Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a drainage puncture device for cardiology. Background Art

[0002] Cardiology puncture is a diagnostic and treatment technique that uses a puncture needle to directly pierce the pericardial cavity. The puncture must be performed under sterile techniques, and procaine anesthesia should be applied locally. The puncture site should not be too deep to avoid puncturing the atrium, ventricle or coronary artery, causing a large amount of blood accumulation in the pericardial cavity. Patients undergoing pericardial puncture can understand the nature of the pericardial effusion by testing the fluid in the pericardial cavity, and identify the cause of pericarditis based on the nature of the pericardial effusion. It is a relatively safe diagnostic and treatment method.

[0003] However, when there is a lot of fluid accumulation after puncture, it is usually necessary to adhere the puncture needle as a whole to the outside of the patient's body. Due to the fixed setting of the holding wing plate of the traditional puncture needle, it cannot ensure that the needle body fits well to the body surface during adhesion. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a drainage puncture device for cardiology, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: a drainage puncture device for cardiology, comprising a puncture mechanism, the puncture mechanism comprising: a puncture needle, a holding mechanism, the holding mechanism comprising: a fixed seat, a holding wing plate, a rotating shaft is connected between the holding wing plate and the fixed seat, both side sections of the fixed seat are equipped with upper clamping seats, the upper surface of the holding wing plate is equipped with a fixed buckle, the interior of the upper clamping seat is provided with a buckle through hole, the upper end of the buckle through hole is equipped with a movable buckle, and both sides of the movable buckle are located inside the upper clamping seat and have movable grooves.

[0006] As a further solution of the present invention: an adhesive layer is installed on the side of the holding wing plate away from the fixing buckle.

[0007] As a further solution of the utility model: one end of the puncture needle is connected to a drainage tube, a negative pressure connector is installed on the outside of the drainage tube, and a liquid storage bag is installed on the end of the drainage tube away from the puncture needle.

[0008] As a further solution of the present invention: the holding wing plate is rotatably connected to the fixing seat via the rotating shaft.

[0009] As a further solution of the utility model: the fixed buckle is engaged with the movable buckle, and the movable buckle is fixedly connected to the upper clamping seat.

[0010] As a further solution of the present utility model: a release paper layer is arranged on the outer side of the adhesive layer.

[0011] As a further solution of the present utility model: the upper card seat is fixedly connected to the fixed seat.

[0012] As a further solution of the present utility model: the puncture needle is connected in a through manner to both the puncture mechanism and the drainage tube.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The entire holding wing plate can rotate on the outer side of the fixed seat through a rotating shaft, and in cooperation with the clamped state of the fixed buckle and the movable buckle, the axis of the entire holding wing plate can be adjusted to be parallel to the puncture needle, which facilitates the fixation of the needle outside the body after puncture.

[0015] The movable slot opened on the upper card seat can accommodate the deformation when the movable buckle is toggled, which can be quickly achieved when the position of the holding wing plate needs to be adjusted, avoiding the trouble of disassembly that may cause the puncture needle to shake inside the pericardium and pose a danger.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1-5 shown, this embodiment provides a drainage puncture device for cardiology, including a puncture mechanism 1. The puncture mechanism 1 includes: a puncture needle 2 and a holding mechanism 6. The holding mechanism 6 includes: a fixed seat 601 and a holding wing plate 602. A rotating shaft 605 is connected between the holding wing plate 602 and the fixed seat 601. The holding wing plate 602 is rotatably connected to the fixed seat 601 through the rotating shaft 605. Upper clamping seats 603 are installed on both side segments of the fixed seat 601. The upper clamping seats 603 are fixedly connected to the fixed seat 601. A fixed buckle 604 is installed on the upper surface of the holding wing plate 602. A buckle through hole 606 is opened inside the upper clamping seat 603. A movable buckle 607 is installed at the upper end of the buckle through hole 606. The fixed buckle 604 is clamped with the movable buckle 607. The movable buckle 607 is fixedly connected to the upper clamping seat 603. Activity slots 608 are opened inside the upper clamping seat 603 on both sides of the movable buckle 607. A paste adhesive layer 609 is installed on the side of the holding wing plate 602 away from the fixed buckle 604. A release paper layer is arranged outside the paste adhesive layer 609.

[0024] As Figures 1-3 shown, in this embodiment, one end of the puncture needle 2 is connected with a drainage tube 3. The puncture needle 2 is connected through the puncture mechanism 1 and the drainage tube 3. A negative pressure connector 4 is installed outside the drainage tube 3. The negative pressure connector 4 is externally connected to a negative pressure source. A liquid storage bag 5 is installed at the end of the drainage tube 3 away from the puncture needle 2.

[0025] The working principle of the present utility model is as follows: Before puncture, the whole holding wing plate 602 is rotated on the outside of the fixed seat 601 by using the rotating shaft 605. After the fixed buckle 604 on the upper surface of the holding wing plate 602 is buckled into the inside of the buckle perforation 606 and limited by the movable buckle 607, the whole holding wing plate 602 can be used for applying force during puncture to facilitate puncture. When the whole puncture needle 2 punctures into the pericardium, the release paper outside the adhesive layer 609 is torn off as a whole. By pulling the movable buckle 607 on the outside of the upper clamping seat 603 upward as a whole, after disconnecting the clamping connection between the movable buckle 607 and the fixed buckle 604, the side of the whole holding wing plate 602 with the adhesive layer 609 is rotated towards the patient's body position. After the whole holding wing plate 602 adheres to the outside of the body, the puncture position is fixed by using a medical bandage, and then the effusion in the pericardium is adsorbed through the drainage tube 3 by using the negative pressure mechanism outside the negative pressure joint 4.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0027] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
