Description

Adjustable nasal balloon hemostat

technical field

The utility model belongs to a nasal cavity airbag hemostat, in particular to an adjustable nasal cavity airbag hemostat.

Background technique

In otorhinolaryngology head and neck surgery, the treatment methods for patients with epistaxis often use hemostatic cotton packing method and posterior nasal cavity urinary catheter packing method in clinical practice. Both methods have certain problems:

(1) When using hemostatic materials such as Vaseline oil gauze and expanding sponge for packing, blind packing or excessive packing is prone to occur. At the same time, hemostatic materials such as expanding sponge are more likely to adhere to blood clots, and the adhesion to surrounding tissues is serious, which is easy to cause when removing. Bleeding again.

(2) When the urinary catheter is used for nasal packing, it is easy to cause discomfort such as headache and nasal distention of the patient. Due to the limitation of the fixation method, it is easy to cause excessive pressure on the patient's nasal alar to cause damage and increase the patient's pain; in addition, due to the traditional urinary catheter The lumen is too long, and there are too many lumen left outside the nasal cavity during fixation. It needs to be fixed with a knot and gauze, which affects the appearance and affects the daily eating.

SUMMARY OF THE INVENTION

The technical problem to be solved by the utility model is to provide an adjustable nasal airbag hemostatic device with light structure, convenient operation, rapid hemostasis and improved comfort.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

An adjustable nasal airbag hemostatic device, including a urinary catheter and its airbag, the airbag located at the head end of the urinary catheter is connected to a water injection port through a pipeline, the tail end of the urinary catheter is covered with a fixer, and the urinary catheter on the inner side of the fixer is covered with hemostatic cotton; The device is a silicone hollow collar; the hemostatic cotton is wrapped with mesh.

The urinary catheter is a natural silicone rubber hollow tube.

Small holes are scattered on the catheter where the hemostatic cotton covers.

The hemostatic cotton is chitosan hemostatic cotton.

The hemostatic cotton is wavy.

In view of the problems in the current treatment methods for epistaxis, the adhesion of the hemostatic cotton to the surrounding tissues caused by the packing of the urinary catheter and the hemostatic cotton, the breakage of the patient's nasal alar skin caused by the folded and fixed end of the urinary catheter, and the complicated operation, the inventors have carried out a method for the existing universal urinary catheter. Improved, designed and produced an adjustable nasal balloon hemostatic device, including a urinary catheter and its balloon. The balloon at the head end of the urinary catheter is connected to the water injection port through a pipeline. The tube is covered with hemostatic cotton; the fixer is a silicone hollow collar; the hemostatic cotton is wrapped with mesh. in,

(1) Due to the use of clinical universal urinary catheters, the length of the product can be adjusted and determined according to the age of the patient and the structure of the nasal cavity, so as to be suitable for different groups such as adults and children, and improve the comfort of the patient.

(2) Retain the original bladder of the urinary catheter, which plays the role of hemostasis and secondary fixation.

(3) Improve the structure, shape and material of the hemostatic cotton. The outer wall of the hemostatic cotton is wrapped with a layer of mesh, which can not only fix the hemostatic cotton and the urinary catheter to prevent the hemostatic cotton from protruding, but also avoid the adhesion of the hemostatic cotton to the surrounding tissue.

(4) A silicone hollow collar is added at the end of the urinary catheter, which can be adjusted according to the length of the patient's nasal cavity to play a fixed role, while avoiding the occurrence of the oppression of the nasal alar and reducing the pain of the patient; the fixator is a hollow structure, which can also improve the nasal cavity. Ventilation, relieve nasal congestion, headache and other discomfort caused by nasal packing; the fixer is made of silicone material, which can better fit the nasal cavity.

In conclusion, the adjustable nasal airbag hemostatic device of the present invention has a light structure and convenient operation, is suitable for the treatment of clinical epistaxis, and has rapid hemostasis and high comfort.

Description of drawings

FIG. 1 is a schematic structural diagram of the adjustable nasal airbag hemostat of the present invention.

In the picture: 1 urinary catheter, 2 air bag, 3 water injection port, 4 fixator, 5 hemostatic cotton, 6 small holes.

Detailed ways

As shown in FIG. 1 , the adjustable nasal airbag hemostatic device of the present invention includes a urinary catheter 1 and its airbag 2 . The airbag located at the head end of the urinary catheter is connected to the water injection port 3 through a pipeline, the tail end of the urinary catheter is covered with a fixer 4, and the urinary tube on the inner side of the fixator is covered with a wave-shaped chitosan hemostatic cotton; the fixer is a silicone hollow collar; hemostasis Cotton 5 wraps mesh. in,

The urinary catheter is a natural silicone rubber hollow tube with a length of 12CM. The tube runs through the entire device. The cavity is soft and has good biocompatibility. The patient has no foreign body sensation. It can be bent at any angle to facilitate packing into the nasal cavity. Small holes 6 are scattered on the urinary catheter at the place where the hemostatic cotton is covered. When the hemostatic cotton is filled with water, it can prevent water from flowing into the lower part of the catheter.

The capacity of the balloon is 10ml. After placing the urinary catheter, water is injected into the balloon through the water injection port to inflate the balloon, which can prevent the urinary catheter from sliding down. At the same time, the balloon compresses the bleeding site to stop the bleeding, and the balloon can be removed or replaced as needed.

Chitosan hemostatic cotton is used, because it has good biocompatibility and can be degraded in the human body, the degradation products are safe and non-toxic, and its positive charge has antibacterial and anti-inflammatory effects, and the elasticity of the sponge can still be maintained after encountering water; Chitosan also has a good effect of promoting wound healing and inhibiting the growth of fibroblasts and reducing the formation of scars. The wave-shaped hemostatic cotton improves patient comfort.

The fixer is made of silicone material, non-toxic, tasteless, odorless, non-adhesive to human tissue, and has very little reactivity to human tissue. It has good elasticity, high softness, oxygen resistance, anti-aging, mildew resistance, chemical stability, etc. The urinary catheter is pierced through the center of the fixator, and the fixator can be adjusted forward and backward according to the length of the patient's nasal cavity. If the catheter grows out, it can be cut by yourself; at the same time, the cavity in the center of the fixator can improve the ventilation of the nasal cavity and improve the comfort of the patient.

Instructions

1) First determine the bleeding site of the patient, and then select a hemostatic device of the appropriate size according to the patient's age and body shape. Too large or too small will affect the hemostatic effect.

2) Keep the patient in a sitting position with the head slightly tilted back, insert the urinary catheter from the anterior nostril on the side to be filled, insert about 10cm, and inject 10ml of saline through the water injection port to inflate the balloon and compress the post-nasal hemorrhage for hemostasis.

3) Push the fixator forward and insert it into the nasal cavity, adjust it according to the length and comfort of the patient's nasal cavity, adjust it to an appropriate position and fix it at the alar of the nose, and cut off the excess catheter.

4) Pump a little saline and slowly inject it into the cavity in the center of the fixator, so that the hemostatic cotton swells after absorbing water, which plays the role of secondary fixation and hemostasis.

5) Finally, fix the water injection port properly next to the nose, and stick it as close as possible to the nose to avoid falling into the mouth and affecting eating.
