Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a high-position intermuscular abscess drainage and flushing device. Background Art

[0002] A high intermuscular abscess refers to an abscess located in the upper part of the intermuscular space between the internal and external anal sphincters, between the longitudinal muscle of the rectum and the circular muscle, and above the levator ani muscle. The principle of treatment is to incise the abscess and drain the pus. The surgical procedure is: 1. Anesthesia; 2. Incise the skin and subcutaneous tissue, and use hemostatic forceps to separate the muscle layer at the weak muscle to reach the abscess cavity; 3. Insert a drainage tube with a hole on the side wall of the front section to drain the pus. When the pus is thick and / or cannot flow out automatically due to body position reasons, the outer end of the drainage tube can be connected to a suction syringe.

[0003] The existing drainage tube is just a linear hose, and drainage and / or extraction using it may not be thorough. When the pus is thick or difficult to flow out, residual pus is likely to exist, and the probability of disease recurrence is still relatively high. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a high-position intermuscular abscess drainage and flushing device, so as to overcome the problems that the existing drainage tubes cannot completely drain pus and the probability of disease recurrence is slightly higher.

[0005] The utility model solves the technical problem by adopting a technical solution: a high-position intermuscular abscess drainage and flushing device, comprising an inner T-tube and an outer T-tube;

[0006] The inner T-tube comprises an upper transverse tube and a first lower vertical tube arranged in a T-shape, wherein the upper end of the first lower vertical tube is connected with the upper transverse tube at the middle of the upper transverse tube;

[0007] The outer T-tube comprises a half-tube groove and a second lower vertical tube arranged in a T shape, wherein the half-tube groove has a concave cavity, the opening of the concave cavity faces away from the second lower vertical tube, and the upper end of the second lower vertical tube is connected with the concave cavity in the middle of the half-tube groove;

[0008] The first lower vertical tube is inserted into the second lower vertical tube from top to bottom and extends from the lower end of the second lower vertical tube. The gap between the inner wall of the second lower vertical tube and the outer wall of the first lower vertical tube is the second liquid outlet channel.

[0009] At least a part of the upper transverse tube is located in the concave cavity, and the gap between the inner wall of the half-tube groove and the outer wall of the upper transverse tube is the first liquid outlet channel;

[0010] A plurality of liquid outlet holes are arranged on the tube body of the upper horizontal tube;

[0011] The flushing liquid is injected from the lower end of the first lower vertical tube and then enters the abscess cavity from the tube openings at both ends of the upper horizontal tube and the liquid outlet hole. The liquid in the abscess cavity flows out through the first liquid outlet channel and the second liquid outlet channel in sequence.

[0012] Specifically, the inner T-tube is a soft integrated structure.

[0013] Specifically, the outer T-tube is a soft integrated structure.

[0014] Specifically, the cross section of the half-pipe groove is C-shaped.

[0015] Specifically, the axis of the upper transverse tube is consistent with the axis of the half-tube groove.

[0016] Specifically, in order to make it easier for the flushing device to extend into the intermuscular space between the internal and external sphincters, according to the annular shape of the intermuscular space, the axes of the upper horizontal tube and the half-tube groove are arcs, the axis of the first lower vertical tube is perpendicular to the plane where the axis of the upper horizontal tube is located, and the axis of the second lower vertical tube is perpendicular to the plane where the axis of the half-tube groove is located.

[0017] Specifically, a marking line is provided on the outer wall of the first lower vertical tube. When the marking line corresponds to the lower end of the second lower vertical tube, there is a gap between the upper horizontal tube and the half-tube groove to form the first liquid outlet channel. The main function of the marking line is to make the gaps at various locations on the first liquid outlet channel uniform after artificial correspondence.

[0018] Specifically, in order to increase the flushing effect and extend the path through which the flushing liquid flows as much as possible, the liquid outlet holes are arranged on the tube body above the upper transverse tube along the length direction of the upper transverse tube.

[0019] Specifically, in order to make the gap between the first liquid outlet channel and the second liquid outlet channel uniform, positioning protrusions are distributed on the outer wall of the inner T-tube to prevent the outer wall of the inner T-tube from fitting with the inner wall of the outer T-tube. The positioning protrusions are equivalent to suspending the inner T-tube on the outer T-tube.

[0020] The beneficial effects of the utility model are as follows: the high-position intermuscular abscess drainage and flushing device of the utility model is provided with an inner T-tube and an outer T-tube, flushing liquid is injected into the inner T-tube, pus and a mixture of pus and flushing liquid flow out from the gap between the inner T-tube and the outer T-tube, and has the function of drainage and flushing at the same time, so that pus drainage is more thorough, and the probability of disease recurrence is reduced. The inner T-tube can be left in place for a period of time after surgery to more thoroughly drain the residual liquid. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0033] The following descriptions of “upper” and “lower” in terms of positional relationships are based on the attached Figure 1 The display is defined to illustrate the product structure. The product may be turned over as a whole during actual use.

[0034] Attached Figure 1 The invention discloses a high-position intermuscular abscess drainage and flushing device, comprising an inner T-tube 1 and an outer T-tube 2; the inner T-tube 1 comprises an upper transverse tube 1-1 and a first lower vertical tube 1-2 arranged in a T shape, the upper end of the first lower vertical tube 1-2 is connected with the upper transverse tube 1-1 at the middle of the upper transverse tube 1-1; the outer T-tube 2 comprises a half-tube groove 2-1 and a second lower vertical tube 2-2 arranged in a T shape, the half-tube groove 2-1 has a concave cavity 2-1-1, the opening of the concave cavity 2-1-1 faces away from the second lower vertical tube 2-2, the upper end of the second lower vertical tube 2-2 is connected with the concave cavity 2-1-1 at the middle of the half-tube groove 2-1, the inner T-tube 1 and the outer T-tube 2 are respectively as shown in the attached drawings. Figure 4 and attached Figure 5 The half-tube groove 2-1 is equivalent to a groove body formed by cutting off half, most of the tube, or a small part of the tube body in the same direction as the axial direction. The half-tube groove 2-1 in the attached figure is equivalent to a groove body obtained by cutting off half of a circular tube along the axis, and the cross-section of the half-tube groove 2-1 is C-shaped; the half-tube groove 2-1 can also be equivalent to a groove body obtained by cutting off part of an oblate tube, an elliptical tube, or a rectangular tube in the same direction as the axial direction.

[0035] Combined with Figure 2 As shown, the first lower vertical tube 1-2 is inserted into the second lower vertical tube 2-2 from top to bottom and extends from the lower end of the second lower vertical tube 2-2. The gap between the inner wall of the second lower vertical tube 2-2 and the outer wall of the first lower vertical tube 1-2 is the second liquid outlet channel 3; a part of the upper horizontal tube 1-1 is located in the concave cavity 2-1-1, and the gap between the inner wall of the half-tube groove 2-1 and the outer wall of the upper horizontal tube 1-1 is the first liquid outlet channel 4;

[0036] A plurality of liquid outlet holes 1-1-1 are arranged on the tube body of the upper transverse tube 1-1. The liquid outlet holes 1-1-1 are arranged on the tube body above the upper transverse tube 1-1 along the length direction of the upper transverse tube 1-1.

[0037] The flushing liquid is injected from the lower end of the first lower vertical tube 1-2 and then enters the abscess cavity from the tube openings at both ends of the upper horizontal tube 1-1 and the liquid outlet 1-1-1. The liquid in the abscess cavity flows out through the first liquid outlet channel 4 and the second liquid outlet channel 3 in turn.

[0038] The inner T-tube 1 and the outer T-tube 2 are both soft integrated structures, and the material is the same as that of the existing infusion tube.

[0039] The axis of the upper cross tube 1-1 is consistent with the axis of the half-tube groove 2-1. The axes of the upper cross tube 1-1 and the half-tube groove 2-1 are both arcs. Figure 3 As shown, the axis of the first lower vertical tube 1-2 is perpendicular to the plane where the axis of the upper cross tube 1-1 is located, and the axis of the second lower vertical tube 2-2 is perpendicular to the plane where the axis of the half-tube groove 2-1 is located, that is, the axes of the upper cross tube 1-1 and the half-tube groove 2-1 are on the same plane, and the axis of the first lower vertical tube 1-2 is collinear with the axis of the second lower vertical tube 2-2.

[0040] A marking line 1-2-1 is provided on the outer wall of the first lower vertical tube 1-2. When the marking line 1-2-1 corresponds to the lower end of the second lower vertical tube 2-2, there is a gap between the upper horizontal tube 1-1 and the half-tube groove 2-1 to form a first liquid outlet channel 4.

[0041] A better structure of inner T tube 1 is as shown in the attached Figure 6 Positioning protrusions 1-3 are distributed on the outer wall of the inner T-tube 1 to prevent the outer wall of the inner T-tube 1 from fitting with the inner wall of the outer T-tube 2. The number of the dispersed positioning protrusions 1-3 is preferably such that the influence on the flow of the liquid is minimized.

[0042] When the utility model is in use, first connect the lower end of the first lower vertical tube 1-2 to a syringe filled with a flushing solution through a tee tube. Then, push the upper horizontal tube 1-1 and the half tube groove 2-1 horizontally into the intermuscular space as the front part. Since the lower end of the first lower vertical tube 1-2 is blocked, the initial pus can only flow out through the first liquid outlet channel 4 and the second liquid outlet channel 3. When the amount of pus flowing out significantly decreases or it cannot flow out due to its thickness, push the syringe to inject the flushing solution into the pus cavity for flushing, and the mixed solution still flows out through the first liquid outlet channel 4 and the second liquid outlet channel 3. When the internal T-tube 1 is left in place, remove the syringe, and the exuded residual liquid drains out through the internal T-tube 1. At this time, the two ends of the upper horizontal tube 1-1 and the liquid outlet holes 1-1-1 become the inlets for the residual liquid.

[0043] Inspired by the ideal embodiments of the present utility model described above, through the above description, relevant staff can completely make various changes and modifications within the scope not deviating from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
