Description

Drainage device

Technical Field

The utility model relates to a drainage equipment field, in particular to drainage device.

Background

The drainage bag is a common medical auxiliary apparatus and comprises a drainage tube, a liquid discharge tube and a transparent liquid storage bag which is specially used for containing drained liquid; the drainage tube and the liquid discharge tube are respectively connected with two ends of the liquid storage bag; the drainage tube is provided with a flow-limiting clamp and a drainage valve. The drainage bag is widely used in cardiovascular medicine, urology department and the like, and is mainly used for leading out oozing blood, effusion and the like in the body or in the deep part of a local operation of a patient after an operation.

When the drainage bag is used, effusion or oozing blood and the like in the liquid storage bag need to be continuously monitored, on one hand, the effusion and the like oozing amount of a patient need to be detected so as to observe the state of an illness of the patient; on the other hand, the condition that the accumulated liquid flows back to the patient body and even the accumulated liquid in the patient body cannot flow out to aggravate the patient is avoided due to the fact that the accumulated liquid and the like are excessively stored in the liquid storage bag.

Monitoring the effusion in the liquid storage bag is mainly carried out by family members of the patient and the patient; however, patients who use the drainage bag are generally weak and difficult to monitor the liquid storage bag at any time. The amount of accumulated liquid in the liquid storage bag is difficult to monitor at any time due to the fact that the family members of the patient often go out temporarily and the like. Aiming at the situation, the current main solution is that the effusion in the liquid storage bag is firstly poured out by a patient before going out so as to reduce the backflow of the effusion in the liquid storage bag; but the problem is difficult to be solved fundamentally due to variable factors such as the outgoing time and the effusion flow of the patient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a drainage device to solve the problems that the drainage bag in the prior art has excessive accumulated liquid in the liquid storage bag, so that the accumulated liquid flows back or cannot flow out of the body; thereby affecting the health of the patient.

The drainage device comprises a drainage bag and an adjusting mechanism; the drainage bag comprises a liquid storage bag, a drainage tube and a drainage tube, wherein the drainage tube and the drainage tube are connected to the two ends of the liquid storage bag;

the adjusting mechanism comprises an adjusting bag, an inner pipe, an outer pipe and a blocking block; the liquid storage bag is positioned in the adjusting bag, and a closed cavity is formed between the adjusting bag and the liquid storage bag; the blocking block is hermetically connected to one end of the outer pipe, a through groove is formed in the outer wall of the blocking block along the length direction of the outer pipe, the other end of the outer pipe is communicated with the adjusting bag, an air duct is arranged in the wall body of the outer pipe, a flow guide hole is formed in the inner wall of the outer pipe, and the air duct is used for communicating the flow guide hole with the cavity; the inner tube is the flexible tube and is located the outer tube, and the one end intercommunication of inner tube the liquid storage bag, the other end and the laminating of sprue and shutoff of inner tube lead to the groove.

The working principle and the beneficial effects of the scheme are as follows: when in use, the drainage tube is connected with the part of a patient needing to extract the effusion, and the extraction speed of the effusion is controlled by the current-limiting clamp; the effusion enters the liquid storage bag from the drainage tube. When the accumulated liquid in the liquid storage bag reaches a certain amount, the liquid discharge valve is opened to discharge the accumulated liquid in the liquid storage bag into the accumulated liquid basin from the liquid discharge pipe, and then the accumulated liquid in the accumulated liquid basin is poured.

When a person monitoring the accumulated liquid amount in the liquid storage bag needs to go out, one end of the adjusting mechanism, which is far away from the liquid storage bag, is connected with the accumulated liquid basin; discharge gradually in the stock solution bag along with the hydrops in the patient's body, the stock solution bag inflation for the gas in the cavity receives the extrusion between stock solution bag and the regulation bag, receives extruded gas from the cavity through the air flue, flows out from the water conservancy diversion hole again, and when gas received the extrusion volume in the cavity reached regularly, received extruded gas impact inner tube, made the inner tube part to inside skew. At the moment, the through groove on the outer wall of the block is communicated with the inner pipe, and the accumulated liquid in the liquid storage bag flows into the accumulated liquid basin from the through groove on the block through the inner pipe; thereby avoided the hydrops in the stock solution bag too much, lead to hydrops backward flow or hydrops can't take place from the internal outflow's of patient the body condition.

Furthermore, the adjusting bag is detachably connected to the liquid storage bag, and a connecting hole connected with the inner pipe is formed in the liquid storage bag. The adjusting mechanism is a whole body which is detachably connected on the liquid storage bag by arranging the connecting hole on the liquid storage bag and detachably connecting the adjusting bag on the liquid storage bag; the repetitive use of the adjustment mechanism can be facilitated.

Further, the outer tube is a rigid tube. The outer pipe is set to be a rigid pipe, and when gas flows through the air passage, the deformation of the inner pipe can be increased due to the rigidity of the outer pipe, so that effusion in the inner pipe can flow out conveniently.

Furthermore, an external pipe is sleeved at one end, far away from the inner pipe, of the blocking block. Through the connection of external pipe, be convenient for be connected between adjustment mechanism and the hydrops basin.
