Description
Technical field
The present invention relates to a kind of novel through and through wound hemostatic structures, especially a kind of adaptive helical spring hemostatic structures and note
Penetrate formula helical spring hemostasis device.
Background technique
Existing battlefield through and through wound hemostatic treatment mainly uses hemostasis by compression, calcination hemostasis, grease and gauze filling hemostasis etc.
Method, these conventional Hemostasis are also far from satisfying the urgency of through and through wound hemostasis due to the limitation of war conditions or rescued effect
Requirement is rescued, therefore is badly in need of researching and developing one kind new Hemostasis and device to plug a gap.The medical technology of Ore. is public
Department RevMedx has developed the medical device of a syringe-like, and entitled " XStat ", built-in miniature absorbent cotton can change medical officer
The mode for treating bullet wound and shell wound.In use, the miniature absorbent cotton of tens pill shapes is injected wound by medical officer, absorbent cotton is poly- by shell
Sugar processing.Chitosan being capable of clotted blood and to anti-infective.In seconds, absorbent cotton can expand ten times, be closed wound and stop
Blood.But the wounded of this mode bleeding big for battlefield by expanded tampon of sucking blood is breakneck, and material is swollen
Its weakened after swollen, it is difficult to provide wound surface lasting extruding force, function need further perfect.
Summary of the invention
It is a kind of with shape the technical problem to be solved by the present invention is in view of the deficiency of the prior art, design
With the through and through wound hemostatic structures of pressure adaptive.Hemostatic material external film is wrapped in adaptive helical spring by the present invention thus
The surface of deployed configuration makes its store energy using the adaptive helical spring deployed configuration of preceding compression, and when use passes through spiral bullet
Adaptive helical spring deployed configuration is unfolded in spring release elastic potential energy, and real according to the corresponding deformation of wound geometry generation
Existing form adaptive discharges corresponding elastic potential energy according to blood pressure and realizes that pressure adaptive, driving hemostatic material external film make it
It is bonded wound surface, realizes Fast Filling, blood coagulation, hemostasis, saves the life of wounded soldier in fight.
To achieve the above object, the technical solution adopted by the present invention are as follows:
A kind of helical spring hemostatic structures, including hemostatic material external film, which is characterized in that further include an adaptive spiral
Spring deployed configuration, the adaptive helical spring deployed configuration are made of helical spring, support rod and drag-line；The spiral bullet
Spring is in layered distribution, and one every layer, bottom end is fixed on support rod；The hemostatic material external film is fixed on the outer of helical spring
End；Described drag-line one end is fixed on the helical spring, and the other end of drag-line is drawn through the support bar unit.
The helical spring is r, top radius R in no external force lower bottom part radius.
The support rod is cylindrical body, and bottom surface radius is R1.
The hemostatic material external film is pasted and fixed on the outer end of the helical spring.
Three drag-lines are provided on each helical spring, a drag-line one end is fixed on the helical spring list
The outer end of member, another two drag-line one end are fixed on the middle part of coil springs units, and the other end of drag-line is drawn through the support rod.
A kind of injecting type helical spring hemostasis device, the hemostatic structures including syringe and in syringe are special
Sign is: the hemostatic structures include hemostatic material external film and adaptive helical spring deployed configuration, the adaptive spiral
Spring deployed configuration is made of helical spring, support rod and drag-line；The helical spring be in layered distribution, one every layer, bottom end
It is fixed on support rod；The hemostatic material external film is fixed on the outer end of helical spring；Described drag-line one end is fixed on described
On helical spring, the other end of drag-line is drawn through the support bar unit.
There are reaming blades for the front end of the syringe needle, when wound is smaller, cut wound to be put into hemostasis device.
By adaptive helical spring deployed configuration outsourcing hemostatic material external film, elastic potential energy is discharged by helical spring
So that hemostatic material external film is in contact with wound surface and play the role of pressing, realizes hemostasis blood coagulation.
Discharging elastic potential energy by helical spring cooperates the flexibility of hemostatic material external film, it can be achieved that through and through wound wound
Geometric self-adaptation, adaptive filling can be realized according to the shape of wound.
Helical spring can discharge corresponding elastic potential energy according to blood pressure and tissue elasticity and balance with it, thus full
The different wound hemostasis pressure demand of foot, has pressure adaptive.
By tensioning and loosen drag-line, can control the contraction and expansion of hemostatic structures, convenient for the note in its use process
It penetrates and takes out.
The operational version of the helical spring hemostatic structures are as follows: the free unfolded state of helical spring hemostatic structures presence,
Normal operating condition and initial contraction state.Under the free unfolded state, helical spring hemostatic structures are in zero potential energy shape
State；Under the normal operating condition, according to shape of wound corresponding deformation occurs for adaptive helical spring deployed configuration, makes to stop blooding
Material external film is close to wound surface；Under the initial contraction state, helical spring hemostatic structures are stored in syringe.It is raw
For production process i.e. from free unfolded state to initial contraction condition conversion, tensing drag-line makes coil spring contracts, helical spring storage
Adaptive helical spring deployed configuration outsourcing hemostatic material external film is stored in syringe by elastic potential energy.Use process is
It is converted from initial contraction state to normal operating condition, helical spring hemostatic structures is injected into wound by injection device,
When wound is smaller, the reaming blade incised injury mouth of front end of the syringe needle is first passed through, hemostatic structures are then injected into wound again, unclamped
Drag-line, helical spring discharge corresponding elastic strain energy according to locating shape of wound and the pressure being subject to, make adaptive spiral
Spring deployed configuration radially expands, and driving hemostatic material external film makes it be bonded the surface of a wound, to realize quick-acting haemostatic powder function, together
When be also able to satisfy shape and pressure adaptive requirement.Taking-up process is converted from normal operating condition to free unfolded state, is reached
Rope is strained to haemostatic effect post-tensioning, helical spring hemostatic structures are taken out from wound；Drag-line is unclamped, it is automatic to restore to zero gesture
It can state.
