Abstract
Description
TECHNICAL FIELD
[0001] The application provides a needle-stick injury prevention device for an implantable central venous infusion port, and relates to the technical field of medical devices. BACKGROUND
[0002] A totally implantable venous access device (TIVAD), also known as a port, is a closed infusion system implanted in a patient's body and placed in the patient's vein, and has become a widely used and safe infusion device in China.
[0003] The port mainly consists of a catheter and a injection seat, and is mainly used for infusion of antitumor drugs, parenteral nutrition, blood products, etc. The injection seat is made of special silicone material. Medical staff can connect the infusion and the blood vessel by using a matched atraumatic needle to puncture the injection seat percutaneously. The port can be repeatedly punctured without leakage, avoids the pain caused by repeated puncture of the patient, and can be used safely for a long time. The port needs to be maintained regularly, and the atraumatic needle needs to be removed by medical staff at the end of treatment. Because the injection seat of the port body is made of tight material of high compression silicone, it can clamp the atraumatic needle, and the atraumatic needle has a certain curvature, which causes the medical staff to have limited fixation of the base during the removal process, and the resistance is large, resulting in uneven force, pulling the injection seat, and the possibility of pulling pain or skin scratches. Clinically, medical staff mostly use the left hand three-finger method to fix the port body base, and the right hand to vertically remove the atraumatic needle. When removing, a large force is needed, so the hand holding the injection seat and the hand removing the needle are very strong at this time. The hand holding the injection seat is through the skin of the human body during the clamping process, so the port body may be turned over due to the force during removal. In addition, during the needle removal process, the hand removing the needle will rebound due to inertia, and the hand holding the injection seat has not been moved away at this time, so the hand removing the needle may be stabbed by the needle due to the rebound, causing needle stick injury and affecting work efficiency.
[0004] Therefore, it is urgent to design a safe removal protection device for the atraumatic needle of the port, which can effectively solve the problem of difficult removal caused by the difficulty in fixing or limited fixing force of the port base, avoid the occurrence of needle stick injury of medical staff, and relieve the pulling pain and skin scratches of the patient during the needle removal process.

For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0023] The application provides a needle-stick injury prevention device for an implantable central venous infusion port, which is used for protecting the hands of medical staff when the medical staff removes the needle of the infusion port; see Figure 1 and Figure 2 The device comprises a left-hand protection finger sleeve 100 and a right-hand protection finger sleeve 200. The left-hand protection finger sleeve 100 comprises a left-hand thumb sleeve 110, a left-hand index finger sleeve 120 and a left-hand middle finger sleeve 130. The right-hand protection finger sleeve 200 comprises a right-hand thumb sleeve 210 and a right-hand index finger sleeve 220, which are different from the left-hand protection finger sleeve 100. The reason for the different design is that, in clinical practice, medical staff generally uses the left hand to fix the port body base and uses the right hand to vertically remove the non-injury needle. Therefore, the needle-stick injury prevention device for the implantable central venous infusion port provided by the application is a simplified protection structure, which avoids the burden on the hands of medical staff and provides a structure scheme of a three-finger left-hand protection finger sleeve and a two-finger right-hand protection finger sleeve.
[0024] In further embodiments, in order to ensure the needle-stick injury prevention effect, a needle-stick injury prevention layer 140, 240 is arranged on the surface of the left-hand thumb sleeve 110, the left-hand index finger sleeve 120, the left-hand middle finger sleeve 130, the right-hand thumb sleeve 210 and the right-hand index finger sleeve 220. When the medical staff vertically removes the non-injury needle from the injection seat, a large force is needed, for example, the left hand holding the injection seat and the right hand removing the needle need to use a lot of strength when performing the removal operation. The left hand holding the injection seat may be turned over due to the force during removal because the left hand is separated from the skin of the human body. In addition, during the needle removal process, the right hand removing the needle may rebound due to inertia, and the left hand holding the injection seat has not been removed at this time, so the right hand removing the needle may injure the left hand holding the injection seat due to the rebound. In order to ensure the needle-stick injury prevention effect, the needle-stick injury prevention layer is arranged on the surface of the left-hand thumb sleeve, the left-hand index finger sleeve, the left-hand middle finger sleeve, the right-hand thumb sleeve and the right-hand index finger sleeve. The needle-stick injury prevention layer is a layered structure formed by high-molecular-weight polyethylene fiber woven cloth, aramid woven cloth, glass fiber woven cloth and / or steel wire woven cloth, which is beneficial to the cutting resistance function, has large fiber strength and small weaving density, and is beneficial to the needle-stick prevention, so as to provide the fingers of the medical staff with a covered and full-angle needle-stick injury prevention protection.
[0025] In further embodiments, to avoid accidental movement of fingers during the operation of medical staff, the embodiments provided by the application are also provided with anti-skid pads 150, 250 outside the anti-puncture layer. In a possible embodiment, the anti-skid pads are distributed and arranged at the positions of the finger sleeve corresponding to the finger pads, and further, the anti-skid pads are also arranged and covered at the positions of the finger sleeve corresponding to the finger pads close to the finger pads. In another possible embodiment, the anti-skid pads are arranged and covered outside the anti-puncture layer at the positions of the finger sleeve corresponding to the finger segments, and the medical staff can have the anti-skid effect when the fingers are forced at any angle during the operation. Specifically, the anti-skid pads 150, 250 are made of silica gel soft pads, arranged on the surface of the anti-puncture layer, and fixedly connected with the anti-puncture layer, as shown in Figure 3 , the surface of the anti-skid pad is provided with anti-skid raised stripe lines, the anti-skid raised stripe lines are formed by the parallel distribution of raised pressing strips 151, the pressing strips are in a slightly curved and protruding state as a whole, and can be attached to the edge of the injection seat; the protective finger sleeve cooperates with the anti-skid raised to increase the friction force with the skin of the patient, and on the other hand, the pressing strips exert a pressing force on the upper part of the injection seat, which can greatly avoid the situation that the injection seat is deviated due to the force of pulling out.
[0026] Again referring to Figure 1 and Figure 2 , the left-hand protective finger sleeve 100 of the implantable central venous infusion port needle-stick prevention device provided by the embodiments of the application further comprises an elastic strip 160 connecting the left-hand thumb sleeve 110, the left-hand index finger sleeve 120 and the left-hand middle finger sleeve 130 into an integrated structure, and the elastic strip 160 is connected with the root ends of the left-hand thumb sleeve, the left-hand index finger sleeve and the left-hand middle finger sleeve in sequence to form an integrated left-hand protective finger sleeve. Similarly, the right-hand protective finger sleeve 200 further comprises an elastic strip 260 connecting the right-hand thumb sleeve 210 and the right-hand index finger sleeve 220 into an integrated structure, and the elastic strip 260 is connected with the root ends of the right-hand thumb sleeve and the right-hand index finger sleeve in sequence to form an integrated right-hand protective finger sleeve. The protective finger sleeve is connected into an integrated structure by the elastic strip, which can be adapted to medical staff with different hand shapes and palm sizes, and the medical staff can wear the protective finger sleeve on the corresponding fingers in sequence when using the protective finger sleeve. After the medical staff wear the protective finger sleeve, the elastic strip is located at the web space, which can adapt to different finger spacings and provide convenience for the use of medical staff. Specifically, the elastic strip is a multi-layer structure, which is composed of an inner silica gel layer and an outer protective layer.
[0027] The implantable central venous infusion port needle-stick prevention device provided by the embodiments of the application, when the medical staff use it to maintain the central venous infusion port, first clean the hands, select the protective finger sleeve of the appropriate size according to the hand shape, and then wear it on the left and right fingers to complete the preparation action, and then start working. After the use is completed, the protective finger sleeve should be disinfected and sterilized, and the protective finger sleeve should be classified and placed for the next use.
[0028] Based on the above scheme, it can be found that the anti-needle-stick device for implantable central venous infusion port provided by the application has simple design structure, convenient material selection and low cost; wearing and using operation is convenient, needle stick injury during maintenance and fixation of the infusion port can be effectively avoided, and the device is suitable for repeated use.
[0029] The above is only the preferred embodiment of the present application, and is not any form and substantial limitation of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the present application, a number of improvements and supplements can be made, and these improvements and supplements should be considered as the protection scope of the present application.
