Abstract
The utility model discloses a device is pulled out in special needle installation of implanted device of dosing, it relates to medical instrument technical field. The inner core is inserted into the shell and matched with the shell piston, a groove is formed in the bottom of the inner core, and the groove is clamped and fixed with a butterfly needle head of the special needle; the bottom of the shell is provided with a hole matched with the groove, and the tail of the inner core is connected with a push-pull handle. The utility model has the advantages of reasonable design for medical personnel do not need the special needle of direct contact just can accomplish the operation process that inserts and pull out of special needle in operation process, thereby the reduction that increases iatrogenic source nature infection's risk.
Description
Technical Field
The utility model relates to a medical instrument technical field, concretely relates to device is pulled out in special needle installation of implanted device of dosing.
Background
The implanted drug delivery device is also called as an infusion port clinically and is mainly used for chemotherapy of tumor patients, and is used for reducing pain caused by multiple times of puncture and peripheral blood vessel damage. After the implanted drug delivery device is implanted into the subcutaneous part of a human body, the infusion of the liquid medicine needs to be completed through puncturing the injection base. In order to reduce the falling debris generated during the puncturing process and prolong the service life of the device, an atraumatic special needle, namely a special needle for an implanted drug delivery device, is required. The special needle for the implanted drug delivery device which is commonly used clinically mainly comprises a puncture needle, a fixed wing, an extension tube, a buckle clamp, a needle-free connector and the like. Medical personnel need wear aseptic gloves under aseptic condition and operate, because the syringe needle pierces the base after the syringe needle and the base combine very closely, need use great strength when pulling out the needle, consequently, sharp needle point often causes medical personnel's hand to stab easily to increase medical personnel's iatrogenic risk of infecting. At present, no device for completing the installation and the removal operation of the special needle of the implanted drug delivery device exists, so that a special needle installation and removal device for the implanted drug delivery device needs to be designed to complete the operation, reduce the direct contact between a medical worker and a needle head during the operation, protect the medical worker and reduce the infection risk.
Disclosure of Invention
To exist not enough on the prior art, the utility model aims to provide a device is pulled out in special needle installation of implantable device of dosing, structural design is reasonable for medical personnel do not need the special needle of direct contact just can accomplish the operation process that inserts and pull out of special needle in operation process, thereby the reduction that increases the risk of iatrogenic infection.
In order to achieve the above purpose, the present invention is realized by the following technical solution: a special needle mounting and pulling device for an implantable drug delivery device comprises an inner core and a shell, wherein the inner core is inserted into the shell and matched with a piston, the bottom of the inner core is provided with a groove, and the groove is clamped and fixed with a butterfly needle head of the special needle; the bottom of the outer shell is provided with a hole matched with the groove, and the tail of the inner core is connected with a push-pull handle.
Preferably, the cross section of the groove is T-shaped.
The utility model has the advantages that: the utility model has the advantages of reasonable design, design into the structure of syringe, convenient operation can make medical personnel not need the special needle of direct contact just can accomplish the operation process that inserts and pull out of special needle in operation process to the reduction that increases the risk of iatrogenic source nature infection.

Detailed Description
In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.
Referring to fig. 1 to 4, the following technical solutions are adopted in the present embodiment: a special needle mounting and pulling device for an implantable drug delivery device comprises an inner core 1 and a shell 2, wherein the inner core 1 is inserted into the shell 2 and matched with the shell 2 in a piston manner, the bottom of the inner core 1 is provided with a groove 3, and the groove 3 is clamped and fixed with a butterfly needle head 4 of the special needle; the bottom of the outer shell 2 is provided with a hole 5 matched with the groove 3, and the tail of the inner core 1 is connected with a push-pull handle 6.
It is noted that the cross section of the groove 3 is T-shaped.
The device of this embodiment can be used for insertion (mounting) and removal of a dedicated needle, respectively.
And (3) an insertion process: the butterfly wing of the special needle is clamped into the groove, after the butterfly wing is tightly combined, a round bottom support (a base of the infusion port) 7 is used for positioning, a puncture point is determined, the center of a circle is the puncture point, a push-pull handle 6 at the tail part of the inner core is pushed and pressed for puncture, and then the device is removed from a side hole, so that the installation operation can be completed.
The pulling-out process comprises the following steps: the bottom groove is sleeved into the butterfly wing of the special needle to sleeve the special needle, and the tail part of the inner core is pulled backwards to complete the pulling-out operation of the special needle.
The foregoing shows and describes the basic principles and principal features of the invention, together with the advantages thereof. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only illustrative of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
