Abstract
A powder spraying method includes: an accommodating cavity filled with powder is communicated with a pressure gas source, gas is allowed to enter the accommodating cavity, the gas pushes the powder to be sprayed out through a spraying catheter communicated with the accommodating cavity, wherein the pressure intensity at the outlet of the spraying catheter is 0.02-50KPa. The method has the advantages that the method is applicable to wound bleeding caused by injuries or surgeries, and visualized hemostasis of wounds of organs, tissues or parts which are hard to reach can be achieved by the method matching with a hemostasis device and hemostasis material.
Description
Technical field
The present invention relates to a kind of powderject method, particularly relate to a kind of with air-flow drive powder ejection, to answer
For site of injury is realized hemostasis, and it is applicable to the device of the method.
Background technology
At present for the wound hemorrhage caused by wound or operation, no matter using which kind of hemostatic technique, the most too busy to get away
The conventional means of " hemostasis by compression ".Common such as: the adhesive bandage that external wound uses, and various operation
The sthptic sponge of middle use, hemostatic microsphere, hemostasis medical films and the hemostasis yarn etc. made without spinning process.These
Although hemostatic technique is effectively increased hemostasis efficiency, but all external force must be removed after first oppressing a period of time again,
And observe site of injury and the most still have petechia.As hemorrhage in still having, then need to be continuing with hemorrhage, and again press
Compel, until it reaches hemostasis.Not only operate complicated, depend on artificial judgement, for deep layer substantial viscera and chamber
The hemostasis of road deep layer wound surface is difficult to exact operations, causes anthemorrhagic difficulty, especially needs these positions or tissue
Long-time local compression and stop blooding, be unfavorable for the later stage healing of wound.As: nasal sinuses or nasal cavity, the most generally
Use expanded tampon sponge, hemostasis to be difficult to thoroughly, observe after 24 hours need to be oppressed and further take out hemostasis sea without hemorrhage
Continuous.Patient's nose swelling, respiratory tract be not smooth, also results in the timely anthemorrhagic difficulty of operation, and life in patients is poor,
Within 24 hours, observe and need second time to take out, increase the workload of medical personnel.
The appearance of hemostasis gel so that wound hemostasis is improved.But for the wound that amount of bleeding is bigger,
Hemostasis gel is difficult to adhere at short notice wound, it is difficult to realize the purpose of hemostasis in time.
On market, the product that medicament is sprayed on injury with spray pattern, the purpose of this spray pattern is also had to be
Uniformly spraying powder mode is not a kind of Hemostasis.As: Yunnan Baiyao aerosol, it is mainly used in turning round
Wound, for contusion and knife injury etc. it is still necessary to use powder hemostasis (according to aerosol operation instructions).
Summary of the invention
It is an object of the present invention to provide a kind of device utilizing air pressure pulverized powder, in order to will hemostasis
Agent directly acts on tissue wound surface or wound, it is achieved stop blooding in time.
Offer a kind of air pressure injection apparatus application in wound hemostasis is provided, with
It is easy to various tissues or organ wounds are carried out visual lower hemostasia, eliminates the normal operating mode of hemostasis by compression.
It is yet a further object of the present invention to provide a kind of powderject method, drive powder ejection with air-flow,
For site of injury is realized hemostasis.
The technical solution used in the present invention is as follows:
A kind of powderject method, connects the containing cavity being filled with powder with pressure gas source, makes gas enter
Containing cavity, gas push powder is via the injection catheter ejection connected with containing cavity.
Another kind of powderject method, connects the containing cavity being filled with powder with pressure gas source, makes gas warp
Conduit enters containing cavity, and the powder being placed in containing cavity promotes from the bottom to top from the bottom of chamber, through with containing cavity even
Logical injection catheter ejection.
For the realization to wound hemostasis purpose of the beneficially said method, will be filled with the containing cavity of hemorrhage with
After pressure gas source connection, gas push hemorrhage is via the injection catheter ejection connected with containing cavity, and injection is led
The pressure in pipe exit is 0.02Kpa～50Kpa, such as: but be not limited only to 0.02Kpa～0.1Kpa,
0.1Kpa～10Kpa or 0.1Kpa～50Kpa.
In the application, injection catheter is exported just to site of injury, makes powder (such as: hemorrhage) act on wound
While hindering surface, be under pressure constant and continuable gas pressure, it is achieved real to all kinds of wound surface
Hemostasis under executing visually.
Wound is the destroying, including wound and wound surface of the tissue caused by active force or organ.
For different tissues or the wound of organ, the method that the present invention provides can be regulated by valve or pressure
The pressure of device regulation pressure gas source, different with the organizational structure according to different tissues and organ, adapt to hemostasis
Requirement.Such as nasal cavity or sinus tissue, the pressure in injection catheter exit be 0.02Kpa～0.3Kpa or
0.3Kpa～2Kpa；For another example: cerebral tissue, the pressure in injection catheter exit be 0.02Kpa～0.3Kpa or
0.3Kpa～0.8Kpa；And for example: skull, the pressure in injection catheter exit be 0.3Kpa～0.8Kpa or
0.8Kpa～10Kpa, and for example: epidermal tissue, subcutaneous tissue, the pressure in injection catheter exit is
Internal organs, liver and abdominal visceral browser, kidney in 0.02Kpa～0.3Kpa or 0.3Kpa～2Kpa, thoracic cavity and thoracic cavity
Dirty and its pressure of urinary system internal organs is 0.02Kpa～0.3Kpa or 0.3Kpa～5Kpa, and for example: artery hemostasis,
The pressure in injection catheter exit is 0.3Kpa～1Kpa or 1Kpa～50Kpa；And during vein stanch, injection
Pressure at conduit outlet is 0.02Kpa～0.8Kpa or 0.8Kpa～20Kpa.
