Abstract
The invention discloses a disposable thrombus filter connector. The disposable thrombus filter connector comprises a first connector body, a rotary piston and a second connector body which are communicated. The rotary piston comprises a sliding groove, a piston piece, a handle and a hollow cylindrical outer shell, wherein the sliding groove is formed in the lateral surface of the outer shell, the piston piece is arranged in the outer shell, the handle is arranged outside the outer shell, the piston piece and the handle are connected, and the handle drives the piston piece to rotate through the sliding groove. The disposable thrombus filter connector prevents formed thrombus from falling into blood and causing serious complications, is convenient and practical, avoids the waste of extracted blood of a patient in operation (usually 5-10 ml of the blood of the patient is abandoned due to the worries of micro thrombus), then pulse type tube flushing is carried out to guarantee the smoothness of a retain tube, and the maintenance time is longer.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of disposable thrombosis filter connector.
Background technology
Deep venouspuncture art is applied more and more extensive at present, especially in the outer infusion such as intravenous nutrition and chronic disease (malignant tumor) of surgery intestinal.Deep venouspuncture art indwelling tube is embedding for a long time, generally can retain the 3-6 month, but patient faces the venothrombotic danger of formation in tube chamber like this.
Our traditional dredging method needs multiple syringe to dredge at present, dredge approximately with 3 ~ 4 syringes at every turn, and we extract out blood and syringe used will slattern blood nearly (5 milliliters), our tumor patient especially arrives advanced tumor as everyone knows, and blood is of great rarity.The shortcoming of usual leading method: 1), waste medical resource; 2), blood samples of patients is wasted; 3), have that thrombosis is remaining in vivo to lead to complications.
Summary of the invention
The object of this invention is to provide a kind of disposable thrombosis filter connector, the thrombus breaks loose solving the formation existed in prior art enters blood and the problem of severe complication occurs.
The technical solution adopted in the present invention is, disposable thrombosis filter connector, comprise the first joint, rotary-piston and the second joint that are connected, rotary-piston comprises the cylinder blanket of chute, piston sheet, handle and hollow, chute is arranged at the side of shell, and piston sheet is placed in shell, and handle is placed in outside shell, piston sheet is connected with handle, and handle drives piston sheet to rotate by chute.
Feature of the present invention is also,
Piston sheet comprises fan-shaped filter net sheet, and be provided with to two ends extension arc-shaped side along the circular arc place of filter net sheet, the home position of filter net sheet is fixed on its center line place of shell, and the first joint and the second joint to be arranged on shell and to be positioned at the non-central line position of shell.
Be provided with the first draw-in groove inside shell and near chute place, the arc-shaped side of piston sheet is arranged in the first draw-in groove.
The side of shell is provided with the second draw-in groove, the second draw-in groove communicates with chute.
First joint, shell and the second joint adopt makrolon material to make.
Filter net sheet is by polyamide 6-6 or meet that material that the chapter 4 in GB8369-2005 standard specifies is refining to be formed.
The invention has the beneficial effects as follows: the thrombus breaks loose that apparatus of the present invention avoid the formation of enters blood, there is severe complication, and it is convenient, practical, avoid the waste of patient's suction blood in operating (because worrying have microthrombus often to abandon blood samples of patients 5-10ml), and then pulsed washing pipe, to ensure that indwelling tube is unobstructed, hold time longer.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The invention provides a kind of disposable thrombosis filter connector, as shown in Figure 1, comprise the first joint 1, rotary-piston 2 and the second joint 3 that are connected, as shown in Figure 2, rotary-piston 2 comprises the cylinder blanket 7 of chute 4, piston sheet 5, handle 6 and hollow, and chute 4 is arranged at the side of shell 7, piston sheet 5 is placed in shell 7, handle 6 is placed in outside shell 7, and piston sheet 5 is connected with handle 6, and handle 6 drives piston sheet 5 to rotate by chute 4.
As shown in Figure 4, piston sheet 5 comprises fan-shaped filter net sheet 12, and be provided with to two ends extension arc-shaped side 13 along the circular arc place of filter net sheet 12, the home position of filter net sheet 12 is fixed on its center line place of shell 7, and the first joint 1 and the second joint 3 are positioned at the non-central line position of shell 7.
Be provided with the first draw-in groove 8 inside shell 7 and near chute 4 place, the arc-shaped side of piston sheet 5 is arranged in the first draw-in groove 8, makes whole device be placed in sealing state.
As shown in Figure 3, the side of shell 7 is provided with the second draw-in groove 9, second draw-in groove 9 to communicate with chute 4, for the position of fixed handle 6.
