Abstract
The utility model discloses a kind of blood volume changing ratio slide rule, comprise main scale and secondary chi, the middle part of described main scale is provided with the groove that is embedded with secondary chi, the inner surface top of described groove is provided with the rear packed cell volume graduation apparatus of dialysis, the inner surface bottom of described groove is provided with arrow, and the front surface upper and lower of described secondary chi is respectively arranged with dialysis proerythrocyte hematocrit graduation apparatus and blood volume changing ratio graduation apparatus.This blood volume changing ratio slide rule by arranging dialysis proerythrocyte hematocrit graduation apparatus, blood volume changing ratio graduation apparatus, the rear packed cell volume graduation apparatus of dialysis and arrow on main scale and secondary chi, the packed cell volume made it possible to before and after by patients with hemodialysis directly measures blood volume changing ratio, adjust the desirable dry weight of Dialysis scheme according to the blood volume changing ratio obtained in time, decrease the generation of hypotension.
Description
Technical field
This utility model relates to technical field of medical instrument, is specially a kind of blood volume changing ratio slide rule.
Background technology
Patients with chronic renal failure needs row maintenance hemodialysis (HD) to treat (3 times/week), and hemodialysis will remove excessive moisture from Ink vessel transfusing, enters blood carry out replenishment of blood content (BV) by interstitial fluid.The moisture of each removing, namely ultrafiltration volume (UV) is set according to weight in patients increment and dry weight by doctor, dry weight underrating, ultrafiltration volume is too much, full relative deficiency again, pachyemia can be caused, blood volume obviously declines, patients is blood pressure reduction clinically, increased heart rate, can with dizziness, feel sick, the symptoms such as vomiting and tic, prolonged and repeated hypotension can cause the heart, the important organ blood supply insufficiencies such as brain, the life of patient is even made to be on the hazard, also directly dialysis-effect is affected, hypotension is one of modal complication of chronic hemodialysis patients, mainly decline relevant with blood volume, blood volume relative change rate cannot directly measure clinically, the desirable dry weight of Dialysis scheme cannot be adjusted according to this, increase the difficulty for the treatment of.
Utility model content
The purpose of this utility model is to provide a kind of blood volume changing ratio slide rule, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of blood volume changing ratio slide rule, comprise main scale and secondary chi, the middle part of described main scale is provided with a groove, described secondary chi embeds in groove, described secondary chi is made up of transparent material, the inner surface top of described groove is provided with the rear packed cell volume graduation apparatus of dialysis, the inner surface bottom of described groove is provided with arrow, and the front surface upper and lower of described secondary chi is respectively arranged with dialysis proerythrocyte hematocrit graduation apparatus and blood volume changing ratio graduation apparatus.
Preferably, the base of described dialysis proerythrocyte hematocrit graduation apparatus is in same level line with the top margin of the rear packed cell volume graduation apparatus of dialysis.
Preferably, the bottom of described arrow is positioned on the horizontal line at the top margin place of blood volume changing ratio graduation apparatus.
Compared with prior art, the beneficial effects of the utility model are: this blood volume changing ratio slide rule by arranging dialysis proerythrocyte hematocrit graduation apparatus, blood volume changing ratio graduation apparatus, the rear packed cell volume graduation apparatus of dialysis and arrow on main scale and secondary chi, the packed cell volume made it possible to before and after by patients with hemodialysis directly measures blood volume changing ratio, the desirable dry weight of Dialysis scheme is adjusted in time according to the blood volume changing ratio obtained, decrease the generation of hypotension, reduce the difficulty for the treatment of.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described.
Fig. 1 is this utility model perspective view;
Fig. 2 is that this utility model faces structural representation.
In figure: packed cell volume graduation apparatus, arrow 32 after 1 main scale, 2 secondary chis, 21 dialysis proerythrocyte hematocrit graduation apparatus, 22 blood volume changing ratio graduation apparatus, 3 grooves, 31 dialysis.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Refer to Fig. 1-2, this utility model provides a kind of technical scheme: a kind of blood volume changing ratio slide rule, comprise main scale 1, secondary chi 2, dialysis proerythrocyte hematocrit graduation apparatus 21, blood volume changing ratio graduation apparatus 22, groove 3, packed cell volume graduation apparatus 31 after dialysis, arrow 32, the middle part of main scale 1 is provided with a groove 3, secondary chi 2 embeds in groove 3, secondary chi 2 is made up of transparent material, the convenient registration by the registration of packed cell volume graduation apparatus 31 after dialysis and dialysis proerythrocyte hematocrit graduation apparatus 21 contrasts, the inner surface top of groove 3 is provided with the rear packed cell volume graduation apparatus 31 of dialysis, the base of dialysis proerythrocyte hematocrit graduation apparatus 21 is in same level line with the top margin of the rear packed cell volume graduation apparatus 31 of dialysis, the inner surface bottom of groove 3 is provided with arrow 32, the bottom of arrow 32 is positioned on the horizontal line at the top margin place of blood volume changing ratio graduation apparatus 22, the front surface upper and lower of secondary chi 2 is respectively arranged with dialysis proerythrocyte hematocrit graduation apparatus 21 and blood volume changing ratio graduation apparatus 22.
Operation principle: during use, first dialysis proerythrocyte hematocrit and the rear packed cell volume of dialysis of patient is measured, then by the mobile secondary chi 2 be embedded in groove 3, registration after patients with hemodialysis corresponding with on packed cell volume graduation apparatus 31 after dialysis for registration before patients with hemodialysis corresponding on dialysis proerythrocyte hematocrit graduation apparatus 21 aimed at, the registration on the blood volume changing ratio graduation apparatus 22 now indicated by arrow 32 is the blood volume changing ratio of patient.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
