Referring to fig. 1 to 7, a simple assistor for an infusion port 4 includes:
a support frame 1, the lower end of which is provided with a positioning component 11;
the needle containing mechanism 2 is vertically and slidably arranged on the support frame 1 and is used for placing the butterfly wing needle 42;
the adjusting mechanism 3 is arranged on the support frame 1;
when the adjusting mechanism 3 is connected with the needle containing mechanism 2, the needle containing mechanism 2 moves in the vertical direction and rotates simultaneously.
Through long-term care practices, the main reason that the butterfly-wing needle 42 causes pain to a patient during the use of the implanted transfusion port 4 is the needle point shape of the butterfly-wing needle 42. As shown in fig. 7, the needle head of the atraumatic butterfly needle 42 is specially processed, and is similar to a side-hole needle (with an opening on the side wall, point C in the figure), the needle point is slightly bent, so that the puncture septum 41 cannot be cut when the needle seat is punctured, and thousands of punctures are guaranteed without damaging the septum and causing leakage; this also causes the slightly bent needle tip of the butterfly-wing needle 42 to be scraped with the skin of the patient during the needle insertion and needle removal; bringing obvious pain feeling; in addition, the butterfly needle 42 is mainly used for infusion, and its size is large, and its special shape causes slow needle insertion and needle withdrawal, and the pain is aggravated.
First, explaining the puncture process of the lower butterfly-wing needle 42, a nurse usually presses the skin with the left and right three fingers to find the infusion port 4 for positioning, and then hangs the right hand in the air to puncture the puncture compartment 41 of the infusion port 4 into the reservoir 43 of the infusion port 4 after the butterfly-wing needle 42 penetrates the skin.
The device is arranged based on the two-step needle insertion and the two-step needle withdrawal which are further obtained by long-term care practice:
when inserting the needle: after the first positioning step, the patient vertically pierces from the center point, stops for 1S after seeing the empty feeling, and then goes down about 0.5cm according to the subcutaneous fat thickness of the patient. One of them can not be inserted to the bottom so as to avoid the formation of reverse hook due to the contact with the port seat at the bottom. The two-step method is adopted for acupuncture, pain of a patient is relieved when the patient feeds back the acupuncture, and probability of barb of the butterfly wing needle 42 is reduced (barb of the needle head is avoided).
When taking the needle: the harbor seat is stably fixed by using a non-main force hand, the butterfly wing part is held by the main force hand, the butterfly wing needle 42 is slowly pulled out by the aid of the force of the wrist after the butterfly wing part is vertically pulled out to a turning point and is stopped for 1s to eliminate inertia, and then the butterfly wing needle is slowly pulled out according to the radian of the needle body. (pain sensation) inertial injuries need to be avoided.
The specific structural principle and the effect of the device are created as follows:
the first point is as follows: when the needle is inserted, the positioning member 11 of the support frame 1 is placed on the outer side of the skin corresponding to the transfusion port 4 under the skin of a patient by using the left hand to realize positioning instead of traditional manual positioning, then the butterfly wing needle 42 is placed on the needle containing mechanism 2, at the moment, the adjusting mechanism 3 is connected with the needle containing mechanism 2, and in the process of pushing the needle containing mechanism 2 to move downwards, the needle containing mechanism 2 rotates at a small angle, so that the puncture track of the butterfly wing needle 42 on the needle containing mechanism 2 is matched with the shape of the needle point of the butterfly wing needle (the phase is also called as rotary needle insertion), so that when the butterfly wing needle 42 punctures, the needle point cannot be scraped when penetrating the skin, and pain is reduced; the needle holding mechanism 2 is disconnected with the adjusting mechanism 3, and the needle holding mechanism 2 is pushed to move downwards, so that the butterfly wing needle 42 does not rotate any more, but directly pierces the puncture partition 41 of the transfusion port 4 to reach the transfusion groove (the direct needle insertion is performed in the stage).
When taking the needle, the needle holding mechanism 2 is adjusted to be below the butterfly wing needle 42 for supporting, the needle holding mechanism 2 is moved upwards for taking the needle until the needle holding mechanism 2 is connected with the adjusting mechanism 3 (the needle is directly taken at the stage), at the moment, the butterfly wing needle 42 is separated from the transfusion port 4 and is about to be taken out from the needle hole of the skin, the butterfly wing needle 42 slightly rotates upwards, and the taking track of the butterfly wing needle 42 is matched with the needle point shape (the needle is taken in a rotating way at the stage); avoid the needle point scraping the side wall of the needle hole when the butterfly wing needle 42 is directly taken out to cause pain for the patient.
And a second point: the setting of this device not only can reduce patient's misery, can also train and feel. The experienced nurse can insert the needle manually, and the needle insertion can be realized in two steps, namely the rotary needle insertion in the first stage and the direct needle insertion in the second stage. But a less experienced nurse cannot simply master the skill; in the use process of the device, a nurse can gradually grasp the needle insertion degree of the butterfly needle 42 (note that, the transfusion port 4 is usually buried under the clavicle where the skin is thin, and generally, the skin thickness of different patients has no obvious difference), the needle point bending degree of the butterfly needle 42 already determines the needle insertion amount in the needle insertion process, and further determines the connection time and the disconnection time of the adjusting mechanism 3 and the needle containing mechanism 2 of the device. The device does not provide power, and the needle accommodating mechanism 2 needs to be operated manually to move, which is also an important setting for nurses to exercise hand feeling. Moreover, butterfly wing needle 42 puncture itself is gone on under patient's awake state, the patient possesses the sense of trust to nurse's manual operation, if the machine puncture, it is difficult to establish trust, the compliance is poor, can bring very big psychological pressure, it is uncertain that the thorax rises and falls to feed back on patient's health, be unfavorable for butterfly wing needle 42 puncture, this device mainly relies on manual operation, the device mainly plays the guide and helps nurse to carry out the purpose of butterfly wing needle 42 puncture, it is obvious that the patient can more cooperate, also can reduce the pain sense that the puncture leads to when patient's nervousness leads to thorax rise and fall (thorax rise and fall and necessarily accompany the relative motion of butterfly wing needle 42 and skin and then cause pain sense). That is to say, this device not only can reduce the experience demand of nurse when butterfly wing needle 42 punctures, can also help nurse training feel.
And a third point: the port 4 is composed of two parts, an injection base for puncture and a silicone catheter capable of radiographic visualization. Because the silica gel puncture diaphragm 41 membrane ground in 4 base tops in transfusion harbor is inseparable, after the patient's infusion was finished, nurse used the fixed transfusion harbor 4 base of left hand, and right hand often need very hard just can pull out not damaged butterfly wing needle 42, and the right hand often rebounds because of inertia effect unconsciously in the twinkling of an eye when the not damaged needle of butterfly wing was pulled out, very easily leads to nurse to press the acupuncture wound incident of base finger or patient puncture department skin to take place. At this time, our "no-damage needle" not only damages our nursing staff, but also damages our patients, and once infected by various pathogens, the needle will cause heavy impact on the nurses' psychology and economic loss.
When the butterfly wing needle 42 is pulled out, the device can go through two stages of vertical needle receiving and rotating needle receiving; the transition limit of the two phases is the connection of the needle holding mechanism 2 and the adjusting mechanism 3. So when the nurse pulls out the needle, earlier through the direct needle stage of getting, butterfly wing needle 42 takes out from puncture partition 41, the resistance is big, natural nurse is also great hard, during the second stage, flourishing needle mechanism 2 and adjustment mechanism 3 are connected, this inertia that will produce when pulling out the needle with first stage hand carries out offsetting of certain degree, flourishing needle mechanism 2 can shift up and rotate this moment, and not directly shift up, the nurse hand has obvious sensation and then can have the reduction hand strength that prepares to cooperate this device to carry out the rotatory needle of getting of butterfly wing needle 42, will reduce the phenomenon of pulling out the needle resilience, the protection nurse.
A fourth point: the pain sensation is obviously related to the pain time, and the longer the pain time is, the stronger the pain sensation is.
