Abstract

The utility model belongs to a three-cavity pipe pulling device used for pulling bleeding points oppressing esophagus and stomach fundic veins, which comprises a supporting rod 5, a fixing frame fixed at the lower end of the supporting rod 5, and a rotary wheel 4 arranged at the upper end of the supporting rod 5. A pulling cable 3 of the utility model passes by the rotary wheel 4, the front end of the pulling cable 3 is provided with a sleeve hook 1 connected with a three-cavity pipe 2, and the back end is tied with a pulling rod 6. One or more matching blocks 7 are arranged on the pulling rod 6. The utility model has the advantages of accurate positioning, stable pulling force, reasonable structure and convenient operation.

Description

Three lumen tractor

This utility model belongs to a kind of medical apparatus and instruments.Specifically break when hemorrhage, be used for tractive to fix three lumens, compressing petechia hemostatic device at the esophagus fundus ventricularis varication due to the portal hypertension.

For esophagus, varices of fundus of stomach due to the portal hypertension hemorrhage patient of breaking, during treatment, at first to stop blooding, the hemostatic method is a lot, and the most frequently used is three lumens that insert its lower end band air bag by the nostril esophagus in stomach.After three lumens are inserted in the stomach, make the airbag aeration of its lower end, and then be pulled outwardly three lumens, make it the hemorrhage place of balloon tamponade and stop blooding.Three ends of its three lumen are fixed with a fixture, to keep the compressing power of air bag to the petechia.By retrieval, the fixture of this three lumens mainly contains following several: (1) Chinese patent ZL93227402 number, title " traction apparatus of sengstaken-blakemore tube ", it is a kind of hat type skeleton, both sides are fixed under the chin with the fiber strap, one end of support is connected with the hat type skeleton by bolt, and sengstaken-blakemore tube is connected to form through a spring tension meter and tension slide block.Strain gauge of this device and three lumens are difficult for being connected firmly, and three lumens drawn the back yielding, retractility is big, thereby pulling force do not weigh fixed, inaccurate.Install cumbersome.Fiber strap bundle also causes patient's discomfort easily, and influences perspire in head, and this apparatus structure is more complicated also.(2) Chinese patent ZL92219190, name is called " three lumen fixed mounts ", and it is by two clamping plate and fixed connection apparatus are formed up and down.Though this device is simple in structure, its traction force is inaccurate, just estimated value.Clamping plate are easily hindered three lumens.Three lumens are easily oppressed the wing of nose, and clamping plate compressing upper lip causes patient's misery.Fixing not firm yet, stomach tube is also not smooth.(3) Chinese patent ZL91201050, name is called " two capsules, three lumen fixed mounts ", and it is made up of girder, air gauge, four-way cock and two supports.This device has the support effect to three lumens, and three lumens do not oppress the wing of nose, and it is movable not limit head, but its no traction action, and its two supports easily cause patient's misery.

The purpose of this utility model be to provide a kind of rational in infrastructure, pull strength is accurate and effective, the pulling device that hemostasis by compression is effective.

This utility model is to realize like this, it comprises a support bar, the bottom of this support bar is provided with one at least and is fixedly mounted on a upper holder, a runner is installed in the upper end of this bracing frame, a stay cord is walked around this runner, the front end of stay cord has a cover hook that is connected with three lumens, and there is a stayed pole in the rear end system of stay cord, one or more balancing weight is housed on this stayed pole constitutes.

Because what this tractor adopted is pulley mechanism, it can make the nostril direction of direction of draw when the people lies on the back carry out, and makes distracted position more reasonable, and is also smaller to the damage of human body.Its pull strength solves with one or more special-purpose balancing weight, and pull strength is not subjected to the influence of factors such as stay cord, three lumen distortion, can keep the steady pressure to the petechia, prevents the hemorrhage of stomach, esophagus effectively, quickens the healing of petechia.This apparatus structure is simple, easy to use, traction force and lead are accurate, can extensively use clinically.

Accompanying drawing is a structure principle chart of the present utility model.

Below in conjunction with accompanying drawing this utility model is described in detail.

Support bar 5 of the present utility model is bracing frames, its lower end has a fixed mount 8 that can be fixed on the bed 10 at least, its upper end is equipped with a runner 4, its stay cord 3 is walked around runner 4, the front end of stay cord 3 has a cover hook 1 that is connected with three lumens 2, there is a stayed pole 6 in the rear end system of stay cord 3, one or more balancing weight 7 is installed on the stayed pole 6 constitutes.

Balancing weight 7 can be sleeved on the stayed pole 6, also can hang on the stayed pole 6.Balancing weight 7 is made of the metal of a plurality of Different Weight or nonmetal, and their weight can be 0.1,0.2,0.3,0.4,0.5,0.6Kg or the like.They can use separately, also can be used.Using more clinically is the weight of 0.3-0.5Kg.

For the ease of adjusting the height of support bar 5, support bar 5 is preferably made expansion link.The support bar 5 of making flexible rod-type can be made of through set bolt or hollow nut cover in and a trocar sheath.

In order to strengthen the stability of support bar 5, also be provided with a following fixation clamp that matches with fixed mount 89 in the lower end of support bar 5 and constitute.
