Description
Technical field
The utility model belongs to medical instruments field, particularly relates to a kind of storage blood device pressure equaliser.
Background technique
With the high speed development of surgical medicine, each training of performing the operation is highly difficult, capital operation continuous development, the mistake in operation
Blood increases increasingly；Massive blood loss caused by surgical procedure is unable to get recycling, will be the very big wave to human blood resource
Take；Autologous transfusion is the blood being lost in operation by collecting in vacuum suction to storage blood device, at present clinically
The storage blood device used is largely without pressure controlled function, and slightly larger just formed to blood constituent of negative pressure suction force is destroyed, to disease
People's safety is poor.
Therefore it needs to research and develop to have the storage blood device to blood conservation function for clinically using.
Utility model content
The utility model mainly solving the technical problems that provide a kind of storage blood device pressure equaliser, be used for from
When body blood recycles, autobalance stores the pressure inside and outside blood device.
The technical solution of the utility model are as follows: preferably to solve above-mentioned technical problem, the utility model uses a skill
Art scheme, provides a kind of storage blood device pressure equaliser, and product includes storage blood tank, pressure control device and stop collar；Its feature exists
In: the storage blood tank is tubular structure, and top is equipped with negative pressure connector, pressure relief opening, blood entry port, and lower part is exported equipped with blood；
Pressure relief opening bottom surface is equipped with plane, is sealed with sealing ring cooperation, and center is equipped with the through-hole that slide for sliding bar, be surrounded by and
The annulus of stop collar cooperation；The pressure control device includes sliding bar, sealing ring and spring；The stop collar is cylindrical body ladder knot
Structure, middle part are equipped with the cylinder that raises upward, top is equipped with concave station contact with spring one end, and center for sliding bar equipped with sliding
Through-hole；Pressure control device is fixed on storage blood tank by the pressure relief opening annulus cooperation on the stop collar and storage blood tank.By above-mentioned
Usage mode when storing blood into storage blood tank using negative pressure, when storing the negative pressure in blood tank higher than design value, stores the atmospheric pressure outside blood tank
It is mobile that sliding bar will be oppressed, sealing ring is separated with pressure relief opening plane, is made to store the inside and outside formation access of blood tank, is played autobalance pressure
The effect of power.
Wherein, the sliding bar is cylindrical body hierarchic structure, and top is equipped with the cylindrical body cooperated with pressure relief opening central through hole；
Middle top surface is equipped with the plane cooperated with sealing ring, and bottom surface is equipped with the plane cooperated with spring one end；Bottom is equipped with and stop collar
The cylindrical body of central through hole cooperation.
Wherein, the material of the sealing ring is TPE, TPU, rubber, silicon rubber.
Wherein, the material of the sliding bar is PC, ABS, PMMA, PP.
The beneficial effects of the utility model are: the utility model is a kind of storage blood device pressure equaliser, have following excellent
Point:
1, adaptable, temperature influences it small.
2, spring structure resets rapidly, securely and reliably after pressure decline.
Detailed description of the invention

Specific embodiment
As shown in Figure 1, it stores blood device pressure equaliser structural schematic diagram for the utility model, product includes storage blood tank
1, pressure control device 2 and stop collar 3；Introduce the connection relationship between the structure type and component of all parts one by one below.
Wherein, the storage blood tank 1 is tubular structure, and top is equipped with negative pressure connector 1-1, pressure relief opening 1-2, blood entry port 1-
3, lower part is equipped with blood and exports 1-4；Pressure relief opening bottom surface is equipped with plane, is sealed with sealing ring 2-1 cooperation, center is equipped with for cunning
The through-hole of lever 2-2 sliding, is surrounded by the annulus cooperated with stop collar 3.
Wherein, the pressure control device includes sealing ring 2-1, sliding bar 2-2 and spring 2-3.
Wherein, the sliding bar is cylindrical body hierarchic structure, and top is equipped with the cylindrical body cooperated with pressure relief opening central through hole；
Middle top surface is equipped with the plane cooperated with sealing ring, and bottom surface is equipped with the plane cooperated with spring one end；Bottom is equipped with and stop collar
The cylindrical body of central through hole cooperation.
Wherein, the stop collar is cylindrical body hierarchic structure, and middle part is equipped with the cylinder to raise upward, and top is equipped with and spring
The concave station of end thereof contacts, center are equipped with the through-hole slided for sliding bar.
Wherein, pressure control device is fixed on storage blood tank by the pressure relief opening annulus cooperation on the stop collar and storage blood tank.
Form using the above structure, in the course of surgery, when carrying out paying vacuum suction recycling to blood, the pressure of vacuum suction
Power is excessive, and when storing the negative pressure in blood filter tank body 1 more than design value, the right-angled intersection slot on 2 dome of pressure valve core i.e. can be certainly
It is dynamic to open, the pressure in tank body 1 is reduced in time, plays the role of protecting blood, and patient is made to obtain the self blood of reliable health
Liquid.
By above-mentioned usage mode, when storing blood into storage blood tank using negative pressure, the negative pressure store in blood tank is higher than design value
When, sliding bar movement will be oppressed by storing the atmospheric pressure outside blood tank, and sealing ring is separated with pressure relief opening plane, make to store the inside and outside formation of blood tank
Access plays the role of self-balancing pressure.The positive protection reinforced on links to blood of adopting various measures, not only
The application of foreign body blood can be reduced, patient's prognosis can also be effectively improved.
