Abstract
The utility model belongs to the technical field of the medical supplies technique and specifically relates to a blood passes through patient's device of taking a blood sample. The blood sampling before the treatment of patient hemodialysis generally has two kinds of methods: 1, like ordinary patient non - fistula side for the limbs blood taking needle take a blood sample, patient generally refuses to adopt this method, 2, after the arteriovenous fistula punctures successfully, follow the tail end of vein needle and open, then open the cap of heparin tube promptly, let blood stay the heparin tube automatically. The harm of doing like this is 1: whole blood collection operation is open easy pollution, the blood sampling volume is wayward, whole blood collection operation is complicated, difficult operation. The utility model discloses a disposable arteriovenous fistula pjncture needle, still include connecting catheters, connecting catheters's one end is equipped with the cap of being connected that links to each other with disposable arteriovenous fistula pjncture needle, connects cap inside and link up with connecting catheters, is equipped with in the connection cap and is connected the internal thread that the outer thread to match on the inner core closed with the disposable arteriovenous fistula pjncture needle other end, connecting catheters's the other end is equipped with and inserts negative pressure base pin head.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of hemodialysis patients blood-taking device.
Background technology
At present, there is a lot of hidden danger and inconvenience during hemodialysis patient blood sampling before the treatment.Patient takes a blood sample before the treatment generally two kinds of methods: 1, take a blood sample at side limbs (non-fistula side) blood taking needle as common patient, the secondary quilt puncture time but a lot of patient is unwilling; They wish alternatively, namely puncture successfully in arteriovenous fistula, open from the tail end of intravenous needle, then open the cap of blood taking tube, allow blood automatically be left to blood taking tube.Such practice harm is a lot, and 1. whole blood collection procedure is open easy pollution, infects, the 2. bad control of blood sampling volume, too much or very few.3. whole blood collection procedure is complicated, not easy to operate.
Summary of the invention
The purpose of this utility model is to provide a kind of hemodialysis patients blood-taking device, and this device can meet patient requests, realizes one-time puncture and can reach two objects, and reduce patient pain, blood collection procedure is airtight, not easily pollutes, and medical worker is easy to operate.
The technical solution of the utility model is: hemodialysis patients blood-taking device comprises disposable arteriovenous fistula puncture needle; Also comprise connection tube; One end of connection tube is provided with the attachment cap be connected with disposable arteriovenous fistula puncture needle, and attachment cap is inner through with connection tube, and the other end of connection tube is connected with and inserts negative tube syringe needle.
Further, the female thread being connected the external screw thread on inner core with the disposable arteriovenous fistula puncture needle other end and matching is provided with in described attachment cap.
The utility model has the advantages that medical worker's handled easily, whole process is airtight pollution-free, and blood sampling volume easily controls, and avoid patient and be punctured secondary, decrease patient suffering, achieve patient satisfaction, nursing staff reduces workload.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is this utility model using state schematic diagram.
Detailed description of the invention
In figure: 1, disposable arteriovenous fistula piercing needle, 2, conduit, 3, connect inner core, 4, attachment cap, 5, connection tube, 6, insert negative tube syringe needle, 7, negative pressure blood collection tube.
As can be seen from Figure 1, hemodialysis patients blood-taking device comprises disposable arteriovenous fistula puncture needle 1; Also comprise connection tube 5; One end of connection tube is provided with the attachment cap 4 be connected with disposable arteriovenous fistula puncture needle, and attachment cap 4 is inner through with connection tube, and the other end of connection tube is connected with and inserts negative tube syringe needle.
The female thread being connected the external screw thread on inner core 3 with the disposable arteriovenous fistula puncture needle other end and matching is provided with in described attachment cap 4.
When this utility model uses, disposable arteriovenous fistula puncture needle is first connected with connection tube 5 by medical worker, gives patient's extracting vein blood according to a conventional method.Then, unload connection tube 5, disposable arteriovenous fistula puncture needle is connected with dialysis pipeline, starts dialysis treatment.
Finally should be noted that: above embodiment is not intended to limit for illustration of the technical solution of the utility model; those skilled in the art modifies to embodiment or carries out equivalent replacement to portion of techniques feature; and do not depart from the essence of technical solutions of the utility model, all should be encompassed within this utility model scope required for protection.
