Description
技术领域Technical Field
本实用新型涉及穿刺固定器技术领域,具体为一种可调节大小的输液港穿刺固定器。The utility model relates to the technical field of puncture fixators, in particular to an infusion port puncture fixator with adjustable size.
背景技术Background Art
输液港是一种可植入皮下长期留置在体内的静脉输液装置,主要由供穿刺的注射座和静脉导管系统组成,可用于输注各种药物、补液、营养支持治疗、输血、血样采集等,输液港由导管、导管锁和注射座组成,其中注射座由穿刺隔、侧壁和基底、储液槽及缝合孔构成,在利用输液港进行输液时需使用无损伤针进行穿刺,进行穿刺时在病人体表可触摸到一圆形凸起,将无损伤针经皮垂直穿刺到注射座的储液槽即可,无损伤针的应用时限为一周,因此长期治疗的患者要每周更换一次无损伤针。An infusion port is an intravenous infusion device that can be implanted subcutaneously and left in the body for a long time. It is mainly composed of an injection seat for puncture and an intravenous catheter system. It can be used for infusion of various drugs, fluid replacement, nutritional support therapy, blood transfusion, blood sample collection, etc. The infusion port is composed of a catheter, a catheter lock and an injection seat, wherein the injection seat is composed of a puncture septum, side walls and base, a fluid reservoir and a suture hole. When using the infusion port for infusion, a non-destructive needle must be used for puncture. During puncture, a round protrusion can be felt on the patient's body surface. The non-destructive needle can be punctured vertically through the skin into the fluid reservoir of the injection seat. The application period of the non-destructive needle is one week, so patients undergoing long-term treatment should replace the non-destructive needle once a week.
目前临床留置无损伤针均为手法三点固定皮下注射座再进行穿刺,但注射座在皮下容易滑动难以固定,由此对医护人员技术要求较高,难以保证穿刺的成功率,给患者带来一定的穿刺痛苦。Currently, clinical indwelling non-destructive needles are all performed by manual three-point fixation of the subcutaneous injection seat before puncture. However, the injection seat is easy to slide under the skin and difficult to fix. This places high technical requirements on medical staff, makes it difficult to guarantee the success rate of puncture, and causes certain puncture pain to patients.
因此,提出一种可调节大小的输液港穿刺固定器。Therefore, an infusion port puncture fixator with adjustable size is proposed.

The utility model provides a technical solution: an adjustable size infusion port puncture fixator, including a limit ring 1, a pressing handle 2 is installed on both sides of the limit ring 1, a plug-in column 3 is installed at one end of the limit ring 1, and a first plug-in hole 4, a second plug-in hole 5 and a third plug-in hole 6 are opened at the other end of the limit ring 1. The plug-in column 3 is plugged into the first plug-in hole 4, the second plug-in hole 5 and the third plug-in hole 6. A friction pad is installed on the plug-in column 3, and the friction pad contacts the inner wall of the first plug-in hole 4, the second plug-in hole 5 and the third plug-in hole 6. When the plug-in column 3 is plugged into the first plug-in hole 4, the friction pad is in contact with the inner wall of the first plug-in hole 4, the second plug-in hole 5 and the third plug-in hole 6, the plug-in column 3 is plugged into the first plug-in hole 4. The inner diameter of the limiting ring 1 is 2.0 cm, the inner diameter of the limiting ring 1 is 2.2 cm when the plug-in column 3 is plugged into the second plug-in hole 5, and the inner diameter of the limiting ring 1 is 2.4 cm when the plug-in column 3 is plugged into the third plug-in hole 6. When puncturing the subcutaneous injection seat, the plug-in column 3 can be plugged into the corresponding plug-in hole according to the size of the injection seat, and then the limiting ring 1 is pressed around the injection seat, and the pressing handle 2 is pressed by hand to make the limiting ring 1 close to the patient's skin, so that the injection seat can be fixed in the limiting ring 1, thereby preventing it from sliding under the skin during puncture, which brings certain convenience to the puncture operation of medical staff. The success rate of puncture is improved. At the same time, the device is designed with three plug-in holes. When the plug-in column 3 is plugged into the first plug-in hole 4, the inner diameter of the limit ring 1 is 2.0 cm, when the plug-in column 3 is plugged into the second plug-in hole 5, the inner diameter of the limit ring 1 is 2.2 cm, and when the plug-in column 3 is plugged into the third plug-in hole 6, the inner diameter of the limit ring 1 is 2.4 cm. Therefore, the inner diameter of the limit ring 1 can be adjusted according to the size of the injection seat, so that it has a better effect of fixing the injection seat. At the same time, it can be repeatedly disinfected and used, thereby improving its applicability and saving resources. After the puncture is completed, the plug-in column 3 is pulled out from the plug-in hole. The limiting ring 1 can be taken out from the side as a whole to avoid the situation where it is blocked by the puncture needle and cannot be taken out, which is convenient and quick; a friction pad is installed on the plug-in column 3, and the friction pad contacts the inner walls of the first plug-in hole 4, the second plug-in hole 5 and the third plug-in hole 6. The friction pad is arranged on the plug-in column 3, which can prevent the plug-in column 3 from slipping out of the plug-in hole when the limiting ring 1 is used, causing the two ends of the limiting ring 1 to separate and lose the fixing effect, thereby improving the stability of the limiting ring 1 when used; the limiting ring 1 is made of tough material, so it can be bent, which is convenient for plugging the plug-in column 3 into different plug-in holes.
工作原理为：在对注射座进行穿刺时,可根据注射座的尺寸,将插接柱3插接在对应的插接孔内,之后将限位环1按压在注射座的周围,并用手按压住按压手柄2使得限位环1贴紧患者的皮肤,即可将注射座固定在限位环1内,由此可在穿刺时防止其在皮下滑动,为医护人员的穿刺操作带来一定的便利,提高穿刺的成功率,在穿刺完成后,将插接柱3从插接孔内拔出,即可将限位环1整体从侧面取出,避免出现其受到穿刺针的阻挡而取不出来的情况,方便快捷。The working principle is as follows: when puncturing the injection seat, the plug-in column 3 can be plugged into the corresponding plug-in hole according to the size of the injection seat, and then the limiting ring 1 is pressed around the injection seat, and the pressing handle 2 is pressed by hand to make the limiting ring 1 close to the patient's skin, so that the injection seat can be fixed in the limiting ring 1, thereby preventing it from sliding under the skin during puncture, bringing certain convenience to the puncture operation of medical staff and improving the success rate of puncture. After the puncture is completed, the plug-in column 3 is pulled out of the plug-in hole, and the limiting ring 1 can be taken out from the side as a whole to avoid the situation where it is blocked by the puncture needle and cannot be taken out, which is convenient and quick.
尽管已经示出和描述了本实用新型的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本实用新型的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本实用新型的范围由所附权利要求及其等同物限定。Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
