Abstract
The utility model discloses a disposable arterial intubate catheter, which is mainly composed of an inside and an outside concentric catheters. The outside catheter is a medical flexible catheter, wherein, both ends of which are relatively sealed, and only the tops of both ends of the outside catheter are provided with retractable pinholes. The front end and the side wall of the inside catheter are provided with a plurality of drug infusing pinholes. When the intubating chemotherapy is used for patients, the inside catheter is extended from the sealed outside catheter to infuse the drug, and the inside catheter can be retracted into the sealed outside catheter after the drug is infused. The disposable arterial intubate catheter, which can prevent the thrombus of the drug infising pinholes from being clogped and hematorrhea due to catheter pulling action has the advantages of tight structure, convenient drug infusion and firm catheter sealing. The utility model is suitable for arterial intubating chemotherapy of various malignancy.
Description
This utility model relates to malignant tumor arterial chemotherapy device, is meant a kind of intubate conduit that is used for arterial chemotherapy especially.
The arterial cannulation chemotherapy is to be used for one of main method for the treatment of malignant tumor on the present clinical medicine.Owing to still lack special-purpose intubate conduit on the market, how most of now hospital replaces with continuous epidural catheter, various cardiac catheter, ureteral catheter and medical infusion lines with anesthesia, this just following problem occurs inevitably: injection inconvenience, easily outside the discharger, cause skin and soft tissue necrosis; This type of conduit is put for a long time and is stayed in the tremulous pulse, and its medicine-pouring hole needs repeatedly regularly to inject heparin liquid easily by thrombus obstruction, has not only increased nurse's labor intensity, and the heparin prolonged application is brought adverse consequences easily to the change of human body clotting mechanism; Be not suitable for carrying out artery embolization for treatment, easily cause massive hemorrhage, tube sealing difficulty after the tube pulling.
The purpose of this utility model provides a kind of arterial cannulation conduit, and its medicine-pouring hole is difficult for blocking, and can give patient's injection chemotherapy safely and reliably; And be easy to tube sealing, the while also is convenient to the artery embolization for treatment after the chemotherapy.
For realizing that the arterial cannulation conduit that this purpose this utility model adopts includes outer catheter, inner catheter, be inserted in the steel wire inner core in the inner catheter and the gauge tap of control inner catheter herb liquid flow etc., outer catheter is the airtight relatively flexible pipe for medical purpose in two ends, only respectively has a contractile pin hole at its top, two ends; Front end and sidewall that inner catheter inserts in the tremulous pulse have several medicine-pouring holes, and its rear end is connected with medicine-filling device; Inner catheter can pass pin hole and stretch out in outer catheter or indentation.
Advantage of the present utility model is to have adopted the porous injection, has reduced the injection resistance, and inner catheter is totally lost and returns in the airtight outer catheter behind the medicinal liquid, has prevented the obstruction of medicine-pouring hole, does not need repeatedly to inject heparin at once; Alleviated the pay effect of heparin, reduced nurse's labor intensity human body; Because outer catheter is airtight relatively, prevented backflow of blood again, tube sealing is firm; Also be suitable for the artery embolization for treatment after the chemotherapy.
Below in conjunction with accompanying drawing this utility model is further described.
Accompanying drawing is this utility model structural representation.
(1) is outer catheter among the figure, and available medical rubber hose is made, and its two ends are sealed, and only respectively has a contractile pin hole (8), and blood can not flow backwards by this pin hole.(2) be inner catheter, available medical silicone tube is made, it can pass pin hole (8) and move freely in outer catheter, its medicine-injecting end top and sidewall have several medicine-pouring holes (9), be convenient to reduce the injection resistance and prevent the medicine-pouring hole thrombus obstruction, there is one section scale sign (4) to be used to understand the advance and retreat degree of depth of inner catheter on the sidewall of the one section inner catheter (2) after being positioned at outer catheter (1) afterbody, be connected to one section medical rubber flexible pipe (5) thereafter, one flow gauge tap (6) is housed on the band tubing (5), this switch can also prevent backflow of blood and air admission, the rearmost end and the medicine-filling device of inner catheter (2) are complementary, on have one to be used for pipe sealing rubber closure (7), in inner catheter (2), also have a steel wire inner core (3) to use as support and mediation tube chamber.When to patient's injection, promoting inner catheter (2) makes its medicine-injecting end stretch out pin hole (8), stretching out the degree of depth can be read by scale (4), can inject various medicinal liquids this moment, annotated the heparin liquid that reinjects a time behind the medicinal liquid, medicine-injecting end is returned in the enclosed cavity of outer catheter, shut switch (6), get final product with rubber closure (7) tube sealing.
Claims (1)
- A kind of disposable arterial cannulation conduit, include outer catheter (1), inner catheter (2), be inserted in the steel wire inner core (3) in the inner catheter (2) and the gauge tap (6) of control inner catheter (2) herb liquid flow etc., it is characterized in that: outer catheter (1) is the airtight relatively flexible pipe for medical purpose in two ends, only respectively has a contractile pin hole (8) at its top, two ends; Front end and sidewall that inner catheter (2) inserts in the tremulous pulse are opened in several medicine-pouring holes (9), and its rear end is connected with medicine-filling device; Inner catheter (2) can pass pin hole (8) and stretch out or indentation in outer catheter (1).
