Description

Hemodialysis pipe connector

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to hemodialysis pipe joint.

Background

Hemodialysis is the main treatment means of uremia patient, need establish the blood passageway between dialysis machine and human body during hemodialysis, generally adopts direct intervention deep vein blood vessel to establish the blood passageway clinically, and the hemodialysis pipe that direct intervention vein blood vessel used then need not to puncture repeatedly, only needs once to puncture to accomplish intervene and puts the pipe, when carrying out hemodialysis in the future, only needs to connect blood way pipe and dialysis machine with the dialysis pipe and can go on. Present dialysis catheter and blood way pipe connect through connecing the pipe joint soon to be connected, connect soon to connect more can reduce the risk of leaking blood and air admission and use more and more extensively than the joint, need part dialysis catheter and blood way pipe after hemodialysis is accomplished, because the temperature of intraductal blood is usually than outside of tubes ambient temperature high, under the thermal expansion effect, male joint and female joint laminating are tight, and the current handheld portion of joint is the round slip face usually, some are equipped with anti-skidding line, but the totality power of gripping is little, the pipe joint is difficult to unload soon, especially when the inside and outside difference in temperature exceeds 10 degrees, often need look for other instruments to assist and lift down, it is very inconvenient, and the operation is troublesome.

Therefore, the key point for solving the problem is to research and develop the hemodialysis catheter connector which is simple in structure, convenient to process and easy to unscrew.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a hemodialysis pipe connector.

The utility model aims at realizing like this, including male joint, the female joint who matches with the male joint, the handheld portion of male joint outer wall, the handheld portion of female joint outer wall all are provided with the twist grip that is used for the increase to revolve to twist the arm of force.

The utility model discloses following technological effect has:

1. the outer walls of the handheld parts of the male and female connectors are provided with the twisting handles, so that the force arm during twisting is increased, the twisting is convenient to disassemble, the slipping is avoided, and the twisting is convenient;

2. the width of the twist handle is half of the outer diameter of the hand-held part, so that the operation stress is ensured, and the waste and the influence on the operation caused by overlong increased cost are avoided;

3. and an integrated structure is adopted, so that the processing and the production are convenient.

Detailed Description

The following description of the present invention is provided with reference to the accompanying drawings, which are not intended to limit the present invention in any way, and any alterations or replacements made based on the teachings of the present invention are all within the protection scope of the present invention.

As shown in the attached drawings 1-6, the utility model discloses a male joint 1, with the female joint 2 that the male joint matches, the handheld portion of male joint outer wall, the handheld portion of female joint outer wall all are provided with and are used for increasing the twist handle 3 of twisting the arm of force soon.

The twist handle 3 and the joint hand-held part are integrally formed.

Twist grip 3 and the flat face sets up along the joint center pin axial for flat twist grip and flat shape, and the flat shape does not occupy the place, is convenient for hold between the fingers and takes, and the stress surface is big and perpendicular with moment.

The twist handles 3 are arranged on the outer wall of the joint at equal intervals along the circumference.

The number of the twist handles on each joint is 1.

The number of the twist handles on each joint is 2.

The number of the twist handles on each joint is 3.

The number of the twist handles on each joint is 4

The length of the flat twist grip 3 is not greater than the length of the joint hand-held part.

The length of the flat twist handle 3 is the same as that of the joint hand-held part.

The width of the flat twisting handle 3 is one third to two thirds of the outer diameter of the joint, the too short force arm is small, the pinching is inconvenient, and the operation is influenced by too long waste materials.

The width of the flat twist grip 3 is one half of the outer diameter of the joint.

The twist handle 3 is detachably connected with the joint handheld part, the twist handle is separated from the joint at ordinary times, and the joint is basically the same as the existing joint and cannot obstruct and influence the operation.

The detachable connection is a clamping groove connection, one end of the twisting handle is provided with a clamp, and the tail end of the handheld portion of the joint is provided with a clamping groove 5 matched with the clamp.

The other end of the twisting handle is connected with the joint through a soft rope 6, the length of the soft rope does not influence the twisting handle to be clamped into the joint clamping groove, the twisting handle is connected to the joint through the soft rope, the twisting handle is not easy to lose, and the operation is convenient.

The soft rope is a soft plastic belt.

The utility model discloses theory of operation and working process: according to the principle that the torque force is increased when the acting force is the same and the moment arm is increased. When screwing, one hand is used for pinching and holding the male connector, the other hand is used for pinching and holding the female connector, the thumb or other fingers are used for pressing the twisting handle, and the two hands are used for screwing forcefully in the opposite direction, so that the male connector and the female connector are screwed together or unscrewed. When the detachable handle is used, the handle clip end is placed into the clamping groove at the tail end of the handheld portion of the connector, the male connector is held between the fingers of one hand, the female connector is held between the fingers of the other hand, the twisting handle is pressed by the thumb or other fingers, and the male connector and the female connector are screwed and disassembled in a reverse mode by two hands.
