Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-4, the utility model discloses thorax closed drainage device, including drainage bottle 1 and fluid infusion bottle 2, form the bottle chamber in drainage bottle 1's the bottle, drainage bottle 1 is made by the stereoplasm material, for example glass or plastics material, the plastics that are transparent material best. The drainage bottle 1 is provided with an exhaust port 11 for communicating the bottle cavity and the outside of the bottle body, and the exhaust port 11 is used for balancing the air pressure in the bottle cavity. In order to prevent dust and the like from entering the bottle cavity, a blocking cover is arranged at the exhaust port 11, and a ventilation structure is arranged on the blocking cover. The exhaust port 11 may further be provided with a joint, the joint may be used for connecting a negative pressure device to realize negative pressure drainage, and the joint is preferably detachably connected with a stopper cover so as to be convenient for detaching the stopper cover to connect the negative pressure device. The bottle body is also provided with a liquid guide pipe 12, the upper end of the liquid guide pipe 12 is positioned outside the bottle body, and the lower end of the liquid guide pipe 12 is positioned at the bottom of the bottle cavity. The upper end of the catheter 12 is adapted to be connected to a drainage tube for venting gas or collecting fluids within the thoracic cavity. The lower end of the liquid guide pipe 12 is positioned in the drainage bottle 1 and is sealed by liquid. The top of the drainage bottle 1 is provided with a hook 3 and/or a lifting rope 4. The number of the hooks 3 is preferably 2-4 to keep balance. The two lifting ropes 4 are preferably arranged in a cross way, so that the drainage bottle 1 can be conveniently lifted by a patient when the patient leaves the bed or is assisted by family members.

The liquid replenishing bottle 2 is filled with sealing liquid, for example, the sealing liquid is physiological saline or other sterile solution, the liquid replenishing bottle 2 is communicated with the drainage bottle 1 through a liquid replenishing pipe 21, and the liquid replenishing pipe 21 is provided with a first switch 22. The first switch 22 can be a knob switch or a clip. In order to make the fluid infusion bottle 2 and the drainage bottle 1 form a whole and avoid the fluid infusion bottle 2 from scattering, a matched buckle structure is arranged between the fluid infusion bottle 2 and the drainage bottle 1. For example, a concave-convex type clamping hook and a buckling hole are arranged between the bottom of the liquid replenishing bottle 2 and the drainage bottle 1, and the clamping hook and the buckling hole are mutually matched. The outer side of the liquid replenishing bottle 2 can be provided with volume scales, so that the amount of sealing liquid in the liquid replenishing bottle 2 can be observed conveniently. The liquid replenishing bottle 2 can be selected from a hard bottle body or a soft bottle body, and the bottle body of the liquid replenishing bottle 2 can be vertically placed as shown in fig. 4; or the body of the liquid replenishing bottle 2 is placed right as shown in figures 1-3.

The bottle cavity of the drainage bottle 1 can be an independent and complete bottle cavity or can be divided into two bottle cavities. Specifically, in order to observe the color and the property of the new drainage liquid and measure the new drainage liquid, a partition plate 14 is arranged in the bottle body of the drainage bottle 1, and the partition plate 14 divides the bottle cavity into a first cavity 15 and a second cavity 16 which are separated from each other at the bottom and communicated with each other at the upper part, as shown in figures 1-4. The lower end of the catheter 12 is positioned at the bottom of the second chamber 16, and the volume scale is arranged on the bottle body corresponding to the second chamber 16. The second chamber 16 is adapted to receive the drainage fluid directly, and the volume of the second chamber 16 is small, so that even a small amount of drainage fluid can produce a large level change in the second chamber 16 to facilitate direct viewing of the measurement.

The portion of the catheter tube 12 inside the drainage vial 1 is preferably a rigid tube, and the lower end of the catheter tube 12 is located at the bottom of the second chamber 16 of smaller volume, which naturally prevents the catheter tube 12 from slipping out of the second chamber 16. After a certain observation period, the drainage fluid in the second chamber 16 can be poured into the first chamber 15 to facilitate re-metering of the drainage fluid for the next observation period. The body of the first chamber 15 is also preferably provided with volume graduations, and the second switch 13 is provided on the outside of the body of the catheter 12. When the drainage bottle 1 is dumped, the second switch 13 needs to be closed firstly; after the drainage bottle 1 is aligned, the lower end of the drainage tube 12 is sealed, and then the second switch 13 is opened. The second switch 13 can be a knob switch or a clip. To facilitate control of the angle at which the bottle 1 is poured, the second chamber 16 of the bottle 1 is provided with a sloped surface 18 on the side away from the first chamber 15, and referring to fig. 3 and 4, the sloped surface 18 is parallel to the plane of the partition 14.

The partition 14 can be vertically arranged in the bottle cavity of the drainage bottle 1, but the better proposal is that the partition is obliquely arranged, so that the second chamber 16 is in a shape of big top and small bottom, and even if the quantity of drainage liquid is less, the liquid level can also generate more obvious liquid level change. In order to realize the liquid seal of the lower end of the catheter 12 in the new observation period, the liquid can be supplemented by the liquid supplementing bottle 2 with a proper amount of sealing liquid, so that the partition plate 14 can be a continuous and flat plate-shaped structure, as shown in fig. 1 and 2; or the partition 14 is provided with a water containing structure 17. The water containing structure 17 is used for intercepting a certain amount of solution when the partition plate 14 is inclined to the horizontal state when the drainage liquid in the second chamber 16 is poured into the first chamber 15; after the drainage bottle 1 is righted, that is, after the drainage bottle 1 is horizontally placed, the solution in the water containing structure 17 automatically flows back to the second chamber 16, and the lower end of the liquid guide tube 12 realizes liquid seal. Fig. 3 and 4 show two embodiments of the water containing structure 17, wherein the water containing structure 17 in fig. 3 is in an arc-shaped groove shape or a hemispherical shape, i.e. the water containing structure 17 is an open structure; alternatively, the water containing structure 17 is in the shape of a cavity, the lowest part of the cavity is provided with a through hole, and the through hole is obliquely downward communicated with the second chamber 16, as shown in fig. 4. In order to facilitate the solution in the second chamber 16 to flow into the water containing structure 17, the partition 14 is preferably provided with a diversion groove, and when the drainage liquid in the second chamber 16 is poured into the first chamber 15, the drainage liquid flows into the water containing structure 17 along the diversion groove first and then overflows from the water containing structure 17 into the first chamber 15.

The water containing structure 17 is preferably disposed at an upper portion of the partition 14 to prevent the water containing structure 17 from being disposed near the lower end of the liquid guiding tube 12. The volume of the water containing structure 17 should not be too large, so that the volume of solution can effectively seal the lower end of the catheter 12. In order to directly measure the drainage fluid in one observation period, the zero scale line of the volume scale of the second chamber 16 is not located at the bottom of the second chamber 16, and the volume below the zero scale line of the volume scale line of the second chamber 16 is equal to the volume of the water containing structure 17.
