Description

Technical Field

[0001] This utility model relates to the field of cardiovascular medicine technology, and in particular to a patient fixation device for pericardial drainage. Background Technology

[0002] A pericardial drainage tube is a medical device implanted in cases of pericardial effusion or other complications to reduce pressure on the pericardium and relieve symptoms. It is typically placed on the patient after surgery to allow fluid or pus within the pericardial cavity to drain out, preventing excessive fluid buildup that could lead to infection and aiding in wound healing. The primary purpose of using a pericardial drainage tube is to ensure effective drainage of fluid from the pericardium, and it is removed appropriately once the patient's condition improves to avoid unnecessary complications.

[0003] After coronary angiography or stent implantation, patients may experience serious complications such as cardiac tamponade, requiring emergency pericardiocentesis for drainage. Observation of the pericardial drainage after puncture is crucial. Currently, 3M soft adhesive tape is used for fixation in clinical practice. However, if the patient's position changes, the tape may slip out, which can seriously endanger the patient's life. Utility Model Content

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0038] Example 1: Refer to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a pericardial drainage patient fixation device, which can realize the fixation of patients after coronary angiography or stent implantation. Patients may have serious complications such as cardiac tamponade and need emergency pericardial puncture and drainage. It is crucial to observe the pericardial drainage status after puncture. Currently, 3M soft adhesive tape is used for fixation in clinical practice. If the patient's body position changes, it is easy to slip off. Once the tube slips off, it seriously endangers the patient's life. The device includes a strapping mechanism 1, which includes a first elastic strap body 101 and a second elastic strap body 102. The inner walls of the first elastic strap body 101 and the second elastic strap body 102 are both equipped with a protective layer 103.

[0039] The positioning and fixing mechanism 2 includes a positioning frame 201. The side walls at both ends of the positioning frame 201 are fixedly connected to one end of the first elastic bandage body 101 and the second elastic bandage body 102, respectively. A first through hole 202 is opened inside the positioning frame 201, and a pericardial drainage tube body 203 is arranged inside the first through hole 202. An observation window 204 is opened on one side wall of the positioning frame 201. A sturdy plate 205 is installed on one side wall of the positioning frame 201, and an induction spotlight 206 is installed at the end of the sturdy plates 205 that are close to each other. A positioning and fixing component 207 is arranged inside the first through hole 202.

[0040] The positioning and fixing component 207 includes a second through hole 2071, which is formed on the side wall of the positioning frame 201. The second through hole 2071 is connected to the first through hole 202. A connecting rod 2072 is provided inside the second through hole 2071, and a positioning plate 2074 is installed at one end of the connecting rod 2072. A push plate 2073 is installed on the side wall of one end of the connecting rod 2072, and a rubber pad 2075 is installed on the side wall of the positioning plate 2074. The push plate 2073 and the connecting rod 2072 are welded together as an integral structure, which makes it easy for the operator to pull the push plate 2073 to drive the connecting rod 2072 to slide inside the second through hole 2071.

[0041] The outer wall of the positioning plate 2074 is equipped with a first spring body 2076, and the end of the first spring body 2076 away from the positioning plate 2074 is fixedly connected to the inner wall of the first through hole 202. Through the design of the first spring body 2076, the positioning plate 2074 is positioned and fixed by the elastic recovery of the first spring body 2076.

[0042] The outer wall of the connecting rod 2072 is fitted with a second spring body 2077, and the two ends of the second spring body 2077 are fixedly connected to the positioning plate 2074 and the inner wall of the first through hole 202, respectively; the elastic recovery of the second spring body 2077 drives the connecting rod 2072 to slide back and forth inside the first through hole 202.

[0043] The specific working principle is as follows: when it is necessary to position and fix the pericardial drainage tube body 203, the push plate 2073 is first pulled to drive the connecting rod 2072 to slide inside the second through hole 2071 and pull the positioning plate 2074 to compress the first spring body 2076 and the second spring body 2077 to deform. This allows the positioning plate 2074 and the rubber pad 2075 to slide back and forth through the elastic recovery of the first spring body 2076 and the second spring body 2077, which facilitates the positioning and fixation of the pericardial drainage tube body 203 and avoids the tube slippage from seriously endangering the patient's life. At the same time, the design of the sensor-activated spotlight 206 makes it easy for nursing staff to automatically light up when they arrive, thus facilitating their observation.

[0044] Example 2: Refer to Figures 1-5This is the first embodiment of the present invention. This embodiment provides a pericardial drainage patient fixation device, which can be used to address the serious complications such as cardiac tamponade that may occur after coronary angiography or stent implantation, requiring emergency pericardial puncture and drainage. Observation of the pericardial drainage status after puncture is crucial. Currently, 3M soft adhesive tape is used clinically for fixation, but it is prone to slippage if the patient's position changes. Once the tube slips, it seriously endangers the patient's life. The tension adjustment mechanism 3 includes a wearing frame 301, which is fixedly connected to the end of the first elastic bandage body 101 away from the positioning frame 201. A third through hole 302 is opened on one side wall of the wearing frame 301. A winding rod 303 is rotatably installed inside the wearing frame 301 through a bearing, and the outer wall of the winding rod 303 is fixedly connected to the second elastic bandage body 102. A gear body 304 is fixedly installed on the outer wall of the winding rod 303. A welding plate 305 is installed on the side wall of the wearing frame 301.

[0045] The welding plate 305 has a fourth through hole 306 inside, and a first crossbar body 307 is arranged inside the fourth through hole 306. A guide plate 308 is installed at one end of the first crossbar body 307, and a toothed block body 309 is installed at the end of the guide plate 308 away from the first crossbar body 307. The toothed block body 309 meshes with the gear body 304. A third spring body 3013 is sleeved on the outer wall of the first crossbar body 307, and the two ends of the third spring body 3013 are fixedly connected to the guide plate 308 and the side wall of the welding plate 305, respectively. Through the cooperation between the fourth through hole 306 and the first crossbar body 307, the first crossbar body 307 slides inside the fourth through hole 306, thereby driving the guide plate 308 and the toothed block body 309 to slide.

[0046] The top of the wearing frame 301 has a groove 3010, and the side walls at both ends of the groove 3010 are fitted with a second crossbar body 3011. The outer wall of the second crossbar body 3011 is fitted with an installation collar 3012, and the outer wall of the installation collar 3012 is fixedly connected to the outer wall of the guide plate 308. Through the cooperation of the installation collar 3012 and the second crossbar body 3011, the guide plate 308 slides on the outer wall of the second crossbar body 3011 via the installation collar 3012.

[0047] The specific working principle is as follows: when it is necessary to adjust the tension of the first elastic bandage body 101 and the second elastic bandage body 102, the first crossbar body 307 is first pulled to slide inside the fourth through hole 306, which drives the guide plate 308 and the toothed block body 309 to compress the third spring body 3013 and cause it to deform. By installing the collar 3012 and the second crossbar body 3011 in cooperation, the guide plate 308 and the toothed block body 309 slide and no longer engage with the gear body 304. At the same time, the tension of the second elastic bandage body 102 is adjusted by rotating the winding rod 303, which makes it easier for nursing staff to put the first elastic bandage body 101 and the second elastic bandage body 102 on the patient's body, thus facilitating the operation of nursing staff.

[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
