The utility model content
In view of this, a kind of pressure suit with blood sampling system is provided, can takes a blood sample again by measuring blood pressure, and can avoid causing the problem of anemia because of repeatedly drawing blood.
A kind of pressure suit with blood sampling system; The conduit that it comprises pressure bag, be used for being connected with human vas, the monitor that is connected the pick off that is used for sense blood pressure with conduit and is connected and receives the blood pressure signal that senses with pick off; Said pressure bag is connected to said pick off, and the pressure suit comprises that also one is connected in the hemostix that is used to take a blood sample in the passage of said conduit and is communicated to conduit and the syringe between pick off and hemostix.
Further, said conduit is provided with a valve on the passage between pick off and the said syringe.
Further, said valve is first three-way valve.
Further, said syringe is connected to said conduit through one second three-way valve.
Further, said pick off is connected to monitor through the line plug that leads.
Further, said pick off is connected to said pressure bag through a transfusion device plug.
In the pressure suit of above-mentioned band blood sampling system, in said pick off is connected to the catheter channel of human vas, hemostix is set, thereby the pressure suit can be taken a blood sample again by measuring blood pressure.And, when taking a blood sample,, flow into hemostix and take a blood sample through syringe pump blood, after gathering completion, through pushing back syringe, unnecessary blood is failed back to patient again again, avoid causing the sufferer anemia because of repeatedly drawing blood.
Description of drawings
To combine accompanying drawing and embodiment that this utility model is described further below, in the accompanying drawing:
Fig. 1 is the structural representation of pressure suit of the band blood sampling system of this utility model embodiment.
The specific embodiment
For the purpose, technical scheme and the advantage that make this utility model is clearer,, this utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation this utility model, and be not used in qualification this utility model.
See also Fig. 1; The pressure suit 10 of the band blood sampling system of this utility model embodiment is shown; The conduit 12 that it comprises pressure bag (figure do not show), be used for being connected with human vas (scheming not show), the monitor 14 that is connected the pick off 13 that is used for sense blood pressure with conduit 12 and is connected and receives the blood pressure signal that senses with pick off 13; Pressure bag is connected to pick off 13, and pressure suit 10 comprises that also one is connected in the hemostix 15 that is used to take a blood sample in the passage of conduit 12 and is communicated to conduit 12 and the syringe 16 between pick off 13 and hemostix 15.
Pressure bag can adopt existing pressure bag, is used for before pressure measurement, draining air towards Xian's pick off pipeline on the one hand; When being used for pressure measurement (more be used to survey arterial pressure) on the other hand,, need avoiding blood to reflux with the inflating bag pressurization and get into the pick off pipeline because of arterial pressure is big.Particularly, pick off 13 is connected to pressure bag through a transfusion device plug 17.Be provided with chip (figure do not show) in the pick off 13, directly be used for contacting pressure with sensing blood with blood.Pick off 13 is connected to monitor 14 through the line plug 18 that leads.
Further, conduit 12 is provided with a valve on the passage between pick off 13 and the syringe 16, and this valve is first three-way valve 121.Syringe 16 is connected to conduit 12 through one second three-way valve 122.
As shown in the figure, when needing to measure blood pressure, conduit 12 is connected to human vas; Keeping first three-way valve 121 and second three-way valve 122 is open mode (closing to the passage of syringe 16), and when in pick off 13 cavities during filling liquid (being blood), the pressure of liquid directly acts on the chip; Chip gets final product this pressure of perception; Under the situation of energising, and can convert pressure to the signal of telecommunication and be transferred on the monitor 14, monitor 14 can directly show this force value.When needs are taken a blood sample, at first close first three-way valve 121, rotate second three-way valve 122; Make syringe 16 and the conduit 12 that connects human vas communicate; Syringe 16 handles 162 are taken out backward, and blood flows in the body between hemostix 15 and the human body, then through hemostix 15 blood sample collections.After gathering completion, syringe 16 handles 162 are pushed away (promptly pushing back syringe 16) forward, unnecessary blood is failed back again given patient, avoid causing the sufferer anemia because of repeatedly drawing blood.
