strong pain, thus affecting the treatment experience, and using the tape to fix the nasointestinal tube for a long time will also lead to skin allergy. In view of the quality difference of the tape products from different manufacturers, due to the influence of the patient's face, especially alar secretion, long-time tape adhesion, operation experiences of clinical staff and other reasons, the common issues for fixing the nasointestinal tube clinically include: time consuming for fixation, complex operation, pipeline shift, pipeline slip, blockage by foreign matters, poor circulation, end cracking, extraction difficulty and the like, in particular, the pipeline shift and slip are the most common, which may cause secondary harm to the patient, occur the non-medical extubation, seriously affect the effectiveness of treatment, and has become the main factors for poor events such as the medical safety hazard and the occurrence of an infection. During regular nasal feeding operation, the tail end of the nasointestinal tube needs to be lifted for infusion, the tape affixed to the cheek needs to be torn and affixed repeatedly, which easily causes the skin discomfort or injury of the patient, and the above-mentioned clinical pain points have become the issues that confuse clinical for a long time and are not solved well.

The patent No. CN211536105U discloses a fixator intubated through a nasal tracheal tube, a nasal intubation tube is arranged on a cushion to clamp and fix the tracheal tube, both sides of the cushion are connected with elastic bands with ear bands, and the fixator is hung to the patient's ears through the ear bands, thus achieving the fixation for the fixator. Due to the elastic action of the elastic bands, the ear bands generate a relatively great extrusion force to the patient's ears, and long-term wearing will cause damage to the ears.

The patent No. CN205964508U discloses a spectacle frame type fixing device for a nasal feeding tube, a pipeline passes through a fixing tube mounted on the spectacle frame, and the pipeline is prevented from moving axially along the fixing tube by tightening screws mounted on side walls of the fixing tube, thus fixing and positioning.
