Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a suction tube head and a suction device having the same. Background Art

[0002] The suction device is a device used to remove bleeding, exudate, pus, contents of chest organs, etc. during surgery. The use of the suction device can make the surgery clear and reduce the chance of contamination. The principle of the suction device is very simple, that is, to create a negative pressure state of its suction head through a certain method, so that the atmospheric pressure will squeeze the substances outside the suction head into the suction head, thereby achieving the "suction" effect.

[0003] The existing common suction device usually has one or more small holes arranged on the suction device head.

[0004] However, ordinary suction devices can be easily blocked by human tissues due to their single channel, causing "sucking". It is necessary to pause the suction source to clean the suction device, resulting in reduced efficiency of the suction operation. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the problem that the existing suction device is easily "sucked" by human tissue, thereby providing a suction tube head and a suction device having the same.

[0006] In order to solve the above technical problems, the utility model provides a suction pipe head, comprising:

[0007] A tube body having a suction channel coaxially arranged inside;

[0008] A suction hole is provided at the head of the tube body, and the suction hole is communicated with the suction channel;

[0009] A side suction hole is arranged on the side wall of the tube body, and the side suction hole is connected to the suction channel through a side suction channel. The side suction channel is bent on the cross section of the tube body perpendicular to the central axis, and a plurality of side suction channels form a vortex structure around the suction channel.

[0010] Optionally, the side suction hole is configured to be in a long strip shape, and the side suction hole extends along the length direction of the tube body toward a direction away from the suction hole.

[0011] Optionally, four side suction holes are evenly arranged around the circumference of the tube body.

[0012] Optionally, the head of the tube body is arranged as a hemispherical surface, and the suction hole is arranged on the hemispherical surface.

[0013] Optionally, the suction hole comprises:

[0014] A first through hole is arranged at the center of the hemispherical surface, and the first through hole is coaxially arranged with the tube body;

[0015] A plurality of second through holes are arranged on the hemispherical surface around the first through hole.

[0016] Optionally, four second through holes are evenly arranged around the first through hole.

[0017] Optionally, the head of the tube body is further provided with a confluence cavity, and the suction hole, the side suction channel and the suction channel are connected to the confluence cavity.

[0018] The utility model provides a suction device, comprising the suction tube head described in any one of the above schemes.

[0019] The technical solution of the utility model has the following advantages:

[0020] 1. The suction tube head provided by the utility model has the head of the tube body extended into the suction position, and the fluid to be sucked enters the suction channel through the suction hole and the side suction hole, and is transported outward through the suction channel. During use, when the suction hole of the head is blocked, suction can still be performed through the side suction hole, and the side suction channel is bent to prevent debris from entering the suction channel and causing blockage, thereby reducing the probability of the suction device being deflated by human tissue. Multiple side suction channels form a vortex structure, which can form a vortex flow in the circumference of the tube body, thereby improving the suction efficiency. The suction tube head provided by the utility model solves the problem in the prior art that the suction device is easily "sucked deflated" by human tissue.

[0021] 2. The suction tube head provided by the utility model has a side suction hole extending along the length direction of the tube body in a direction away from the suction hole, so that the length of the side suction hole is longer, which can reduce the probability of the side suction hole being blocked and reduce the probability of the suction device being sucked flat by human tissue.

[0022] 3. The suction tube head provided by the utility model has a tube body which is a circular tube. The four side suction holes evenly arranged around the tube body face different directions, which can avoid the four side suction holes being blocked at the same time. The four side suction holes are evenly arranged around the circumference of the tube body. When one of the side suction holes is blocked, suction can still be performed through the other side suction holes, which can reduce the probability of the suction device being sucked deflated by human tissue.

[0023] 4. The suction tube head provided by the utility model has a relatively smooth hemispherical surface, which can prevent the head of the tube body from causing damage to human tissue.

[0024] 5. The suction tube head provided by the utility model can perform suction through the second through holes surrounding the first through hole in the circumference of the first through hole when the first through hole is blocked, thereby reducing the probability of the suction device being deflated by human tissue.

[0025] 6. The suction tube head provided by the utility model has four second through holes evenly arranged around the first through hole, which can face different directions on the hemispherical surface, thereby reducing the probability of the four second through holes being blocked at the same time and reducing the probability of the suction device being deflated by human tissue.

[0026] 7. The suction pipe head provided by the utility model, the suction fluid entering through the suction hole and the side suction channel is collected in the confluence cavity, and then transported outward through the suction channel.

[0035] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0039] This embodiment provides a suction tube head structure that can reduce the probability of being deflated by human tissue, and is used to remove bleeding, exudate, pus, contents of chest organs, and other substances during surgery.

[0040] like Figure 1-3 As shown, a specific implementation of a suction pipe head provided in this embodiment includes: a pipe body 1, a suction hole 3 and a side suction hole 4; a suction channel 2 is coaxially arranged inside the pipe body 1; the suction hole 3 is arranged at the head of the pipe body 1, and the suction hole 3 is connected with the suction channel 2; the side suction hole 4 is arranged on the side wall of the pipe body 1, and the side suction hole 4 is connected with the suction channel 2 through the side suction channel 5, and the side suction channel 5 is bent on the cross section of the pipe body 1 perpendicular to the central axis, and a plurality of the side suction channels 5 form a vortex structure around the suction channel 2.

[0041] When in use, the head of the tube body 1 extends into the suction position, and the suction fluid enters the suction channel 2 through the suction hole 3 and the side suction hole 4, and is transported outward through the suction channel 2. During use, when the suction hole 3 of the head is blocked, suction can still be performed through the side suction hole 4, and the side suction channel 5 is bent to prevent debris from entering the suction channel 2 and causing blockage, thereby reducing the probability of the suction device being deflated by human tissue. The multiple side suction channels 5 form a vortex structure, which can form a vortex flow in the circumference of the tube body 1, thereby improving the suction efficiency. The suction tube head provided in this embodiment solves the problem in the prior art that the suction device is easily "sucked deflated" by human tissue.

[0042] like Figure 1 As shown, in the suction tube head provided in this embodiment, the side suction hole 4 is set to be a long strip, and the side suction hole 4 extends along the length direction of the tube body 1 in a direction away from the suction hole 3. The long strip-shaped side suction hole 4 is longer, which can reduce the probability of the side suction hole 4 being blocked, thereby reducing the probability of the suction device being deflated by human tissue. In addition, as an alternative embodiment, the side suction hole 4 can also be set to a round hole, and a plurality of the side suction holes 4 are set along the length direction of the tube body 1.

[0043] like Figure 1-3 As shown, in the suction tube head provided in this embodiment, four side suction holes 4 are evenly arranged around the circumference of the tube body 1. The tube body 1 is a circular tube, and the four side suction holes 4 evenly arranged around the tube body 1 face different directions, which can prevent the four side suction holes 4 from being blocked at the same time. When one of the side suction holes 4 is blocked, suction can still be performed through the other side suction holes 4, which can reduce the probability of the suction device being deflated by human tissue. In addition, as an alternative embodiment, the number and position of the side suction holes 4 set on the side wall of the tube body 1 can be adjusted according to design requirements.

[0044] like Figure 1 As shown, in the suction tube head provided in this embodiment, the head of the tube body 1 is set as a hemispherical surface, and the suction hole 3 is set on the hemispherical surface. The hemispherical surface is relatively smooth, which can prevent the head of the tube body 1 from causing damage to human tissue. In addition, as an alternative embodiment, the head of the tube body 1 can also be set as a plane.

[0045] like Figure 1 , Figure 4As shown, in the suction tube head provided in this embodiment, the suction hole 3 includes: a first through hole 31, which is arranged at the center of the hemispherical surface, and the first through hole 31 is coaxially arranged with the tube body 1; and a plurality of second through holes 32 are arranged around the first through hole 31 on the hemispherical surface. When the first through hole 31 is blocked, suction can be performed through the second through holes 32 surrounding the first through hole 31, thereby reducing the probability of the suction device being deflated by human tissue. In addition, as an alternative embodiment, the suction hole 3 can also be provided with only the first through hole 31, or only the second through hole 32.

[0046] like Figure 1 , Figure 4 As shown, in the suction tube head provided in this embodiment, four second through holes 32 are evenly arranged around the first through hole 31. The four second through holes 32 are evenly arranged around the first through hole 31, and can face different directions on the hemispherical surface, thereby reducing the probability of the four second through holes 32 being blocked at the same time and reducing the probability of the suction device being deflated by human tissue. In addition, as an alternative embodiment, the number and position of the second through holes 32 on the hemispherical surface can be adjusted according to design requirements.

[0047] like Figure 2 As shown, in the suction pipe head provided in this embodiment, the head of the pipe body 1 is also provided with a confluence cavity 6, and the suction hole 3, the side suction channel 5 and the suction channel 2 are connected with the confluence cavity 6. The suction fluid entering through the suction hole 3 and the side suction channel 5 is collected in the confluence cavity 6 and then transported outward through the suction channel 2. In addition, as an alternative embodiment, the confluence cavity 6 can be omitted, and a plurality of connecting holes are provided on the side wall of the suction hole 3, and the side suction channel 5 is connected with the suction channel 2 through the connecting holes.

[0050] In addition, this embodiment also provides an aspirator, which uses the aspiration tube head described in the above embodiment to achieve the suction of bleeding, exudate, pus, contents of chest organs and other substances during surgery.

[0051] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
