Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and specifically relates to a novel enema injection device. Background Art

[0002] Suppositories are lubricants, mainly composed of glycerin and other auxiliary drugs. Suppositories are usually used clinically to stimulate the intestinal wall to induce defecation reflex to assist defecation. However, ordinary suppositories are usually packaged in a semi-open container with a long neck at the front end, and a sealing cap is installed at the end of the long neck. When using, the sealing cap is removed, and then the long neck is directly inserted into the anus for medication.

[0003] However, in actual use, medical staff found that there are still the following inconveniences:

[0004] 1) The drug delivery device is an integrated design. Elderly patients who are bedridden for a long time need a large amount of enema each time. After using one, a new one must be inserted again. Repeated insertion increases the pain of the patient and the workload of medical staff.

[0005] 2) The mouth of the enema bottle is limited in length and cannot reach deeper into the rectum;

[0006] 3) The long neck at the end can easily cause damage to the anus and intestinal wall;

[0007] 4) When the drug delivery device is pulled out, the feces, urine, and liquid medicine in the patient's body will flow out, increasing the workload of medical staff. Utility Model Content

[0008] In view of this, the utility model provides a novel enema injection device to solve the technical problems existing in the above-mentioned background technology.

[0009] The technical solution adopted by the utility model is as follows:

[0010] A novel enema injection device comprises a syringe and a hose, wherein one end of the hose is a closed end and the other end is an open end; the open end of the hose is detachably connected to the syringe, the closed end of the hose is a hemispherical structure, and a plurality of liquid outlet holes are arranged on the hose body near the closed end.

[0011] By adopting the above technical solution, the drug dispenser adopts a split structure. For elderly patients who need a large amount of enema each time, after using one, there is no need to pull out the hose, but only need to replace the syringe containing the enema to avoid repeated insertion, thereby reducing the patient's pain and the workload of medical staff; the closed end of the hose is a hemispherical structure, which can avoid damage to the anus and the inner wall of the rectum during the insertion of the hose head; the length of the hose can be selected according to actual conditions so that it can reach deeper into the rectum.

[0012] As a further preferred embodiment, the open end of the hose is threadedly connected to the syringe. The threaded connection structure is simple in structure and easy to operate.

[0013] Preferably, the hose is sleeved with an adsorption ring pad that can move along the direction of the hose body. When the hose is withdrawn from the patient's anus, the medical staff moves the adsorption ring pad along the direction of the hose to the patient's anus to make it close to the patient's skin. The adsorption ring pad can absorb the feces, urine and liquid medicine brought out by the hose, avoiding the medical staff from cleaning twice and reducing the workload of the medical staff.

[0014] Preferably, the syringe includes a syringe barrel, a piston head and a push rod, one end of the push rod is rotatably connected to the piston head; an end cap is fixedly provided at the end of the syringe barrel, and the push rod passes through the end cap and is threadedly matched with the end cap. When the patient uses a small amount, some enema remains in the syringe, which is directly discarded, wasting medical resources. The device makes the piston head's advancement length controllable by screwing the push rod in. After one use, the syringe is separated from the hose, and the hose that has been in contact with the anus is discarded. The enema in the syringe will not leak out under the action of atmospheric pressure, so it can be fully utilized in multiple times, thereby improving the utilization rate of the enema and saving resources.

[0015] As a further preference, a through hole is provided in the middle of the end cover, an internal thread is provided in the through hole, and an external thread matching the internal thread is correspondingly provided on the push rod.

[0016] As a further preferred embodiment, an annular handle is fixedly disposed on one end of the push rod away from the piston head, so that medical personnel can control the push rod to rotate by rotating the annular handle, and the operation is simple.

[0017] Preferably, the front end of the syringe is a connector, and a one-way valve is provided on the connector to prevent the suppository in the hose from flowing back into the syringe.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] 1) The drug delivery device adopts a split structure. For elderly patients who need a large amount of enema each time, after using one, there is no need to pull out the hose. Instead, only the syringe containing the enema needs to be replaced to avoid repeated insertion, thereby reducing the patient's pain and the workload of medical staff. The closed end of the hose is a hemispherical structure, which can avoid damage to the anus and the inner wall of the rectum during the insertion of the hose head.

[0020] 2. When the hose is pulled out from the patient's anus, the medical staff will move the adsorption ring pad along the direction of the hose to the patient's anus, so that it is close to the patient's skin. The adsorption ring pad can absorb the feces, urine and liquid medicine brought out by the hose, avoiding secondary cleaning by medical staff and reducing their workload.
