Technical Field
The utility model relates to an implanted device technical field that doses especially relates to a be applied to implanted device's of dosing pipe auxiliary fixation structure.
Background
The implanted drug delivery device is a venous transfusion device which can be completely implanted into a body, a catheter is placed in a superior vena cava of the body by a percutaneous puncture method by using an operation method, the rest catheter and a port are buried in subcutaneous tissues, and a circular bulge (corresponding to the position of the port) can be touched on the body surface of a patient; when in treatment, the atraumatic needle vertically punctures into the liquid storage groove of the harbor seat through the skin, and can be used for infusing various medicines, supplementing liquid, supporting treatment of nutrition, blood transfusion, blood sample collection and the like. The implanted drug delivery device provides a reliable venous channel for a patient needing long-term infusion treatment, can be used for blood sample collection, can be implanted once, can reduce the pain and difficulty of repeated puncture, is simple to operate, and is implanted subcutaneously, so that the risk of infection is reduced.
During the implantation process of the actual implantable drug delivery device, the steps are as follows:
a. selecting a puncture site: the puncture site is generally selected from internal jugular vein, subclavian vein, femoral vein and external jugular vein, and the puncture site needs to be noted as follows: avoiding anatomical distortions, lesions and localized sites of infection, tumor invasion, radiotherapy, or the presence of other intravascular devices (pacemakers, dialysis catheters, etc.); moreover, the puncture position depends on the related factors such as the habit of the operator, the condition of the patient, the requirement of the patient, and the like. The right internal jugular vein is superior to the left internal jugular vein when selecting the puncture site because: 1. the right internal jugular vein is almost in a straight line with the superior vena cava of the innominate vein; 2. the right internal jugular vein has short and straight route to enter the superior vena cava, and the left side is tortuous; 3. the right pleura parietal is slightly inferior to the left; 4. the right side has no thoracic duct; 5. the catheter is pressed against the wall of the superior vena cava; 6. mistakenly enter other blood vessels;
b. venipuncture: before venipuncture is performed: flush implantable drug delivery device accessories (catheters, harbors, guidewires, etc.) with 250ml of saline plus 1 heparin (1.25 ten thousand units) in heparin saline;
c. placing a guide wire and removing the puncture needle;
d. by means of guide wires, inserting dilators/sheaths
e. Inserting the catheter, tearing the sheath open;
f. establishing a subcutaneous containment pocket;
g. establishing a subcutaneous tunnel;
h. passing a catheter through the tunnel;
i. placing and fixing the port seat in the subcutaneous holding pocket, and then connecting the end part of the catheter with the port seat;
j. the incision is sutured.
It should be noted that, in the implantation process of the implantable drug delivery device, the position of the subcutaneous containing bag for the implantation port seat deviates from the venipuncture point, a tunnel for the catheter to pass through is opened between the position of the subcutaneous containing bag and the venipuncture point, the tunnel and the puncture vein form an included angle, namely, the catheter passing through the puncture point forms an included angle, the included angle can cause the catheter to be broken and blocked, and once the catheter is broken and blocked, the transfusion and blood sample collection operation of the implantable drug delivery device can be influenced.
Therefore, in order to solve the problem that the catheter of the implantable drug delivery device is broken and blocked at the included angle, it is necessary to design and develop a catheter auxiliary fixing structure applied to the implantable drug delivery device.
