The portable intra-bone marrow injection system that depth is monitored.
Background technology
Currently, during most of clinical emergency treatment, when especially being rescued to critical patient, venous transfusion channel is established, and
When administration can be rescue try to gain time precious to one.But often there are some Critical Ill Patients due to originals such as dehydration, shock, massive haemorrhage
Cause, cannot quickly and effectively establish vein it is logical when, lose best delivery time, rescue failure.In this case, by pole
Ossis channel is established in short time, it is ensured that it is the key that rescue that the drug and liquid for the treatment of are given in time.In the past few decades
In, when being become difficult using traditional intravenous transfusion methods for some damage is serious or sb.'s sickness becomes critical patients or impossible
When, in a kind of ossis suitable for children and adult the traditional technology of (IO) infusion cause again people interest and
Concern.This method safety, simple, quick and effective, it can be by fast and reliable cyclic reconstruction, and then relieves several
Injury suffered by every emergency treatment shock patients.
The rete venosum for having many non-atrophys in ossis, shock or due to wound massive blood loss patient's body often
The rete venosum of periphery can be collapsed or be closed, and in such cases, the marrow intraluminal vein net among bone protection because
Its special bony structures remains able to same body circulation and keeps directly and completely connecting.The pressure of blood vessel in ossis is about
For 35/25mmHg, it is equivalent to the one third of body mean arterial pressure.These close and numerous non-atrophics in ossis
Tiny veins network can quickly be absorbed just as sponge is filled into surrounding liquid, and by its rapid transport to body circulation
Among.This special anatomical structure of marrow intraluminal vein just can be by rapid transport to body at the liquid or drug of IO infusions
The basic reason for recycling and being absorbed and utilized.
It has been further filled with the marrow being made of blood, hematopoietic cell network and connective tissue in ossis, has included mainly red
Two kinds of marrow and yellow marrow.Wherein, red marrow is predominantly located in the netted cancellous bone at long bone both ends, and the blood for including high concentration is thin
Born of the same parents；And yellow marrow is predominantly located in the central lacuna of adult long bone.
Existing intra-bone marrow injection is not suitable for field work, lacks portable component, is unsuitable for the spies such as army
The needs in different field.When intra-bone marrow injection, the dynamics of puncture relies on operator to perceive entirely, effectively cannot observe and judge.It needs
Want a kind of easy to operate, easy to carry, portable intra-bone marrow injection system for being monitored to the dynamics and depth of puncture.
