Description

Technical Field

[0001] The present invention relates to the technical field of intestinal ventilation and defecation, and in particular to a negative pressure drainage system for intestinal ventilation and defecation. Background Art

[0002] In clinical intestinal ventilation and defecation treatment, the drainage system is a key device to ensure patient comfort and treatment effect. The insertion part of existing devices is mostly a single fixed form. If a sharp or hard structure is used for easy insertion, it will lead to poor drainage during drainage; if a thicker or outward-expanding structure is used to improve the drainage fit, the insertion process will be difficult and easily cause strong discomfort to the patient. At the same time, during drainage, the drainage is often not tightly fitted with the inner wall of the intestine, resulting in residual excrement, affecting the drainage effect; The fixing methods of existing devices are mostly relatively simple, and most of them rely solely on tape. It is difficult to ensure the stability of the drainage tube, and it is very easy to shift, resulting in frequent leakage of excrement. This not only increases the workload of nursing staff, but also easily causes adverse consequences such as skin infection and bed unit contamination in patients.

[0003] Existing drainage systems rely on natural drainage and lack effective negative pressure devices, resulting in slow and incomplete drainage. This makes it difficult to meet treatment needs, especially for patients with weak intestinal function. Furthermore, the gases generated during drainage are directly discharged into the air, containing odors and pathogens that can easily cause air pollution and pose a potential threat to the health of medical staff and patients.

[0004] In order to solve the above problems, the present invention provides a negative pressure drainage system for intestinal ventilation and defecation. Summary of the Invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a negative pressure drainage system for intestinal ventilation and defecation, wherein the insertion portion has at least two form conversions, which are convenient for insertion in the first form and convenient for drainage in the second form.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a negative pressure drainage system for intestinal ventilation and defecation, comprising: A collection frame, wherein the collection frame is provided with a discharge inlet; a drainage tube, the drainage tube being in communication with the discharge port on the collection frame; An inserting portion, the inserting portion being fixedly mounted on an end of the drainage tube away from the collecting frame; The inserting portion has at least two forms: When the insertion portion is in the first configuration before being inserted into the patient's body, the end of the insertion portion away from the drainage tube is in an inwardly retracted conical shape; When the insertion portion is inserted into the patient's body, it is in the second configuration, where the end of the insertion portion away from the drainage tube is in an outwardly expanding trumpet shape.

[0007] Preferably, a fixed sac is provided on the outer side of one end of the drainage tube close to the insertion part, an air inlet pipe is installed on the fixed sac, and a sealing clamp is installed on the air inlet pipe. Air can be inflated into the interior of the fixed sac through the air inlet pipe. During inflation, the sealing clamp does not apply pressure to the air inlet pipe, so that the air inlet pipe remains unobstructed. After inflation is completed, the sealing clamp applies pressure to the air inlet pipe, so that the air inlet pipe remains sealed to avoid air leakage.

[0008] Preferably, the inserting portion comprises: Multiple spring plates, the multiple spring plates are fixedly connected to one end of the drainage tube away from the collection frame, and the multiple spring plates are distributed along the circumference of the drainage tube, and the material of the spring plates is medical elastic silicone; A plurality of expansion bladders are staggeredly distributed with a plurality of spring plates, and the expansion bladders are fixedly connected to the corresponding spring plates. The expansion bladders are communicated with the fixed bladders, and an expansion bladder is provided between every two adjacent spring plates.

[0009] Preferably, a plurality of reinforcement rings are fixedly mounted on the inner side surface of the expansion bladder to limit the expansion direction of the expansion bladder.

[0010] Preferably, an expansion portion is provided between the fixed sac and the insertion portion, the expansion portion being in communication with the expansion sac and the fixed sac, and when air is inflated into the interior of the fixed sac, the expansion portion expands into a convex ring shape.

[0011] Preferably, the expansion portion comprises: an annular groove, the annular groove being provided on the circumferential surface of the drainage tube; The expansion ring is fixedly installed between the groove walls on both sides of the ring groove, and the outer circumferential surface of the expansion ring is flush with the outer circumferential surface of the drainage tube.

[0012] Preferably, a plug-in tube aligned with the discharge inlet is fixedly connected to the upper side of the collection frame, and the drainage tube is plugged into the plug-in tube.

[0013] Preferably, a plurality of convex rings are fixedly connected to the inner annular surface of the plug-in tube, and a plurality of grooves adapted to the convex rings are provided on the drainage tube.

[0014] Preferably, the collection frame is provided with an exhaust pipe, and the exhaust pipe is connected to an external negative pressure device.

[0015] Preferably, a filter element is installed inside the exhaust pipe.

[0016] The beneficial effects of the present invention are: The present invention realizes the conversion of the insertion part into at least two forms through the arrangement of an expansion sac and multiple spring plates. The first form is an inward-retracted cone, which can greatly reduce the resistance during insertion into the patient's body, alleviate the patient's pain and the risk of intestinal damage; the second form is an outward-expanding trumpet shape, which can fit tightly to the inner wall of the intestine, greatly improving the smoothness and thoroughness of drainage, and effectively avoiding excrement residue.

[0017] The present invention realizes that after inflation, the fixed sac expands and fits tightly against the patient's buttocks through the arrangement of the expansion ring and the fixed sac, and the expansion ring also expands into a convex ring shape, thereby enabling the drainage tube to be better maintained and effectively preventing excrement leakage and pollution.

[0018] The present invention realizes that the interior of the collection frame is always kept in a negative pressure state by arranging the exhaust pipe and the filter element, thereby better performing the drainage work and preventing the air from being directly discharged and causing air pollution.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The present invention provides a negative pressure drainage system for intestinal ventilation and defecation, such as Figures 1 to 7 shown.

[0030] Example 1: A negative pressure drainage system for intestinal ventilation and defecation includes a collection frame 1, which is provided with a discharge port for connecting to a drainage tube 2. The drainage tube 2 is in communication with the discharge port on the collection frame 1, and an insertion portion is fixedly mounted on the end of the drainage tube 2 away from the collection frame 1. The insertion portion has at least two forms. When the insertion portion is in a first form, it is conical, and the diameter of the end away from the drainage tube 2 is smaller than the diameter of the end near the drainage tube 2, which can be easily inserted into the patient's body. When the insertion portion is in a second form, it is an outwardly flared trumpet shape, and the diameter of the end away from the drainage tube 2 is larger than the diameter of the end near the drainage tube 2, which facilitates drainage. After insertion into the patient's body, the insertion portion can be controlled to switch from the first form to the second form.

[0031] The insertion part includes multiple spring plates 4 and multiple expansion sacs 5. The multiple spring plates 4 are fixedly connected to the end of the drainage tube 2 away from the collection frame 1 and are distributed along the circumference of the drainage tube 2; the multiple expansion sacs 5 and the multiple spring plates 4 are staggered, that is, an expansion sac 5 is provided between every two adjacent spring plates 4, and the expansion sacs 5 are fixedly connected to the corresponding spring plates 4.

[0032] A plurality of reinforcing rings 6 are fixedly mounted on the inner side of the expansion bladder 5 to limit the expansion direction of the expansion bladder 5. The arrangement of the reinforcing rings 6 allows the expansion bladder 5 to only move in the direction of the expansion bladder 5 during expansion. Figure 7 The expansion direction of the arrow shown in FIG. 1 is to ensure smooth expansion of the insertion portion. The shape of the expansion capsule 5 is thin at one end and thick at the other end (as shown in FIG. Figure 6 and Figure 7 As shown in the figure, the thickness of the end close to the drainage tube 2 is smaller than the thickness of the end away from the drainage tube 2, so that when the expansion bladder 5 is inflated, the end of the spring plate 4 away from the drainage tube 2 can move smoothly toward the axial direction away from the drainage tube 2, so that the insertion portion is converted into the second form.

[0033] In the initial state, the expansion bladder 5 is not inflated. Under the elastic force of the spring plate 4, the insertion portion is in the first form, that is, the end away from the drainage tube 2 is an inward-retracted cone. At this time, inserting the insertion portion into the patient's body can greatly reduce the insertion resistance.

[0034] After insertion, the expansion bladder 5 is inflated, driving the spring plate 4 connected thereto to expand outward, so that the insertion portion is converted into a second form, that is, the end away from the drainage tube 2 is an outward-expanding trumpet shape, which fits the inner wall of the intestine and facilitates drainage.

[0035] By controlling the expansion of the expansion bladder 5, the insertion portion can be controlled to switch between the first form and the second form, thereby facilitating insertion into the patient's body and facilitating drainage.

[0036] Example 2: On the basis of Example 1, in order to keep the drainage tube 2 stable during the drainage process, a fixed sac 3 is provided on the outer side of one end of the drainage tube 2 close to the insertion part, and an expansion part is provided between the fixed sac 3 and the insertion part. The expansion part includes an annular groove 7 and an expansion ring 8. The annular groove 7 is provided on the circumferential surface of the drainage tube 2. The expansion ring 8 is fixedly installed between the two side groove walls of the annular groove 7, and the outer circumferential surface of the expansion ring 8 is flush with the outer side circumferential surface of the drainage tube 2. The expansion part is communicated with the expansion sac 5 and the fixed sac 3. When inserted, the expansion ring 8 is located in the patient's intestine.

[0037] An air inlet pipe is installed on the fixed sac 3, and a sealing clamp is provided on the air inlet pipe. Air can be inflated into the interior of the fixed sac 3, the annular groove 7 and the expansion sac 5 through the air inlet pipe, so that the fixed sac 3, the expansion sac 5 and the expansion ring 8 can be expanded. The sealing clamp is a prior art, so it will not be described in detail in this invention (for example, the sealing clamp on the infusion tube).

[0038] After being inflated, the expansion sac 5 expands, causing the insertion part to be converted into the second form, fitting the inner wall of the patient's intestine. The fixed sac 3 is inflated and expands to fit tightly against the patient's buttocks. The expansion ring 8 is inflated and expands into a convex ring shape, which also fits the inner wall of the patient's intestine. The three work together to keep the drainage tube 2 stable and prevent leakage of excrement.

[0039] Example 3: On the basis of Example 2, in order to avoid contamination by the drained excrement, a plug-in tube 9 and an exhaust tube 12 are fixedly provided on the upper side of the collection frame 1. The plug-in tube 9 is aligned with the discharge inlet on the collection frame 1, and the discharge inlet on the collection frame 1 is connected to the drainage tube 2 through the plug-in tube 9. The inner ring surface of the plug-in tube 9 is fixedly connected with multiple convex rings 10, and the drainage tube 2 is provided with multiple card grooves 11 adapted to the convex rings 10. The convex rings 10 are snapped into the card grooves 11 to achieve a firm connection between the drainage tube 2 and the plug-in tube 9.

[0040] The exhaust pipe 12 is connected to the external negative pressure equipment, so that the interior of the collection frame 1 can always maintain a micro-negative pressure state, thereby better achieving drainage. At the same time, a filter element 13 is set inside the exhaust pipe 12 to filter the extracted air to avoid pollution.

[0041] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
