Description

医用深部静脉套插针 The medical deep vein sleeve pin

本实新型涉及一种医疗器械,特别是一种医用深部静脉套插针,它可用于病人的颈内静脉,锁骨下静脉,股静脉的输注和监测,也有利于长期留管。 The present invention relates to a real medical instrument, in particular deep venous sets a medical pin, which can be used within a patient's jugular vein, femoral vein subclavian infusion and monitoring, but also favor long stay pipe.

目前国内外用于深静脉的穿刺用具有三种:(1)金属穿刺针。 Deep vein puncture is currently abroad for use with three: (1) a metal needle. 它是在穿刺成功后,通过穿刺针内孔置入导管,该方法因穿刺针太粗,而允许置入的导管较细,给治疗带来许多不便,目前已很少使用。 After it is successful puncture needle into the catheter through the puncture hole, the puncture needle because the process is too coarse, while allowing the catheter into smaller, a lot of inconvenience to the treatment, has been rarely used. (2)套管针,是由金属针芯和外套管构成,它是在穿刺成功后,将外套管送入血管,而且穿刺针和外套管同时刺入血管,创伤较大,此方法适用外周静脉,而对深部静脉穿刺就存在着使用不方便的缺点。 (2) a trocar needle is composed of a metal core and an outer sleeve, which after the puncture is successful, the outer sleeve into the vessel, and the needle and pierce the vessel while the outer sleeve, trauma, this method is applicable to an outer periphery veins, and deep vein puncture on the existence of inconvenient shortcomings. (3)导丝法穿刺用具,该方法的穿刺针往往较粗大,在对病人反复探插时容易造成意外或并发症。 (3) Method guidewire puncture device, the puncture needle which is often coarse, easily lead to accidents or complications when the patient is repeatedly inserted probe. 又因置入导管的扩张度有限,而且导管置入的深度无标记,在临床使用中,尤其是对于婴幼儿有诸多不便。 Because of the limited dilation catheter placement, catheter placement and depth without marking, in clinical use, especially for infants and young children there is a lot of inconvenience.

本实用新型的目的是针对以上的不足而研制的一种医用深部静脉套插针,它是在导丝法穿刺用具的基础上增设了扩张管,以扩大置入导管的直径。 The object of the present invention is directed to more medical insufficient developed a deep vein pin sets, which is based on the addition of the expanded tubular puncturing tool methods on the guidewire to enlarge the diameter of the catheter placement. 它是将扩张管装在外套管内,沿导丝置入血管,最大限度地扩大导管直径,以利于输液与测压。 It is the expansion of the sleeve within the outer tubes, into the blood vessel along the guide wire, to maximize the diameter of the catheter to facilitate infusion and pressure measurement. 外套管上有刻度。 A scale on the outer sleeve. 可根据需要取留长短,也有利于静脉输注和监测,便于长期留管,此方法提高了穿刺的安全性。 May need to take depending on how long to stay, but also conducive to intravenous infusions and monitoring for long term stay in control, this method improves the safety of puncture.

本实用新型是这样实现的:医用深部静脉套插针,包括穿刺针1、弹簧导丝2,外套管4和扩张管3,其中,弹簧导丝2穿装在穿刺针1内,外套管4内装的扩张管3套装在弹簧导丝2上。 The present invention is achieved: the medical deep vein sleeve pin, comprising a puncture needle 1, the spring wire 2, the outer sleeve 4 and the expanded pipe 3, wherein the spring wire 2 reeved in the puncture needle 1, the overtube 4 built dilation tube spring 3 is fitted over the guidewire 2.

本实用新型也可以是这样实现的:外套管4上有刻度5。 The present invention may be implemented as follows: the outer casing 5 on a scale 4.

本实用新型的积极效果是:1、本实用新型的穿刺针较细,它可以减小组织损伤,降低穿刺的危险性。 The positive effect of the present invention is: 1, the puncture needle of the present invention thin, it is possible to reduce tissue damage, reduce the risk of puncture.

2、本实用新型对血管较细的婴幼儿和穿刺困难的病人,穿刺置管成功率高。 2, the present invention is to thin the blood vessel puncture in infants and difficult patients, catheterization success rate.

3、深部静脉周围往往伴随着大动脉或重要脏器,本实用新型的结构合理,可靠,可减少误伤周围组织器管,以减少并发症。 3, peripheral deep vein or aorta often accompanied by vital organs, the present invention is reasonable and reliable structure, can be reduced harming surrounding tissue tube, in order to reduce complications.

4、由于本实用新型扩张管的作用,不仅扩大外套管直径有利于快速输液和静脉压监测,而且还避免了穿刺针眼周围渗血。 4, due to the effect of the present invention to expand the tube, not only to expand the diameter of the outer tube facilitates rapid infusion and venous pressure monitoring, but also to avoid bleeding around the eye of a needle puncture.

5、本实用新型的外套管上有刻度,便于了解置管的深浅。 5, the scale on the outer sleeve of the present invention, to facilitate understanding of the depth of the catheter.

6、本实用新型经临床应用205例,成功率100%,无并发症发生,既安全又方便。 6, the clinical application of the present invention, 205 cases, 100% success rate, no complications, safe and convenient.
