Description

TECHNICAL FIELD

[0001] The utility model relates to an anus and intestine tube intubation technical field, concretely relates to an anus and intestine tube intubation assembly. BACKGROUND

[0002] For those who are long-term bedridden due to illness or accident, unconscious patients, nursing work is not only the key to maintain vital signs stable, but also an important guarantee to prevent complications.

[0003] Such patients due to limited physical activity, diet usually through the gastric tube injection liquid food, the waste (or called excrement) after digestion is discharged in a thin paste. This condition brings special challenges to nursing, especially the problem of handling fecal incontinence. If not cleaned up in time, the patient's skin is in contact with excrement for a long time, which can easily lead to incontinence dermatitis, and further cause perianal ulceration, infection, and in the most serious cases, even cause septic shock, posing a threat to the patient's life.

[0004] Research has found that in order to facilitate the drainage of fecal incontinence of patients, medical staff generally use an anus and intestine intubation tube to insert the front end into the anus, then dilute the fecal drainage, and finally drain the feces into a pollution collection bag (or drainage bag). The pollution collection bag is used to collect feces discharged from the body. The pollution collection bag connected at the end of the anus and intestine intubation tube itself has good sealing performance to prevent odor from spreading, and is provided with a discharge port to facilitate regular cleaning.

[0005] However, further research has found that the traditional anus and intestine intubation tube is designed with a trumpet-shaped cross section at the front end (actually a conical head, i.e. a beveled cut). That is, the existing intubation tube adopts a conical body design (the design of the conical head can increase the fixation of the intubation tube in the anus, reduce the possibility of sliding and displacement. At the same time, it ensures sealing: the conical head can help form a better seal to prevent liquid or gas leakage during fecal incontinence drainage, ensuring the effectiveness of the intubation process and liquid drainage; therefore, only a single round head cannot meet the design requirements, and a conical head with a trumpet shape is required), but the diameter of the conical body is large enough to facilitate insertion into the anus and the wrapped intubation body to ensure smooth insertion into the anus. However, the diameter of the end face of the conical body tail is large when it is pulled out of the anus, which can still cause discomfort and further damage to the patient.

[0006] Therefore, there is an urgent need for an improved design of an anus and intestine intubation tube to minimize damage to the muscles at the anus when the intubation body is pulled out while ensuring smooth insertion and smooth liquid drainage operation. UTILITY MODEL CONTENTS

[0017] Preferably, as an implementable solution; the long strip-shaped pull wire constituting the filling layer is a plastic structure strip.

[0018] Preferably, as an implementable solution; the filling layer is in a spiral shape in a natural relaxed state; and the filling layer can be stretched into a long strip-shaped soft plastic structure strip in a stretched state, which will not be repeated here.

[0019] The utility model discloses the beneficial effect is:

[0020] The utility model discloses an anus and enteron pipe intubate subassembly, including intubate body and the pipe head of the head section of sleeve joint installation in intubate body, the end of intubate body is installed with the pollution collection bag, the pipe head includes ellipsoidal type front section and the conical body tail section of with ellipsoidal type front section is connected, the inner layer of conical body tail section is equipped with conical body type cavity, and conical body type cavity inside is provided filling layer, the filling layer is by long strip shape pull wire along conical body type cavity's inside to the outside layer along annular path winding intubate body and forms the conical filling layer of the filling layer,

At this time, the excrement is guided into the drainage bag (or pollution collection bag) to complete the drainage treatment. When the drainage treatment is completed, the conical tail section can be deformed when it is pulled out of the anus. That is, the filling layer as a whole is similar to a pull wire body mechanism to form a conical shape. Therefore, when the pull wire part is pulled outwards, the filling layer of the conical body gradually becomes smaller, the diameter gradually decreases, and finally the conical cavity of the inner layer of the conical tail section is empty to form a hollow, thereby reducing the volume of the conical tail section and reducing the damage to the anus when it is pulled out (specifically, reducing the stimulation to the perianal mucosa and perianal sphincter when it is pulled out).

[0034] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0035] The utility model is described below in combination with a preferred embodiment of the device.

[0036] Embodiment one

[0037] The utility model embodiment one provides a kind of anorectal tube cannula assembly, including cannula body and the pipe head of the head section of cannula body is sleeved and installed, the pipe head includes ellipsoid type front section and the conical tail section connected with the ellipsoid type front section;The inner layer of the conical tail section is equipped with conical cavity, and filling roll layer is arranged inside the conical cavity;The filling roll layer is the conical filling layer formed by the long strip shape wire drawing along the inside of the conical cavity and the outside layer by layer along annular path winding cannula body;

[0038] The stretching end of the outermost layer of the filling roll layer extends the conical tail section and extends the end of the cannula body by preset length and forms wire drawing part.

[0039] As Figures 2-5 The utility model embodiment one provides anorectal cannula by cannula body 1 and pipe head 2 as shown in the figure;Wherein, pipe head 2 includes ellipsoid type front section 21 and the conical tail section 22 connected with front section 21.The end of cannula body 1 is installed with pollution collection bag 3;The inner layer of above-mentioned conical tail section 22 is equipped with conical cavity 221, and filling roll layer 222 is filled in cavity 221. Wherein, one end of above-mentioned filling roll layer 222 extends to the end of cannula body 1 by preset length by wire drawing part 223. Generally, above-mentioned filling roll layer 222 maintains conical shape (spiral shape) in static state;When needing to pull out cannula, wire drawing part 223 is pulled outwards, leading to that filling roll layer 222 gradually reduces, and the diameter of conical tail section 22 gradually reduces, finally makes the inner layer of conical cavity 221 form hollow state, reduces the diameter of cannula head end, thereby reducing the damage to the muscle at anus.

[0040] The utility model discloses an anus catheterization device, which comprises an insertion tube body, a conical tail section and an ellipsoid front section. Figure 8

[0041] In the specific technical scheme, the ellipsoid front section 21 is designed to reduce the direct pressure on the anus muscle during insertion, ensuring the smoothness and safety of the insertion process. The filling layer 222 is used to gradually reduce the diameter of the conical tail section after the pulling of the wire drawing part, eventually forming a hollow conical cavity in the conical tail section.

[0042] It is noted that in the above specific technical scheme, the ellipsoid front section is designed to reduce the direct pressure on the anus muscle during insertion, ensuring the smoothness and safety of the insertion process. The filling layer is similar to a wire drawing mechanism, and after the wire drawing part is pulled outwards, the filling layer of the conical tail section gradually becomes smaller in diameter, eventually forming a hollow conical cavity.

[0043] The technical scheme provided by the utility model embodiment realizes the dynamic reduction of the diameter of the catheter head during the process of pulling out the anus catheter, significantly reduces the damage to the anus muscle, and improves the comfort of the patient and the safety of clinical application.

[0044] In the specific technical scheme, the conical cavity is a conical body of the same proportion as the conical tail section.

[0045] As shown in Figure 6 and Figure 7 , a wire drawing part limiting sliding cavity 11 is provided on the side wall surface of the insertion tube body and located at the rear end of the conical tail section, extending towards the end along the length direction of the insertion tube body; the wire drawing part 223 extends towards the end of the insertion tube body along the inside of the wire drawing part limiting sliding cavity and finally passes out of the wire drawing part limiting sliding cavity 11.

[0046] ​In a further technical solution, the side wall surface of the cannula body is provided with a channel groove along the length direction, and the wire pulling part limiting sliding cavity is recessed in the channel groove, so that the wire pulling part limiting sliding cavity and the outer periphery of the cannula body form a tubular whole, further reducing the damage to the anus and surrounding tissues during pulling out.

[0047] Research shows that the external sphincter muscle surrounds the anus and is composed of striated muscle (voluntary muscle). The external sphincter function mainly includes the following: controlling defecation function: the external sphincter muscle helps to control the time of defecation and air release by contraction and relaxation, so that the patient can consciously decide when to discharge feces and gas. Maintain the function of closing the anus: when not defecating or releasing air, the external sphincter muscle keeps the anus closed to prevent involuntary discharge of feces and gas.

[0048] In order to reduce the damage to the external sphincter muscle at the anus when the wire pulling part is pulled out, a wire pulling part limiting sliding cavity is designed, which can reduce the damage: by setting the wire pulling part limiting sliding cavity, the wire pulling part can be pulled out more smoothly, reducing the friction and pressure on the anal sphincter muscle, thereby reducing the risk of damage and avoiding direct scratching of the muscles around the anus by the outward pulling of the wire pulling part.

[0049] At the same time, the wire pulling part limiting sliding cavity can limit the speed and pulling force of the outward pulling of the wire pulling part: the design of the wire pulling part limiting sliding cavity can also help to control the pulling force of the wire pulling part, avoiding damage to the anal sphincter muscle caused by excessive pulling force. The existence of the wire pulling part limiting sliding cavity makes it easier to pull out the wire pulling part, and medical staff can more easily control the pulling out process of the cannula, improving the convenience and safety of operation.

[0050] In a specific technical solution, the width of the wire pulling part from the head end of the filling roll layer 222 to the outermost layer thereof is gradually increased. In the initial state, the width of the wire pulling part is wider, which facilitates the operator to pinch the wire pulling part with the thumb, and also facilitates the wire pulling part of the tail to wind the outermost layer of the conical filling roll layer. Therefore, the winding radius of the innermost layer of the conical filling roll layer is small, and the radius of the bottom surface of the filling roll layer gradually increases when winding outward, and the winding radius of the outermost layer of the conical filling roll layer is the largest. Therefore, the width of the wire pulling part from the head end of the filling roll layer to the outermost layer thereof is gradually increased, which also meets the winding design requirements of the conical shape.

[0051] In a specific technical solution, the long strip-shaped wire pulling part constituting the filling roll layer 222 is a plastic structure strip.

[0052] The analysis of the above technical scheme shows that the filling roll layer is formed into a final cone by winding the long strip-shaped wire roll; the soft and elastic material can facilitate the deformation of the filling roll layer and reduce friction and compression during the removal of the catheter;

[0053] As shown in Figure 5 , the filling roll layer 222 is in a spiral shape in a natural relaxed state; in a stretched state, it can be stretched into a long strip-shaped soft plastic structure strip, which will not be described again.

[0054] The preferred plastic structure strip as the material of the filling roll layer can maintain its shape in a stretched state, providing better structural stability and durability. This material selection helps to maintain the shape of the cone tail during the use of the catheter. At the same time, in order to facilitate the formation of the cone structure of the filling roll layer, some sterile adhesive liquid can be used to assist the winding and bonding of the above-mentioned plastic structure strip to form the filling roll layer, and the limited amount of sterile adhesive liquid does not affect the pulling out of the plastic structure strip.

[0055] In the above technical scheme, the spiral shape in the natural relaxed state: the filling roll layer is in a spiral shape in a natural state, which helps to keep it compact when the catheter is not stretched, and facilitates filling into the cavity of the cone. At the same time, the spiral shape also helps to maintain the structural integrity of the cone tail in the unstretched state.

[0056] When it is necessary to adjust and reduce the diameter of the catheter head to adapt to the removal, the filling roll layer can be stretched into a long strip-shaped soft plastic structure strip. This design allows the catheter to gradually reduce in diameter during removal, thereby reducing damage to the anal sphincter and providing a smoother removal experience, which can ensure the sealing of the fecal discharge drainage during use, while reducing the irritation of the removal through the design of the deformed diameter.

[0057] Due to the stretchable nature of the filling roll layer, the diameter of the cone tail can be gradually reduced during removal, avoiding sudden changes in diameter that can cause damage to the anal sphincter and reducing the pain and discomfort of the patient.

[0058] In summary, this design of the anorectal catheter uses a plastic structure strip as the filling roll layer, which can maintain a spiral shape in a natural state and become a long strip-shaped structure in a stretched state, effectively reducing damage to the anal sphincter and improving the controllability of the operation and the comfort of the patient, which is an innovative technical solution.

[0059] The anus and intestinal tube intubation assembly provided by the embodiment of the utility model provides more effective nursing means for long-term bedridden and fecal incontinence patients. Firstly, it significantly reduces the skin problems caused by fecal retention, and reduces the incidence of incontinence dermatitis. Secondly, since the device can effectively manage the excrement, the patient can keep clean and dry, and the quality of life is improved. Thirdly, the corresponding structure design can effectively reduce the damage to the anal sphincter when pulling out, and the use experience is improved.

[0060] The basic principle, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model can have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The protection scope required by the utility model is defined by the appended claims and their equivalents.
