Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a suction cup for closing a puncture point. Background Art
[0002] Thoracentesis and abdominal paracentesis drainage are common clinical treatment / diagnostic operations. Clinically, it is often encountered that after the drainage tube is removed at the end of drainage, the puncture point shows repeated exudation, and the thoracic and abdominal fluids continuously ooze out from the puncture point, resulting in repeated dressing changes, changing clothes, etc. In severe cases, it can lead to infection at the puncture point, etc. Clinically, it is usually treated by compression bandaging or directly suturing at the puncture point. When the exudate pressure is relatively large, the compression bandaging usually has a poor effect, and suturing will increase the patient's trauma and subsequent troubles such as removing the sutures again. In clinical practice, ostomy bags are also used to fix and drain puncture fluids, but they are usually large in volume and troublesome for patients to operate. Therefore, we provide a suction cup for closing a puncture point to solve the above problems. Content of the Utility Model
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a suction cup for closing a puncture point.
[0004] The purpose of the utility model is realized by the following technical solutions:
[0005] A suction cup for closing a puncture point includes a suction cup. A protrusion is arranged on the outer surface of the suction cup. The protrusion is communicated with the inside of the suction cup and integrally formed. A one-way valve structure is arranged inside the protrusion. When in use, the protrusion is communicated with an external air extraction component to extract air from the inside of the suction cup.
[0006] Preferably, an installation plane is arranged at the center of the outer surface of the suction cup, and the protrusion is arranged on the installation plane.
[0007] Preferably, an inner disk body is arranged on the inner top surface of the center of the suction cup. An air cavity is formed between the inner disk body and the inner wall of the suction cup. The protrusion is communicated with the air cavity and the protrusion is not coaxial with the inner disk body.
[0008] Preferably, a receiving cavity is opened inside the inner disk body.
[0009] Preferably, the one-way valve structure includes a through hole opened on the upper surface of the protrusion and communicated with the inside of the suction cup. A connecting shaft is arranged inside the through hole. A top sealing piece for closing the opening outside the through hole is integrally arranged at the top of the connecting shaft. A bottom sealing piece for closing the opening inside the through hole is integrally arranged at the bottom of the connecting shaft. A plurality of air passing holes communicating with the through hole and the inside of the suction cup are opened on the bottom sealing piece.

[0026] As Figure 1 — Figure 6 shown in the embodiment.
[0027] A suction cup for closing a puncture point, including a suction cup 1. A protrusion 2 is provided on the outer surface of the suction cup 1. The protrusion 2 is in communication with the inside of the suction cup 1 and integrally formed. A one-way valve structure 3 is provided inside the protrusion 2. When in use, the protrusion 2 is in communication with an external air extraction assembly 4 to extract air inside the suction cup 1.
[0028] Refer to Figure 1 and Figure 2 shown. When in use, the air extraction assembly 4 is connected to the protrusion 2 to extract air inside the suction cup 1. During the air extraction process, since the air inside the suction cup 1 gradually decreases, the suction cup 1 will gradually sink and contract inward, thereby driving the skin and subcutaneous tissues around the puncture point to gather towards the center, so as to close the puncture channel and achieve the effect of accelerating the rapid healing of the transfer point; compared with the existing bandaging and suturing methods, this suction cup is simple to operate and convenient to use, and greatly reduces the pain of patients compared with the suture method.
[0029] In this embodiment, the size and thickness of the suction cup 1 can be designed according to needs, and the materials used to make the suction cup 1 are all medical grade, thereby preventing the occurrence of wound infection and the like due to material reasons.
[0030] A mounting plane 5 is disposed at the center of the outer surface of the suction cup 1 , and the protrusion 2 is disposed on the mounting plane 5 .
[0031] In this embodiment, the protrusion 2 may also be disposed at other positions on the suction cup 1 , and the specific position is not limited here.
[0032] An inner disk body 6 is disposed on the central inner top surface of the suction cup 1, an air cavity 7 is formed between the inner disk body 6 and the inner wall of the suction cup 1, the protrusion 2 is connected to the air cavity 7 and the protrusion 2 is not coaxial with the inner disk body 6; an accommodating cavity 8 is opened inside the inner disk body 6.
[0033] participate Figures 2 to 4 As shown, if the interior of the inner disk body 6 is solid, it can abut against the puncture point, thereby preventing the puncture fluid from flowing out; in other embodiments, a receiving cavity 8 can be opened inside the inner disk body 6, and certain dressings or gauze and other medical supplies beneficial to wound healing are placed in the receiving cavity 8 before use; the medical supplies are wrapped around the puncture point, thereby accelerating the healing of the puncture point.
[0034] The one-way valve structure 3 includes a through hole 31 opened on the upper surface of the protrusion 2 and connected with the interior of the suction cup 1, a connecting shaft 32 is arranged inside the through hole 31, a top sealing piece 35 for closing the external opening of the through hole 31 is integrally arranged on the top of the connecting shaft 32, and a bottom sealing piece 33 for closing the interior of the through hole 31 is integrally arranged on the bottom of the connecting shaft 32, and a plurality of air holes 34 connected to the through hole 31 and the interior of the suction cup 1 are opened on the bottom sealing piece 33.
[0035] See also Figures 1 to 6 As shown, when vacuuming is performed, the negative pressure generated by the vacuum assembly 4 will drive the top sealing piece 35 and the through hole 31 to move upward, so that an air gap is formed between the top sealing piece 35 and the upper surface of the protrusion 2, so that the gas inside the suction cup 1 is conveniently extracted from the gap; because the bottom is blocked by the bottom sealing piece 33, the connecting shaft 32 will not separate from the through hole 31, and the gas inside the suction cup 1 enters the through hole 31 through the air hole 34 and is then extracted from the gap between the top sealing piece 35 and the top opening of the through hole 31. In this process, the air in the suction cup 1 enters the through hole 31 through the air hole 34, and then the gas passes through the through hole 31 and the gap between the top sealing piece 35 and the protrusion 2 and is extracted by the vacuum assembly 4, so that the inside of the suction cup 1 is in a negative pressure state, thereby driving the skin and subcutaneous tissue around the puncture point to move toward the center and squeeze the puncture channel to close.
[0036] In order to enable the gas in the suction cup 1 to be smoothly pumped out, the connecting shaft 32 is smaller than the diameter of the through hole 31, and the air passing hole 34 is located directly below the air passing channel formed between the through hole 31 and the connecting shaft 32; further, for the convenience of installation, the connecting shaft 32, the bottom sealing piece 33 and the top sealing piece 35 can be made of deformable materials; the sizes of the through hole 31, the connecting shaft 32, the air passing hole 34 and the top sealing piece 35 can be designed according to actual needs and are not limited here, and the materials used for production are all of medical grade to prevent wound infection.
[0037] A ring groove 9 adapted to the air extraction assembly 4 is provided on the upper surface of the protrusion 2, and the ring groove 9 is coaxial with the protrusion 2.
[0038] Refer to Figures 3 to 5 As shown, in order to enable the air extraction assembly 4 to more easily pump out the gas in the suction cup 1, before air extraction, the air extraction end of the air extraction assembly 4 is inserted into the ring groove 9, so as to play a sealing role to a certain extent, prevent external gas from being extracted by the air extraction assembly 4, and make the air extraction smoother.
[0039] A sealing gasket 10 is provided on the bottom surface of the ring groove 9.
[0040] Refer to Figures 3 to 5 As shown, by providing the sealing gasket 10 on the bottom surface of the ring groove 9, the sealing gasket 10 is brought into contact with the bottom surface of the air extraction end of the air extraction assembly 4, so as to realize the sealing of the air extraction end of the air extraction assembly 4, further improve the sealing effect, improve the smoothness of air extraction, and thus be able to form sufficient negative pressure at the air extraction end of the air extraction assembly 4 to pump out the gas in the suction cup 1.
[0041] The air extraction assembly 4 includes an air cylinder 41, a joint 42 adapted to the ring groove 9 is provided at the bottom of the air cylinder 41, a piston 43 is arranged inside the air cylinder 41, and an air extraction rod 44 extending outside the air cylinder 41 is installed at the top of the piston 43.
[0042] Refer to Figure 4 and Figure 5 As shown, when air extraction is carried out, the joint 42 is inserted into the ring groove 9 and brought into contact with the sealing gasket 10 inside the ring groove 9 to realize the sealing of the air inlet of the joint 42. At this time, the top sealing piece 35 and the top opening of the through hole 31 are located inside the joint 42, and the diameter of the top sealing piece 35 is smaller than the inner diameter of the joint 42, so that a corresponding gas channel can be formed between the top sealing piece 35 and the joint 42, and thus the gas from the suction cup 1 can be pumped out. During the pumping process, the piston 43 is pulled upward by the air extraction rod 44 to form a negative pressure at the position of the joint 42, so that a gap is formed between the top sealing piece 35 and the top opening of the through hole 31 for the gas to be pumped out.
[0043] The working process of the present utility model is as follows: Lubricating oil can be applied at the puncture point first to increase the sealing performance between the suction cup 1 and the skin, and then the suction cup 1 is attached to the puncture point position. Next, the connector 42 is fitted with the annular groove 9 and abuts against the gasket 10 to seal the connector 42. Then, the air extraction rod 44 is pulled to drive the piston 43 to move upward to form negative pressure at the position of the connector 42. Under the action of the negative pressure, the top sealing piece 35 and the connecting shaft 32 move upward so that an air passing gap is formed between the top sealing piece 35 and the top outlet of the through hole 31. At this time, as the air extraction rod 44 drives the piston 43 to continuously extract air, the air in the suction cup 1 enters the through hole 31 through the air passing holes 34, and then enters the connector 42 until the air cylinder 41 through the gap at the top outlet of the through hole 31, completing the extraction of the air inside the suction cup 1. During the extraction process, the suction cup 1 is concave deformed, which drives the skin and subcutaneous tissue around the puncture point to move closer to and squeeze the puncture point and the puncture channel, thereby closing the puncture channel. After the air extraction is completed, the suction cup 1 and the skin can be covered with a gauze to prevent accidental contact during activities (35) from allowing external gas to enter the suction cup (1) and causing the suction cup 1 to separate from the skin; if the negative pressure in the suction cup 1 is too large, the top sealing piece 35 can also be manually lifted to allow external gas to enter the suction cup 1 to reduce the negative pressure intensity in the suction cup 1.
[0044] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
