Reverse-expansion nasal catheter fixing device with protective function

Abstract

The invention relates to the technical field of medical instruments, in particular to a reverse-expansion nasal catheter fixing device with a protective function, comprising a catheter mechanism, a catheter clamp mechanism and a sling mechanism; the catheter mechanism includes a first nasal catheter and a second nasal catheter, one end of the first nasal catheter is connected with a first connector, the other end of the first nasal catheter is connected with at least two first reverse expansion plugs sleeved with first intranasal catheters for insertion in the nasal cavity, one end of the second nasal catheter is connected with a second connector, and the other end of the second nasal catheter is connected with at least two second reverse expansion plugs sleeved with second intranasal catheters for insertion in the nasal cavity. The reverse expansion plugs are used to expand the nasal cavity so as to fix the intranasal catheters; in addition, the reverse expansion plugs can peristaltically deform with vibration of the nasal cavity, and damage to the inner wall of the nasal cavity is decreased to maximum extent.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a reverse expansion nasal catheter fixing device with protection function. Background technique [0002] In the medical process, it is often necessary to insert a gastric tube or an oxygen tube into the patient's nasal cavity, and most of these tubes are just a smooth hose with no fixing device on the tube, so it is easy to slip out, slide in, or even appear Restless patients constantly pull out the inserted catheter from the stomach or nasal cavity, which not only increases the workload and pressure of the medical staff and the patient's family members, but more importantly increases the pain of the patient's repeated intubation; For technical problems, most medical staff use adhesive tape to fix the tube wall at the outer end of the nose of the catheter, and if possible, use a nasal catheter fixing system for fixing.

[0002] In the medical process, it is often necessary to insert a gastric tube or an oxygen tube into the patient's nasal cavity, and most of these tubes are just a smooth hose with no fixing device on the tube, so it is easy to slip out, slide in, or even appear Restless patients constantly pull out the inserted catheter from the stomach or nasal cavity, which not only increases the workload and pressure of the medical staff and the patient's family members, but more importantly increases the pain of the patient's repeated intubation; For technical problems, most medical staff use adhesive tape on the outer end of the catheter to fix it, and if conditions permit, they will use a nasal catheter fixing system to fix it

[0003] The existing nasal catheter fixation only fixes the catheter outside the nose, but cannot effectively fix the catheter inside the body, resulting in the need to pay attention to the displacement of the catheter inserted into the nasal cavity at all times during the treatment process.
