Description

Technical Field

[0001] The utility model relates to the technical field of intestinal inspection instruments, in particular to a children's enema contrast inspection auxiliary device and a children's enema contrast inspection device. Background Art

[0002] When inspecting or treating the intestines of children, for example, under X-ray, contrast agents are injected into the intestines of children or air enema is performed to reposition intussusception. The catheter needs to be inserted into the intestines through the anus, and contrast agents or gas and other fillers are injected into the intestines through a delivery device to fill the intestines for easy observation of the situation in the intestinal cavity. However, since it is inconvenient or unnecessary to empty the intestines of children by means of enema, when performing enema contrast examination on children, especially younger children, during the process of injecting contrast agents or gas and other fillers into the intestines, the excrement in the intestines, the injected contrast agents and / or gas are very easy to be discharged from the anus, and medical staff need to continue to inject contrast agents or gas into the intestines. Repeated operations not only increase the discomfort of the children undergoing the examination, but also increase the difficulty of operation for medical staff. In addition, the examination or treatment time will be increased, thereby increasing the radiation dose of the child under X-ray. Utility Model Content

[0043] The inventor of the present application has found through a lot of practical experience that when contrast agents or gas are filled into the intestines of children, the intestines of the children are stimulated to excrete because the process is uncomfortable and the infants are young and have low cooperation. At this time, fillers such as air or contrast agents will be discharged along with the excrement. Usually, enema contrast is performed on children under X-rays to treat the intestines of children, such as intussusception, or to observe the condition of the intestinal wall. Since the children cannot control the closure of the anus well, fillers such as air or contrast agents are repeatedly discharged, which not only requires repeated input of air or contrast agents into the intestines of the children, but also increases the practice of the children's X-ray fluoroscopy, increasing the radiation dose.

[0044] In order to prevent the above problems from occurring, the inventors have tried a variety of methods. For example, the front end of the catheter inserted into the anus has an inflatable bubble. When inputting fillers into the intestines of the child, the bubble at the front end of the catheter is first inflated to fit the intestinal wall, and the bubble is kept as close to the anus as possible to assist the child in blocking the anus from inside the anus. At the same time, toilet paper or soft and absorbent materials are used to block the anus from outside to prevent the filler from leaking from the anus. However, due to the young age of the child and the high degree of non-cooperation, although the above measures have been taken, the effect is not good and the filler will still leak out. The inventors also tried to put a flat, circular or elliptical auxiliary blocking piece on the catheter, but due to the obstruction of the buttocks on both sides of the anus, the blocking effect of the auxiliary blocking piece was also not good. After many attempts, the inventor obtained the following embodiment, in which a soft and water-absorbent child enema contrast examination auxiliary device that better fits the shape of the anus and the buttocks around the anus is movably mounted on the catheter. When a filler is introduced into the intestine of the child, the child enema contrast examination auxiliary device is moved to block the anus. Since the shape of the child enema contrast examination auxiliary device is similar to the shape of the child's anus and the buttocks around the anus, and it is soft and plastic, it can achieve a good fit, that is, a good blocking effect, and ensure the comfort of the child during the blocking process. In addition, the excrement leaked from the anus of the child can be absorbed by the child enema contrast examination auxiliary device, so it will not contaminate the equipment or the hands of medical staff.

[0045] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0049] like Figure 1 to Figure 3 As shown, this embodiment provides a pediatric enema contrast examination device, which is used to fill the intestines of children with gas or contrast agents to treat or examine the intestines of children under X-rays. The pediatric enema contrast examination device of this embodiment includes a catheter 20, one end of the catheter 20 is an operating end 21 and the other end opposite to it is an insertion end 22, the insertion end 22 has an inflatable airbag 222 and a through hole 221 located on the side of the airbag 222 away from the insertion end 22, the operating end 21 has a filling channel 214 connected to the through hole 221, and an air supply channel 213 connected to the airbag 222. When performing enema on a child, the insertion end 22 can be inserted into the intestinal tract from the patient's anus, and gas or liquid can be input into the airbag 222 through the gas delivery channel 213 of the operating end 21 to expand the airbag 222 to abut against the intestinal wall, thereby limiting the position of the insertion end 22 in the intestinal tract of the child, preventing the insertion end 22 from falling off from the anus of the child, and at the same time having a certain effect of blocking the intestinal tract of the child to prevent gas or fillers such as contrast agents from leaving from the anus. Then, fillers such as gas or contrast agents are input into the filler channel 214 of the operating end 21, and the fillers enter the intestinal tract of the child from the perforation hole 221.

[0050] In order to allow the insertion end 22 to be smoothly inserted into the intestine and to alleviate the discomfort of the insertion end 22 when being inserted from the anus and when the insertion end 22 is inserted into the intestine, as Figure 1 to Figure 3 As shown, in some embodiments of the present application, the tip 223 of the insertion end 22 is in a smooth arc shape.

[0051] In order to allow the gas or contrast agent or other fillers coming out of the perforation holes 221 to be evenly filled into the intestine, in some embodiments of the present application, there are at least two perforation holes 221, and at least two perforation holes 221 are evenly spaced on the tube wall around the insertion end 22, so that the gas or contrast agent or other fillers can evenly enter the intestine of the child from the perforation holes 221, thereby ensuring a good filling effect.

[0052] In some embodiments of the present application, the catheter 20 has two pipelines, namely a positioning gas delivery pipeline 211 and a filling delivery pipeline 212 , and the two pipelines do not affect each other.

[0053] In order to make the volume of the catheter 20 more compact, in other embodiments of the present application, as Figure 1 to Figure 3 As shown, for the convenience of operation, the operating end 21 is divided into a positioning gas delivery tube 211 and a filling delivery tube 212, the positioning gas delivery tube 211 is connected with the air bag 222 to form a gas delivery channel 213, and the filling delivery tube 212 is connected with the outlet hole 221 to form a filling channel 214. The gas delivery channel 213 and the filling channel 214 are integrated into one at the middle and the insertion end 22. Not only does it make the structure of the entire catheter 20 simpler, but it can also make the diameter of the catheter 20 smaller, the patient's discomfort during the process of passing through the anus and the intestine is less, and the patient's good experience is increased.

[0054] In order to solve the problem of preventing the contrast agent or other filling materials from being injected into the intestine or leaking out of the anus with excrement during enema contrast examination of children, in some embodiments of the present application, such as Figure 1 , Figure 4 As shown, the child enema contrast examination device also includes a child enema contrast examination auxiliary device 10, which includes a blocking member 11, one side of the blocking member 11 is a blocking side 111, and the other side opposite is a supporting side 112, and the blocking side 111 can abut against the anus and block the anus. Specifically, the blocking side 111 is provided with a protrusion, and along the width direction of the blocking side 111, the two sides of the protrusion are arc-shaped and inclined downward and outward, and in the process of blocking the anus, it can fit well with the anus and the buttocks around the anus to obtain a good blocking effect and prevent gas and excrement from being discharged from the anus. Preferably, the blocking side 111 conforms to the shape of the anus and the buttocks around the anus, and the blocking member 11 is provided with a tube inlet hole 113 that penetrates the protrusion. The tube inlet hole 113 is used to pass the catheter 20. After the insertion end 22 of the catheter 20 is inserted into the patient's anus, the medical staff can apply abutting force to the blocking side 111 through the supporting side 112, so that the blocking member 11 can better block the anus.

[0055] Specifically, in some embodiments of the present application, Figure 4-5As shown, the blocking side 111 includes a blocking portion 1111 and buttocks 1112 on both sides of the blocking portion 1111, corresponding to the dividing line between the anus and the buttocks on both sides of the anus, and there is a boundary line between the blocking portion 1111 and the buttocks 1112, and the buttocks 1112 are evenly inclined downward and outward in an arc shape from the boundary lines on both sides of the blocking portion 1111 toward the direction away from the blocking side 111, and the arc shape is an arc shape close to the curve of the human buttocks. The blocking portion 1111 is the above-mentioned protrusion, and the protrusion can be a plane to abut against the anus and block the anus, thereby ensuring that the blocking side 111 can better achieve the effect of blocking the anus.

[0056] Please refer to Figure 6 or Figure 7 Along the length direction of the blocking member 11 or along the width direction of 1, the blocking portion 1111 is ridge-shaped, so that the shape of the blocking side 111 is more closely matched with the shape of the anus and the buttocks around the anus, making it easy for the blocking portion 1111 to be located between the two buttocks and abut against the anus, thereby ensuring a good blocking effect.

[0057] Furthermore, along the length direction of the blocking member 11, the two ends of the blocking portion 1111 are wide and the middle part is narrow, so that the portion where the blocking portion 1111 abuts against the anus is the most protruding portion compared to the surrounding side. In other words, at this time, the blocking portion 1111 is similar to the shape of a volcano, which facilitates the alignment of the blocking portion 1111 with the anus, and when the buttocks 1112 is well fitted with the buttocks, the blocking portion 1111 needs to have a certain amount of compression, and there is a certain relative force between the anus and the blocking portion 1111, thereby ensuring a good sealing effect.

[0058] For more information, see Figure 4 and Figure 7 In some embodiments of the present application, along the length direction of the blocking member 11, the central part of the blocking portion 1111, that is, the part that contacts the anus, is the narrowest, and both ends are uniformly inclined and uniformly widened in an arc shape in the direction away from the blocking side 111, or the blocking portion 1111 gradually narrows in width from one end and then gradually widens to the other end. In the top view of the blocking member 11, both sides of the blocking member 11 along the width direction are curves that are concave toward the center of the blocking member 11, so as to avoid the buttocks on both sides of the anus, making it easier for the blocking side 111 to pass between the two buttocks and contact the anus.

[0059] In another embodiment of the present application, Figure 6As shown, along the length direction of the blocking member 11, the two ends of the blocking portion 1111 are wide, and the middle part is narrow. The blocking portion 1111 is not symmetrical. It can be understood that the narrow part fits the anus to block the anus, and the narrow part is short from the end located in the front side of the anus, and long from the end located in the back side of the anus. The end of the blocking portion 1111 located in the back side of the anus gradually becomes flat until it merges with the buttocks 1112 to form a plane similar to that. That is to say, the width and length of the end of the blocking portion 1111 located in the front part of the anus are both smaller than the width and length of the end of the blocking portion 1111 located in the back part of the anus. And the curvature of the narrow part of the blocking portion 1111 toward the front end is more curved than the curvature toward the rear end, or the radius is smaller, so as to better fit the anus and the human body curves before and after the anus. At this time, the blocking portion 1111 is only the most protruding part relative to the buttocks 1112 on the circumferential side, and it is not the most protruding part if the blocking member 11 is viewed as a whole.

[0060] Furthermore, if Figure 5 In some embodiments of the present application, the two ends of the buttocks 1112 are raised along the width direction of the blocking member 11, so that the two side edges of the blocking member 11 along the width direction can abut against the buttocks, ensuring a good blocking effect on both sides of the blocking member 11.

[0061] It is understandable that in order to ensure a good blocking effect and to ensure the comfort of the patient as much as possible, the material of the blocking member 11 needs to be soft and have a large elastic deformation. When gas or contrast agent or other fillers are input into the patient's intestine, there may be a certain amount of liquid in the excrement that the patient is stimulated to discharge from the anus. In order to prevent the liquid from flowing out along the outer wall of the catheter 20 or the gap between the buttocks and the blocking side 111, the material of the blocking member 11 also needs to have good water absorption. Therefore, the material of the blocking member 11 can be a sponge material, a rubber or silicone material with an absorbent pad on the blocking side 111, etc., as long as it can ensure that the blocking member 11 is soft, has a certain amount of elastic deformation, and the blocking side 111 has good water absorption.

[0062] It is understandable that when the blocking member 11 is blocking the anus, the medical staff will certainly apply a blocking force to the blocking member 11 to make it close to the anus. When the material of the blocking member 11 is relatively soft, even if the shape of the blocking side 111 does not strictly follow the curve near the human anus, or the shape of the blocking side 111 is similar to the curve near the human anus, it will fit closely to the anus and the buttocks around the anus under the action of the blocking force. Therefore, the shape of the blocking side 111 of the present application is similar to the curve near the human anus.

[0063] Since the blocking member 11 is relatively soft and has a strong elastic deformation ability, if the supporting side 112 is directly given abutting force by hand, since the area of ​​the palm is smaller than the area of ​​the supporting side 112, the part of the supporting side 112 that fits the hand is likely to be accommodated by the elastic deformation of the supporting side 112, which not only reduces the abutting force acting on the blocking side 111, but also makes the abutting force unevenly distributed on the blocking side 111, so that the blocking side 111 cannot obtain a good blocking effect.

[0064] In order to solve the above problems, in some embodiments of the present application, Figures 5 to 9 As shown, the child enema radiography auxiliary device 10 also includes a support member 12, which is covered on the support side 112. The hardness of the support member 12 is greater than the hardness of the blocking member 11. Applying abutment force to the support member 12 can make the support member 12 support the blocking member 11 to maintain abutment with the anus and the buttocks around the anus. When the medical staff directly gives a thrust to the support member 12 by hand, the support member 12 can evenly apply the force to the support side 112, so that the blocking side 111 obtains a uniform abutment force, ensuring a good blocking effect.

[0065] Since the blocking member 11 is relatively soft and highly plastic, it is very likely to be deformed under the action of gravity, and the support member 12 can ensure that the blocking member 11 maintains its proper shape, making it convenient for medical staff to operate the blocking member 11 to fit the patient's buttocks.

[0066] It is understandable that the support member 12 has the ability to support, so the support member 12 needs to have a certain strength. Therefore, in the embodiment of the present application, the support member 12 is made of a relatively hard material, such as compressed sponge, relatively hard rubber or relatively hard plastic.

[0067] In some embodiments of the present application, Figure 6-7 As shown, the support side 112 can be a plane or a curved surface, and the shape of the support member 12 follows the shape of the support side 112. When the support side 112 is a plane, it is convenient to store the child enema radiography examination auxiliary device 10, and when the support side 112 is a curved surface, it is convenient for medical staff to transfer the supporting force of the support member 12 to the blocking side 111, so that the blocking side 111 is evenly stressed.

[0068] Since the catheter 20 is inserted into the tube inlet hole 113, the position of the child enema contrast examination auxiliary device 10 on the catheter 20 needs to be adjusted during the process of inserting the insertion end 22 of the catheter 20 into the patient's intestine or after the insertion end 22 of the catheter 20 is inserted into the patient's intestine, so that the blocking member 11 can well block the anus. Therefore, there is a certain gap between the catheter 20 and the tube inlet hole 113, and the two are clearance-matched. Then it may cause the child enema contrast examination auxiliary device 10 to shift, so that the gas or contrast agent and other fillers input into the patient's intestine are discharged from the anus and flow along the tube inlet hole 113 until they leave from the support side 112, affecting the effect of the child enema contrast examination auxiliary device 10 in blocking the anus.

[0069] In order to solve this problem, in some embodiments of the present application, Figure 8 As shown, a sealing plug 13 is provided at the inlet hole 113 away from the blocking side 111, and the sealing plug 13 is used to movably seal the catheter 20 that passes through the inlet hole 113. The child enema contrast examination auxiliary device 10 is prevented from shifting, thereby preventing the gas or contrast agent and other fillers from leaving the end of the inlet hole 113 located at the support side 112 to ensure the sealing effect. And the sealing plug 13 can slide along the catheter 20. It can be understood that during the process of inserting the catheter 20 into the patient's intestine or after the catheter 20 is inserted into the patient's intestine, the child enema contrast examination auxiliary device 10 is not necessarily at a position that abuts against the anus. At this time, it is necessary to adjust the position of the child enema contrast examination auxiliary device 10 on the catheter 20, and the sealing plug 13 will not limit the position of the catheter 20, so that the position adjustment between the child enema contrast examination auxiliary device 10 and the catheter 20 can be achieved.

[0070] Specifically, the sealing plug 13 has a through hole that cooperates with the pipe inlet hole 113, and multiple fan-shaped shielding pages are centered on the center of the through hole. The arc edges are connected to the boundaries of the through hole, and the side surfaces are abutted and covered on the through hole in turn. The catheter 20 passes through the through hole, and the shielding pages abut against the catheter 20 to seal the catheter 20 and the through hole.

[0071] In other embodiments of the present application, Fig. 9As shown, the child enema radiography auxiliary device 10 also includes a sealing layer 14, which is located on the side of the support member 12 away from the blocking member 11. The sealing layer 14 is provided with a sealing hole adapted to the catheter 20, and the catheter 20 can be inserted into the sealing hole and abut against the sealing layer 14. Specifically, the radius of the sealing hole is smaller than the radius of the catheter 20, and the catheter 20 and the sealing hole are interference fit, so that the hole wall of the sealing hole abuts against the catheter 20 to achieve a good sealing effect. The sealing layer 14 can be made of rubber or soft plastic material. Since the sealing layer 14 is soft in texture and has a large elastic deformation, it can follow the blocking member 11 to move along the catheter 20 and ensure good sealing. Secondly, since the rubber material or soft plastic has a good feel, it also allows medical staff to obtain a good touch during operation.

[0072] Although the sealing layer 14 or the sealing plug 13 mentioned above can play a certain role in preventing the relative movement of the child enema contrast examination auxiliary device 10 on the catheter 20 when abutting against the catheter 20, they cannot play a fixing role. Therefore, in some embodiments of the present application, the child enema contrast examination device also includes a fixing member 15, which is located on the side of the support member 12 away from the blocking member. When the blocking member 11 is adjusted to the required position on the catheter 20, the fixing member 15 can fix the support member 12 and the catheter 20 to prevent the child enema contrast examination auxiliary device 10 from moving relative to the catheter 20. When the catheter 20 is inserted to the required position in the intestinal tract of the child, the position of the child enema contrast examination auxiliary device on the catheter 20 is moved to abut against the anus of the child to ensure a good blocking effect on the anus. The fixing member 15 can be used to fix the support member 12 or the sealing layer 14 to the catheter 20, which is convenient for the operability of inputting the filling material into the intestinal tract of the child and improves the probability of successful one-time filling. The fixing member 15 may be a non-stick adhesive, and may be a plurality of non-stick adhesives that fix and adhere the side of the enema contrast auxiliary device away from the blocking member 11 to the catheter 20. Of course, in order to further prevent the enema contrast auxiliary device 10 from moving, the periphery of the enema contrast auxiliary device 10 may also be adhered to the buttocks of the child with non-stick adhesive to fix the enema contrast auxiliary device 10.
