Description

Time-counting injector for maintaining blood filtering pipeline

Technical Field

The utility model relates to a time-using injector for maintaining hemofiltration pipelines, which belongs to the technical field of medical instruments.

Background

Continuous Renal Replacement Therapy (CRRT) is a therapeutic means that a large amount of Replacement fluid is given while blood of a patient passes through a high-permeability filter, and excess water, various metabolites, drugs, poisons and the like in the body are continuously removed, so that the advantages of effectively maintaining and improving the environment in the body and the like are achieved. Prior to CRRT treatment, a patient typically temporarily establishes a dual lumen access to introduce blood into the CRRT machine for circulation. The national kidney foundation for renal disease prognosis quality initiative organization (KDOQI) in the clinical practice guidelines for Acute Kidney Injury (AKI) of 2012 suggests that maintaining a CRRT blood flow rate of 200ml/min may satisfy all CRRT patterns. Therefore, the artery end (blood leading end) of the double-cavity blood filter tube should have a blood leading speed at least meeting 200ml/min, and even when the blood returning from the artery end of the blood filter tube is drawn by using a syringe, at least 20 ml of blood can be drawn in 6 seconds, so that the patency of the blood filter tube can be proved, and the test is also called as a 6-second test. It has been suggested that the patency of the patient's blood filter circuit should be determined each time before the CRRT is commissioned. In actual clinical work, however, it is difficult for a nurse to time the "6 second test" of the blood filter pathway while withdrawing blood. And at present, the flow rate of the injector is controlled by a micro pump, the related technology of the flow rate during the pumping back of the injector is lacked, and the convenience of the micro pump is far from the convenience of the injector.

Detailed Description

The present invention will be further described with reference to the following specific drawings and examples.

As shown in fig. 1 to 6, the embodiment discloses a time-sharing injector for maintaining a hemofiltration pipeline, which comprises an injector needle cylinder 1, an injector pintle 2, an installation clamping seat 3 and a timer 4, wherein the installation clamping seat 3 is used for being installed at the tail end of the injector pintle 2, the installation clamping seat 3 is circular and has the size matched with that of the tail end of the injector pintle 2, and four claws 5 used for being clamped on four reinforcing ribs of the injector pintle 2 are arranged on the lower surface of the periphery of the installation clamping seat 3; the timer 4 is fixedly installed on the upper surface of the installation clamping seat 3, the outer shell of the timer 4 is in a flat cylindrical shape, the size of the outer shell is matched with that of the tail end of the pintle, a display screen 6 and a timing button 7 are arranged on the outer shell, timing is started when the timing button 7 is pressed down, timing is stopped when the timing button is loosened, and the timing button returns to zero when the timing button is continuously pressed twice.

When the syringe needle bolt is used, the mounting clamping seat 3 is firstly mounted at the tail end of the syringe needle bolt 2, and the four claw hooks 5 on the periphery of the mounting clamping seat 3 are clamped on the four reinforcing ribs of the syringe needle bolt 2, so that the fastening and mounting of the mounting clamping seat 3 are realized. The timer 4 is then mounted on the upper surface of the mounting socket 3. Clinical nurse uses the syringe to extract blood filter tube artery end when returning blood, syringe cylinder 1 is held to one hand, syringe pintle 2 is taken back to the other hand, press down timing button 7 in the time of syringe pintle 2 is taken back, timer 4 begins the timing, show the time of taking back on the display screen 6, stop the pumpback when 6 seconds, loosen timing button 7 simultaneously, the timing stops, just so can accomplish to take back blood and timing accurate synchronization, thereby can accurately assess whether this blood filter tube can accomplish "6 seconds are experimental", facilitate for clinical work, improve the unobstructed aassessment accuracy of blood filter tube. After the timer 4 is used, the zero can be reset by pressing two timing buttons 7.
