Abstract

The utility model discloses a venous catheter presss from both sides, including first splint and second splint, the end of first splint is articulated with the end of second splint, the front end of first splint passes through the detachable connection of block structure with the front end of second splint, vacuole formation structure when first splint and second splint closed type has improved the condition that the pipe easily drops from putting into the mouth, has the rubber layer parcel more soft, can reduce skin wearing and tearing risk, and independent packing uses more conveniently, can change at any time, can wide application in have the administrative or technical offices of keeping somewhere central venous catheter patient.

Description

Venous catheter clamp

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to venous catheter presss from both sides.

Background

A central venous catheter (CVC tube for short) belongs to one of intravascular tubes, is placed in a large vein and is used for hemodialysis or other blood purification therapies, and the like, and is provided with a catheter clamp.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

In order to overcome prior art not enough, provide a venous catheter clamp now, can improve the condition that the pipe drops from pipe clamp department, the outside includes that the rubber material is more soft, can reduce skin abrasion risk.

(II) technical scheme

The utility model discloses a following technical scheme realizes: the utility model provides a venous catheter presss from both sides, including first splint and second splint, the end of first splint is articulated with the end of second splint, the front end of first splint passes through the detachable connection of block structure with the front end of second splint, vacuole formation structure during first splint and second splint closed type.

Furthermore, the clamping structure comprises a protrusion at the front end of the first clamping plate and a notch at the front end of the second clamping plate, and the protrusion and the notch are detachably clamped and connected.

Further, the clearance upper end of cavity structure is oval lower extreme for the toper and from last clearance down is more and more littleer, oval clearance is greater than the ductus venosus diameter.

Furthermore, the outer sides of the first clamping plate and the second clamping plate are wrapped with rubber protective layers.

(III) advantageous effects

Compared with the prior art, the utility model, following beneficial effect has:

the utility model provides a venous catheter presss from both sides has improved the pipe and has easily followed the condition of putting into mouthful department and coming off, has rubber layer parcel more soft, can reduce skin wearing and tearing risk, and independent packing is used more conveniently, can change at any time, can wide application in there being the administrative or technical offices that keep somewhere central venous catheter patient.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

An intravenous catheter clamp as shown in fig. 1-2 comprises a first clamping plate 1 and a second clamping plate 2, wherein the tail end of the first clamping plate 1 is hinged with the tail end of the second clamping plate 2, the front end of the first clamping plate 1 is detachably connected with the front end of the second clamping plate 2 through a clamping structure 3, and a cavity structure 4 is formed when the first clamping plate 1 and the second clamping plate 2 are closed.

Wherein, block structure 3 includes the arch 11 of 1 front end department of first splint and the notch 21 of 2 front end departments of second splint, protruding 11 is connected with the detachable block of notch 21, and the clearance upper end of cavity structure 4 is oval lower extreme for the toper and follow and down the clearance more and less little, oval clearance is greater than the venous catheter diameter, and first splint 1 all wraps up with the outside of second splint 2 and is provided with the rubber protection layer.

The utility model provides a venous catheter presss from both sides, adopt independent packing, it is when specifically using, arrange central venous catheter in between first splint 1 and second splint 2, rotatory closed first splint 1 and second splint 2, make central venous catheter arrange in the oval hole on cavity structure 4, it is fixed with the block of notch 21 on the second splint through protruding 11 on first splint 1, first splint 1 and second splint 2 are closed, when needs use, go into central venous catheter from cavity structure 4 down the removal card in and go into to the notch in below toper clearance, central venous catheter is in by the state of being compressed tightly and can prevents the blood backward flow effectively this moment, when need not using, push back central venous catheter to oval clearance department, central venous catheter is in the diastolic state this moment, the blood circulation is smooth and easy, the rubber protection layer in the first splint 1 and the second splint 2 outside is softer, can reduce skin abrasion risk.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solutions of the present invention should fall within the protection scope of the present invention, and the technical contents claimed in the present invention have been fully recorded in the claims.
