Abstract
The utility model provides a thoracic and abdominal cavity aspirator. A three-way valve is mounted on the taperd of a conventional injector, one head of the three-way valve is matched with the taperd of the injector, the other two ends are a fluid inlet and a fluid outlet respectively, and one one-way valve is arranged in the fluid inlet and the fluid outlet respectively. One medical catheter is connected on the fluid inlet, and a puncture steel needle is connected at the end of the catheter; another medical catheter is connected on the fluid outlet, and a drainage bag is connected at the end of the catheter. When the in vivo body fluid of a patient is aspirated, the one-way valve of the fluid inlet is opened, the body fluid can be aspirated into an injector, and at this time, the one-way valve of the fluid outlet is closed. Afterwards, the push rod of the injector is pushed, the one-way valve of the fluid outlet is opened, the body fluid can be drained into the drainage bag through the conduit pipes, and at this time, the one-way valve of the fluid inlet is closed. The body fluid can be aspirated and drained repeatedly till the requirements for surgeries are conformed. The thoracic and abdominal cavity aspirator has the advantages that the operation is convenient for medical staff, the labour intensity can be reduced, and the medical staff and working environments cannot be polluted by the body fluid of the patient.
Description
Technical field
This utility model relates to a kind of liquid extracting device of using in the bodies such as abdominal cavity, thoracic cavity of being used for, and belongs to medical instruments field.
Background technology
Hospital is used for the general injector for medical purpose with big specification of utensil of the interior liquid suctions of body such as abdominal cavity, thoracic cavity at present, as 50mL.Because general patient's the thoracic cavity or the body fluid in abdominal cavity are more, reach mL more than 1000 sometimes, the medical worker will repeatedly aspirate the patient.The medical worker earlier the patient body fluid extract out, again syringe is transferred to, the body fluid in the syringe is discharged repeated multiple times like this.The medical worker is very loaded down with trivial details when operation, moreover the medical worker pollutes the medical worker and the working environment of operation easily when the body fluid in the syringe is discharged.
Summary of the invention
The utility model proposes a kind of structure of new abdominal cavity, thoracic cavity liquid extracting device, reaching medical worker's drawing liquid and discharge opeing continuously when the suction body fluid, and patient's body fluid is in the state of sealing in whole drawing liquid and discharge opeing process.
The purpose of this utility model reaches by implementing following technical scheme: adorn a three-way valve on the conventional syringe conehead, one of three-way valve matches with the syringe conehead, and one at two ends are inlet in addition, and one is liquid outlet.In respectively adorn a check valve.Connect a medical catheter on the inlet, the not end of conduit connects a root puncture draw point, connects a medical catheter on the liquid outlet, and conduit is not held and connected a drainage bag.When in patient's body, taking out body fluid, the inlet one-way valve opens, body fluid is drawn in the syringe, and this moment, the check valve of liquid outlet was in closed condition.Push away injector push-rod then, the liquid outlet one-way valve opens, body fluid is discharged into drainage bag by conduit, and this moment, the check valve of inlet was in closed condition.Drawing liquid and discharge opeing repeatedly is until finishing.Make the simple to operate of medical worker thereby reach, reduce labor intensity, and make patient's body fluid not pollute the purpose of medical worker and working environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sketch map of check valve of the present utility model.
Among the figure: 1. syringe, 2. three-way valve, 3. check valve, 4. puncture needle, 5. puncture locator, 6. drainage bag, 7. conduit, 8. inlet, 9. liquid outlet.
The specific embodiment
Accompanying drawing has been represented structure of the present utility model and embodiment, and this abdominal cavity, thoracic cavity liquid extracting device connects three-way valve (2) by the conehead of syringe (1), and the opposite check valve of both direction (3) is housed in the three-way valve (2).Inlet (8) connects a conduit (7), and the other end of conduit (7) connects puncture needle (4).Liquid outlet (9) connects a conduit (7), and the other end of conduit (7) connects drainage bag (6).Check valve (3) in the inlet (8) can only feed liquor, and liquid outlet (8) internal check valve (3) can only fluid.The degree of depth of puncture locator (5) scalable puncture.
Describe below and utilize operating process of the present utility model, during operation, the sterilization of conventional earlier location is carried out local anesthesia, the degree of depth of thrusting as required again, regulate with puncture locator of the present utility model (5), reuse puncture needle of the present utility model (4) thrusts patient's chest or abdominal part, takes out syringe (1) and aspirates, and the check valve (3) in the inlet (8) is opened, body fluid is drawn in the syringe (1), and the check valve (3) in liquid outlet this moment (9) is in closed condition.Push away syringe (1) discharge opeing then, the check valve (3) in the liquid outlet (9) is opened, and body fluid is discharged into drainage bag by conduit (7), and the check valve (3) in inlet this moment (8) is in closed condition.Carry out drawing liquid and discharge opeing repeatedly, till meeting requirements of operation.
Claims (3)
1. abdominal cavity, thoracic cavity liquid extracting device, by syringe, three-way valve, medical catheter, puncture needle, drainage bag is formed, and it is characterized in that:, one of three-way valve matches with the syringe conehead, one at two ends are inlet in addition, and one is liquid outlet, respectively adorns a check valve in inlet and the liquid outlet, connect a medical catheter on the inlet, the not end of conduit connects a root puncture draw point, connects a medical catheter on the liquid outlet, and conduit is not held and connected a drainage bag.
2. abdominal cavity, thoracic cavity according to claim 1 liquid extracting device is characterized in that: one on two check valves in the three-way valve can only feed liquor, and another can only fluid.
