Description

Technical Field

[0001] The invention relates to the technical field of medical endoscopes, and in particular to an endoscope host with a suction pump arranged therein. Background Art

[0002] Medical endoscopes are often used in medical and other places. During the examination of patients, water is injected into the human body as needed to flush the part to be inspected in order to collect clearer images. Similarly, after sampling the part to be inspected, blood is often produced. In order not to affect the detection effect, the blood needs to be sucked out by a suction pump. At present, in fixed inspection places in hospitals, the suction pump is separately set from the endoscope host, which can meet the inspection needs of the endoscope; but if it is used in the field or other emergency rescue places and needs to be moved at any time, the separately set endoscope host and suction pump are difficult to carry, which is inconvenient in use.

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0035] like Figure 1-8 As shown, the endoscope host with a built-in suction pump in this embodiment includes a chassis 1, a suction pump 3 arranged in the chassis 1 and connected to the chassis, a connecting pipe 4 connected to the suction pump at one end, and a connector 6 arranged at the free end of the connecting pipe for connecting to a sewage box 5.

[0036] When the endoscope is working, water is injected into the human body as needed to rinse the endoscope lens or clean the part to be inspected. In this process, waste liquid contaminated with body fluids or blood will be generated. The sewage box is set to collect the waste liquid. When the sewage box is full, it can be removed and discarded.

[0037] In this embodiment, the sewage box 5 is located outside one end of the chassis 1, and a through hole 101a for the free end of the connecting pipe 4 to pass through is provided in the end plate 101 of the end of the chassis 1, and the joint 6 is located outside the chassis 1. Here, the sewage box can be connected to the chassis in a detachable connection, or the sewage box can be directly placed outside the end of the chassis 1 and connected to the suction pump through the connecting pipe 4. Of course, the sewage box 5 can also be built into the chassis and fixed in a common snap connection method, such as using a snap connection structure between a laptop battery and a laptop.

[0038] In order to limit and fix the suction pump 3, a shock-absorbing bracket fixed on the chassis bottom plate 102 is further provided in the chassis 1. The suction pump 3 is connected to the chassis bottom plate 102 and is located in the shock-absorbing bracket.

[0039] In this embodiment, the shock-absorbing bracket includes a door-shaped frame 7, an inner frame 8 and an upper horizontal plate 9 for connecting the two. The door-shaped frame 7, the inner frame 8 and the upper horizontal plate 9 are integrally formed.

[0040] One end of the suction pump 3 is located in the door-shaped frame, and the other end is located in the inner frame.

[0041] The door-shaped stand 7 includes two first vertical plates 701 parallel to each other, and first horizontal plates 702 whose two ends are fixedly connected to the upper ends of the two first vertical plates; the lower end outer surfaces of the two first vertical plates are each provided with a first connecting plate 703 which is perpendicular to and fixedly connected to the first vertical plates, and the first connecting plate 703 is fixedly connected to the chassis bottom plate. With such a structure, the two sides of one end of the suction pump 3 arranged in the door-shaped stand 7 are limited by the two first vertical plates 701, so as to prevent the end of the suction pump 3 from being separated from the door-shaped stand.

[0042] In order to prevent one end of the suction pump 3 disposed in the gate-shaped bracket 7 from being separated from the gate-shaped bracket 7 along the axial direction of the suction pump 3, a first baffle 704 is further included, the two ends of which are respectively fixedly connected to the outer side surfaces of the two first vertical plates 701 and the first baffle is perpendicular to the two first vertical plates 701; the first baffle 704 is located outside one end of the suction pump 3. The inner wall of the first baffle 704 is in contact with the suction pump 3 or not.

[0043] For ease of processing, the first vertical plate 701, the first horizontal plate 702, the first connecting plate 703 and the first baffle plate 704 are integrally formed.

[0044] The inner stand 8 for placing the other end of the suction pump 3 is formed in one piece by a second bottom plate 801 , two second stand plates 802 vertically arranged on the second bottom plate, and an upper arc plate 803 .

[0045] In order to prevent one end of the suction pump 3 arranged in the inner frame 8 from detaching from the inner frame 8 along the axial direction of the suction pump 3, a second baffle plate 804 is further included, and the two ends of the second baffle plate are vertically connected to the outer surfaces of the two second vertical plates 802, and the second baffle plate 804 is integrally formed with the inner frame 8; the second baffle plate 804 is located on the outside of the other end of the suction pump 3.

[0046] The connection points between the second bottom plate 801 and the lower ends of the two second vertical plates 802 extend outwards to form two second connecting plates 805 . The second connecting plates 805 are fixedly connected to the chassis bottom plate 102 .

[0047] From the above description, it can be seen that the shock-absorbing bracket is not directly connected to the suction pump 3. The two end sides of the suction pump 3 are limited only by the two first vertical plates 701 and the second vertical plates 802, and the two ends of the suction pump 3 are axially limited by the first baffle plate 704 and the second baffle plate 804.

[0048] In order to realize the connection between the suction pump 3 and the chassis bottom plate 102, four shock-absorbing connecting columns 10 made of flexible material are further included, and the shock-absorbing connecting columns 10 are respectively vertically connected to the suction pump bottom plate 301 of the suction pump 3 and the chassis bottom plate 102; the suction pump bottom plate 301 is not in contact with the chassis bottom plate 102.

[0049] In this embodiment, the shock-absorbing connecting column 10 is formed in one piece by a lower vertebral body 1001, a lower connecting column 1002, a supporting column 1003, an upper connecting column 1004, an upper vertebral body 1005 and an upper column 1006; the supporting column 1003 is located between the lower connecting column 1002 and the upper connecting column 1004, and the diameter of the supporting column 1003 is larger than that of the lower connecting column 1002 and the upper connecting column 1004; the diameter of the end of the lower vertebral body 1001 connected to the lower connecting column 1002 is larger than that of the lower connecting column 1002; the diameter of the end of the upper vertebral body 1005 connected to the upper connecting column 1004 is larger than that of the upper connecting column 1004. Therefore, an annular groove is formed between the lower vertebral body 1001 and the supporting column 1003, and an annular groove is also formed between the supporting column 1003 and the upper vertebral body 1005.

[0050] The lower connecting column 1002 is inserted into the hole of the chassis bottom plate 102, the upper connecting column 1004 is inserted into the hole of the suction pump bottom plate 301, and the supporting column 1003 is located between the suction pump bottom plate 301 and the chassis bottom plate 102; thus, the suction pump 3 can be suspended on the chassis bottom plate 102 through the shock-absorbing connecting column 10, and when the suction pump 3 is working, the vibration generated is transmitted to the shock-absorbing connecting column 10, and is buffered until it disappears, thereby preventing noise from being generated, and further eliminating the influence of the suction pump 3 built into the host chassis 1 on the host. The thickness of the chassis bottom plate 102 is less than the height of the lower connecting column 1002, and the thickness of the suction pump bottom plate 301 is less than the height of the upper connecting column 1004.

[0051] The diameters of the through holes in the chassis bottom plate 102 and the through holes in the suction pump bottom plate 301 are slightly larger than the diameters of the lower connecting column 1002 and the upper connecting column 1004, but smaller than the diameter of the support column 1003, as well as the diameter of the end where the lower vertebral body 1001 is connected to the lower connecting column 1002 and the diameter of the end where the upper vertebral body 1005 is connected to the upper connecting column 1004, thereby preventing the shock-absorbing connecting column 10 from detaching from the chassis bottom plate 102 and the suction pump bottom plate 301.

[0052] After the shock-absorbing connecting column 10 is assembled with the chassis bottom plate 102 and the suction pump bottom plate 301 , the upper vertebral body 1005 is located above the suction pump bottom plate 301 , and the lower vertebral body 1001 is located outside the chassis bottom plate 102 .

[0053] This embodiment uses four shock-absorbing connecting columns 10, but for those skilled in the art, using two or more of the four shock-absorbing connecting columns 10 and installing them at appropriate positions of the suction pump 3 can keep the suction pump 3 in a stable state. For example, using three or more shock-absorbing connecting columns 10 can achieve basically the same effect as using four shock-absorbing connecting columns 10.

[0054] The suction pump 3 is further provided with a drainage pipe 11 , and the free end of the drainage pipe 11 passes through the chassis bottom plate 102 and is located outside the chassis 1 .

[0055] The suction pump 3 generally adopts a vacuum pump, which is connected to the sewage box 5. After starting, the sewage box 5 is evacuated to form a negative pressure in the sewage box, thereby forming a pressure difference between the sewage box 5 and the human body cavity, thereby extracting waste liquid into the sewage box 5. When the waste liquid in the sewage box 5 is full, the safety switch in the sewage box 5 (that is, the liquid level switch commonly used in the sewage box of existing products) fails, and the waste liquid enters the suction pump through the connecting pipe. At this time, it needs to be discharged outside the chassis 1 through a spare pipe to prevent the waste liquid from entering the chassis 1 and corroding the host. The drain pipe 11 here is a spare pipe. When the waste liquid flows back to the suction pump 3, it is discharged through the drain pipe 11.

[0056] The sewage box 5 is provided with a quick connector 12 for connecting to a pipeline for extracting waste fluid from the human body.

[0057] like Figure 9-11 As shown, in order to realize the quick connection between the sewage box 5 and the host, so as to install and remove the sewage box, the joint 6 includes an outer cylinder 601 fixedly connected to the free end of the connecting pipe, and a hollow plug connector 602 arranged inside the outer cylinder 601 and coaxial with the outer cylinder 601, that is, the outer cylinder 601 and the hollow plug connector 602 are coaxially arranged; the sewage box is provided with a plug-in cylinder 501 detachably connected to the hollow plug connector 602, and the plug-in cylinder 501 is connected to the inside of the sewage box 5; after the hollow plug connector is combined with the plug-in cylinder, the plug-in cylinder is located inside the outer cylinder. The hollow plug connector 602 adopts a common pagoda connector shape.

[0058] The suction pump 3 is integrated in the chassis 1 and when used in the field, such as in a field hospital or a temporary outdoor medical facility, it can be quickly connected to a pipe for extracting waste liquid from the human body through the quick connector 12 on the sewage box 5; at the same time, the suction pump is fixed in the chassis 1 using a shock-absorbing bracket and a shock-absorbing connecting column 10, which can eliminate the vibration and noise generated by the suction pump 3 during operation, thereby reducing the impact of the built-in suction pump 3 on the host; compared with the existing method of separately arranging the host and the suction pump 3, the suction pump 3 of the present invention forms a whole with the host, which is easy to carry and move quickly, and is easy to use.

[0059] In the above description, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or it can be the internal connection of two components.

[0060] Although the present invention has been described by way of embodiments, persons skilled in the art will appreciate that there are many modifications and variations of the present invention without departing from the spirit of the present invention. It is intended that the appended claims include these modifications and variations without departing from the spirit of the present invention.
