Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a device for extracting tumor effusion. Background Art

[0002] Tumor effusion is a common complication of tumors, and if the disease cannot be removed, the effusion will exist for a long time. If the effusion is not extracted in time, the long-term accumulation of tumor effusion will not only affect the patient's physical health, but also accelerate the deterioration of the tumor. The existing technology generally treats by extracting the effusion, so a tumor effusion extraction device is used. However, the existing tumor effusion extraction device still has some shortcomings. For example, when the patient has too much tumor effusion, a new liquid storage bottle needs to be replaced. The existing method is not only cumbersome during replacement, but also the overall extraction device shakes a lot during replacement, which makes it impossible to extract quickly and avoids secondary injury to the patient. For this reason, we propose an extraction device for tumor effusion. Utility Model Content

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] See also Figure 1-2The utility model provides a technical solution: an extraction device for tumor effusion refers to a device for extracting tumor effusion in the chest cavity of a patient by means of negative pressure, comprising an extraction tube 1 and a matching extraction rod 2. The left side of the extraction rod 2 is located in the inner cavity of the extraction tube 1 and is provided with a matching piston. Since it is a prior art, only a brief description is given in the text. An extraction head 3 is provided on the left side of the extraction tube 1, and an air extraction pipe 4 is provided on the left side of the extraction head 3. A three-way joint 5 is provided on the left side of the air extraction pipe 4. A liquid suction pipe 6 is provided on the left side of the three-way joint 5. A puncture needle 7 is provided at one end of the liquid suction pipe 6 away from the three-way joint 5. The puncture needle 7 is inserted into a designated area in the patient's body, and then the extraction rod 2 is pulled to make the extraction tube 1 reach a negative pressure device. At this time, the effusion can be extracted by the cooperation of the air extraction pipe 4, the three-way joint 5 and the liquid suction pipe 6. A liquid outlet pipe 8 is provided at the bottom of the three-way joint 5. The bottom of the liquid outlet pipe 8 is movably connected to the top center of the liquid storage bottle 10 through the matching internal threaded connection cover 9 and the external threaded connection cover 11. When the liquid storage bottle 10 needs to be replaced, the external threaded connection cover 11 and the internal threaded connection cover 9 can be separated by rotating the liquid storage bottle 10. In this way, a new liquid storage bottle 10 can be replaced without removing the puncture needle 7. The front end surface of the liquid storage bottle 10 is vertically provided with a scale line 12, which can be used for medical personnel to observe the amount of extracted effusion.

[0019] Among them, preferably, a control valve 13 is provided on the exhaust pipe 4, and an exhaust pipe 14 is provided on the left side of the top of the extraction cylinder 1. The top of the exhaust pipe 14 is movably connected to a matching sealing cover 15. The control valve 13 is closed and the sealing cover 15 is removed from the top of the exhaust pipe 14. The pulling rod 2 in the extraction cylinder 1 can be pushed to the left to the left side of the inner cavity of the extraction cylinder 1, and then the sealing cover 15 is installed on the top of the exhaust pipe 14, and the control valve 13 is opened, so that the accumulated liquid can be extracted for the second time.

[0020] Preferably, a baffle 16 is vertically arranged at the center of the top of the inner cavity of the three-way joint 5. The length of the baffle 16 from top to bottom is greater than half of the length of the three-way joint 5 from top to bottom. The baffle 16 can block the accumulated liquid, avoid and reduce the flow of the accumulated liquid into the exhaust pipe 4, and a through hole 17 is evenly and horizontally penetrated through the top of the left side of the baffle 16. The through hole 17 can facilitate the flow of air.

[0021] Preferably, the three-way connector 5 is configured as a medical plastic three-way connector, which has low manufacturing cost, light weight, and is easy to use. The three-way connector 5 is configured as a T-shaped equal-diameter three-way connector.

[0022] Embodiment 2:

[0023] Reference Figure 1-2 This embodiment is different from the first embodiment in that: anti-skid pads are bonded to the top and bottom of the extraction tube 1, and the surface of the anti-skid pads is evenly and longitudinally provided with anti-skid convex patterns. This arrangement can increase stability when medical staff hold the extraction tube 1 to avoid hand slippage; the liquid storage bottle 10 is set as a transparent polyvinyl chloride plastic bottle, which is convenient for medical staff to observe the accumulated fluid extracted from the liquid storage bottle 10. A rubber pad is bonded to the bottom of the liquid storage bottle 10, and the rubber pad can increase the stability of the liquid storage bottle 10 placed on the desktop, thereby increasing the anti-skid effect.

[0024] The electrical appliances mentioned in this article are all connected to an external power source through wires.
