Abstract

The invention relates to the technical field of medical appliances. The method for fixing the tracheal cannula of a tracheotomy patient, which is widely used in clinic, is implemented by knotting a cotton rope, cotton strip or gauze on a fixing hole/fixing holes on one or both ends of the tracheal cannula so as to fix the tracheal cannula to the neck. The invention aims to provide a tracheal cannula fixation appliance which can be quickly replaced and does not need knotting. The tracheal cannula fixation appliance is composed of a hollow tracheal cannula fixation rope (2) and two self-locking devices (3), wherein the insides of the walls on both ends of the tracheal cannula fixation rope (2) are provided with a lock catch (21). The application method of the tracheal cannula fixation appliance comprises the following steps: comparing the circumference of the tracheal cannula fixation appliance with the actual neck circumference; cutting off excess length of both ends of the tracheal cannula fixation rope; and after passing the self-locking device through the tracheal cannula fixing holes, closing the self-locking end, and inserting the self-locking end into the two ends of the tracheal cannula fixation rope so as to be locked by the internal lock catch. The invention lowers the probability of accidental tripping of the tracheal cannula and the risks of neck skin or wound surface injury and infection of the patient, relieves the patient of pain, and reduces the workload of the medical care personnel.

Description

Tracheal casing pipe is articles for use fixedly

Technical field

The present invention relates to technical field of medical instruments, especially a kind of tracheal casing pipe that is applicable to the fixed air pipe-in-pipe that tracheotomy patients is used is articles for use fixedly.

Background technology

At present, clinical in the method for widely used fixedly tracheotomy patients tracheal casing pipe be to use cotton cord, cotton bar or gauze, take at one end or the method for two ends tracheal casing pipe fixing hole knotting, tracheal casing pipe is fixed in cervical region.

This fixing means has obvious defects, mainly comprise: 1, the fixation procedure length that expends time in: each fixing two tweezers of needs use or vascular forceps are tied a knot in tracheal casing pipe fixing hole one or both ends, for clear and definite fixed effect, every end need be made a call to 3 to 4 fast knots, time more than at least 1 minute, the long operating time is to critical patient, especially restless tangible patient when urgent the rescue, be the significant adverse factor, increase the rescue difficulty and the mortality rate of critical patient; 2, complex operation, increase accident and take off the manage-style danger: owing to will repeatedly tie a knot, each knotting is certain for effect, need to use,, cause that very easily tracheal casing pipe is to the quick tractive of offside in case a hands is slipped out of the hand than great strength, even the tracheal casing pipe tractive removed the escape pipe cutting opening, cause unexpected tube drawing, and unexpected tube drawing is fatal to the tracheotomy patients of neck tissue swelling and laryngeal edema, the other types patient is also increased air flue damage, the hemorrhage and probability that infects; 3, increase the damage of cervical region wound surface: tradition uses cotton cord or cotton to be with fixed method, because static line is thin, big to cervical region wound surface pressure, static line is polluted by the oozing of blood sepage around the tracheal casing pipe easily and becomes stiff, the long-term friction and local chafe can be caused the skin injury of cervical region wound surface.The patient of especially original skin of neck damage, not only the cervical region wound surface is difficult to healing, and under the friction and pressure of static line, the cervical region wound surface is constantly deepened, for wound repair is brought difficulty; 4, increase cervical region traumatic infection probability: tradition uses cotton cord or cotton to be with fixed method, because the static line material is the cotton goods, can absorb the perspiration of skin of neck and the transudate of cervical region wound surface, make fixing band become the good culture medium of antibacterial, increase the chance that skin of neck and Pipe Cutting cutting opening infect, especially cervical region is existed patient's (as neck surface wound, craniocerebral trauma comatose patient) of wound surface, the long-term tracheotomy tracheal intubation of needs, the infection probability of cervical region wound surface and tracheotomy mouth is bigger; 5, the nursery work of static line is loaded down with trivial details: be the cervical region wound surface damage of avoiding tracheotomy patients and the infection of infection and tracheotomy mouth, need the medical worker to regularly replace the trachea fixing band, increase medical personnel's workload, frequent more scavenge trunk fixing band increases unexpected tube drawing risk again simultaneously, and the patient is caused more danger.

So far, still there are not the fixedly protection articles for use of usefulness of satisfied tracheal casing pipe clinically.

Summary of the invention

The object of the present invention is to provide fixedly articles for use of a kind of tracheotomy postoperative tracheal casing pipe, fixedly articles for use are easy to use, replacing is quick, safe and effective, can reduce the tracheal casing pipe accident and take off the probability of pipe, reduce damage of patient's skin of neck or wound surface and infection risk, alleviate patient suffering and medical personnel's workload.

The invention provides fixedly articles for use of a kind of tracheal casing pipe, tracheal casing pipe static line and two self-locking devices of being had snap close by hollow, tube wall inside, two ends constitute, and described snap close is conical, and snap close quantity is on every end tube wall more than 2; Snap close can with the tight locking of self-locking device, and self-locking device is connected with tracheal casing pipe fixing hole on the tracheal casing pipe.

The present invention in use, by comparing with actual neck circumference, wipe out the unnecessary length at tracheal casing pipe static line two ends, after passing through the tracheal casing pipe fixing hole with two self-locking devices respectively, the self-locking end is locking voluntarily, the self-locking end of locking is inserted tracheal casing pipe static line two ends again, blocks with the snap close of its tube wall inside, final tracheal casing pipe static line, two identical self-locking devices and tracheal casing pipe form closed circuit, are fixed in patient's cervical region.Reach the purpose of rapid, reliable fixed air pipe-in-pipe.

Described self-locking device is made of the self-locking end at intermediary connecting portion and two ends, two self-locking ends will pin each other by the inboard trapezoidal self-locking tooth of its inboard self-locking end and be fixed into conical series connection integral body more than one, closely block with these many conical series connection how conical snap close whole and inside, tracheal casing pipe static line two ends again.

The inboard trapezoidal self-locking number of teeth amount of self-locking end outside half cone-shaped latch and self-locking end is suitable.

The how conical snap close quantity of inside, tracheal casing pipe static line two ends can be on every end tube wall more than 3.

The inboard trapezoidal self-locking number of teeth amount of self-locking end outside half cone-shaped latch and self-locking end is more than 2.

Material of the present invention can be medical grade polrvinyl chloride (PVC) or Merlon (PC), to guarantee the difficult combustion of this suit, acid and alkali-resistance, antimicrobial, wear-resisting and have warmth retention property and suitable elasticity preferably.

The present invention is used for fixing tracheal casing pipe at the tracheotomy postoperative, easy to use, replacing rapidly, does not need knotting, can reduce the tracheal casing pipe accident and take off the probability of pipe, reduce damage of patient's skin of neck or wound surface and infection risk, alleviate patient suffering and medical personnel's workload.
