Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a PICC catheter protection device. Background Art

[0002] The full name of PICC tube is Peripherally Inserted Central Catheter. PICC is composed of the first letters of its full English name. PICC tube is a catheter that is inserted through puncture of the peripheral veins on the arm (basilic vein, median cubital vein, cephalic vein), and then passes through the axillary vein, subclavian vein and innominate vein in the direction of the blood vessels, and finally the tip of the catheter is inserted into the superior vena cava. PICC tube provides patients with a convenient, safe, effective and long-term venous channel and is widely used in clinical practice. The catheter material is silicone, which is soft and elastic. Patients with PICC tubes need to wear a protective sleeve. After the catheter is inserted, medical staff generally use tape and cotton to bandage and fix the puncture. When the patient is in a humid environment, the humid air from the outside carries a lot of bacteria, which will directly contact the patient's arm and cause infection, which is not conducive to the patient's recovery.

[0003] Prior art, patent number (CN202120559985.7) mentions a PICC catheter protection device, which relates to the field of medical device technology.

DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] First embodiment

[0020] See also Figure 1 to Figure 3 , Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model. Figure 2 It is a side view of the whole of the first embodiment of the utility model. Figure 3 This utility model Figure 2 AA line structural cross-section view.

[0021] The utility model provides a PICC catheter protection device, comprising an inner shell 101 and a detachable protection component, wherein the detachable protection component comprises a moisture-proof layer 102, a connecting ring 103, an observation groove 108, an outer shell 105, a driving rod 104, a locking groove 106 and a friction groove 107. The above-mentioned solution solves the problem that the protection sleeve cannot be partially disassembled, resulting in the need for overall disassembly when the PICC tube needs to be observed, thereby limiting the scope of use in practical applications. It can be understood that the above-mentioned solution can be used to protect the PICC catheter (central venous catheter) by sleeve-mounting the inner shell 101 on the PICC catheter. In this way, the PICC catheter is protected. When the PICC catheter needs to be observed, the connecting ring 103 is rotated to drive the driving rod 104, and the driving rod 104 drives the engaging groove 106 and the outer shell 105, thereby removing the outer shell 105, and the PICC catheter can be observed through the observation groove 108 without removing the inner shell 101 and the moisture-proof layer 102. This actively and effectively solves the problem that the protective sleeve cannot be partially disassembled, resulting in the need to disassemble the entire PICC tube when it is necessary to observe the PICC tube, thereby limiting its scope of use in practical applications.

[0022] According to this specific embodiment, the moisture-proof layer 102 is detachably connected to the inner shell 101 and is located inside the inner shell 101, the connecting ring 103 is rotatably connected to the inner shell 101 and is located on the outer surface of the inner shell 101, and the observation groove 108 is fixedly connected to the inner shell 101 and is located at the inner center of the inner shell 101.

[0023] Among them, the driving rod 104 is detachably connected to the connecting ring 103 and is located on the outer surface of the connecting ring 103 away from the inner shell 101. The outer shell 105 is detachably connected to the driving rod 104 and is located on a side of the driving rod 104 away from the connecting ring 103. The outer shell 105 is the main component for protecting the whole, and the driving rod 104 is the main component for driving the engaging groove 106 and the outer shell 105 to be disassembled.

[0024] Secondly, the snap-fit ​​groove 106 is fixedly connected to the outer shell 105 and is located inside the outer shell 105. The friction groove 107 is fixedly connected to the outer shell 105 and is located on the inner side of the outer shell 105 away from the snap-fit ​​groove 106. The snap-fit ​​groove 106 is the main component for rotating with the connecting ring 103 to complete the disassembly of the outer shell 105. The friction groove 107 is the main component for facilitating the staff to use the outer shell 105.

[0025] When the utility model is used to protect the PICC catheter, the inner shell 101 is sleeved on the PICC catheter to protect the PICC catheter. When the PICC catheter needs to be observed, the connecting ring 103 is rotated to drive the driving rod 104, and the driving rod 104 drives the engaging groove 106 and the outer shell 105, thereby removing the outer shell 105, thereby observing the PICC catheter through the observation groove 108 without removing the inner shell 101 and the moisture-proof layer 102, thereby actively and effectively solving the problem that the protective sleeve cannot be partially disassembled, resulting in the need to disassemble the entire PICC tube when it is necessary to observe the PICC tube, thereby limiting its scope of use in practical applications.

[0029] According to this specific embodiment, the connecting sleeve 201 is detachably connected to the outer shell 105 and is located on one side of the outer shell 105. The buffer ring 202 is detachably connected to the connecting sleeve 201 and is located on a side of the connecting sleeve 201 away from the outer shell 105. The blocking ring 203 is detachably connected to the buffer ring 202 and is located on a side of the buffer ring 202 away from the connecting sleeve 201. The connecting sleeve 201 is a main component connecting the outer shell 105 and the buffer ring 202. The buffer ring 202 is a main component for reducing the displacement of the inner shell 101 due to external force during activities, and the blocking ring 203 is a main component for preventing the inner shell 101 from being displaced due to external force.

[0030] The blocking plate 205 is rotatably connected to the blocking ring 203 and is located on the side of the blocking ring 203 away from the buffer ring 202. The protective cover 204 is arranged on the outer surfaces of the blocking ring 203 and the blocking plate 205. The protective cover 204 is the main component for protecting the blocking plate 205 and the blocking ring 203, and the blocking plate 205 is the main component for performing blocking operations.
