CN201453810U - Balloon with catheter pushing sleeve - Google Patents

Abstract

The utility model relates to a balloon with a catheter pushing sleeve. The balloon with a catheter pushing sleeve comprises a balloon body, a balloon catheter and a balloon handle, wherein two ends of the balloon catheter are respectively connected to the balloon body and the balloon handle, the balloon catheter is sleeved with an elastic catheter pushing sleeve detachably connected with the balloon handle, the internal diameter of the tail end of the catheter pushing sleeve approaching the balloon handle matches with the balloon handle, and the outer surface of the catheter pushing sleeve is provided with grooves or projections used for increasing friction force. The catheter pushing sleeve arranged on the balloon catheter increases push force conducting efficiency of the balloon catheter, and transmits push force to the balloon body more effectively, thereby being favorable for fast operation of the balloon catheter, increasing integral throughout capacity of the balloon and increasing working efficiency.

Description

Have the sacculus that conduit pushes cover

Technical field

This utility model is specifically related to a kind of sacculus that conduit pushes cover that has.

Technical background

After the nineties in 20th century, Wicresoft's interventional therapy angiopathy [minimally invasive therapy] technology begins to have obtained widely to use, and has been acknowledged as one of the most effective means of treatment cardiovascular and cerebrovascular disease.At different vascular lesions and requirement, research worker and doctor develop the novel vascular stent of superior performance jointly, and have obtained the achievement that attracts people's attention.

Along with the innovation and the development of minimally invasive medical technology, support expansion completely is beneficial to the incidence rate that prevents restenosis, reduces target lesion reconstruction and stent thrombosis.Studies show that support not exclusively expansion is the independent hazard factor of postoperative generation stent thrombosis.Because expansion can obviously increase the minimum support area of MSA[Minimum Stent Area behind the non-compliant balloon support inner high voltage] and MSD[Minimum Stent Diameter support minimum diameter], therefore the back expansion can increase DES[Drug Eluting Stent bracket for eluting medicament greatly] the desirable success rate of implanting.Therefore, the scope of application of sacculus more and more widely, usage quantity grows with each passing day.In the middle of operation, the doctor is undertaken by transporting of the foley's tube that is connected with sacculus pushing or return when removing sacculus normally, but, have the following problem that influences the foley's tube smooth delivery of power at present: one, the foley's tube external diameter is thinner, usually between 2.0～2.55F (F intervention field abroad is commonly used to represent the usage of conduit diameter, and conversion relation is 1mm=3F); Two, the doctor wears sterile glove, and glove are stained with medicinal liquid, disinfectant solution or blood stains etc., and course of conveying skids easily, normally the carrying out of influence operation.

In order to improve the convenience that the doctor operates foley's tube, foley's tube is carried out some new designs and improvement is necessary.

The utility model content

The purpose of this utility model is to improve the operability of foley's tube, provides a kind of doctor of being convenient to carry out the sacculus that has conduit propelling movement cover that sacculus pushes.

A kind of conduit that has pushes the sacculus that overlaps, comprise sacculus body, foley's tube and sacculus handle, the two ends of described foley's tube connect sacculus body and sacculus handle respectively, be arranged with one on the described foley's tube and push cover with the dismantled and assembled silicon catheter that is connected of sacculus handle, this conduit pushes cover and mates with the sacculus handle near the terminal internal diameter of sacculus handle; The outer surface that described conduit pushes cover is provided with to increasing the groove or the column-shaped projection of frictional force.

The shaft section that described conduit pushes cover is trapezoidal.

The opening of the end of described internal diameter is contraction shape, helps the sacculus handle that better is locked.

The utlity model has following advantage:

(1) this utility model is provided with a conduit and pushes cover providing on the foley's tube, improve the propelling movement power conduction efficiency of foley's tube, make propelling movement power more effectively be passed to the sacculus body, help the operation readiness of foley's tube, increase the whole handling capacity of sacculus, increase work efficiency.

(2) this utility model selects for use elastic material and outer surface to have the conduit propelling movement cover of big frictional force, can help the foley's tube of holding with a firm grip, is convenient to carry.

(3) end of the internal diameter of conduit propelling movement cover of the present utility model adopts the design of contraction shape to be set in above the sacculus handle in the time need not pushing sacculus, does not hinder doctor's operate as normal.

(4) this utility model is rational in infrastructure, humanization designing, for calcification, tortuous, become angle, challenge pathological changes such as extremely narrow that the high suitability is arranged, serve doctor and patient effectively.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the cross-sectional view that this utility model conduit pushes cover.

Specific embodiments

As shown in Figure 1, this utility model provides a kind of sacculus that conduit pushes cover that has, comprise sacculus body 1, foley's tube 2 and sacculus handle 3, the two ends of described foley's tube 2 connect sacculus body 1 and sacculus handle 3 respectively, be arranged with one on the described foley's tube 2 and push cover 4 with the dismantled and assembled medical silastic vessels that are connected of sacculus handle 3, it is 25.4mm～30.0mm that described conduit pushes condom height degree, holds to be fit to pinching of thumb, forefinger and middle finger.

As shown in Figure 2, the outer surface that this conduit pushes cover 4 is provided with to increasing the column-shaped projection point 5 of frictional force, prevents to skid when firmly pushing, and shaft section is trapezoidal.

Leading portion internal diameter 6 and foley's tube 2 couplings are 3～4F, and terminal internal diameter 7 and sacculus handle 3 couplings near 1/4 section of the internal diameter of sacculus handle are 15F, and the opening of the end of described internal diameter is and shrinks shape, and port is 14F.The naturalness conduit propelling movement cover 4 of not executing axial force at finger can be free to slide along foley's tube 2, and the time spent can not be placed in foley's tube handle 3 places by the end of internal diameter.

Claims (3)

1. one kind has the sacculus that conduit pushes cover, comprise sacculus body, foley's tube and sacculus handle, the two ends of described foley's tube connect sacculus body and sacculus handle respectively, it is characterized in that, be arranged with one on the described foley's tube and push cover with the dismantled and assembled silicon catheter that is connected of sacculus handle, this conduit pushes cover and mates with the sacculus handle near the terminal internal diameter of sacculus handle; The outer surface that described conduit pushes cover is provided with to increasing the groove or the column-shaped projection of frictional force.
