Abstract

The utility model relates to a suction bag which comprises a suction bag main body. The suction bag main body is arranged in a drainage barrel. A bag opening of the suction bag main body is connected with a suction bag cover which is provided with a drainage connecting pipe joint and a negative pressure machine connecting pipe joint respectively. The suction bag is characterized in that the lower end of the negative pressure machine connecting pipe joint is connected with a hollow pipe. A low-density ball is arranged in an inner cavity of the hollow pipe. The density of the low-density ball is lower than that of the blood, tissue fluid of human body or normal saline. The low-density ball is a silicon rubber ball. A gap is reserved between the upper end of the low-density ball and the lower end of the negative pressure machine connecting pipe joint. The suction bag retains the advantages of a traditional suction bag and with the aid of an anti-suck-back device arranged at the position of a negative pressure machine connecting opening, the problem of suck-back caused by failing to replace the suction bag timely because of a large amount of suction is resolved.

Description

A kind of attraction bag
Technical field
This utility model relates to a kind of attraction bag, and especially a kind of attraction bag that is used on the Negative pressure machine belongs to medical instruments field.
Background technology
The vacuum suction technology is used extremely extensive at surgical field, usually need a large amount of physiological saline solution flushing abdominal cavity, thoracic cavity and internal organs etc. in the operation process, vacuum suction is convenient to remove fragment of tissue, blood, pus and the tumor cell etc. that comes off, so both surgical field of view clearly, can clean internal organs again, the chance of reduce inflammation reaction and reduction bacterial infection.Negative pressure suction device also is a kind of medical care expenses collection simultaneously, is the indispensable apparatus of operating room, surgery, department of obstetrics and gynecology and each clinical department.The source that just forms at present negative pressure can be divided into two kinds of forms of Negative pressure machine and central negative pressure system, all needs supporting drain bucket and the drainage bag that is attached thereto.When traffic attraction is little, above-mentioned two covering devices can be good at solving the attraction problem, but when running into rupture of spleen bleeding of abdominal cavity, a large amount of puss and a large amount of flushing liquor, drainage bag is easy to be filled, communicate with drainage bag owing to Negative pressure machine this moment, the expense liquid that is attracted in the drainage bag will be sucked in Negative pressure machine or the central negative pressure system, causes apparatus contamination and damage.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of attraction bag that can prevent suck-back is provided.
The technical scheme that provides according to this utility model, described attraction bag comprises attracting the bag main body that described attraction bag main body is arranged in the drain bucket, attract the bag mouth of bag main body to be connected, cover at drainage bag and be respectively arranged with drain connection tube joint and Negative pressure machine connection tube joint with the drain pkt. flap; Feature is: be connected with the hollow out pipe of hollow in the lower end of described Negative pressure machine connection tube joint, be provided with the low-density ball in the inner chamber of hollow out pipe.
The density of described low-density ball is less than blood, tissue liquid or normal saline.
Described low-density ball is a silicone rubber ball.
There is the space between the lower end of the upper end of described low-density ball and Negative pressure machine connection tube joint.
The diameter of described hollow out pipe and low-density ball is all greater than the diameter of Negative pressure machine connection tube joint.
This utility model has not only kept traditional advantage that attracts bag, and by effectively solving by means of the anti-suck device that is located at the Negative pressure machine seam because of attracting in time not change the worry that drainage bag causes suck-back in a large number.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As Fig. 1 ~ shown in Figure 2: attract bag to comprise drain bucket 1, drain pkt. flap 2, attract a bag main body 3, drain connection tube joint 4, Negative pressure machine connection tube joint 5, low-density ball 6, hollow out pipe 7 etc.
This utility model comprises an attraction bag main body 3, and a described attraction bag main body 3 is arranged in the drain bucket 1, attracts the bag mouth of bag main body 3 to be connected with drain pkt. flap 2; Be respectively arranged with drain connection tube joint 4 and Negative pressure machine connection tube joint 5 on drain pkt. flap 2, described drain connection tube joint 4 is used for being connected with the drain connection tube, and described Negative pressure machine connection tube joint 5 is used for being connected with the connection tube of Negative pressure machine; Be connected with the hollow out pipe 7 of hollow in the lower end of Negative pressure machine connection tube joint 5, in the inner chamber of hollow out pipe 7, be provided with low-density ball 6, the hollow out pipe 7 of hollow and the diameter of low-density ball 6 are greater than the diameter of Negative pressure machine connection tube joint 5, the density of described low-density ball 6 is less than blood, tissue liquid or normal saline, is 0.8 as the density of silicone rubber ball;
There is the space between the lower end of the upper end of described low-density ball 6 and Negative pressure machine connection tube joint 5.
Operation principle of the present utility model: during work, drain connection tube on the drain connection tube joint 4 on the drain pkt. flap 2 feeds human abdominal cavity or thoracic cavity, connection tube on the Negative pressure machine connection tube joint 5 is connected with Negative pressure machine, Negative pressure machine produces negative pressure, human abdominal cavity or intrathoracic fragment of tissue, blood or pus etc. is sucked attract bag main body 3 inside; When waste liquid did not reach low-density ball 6, low-density ball 6 was positioned at cylindrical bottom, and had the space between the lower end of Negative pressure machine connection tube joint 5, and negative pressure passes to drain connection tube front end along the hollow out place of the hollow out pipe 7 of hollow; When the waste liquid fluid level reaches low-density ball 6, under buoyancy function, low-density ball 6 is owing to density is moved upward less than blood, tissue liquid or normal saline, finally blocked the lower port of Negative pressure machine connection tube joint 5, stopped vacuum suction, effective isolation contacting of central negative pressure system or Negative pressure machine and attraction bag main body 3, prevented to attract the waste liquid suck-backs in the bag main body 3 to advance central negative pressure system or Negative pressure machine, avoid waste liquid that it is produced and damage.
