Description
Technical Field
The utility model relates to the technical field of infusion ports in medical treatment, in particular to an auxiliary device for preventing needle puncture during the needle withdrawal of an atraumatic needle of an infusion port.
Background
Intravenous infusion port, i.e., port implantation, is a therapeutic procedure in which an implantable intravenous administration set is placed subcutaneously in the human body, and is clinically useful for patients requiring prolonged infusion and chemotherapy.
An implantable central venous transfusion PORT (PORT) consists of an injection base for puncture and a silica gel catheter capable of being subjected to radiography. When a patient implanted with an intravenous transfusion port is subjected to transfusion, and a nurse pulls out a non-invasive needle of the transfusion port according to a clinical traditional method, the thumb, the index finger and the middle finger of a non-dominant hand of the nurse are required to be fixed on a transfusion port base, and then the dominant hand pulls out the needle, at the moment, the nurse can unconsciously rebound due to inertia effect while pulling out the needle vertically due to high base resistance, so that the non-dominant hand on the fixed transfusion port base is easy to prick, and the operating nurse is damaged by the needle; once stabbed, there is a risk of infection by various pathogens of the patient, thus imposing a heavy physical and psychological burden on the nurse.
For this reason, some auxiliary devices have been developed to avoid or reduce the risk of being pricked during needle withdrawal, but they suffer from certain drawbacks, such as:
an auxiliary device for removing needle of transfusion harbor with the bulletin number of CN206577199U is provided, when in use, the opening groove of the device must be slid into and clamped at two sides of the needle to remove the needle. To this end: the needle cannot be pulled out in one step, and the auxiliary device is plugged in after a part of the intact needle is pulled out, so that the auxiliary device can be pulled to pull out the needle; this procedure is clinically undesirable and unsafe, except for the first insertion of an atraumatic needle, where a longer length of needle is intentionally exposed. Such an auxiliary device is therefore inconvenient to use.
When the infusion port needle extractor with the publication number of CN110613871A is used, the fork head of the needle extractor is inserted under the butterfly wing needle handles at the two sides of the needle head through the fork opening, and then the puncture needle is picked out by applying external force through the handle, or the puncture needle is pried out by using the other hand as a fulcrum to carry out lever type prying. This needle extractor has the following disadvantages: the contact part between the bottom of the fork head and the human body is small, and the comfort is poor for a thin patient when the needle is pulled out, and in addition, the structure of the needle pulling device is complicated, and the production cost is high.
To this end, the present inventors developed an auxiliary device for preventing needle stick injuries that is simpler in structure and more practical.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, provides the needle penetration prevention auxiliary device for the non-invasive needle pulling of the transfusion harbor, which is practical, reasonable and simple in structure, comfortable, simple and convenient to operate, is suitable for the non-invasive needles of different types of transfusion harbors and different types of transfusion harbors, and is beneficial to clinical popularization.
In order to solve the technical problems, the utility model adopts the following technical scheme:
an auxiliary device for preventing needle puncture during needle drawing of an atraumatic needle of an infusion port comprises a strip-shaped body in a sheet shape, wherein a bayonet is formed in the middle of one side of the body in the length direction.
In the improvement scheme of the auxiliary device for preventing needle puncture during needle drawing of the non-damaged needle of the transfusion harbor, grooves are respectively arranged on two sides of the length direction of the body.
In the improvement scheme of the auxiliary device for preventing needle puncture during the needle drawing of the non-damaged needle of the transfusion harbor, the upper edge of the bayonet is provided with an upward inclined chamfer; the bayonet is provided with a downward inclined chamfer on the lower edge thereof.
In the improvement scheme of the needle penetration prevention auxiliary device when the needle is pulled out from the non-damaged needle of the transfusion harbor, the inclined surface of the lower inclined chamfer is larger than the upper inclined chamfer.
Compared with the prior art, the utility model has the beneficial effects that: because the auxiliary device is in a sheet shape, when in use, the bayonet of the auxiliary device is horizontally aligned with the needle head of the atraumatic needle inserted in the transfusion port and then horizontally clamped outside the needle head; then, the index finger and thumb of the left hand (non-dominant hand) are respectively pressed on the two sides of the body, and the middle finger is pressed on the body in front of the bayonet, so that after three fingers of the left hand are pressed on the body, the right hand (dominant hand) can be pinched on the needle head from the two sides and the needle head is pulled outwards; in addition, because the auxiliary device is in a sheet-shaped integrated shape, the production cost is low, the contact surface with a patient is relatively large, the outline is attached to the skin of the patient, the force is balanced and the stability is high during pressing, so that when the auxiliary device is pressed on the patient implanted with the intravenous transfusion port, even for a thin patient, obvious uncomfortable feeling is not brought, and the comfort level of the patient during needle drawing is improved.
