Description

Technical Field

[0001] The present invention relates to the technical field of measuring uterine bleeding in obstetrics and gynecology, and particularly relates to a device for observing, measuring and processing uterine bleeding. Background Art

[0002] In obstetrics and gynecology, after operations such as vaginal delivery, cesarean section, and induced abortion, it is necessary to observe the uterine bleeding condition of parturients or patients to facilitate timely treatment of parturients or patients with excessive postpartum bleeding. Postpartum hemorrhage refers to the vaginal blood loss exceeding 500 ml within 24 hours after the fetus is delivered, commonly known as postpartum massive hemorrhage or postpartum blood collapse. The incidence of postpartum hemorrhage accounts for 2%-3% of the total number of deliveries. Due to the large subjective factors in measuring and collecting blood volume, the estimated blood loss is usually only half of the actual blood loss, so the actual incidence is higher.

[0003] Currently, the evaluation methods for postpartum hemorrhage generally include visual estimation method, weighing method, area method, volumetric method, shock index method, hemoglobin calculation method, etc.

[0004] 1. Visual estimation method: Estimate the postpartum blood loss according to the clinical experience of midwives. This estimation method is simple and convenient, but the accuracy is very low, resulting in the neglect of some acute massive bleeding situations.

[0005] 2. Weighing method: During and after childbirth, in case of vaginal bleeding, dressings, gauzes, etc. are needed to compress and stop bleeding. Weigh the used gauzes and dressings, and then subtract the original weight. The obtained difference is the approximate blood loss. There are also certain errors in this estimation method.

[0006] 3. Area method: Immerse 10 ml of blood in a dressing. The area of the soaked dressing is used as a standard, and then estimate the postpartum blood loss according to the number of postpartum dressings and the area of the blood-soaked dressing. This method is not complicated to operate clinically and has certain reference significance.

[0007] 4. Volumetric method: Use a special container with scales to collect blood and directly read the volume value, which belongs to an intuitive measurement method. This method has high accuracy in the laboratory environment, but the actual clinical operation may be affected by the mixing of blood and amniotic fluid or incomplete absorption of dressings.

[0008] 5. Shock index method: Judge the degree of blood loss through the ratio of heart rate / systolic blood pressure: SI = 0.5 is the normal range; SI = 1.0, the blood loss is about 500 - 1500 ml; SI = 1.5, the blood loss is about 1500 - 2500 ml; SI ≥ 2.0, the blood loss exceeds 2500 ml; This index has important clinical significance for the early identification of acute massive bleeding.

[0009] 6. Hemoglobin calculation method: The amount of bleeding is judged by measuring the hemoglobin levels before and after childbirth. When the hemoglobin of the parturient drops by 10 g / L, the amount of bleeding is between 400 - 500 ml. However, due to blood concentration, the hemoglobin calculation method cannot accurately determine the amount of postpartum bleeding either.

[0010] The above methods all have defects such as troublesome blood collection, inaccurate measurement of the amount of bleeding, and the inability to detect and treat rapid massive bleeding of patients in a timely manner. Summary of the Invention

[0011] The purpose of the present invention is to provide a uterine bleeding observation, measurement and treatment device that can observe the dynamic situation of uterine bleeding in real time, accurately measure the amount of bleeding, make an early diagnosis of postpartum massive bleeding, and promptly administer drugs for treatment.

[0027] In order to better achieve the above-mentioned invention purpose, the present invention can further include the following technical solutions:

[0028] A warning tube operation cap is provided at the rear end of the bleeding warning tube.

[0029] To better achieve the above-mentioned invention object, the present invention may further include the following technical solutions:

[0030] A pair of underpants is sleeved outside the rear end of the support plate, and through holes corresponding to and respectively cooperating with the collection hole, the observation hole, and the treatment hole are arranged at corresponding positions of the underpants.

[0031] The usage method of the above-mentioned uterine bleeding observation, measurement, and treatment device is generally as follows:

[0032] Put the blood collection head into the vaginal dilator in advance, and then its rear end extends out from the corresponding through hole of the sealing bottom plate.

[0033] After a parturient or a patient undergoes cesarean section, normal delivery, induced abortion, or other surgeries, the cervical canal connecting ring is sleeved on the outer wall of the cervical canal to the vaginal fornix. Open the air suction connecting nozzle and connect it to the air extraction pump. Start the air extraction pump to extract the air inside the cervical canal connecting ring, and the negative pressure suction cup adsorbs to the outer wall of the cervical canal. Separate the air suction connecting nozzle from the air extraction pump and seal the air suction connecting nozzle at the same time, then turn off the air extraction pump.

[0034] Insert the two side ends of the support plate between the two connecting pieces and the sealing bottom plate respectively. Let the rear end of the blood collection head extend out from the collection hole of the support plate, and thread-connect it to the collection tube at the rear end. Then screw the positioning nut to the front end to press the inverted frustum-shaped middle part of the blood collection head against the side wall of the collection hole, playing a role in sealing and positioning.

[0035] Then put the underpants on the patient. The corresponding through holes of the underpants correspond to the collection hole, the observation hole, and the treatment hole one by one; it can better limit the positions of the vaginal dilator and the cervical canal connecting ring, and avoid the vaginal dilator and the cervical canal connecting ring falling off during the process of carrying the parturient or the patient back to the ward after the surgery.

[0036] Then insert the sealing plug and the bleeding warning tube into the treatment hole to connect the injection treatment and the rapid bleeding warning parts; connect the collection tube to the connecting hose to connect the blood collection part; insert the observation operation tube into the observation hole to connect the observation part; then the work of observing and collecting the uterine bleeding condition of the parturient or the patient can start; during the process of carrying the parturient or the patient back to the ward, the medical monitor, the bleeding warning tube, the connecting hose, the observation operation tube and other parts can also be disconnected or removed, and the corresponding holes are sealed with appropriate sealing plugs, and the end of the collection tube is sealed with an appropriate sealing cap, which is convenient for carrying and / or avoiding the medical monitor from slipping and breaking from the moving hospital bed; after the patient arrives at the ward, then connect all the pipes.

[0037] Through the medical high-definition camera, it is convenient to see the situation of uterine bleeding entering the blood collection and observation cavity; such as the change of the cervical os, whether there is blood flowing out of the cervical os, the bleeding speed, and a rough estimate of the blood volume.

[0038] After uterine bleeding enters the blood collection observation cavity, the blood can flow from the blood collection head, collection tube, and connecting hose into the blood metering bucket; it is convenient to see the amount of bleeding when the blood enters the blood metering bucket; it is convenient to collect all the uterine bleeding, and the blood metering is accurate;

[0039] When it is observed that there are blood clots in the blood collection observation cavity, the blood flow is not smooth or the flow is stagnant, start the vacuum pump to suck out the blood clots to ensure that the blood in the blood collection observation cavity can flow into the blood metering bucket in time;

[0040] When it is observed from the outside that the patient's abdomen bulges, and the internal high-definition camera observes that the cervix is closed or blocked, consider that the blood or blood clots in the uterus cannot be discharged smoothly, and the continuous bleeding blood and / or blood clots in the uterus cause the uterus to swell. Loosen the positioning nut to the rear end of the collection tube, hold the collection tube, and with the help of the high-definition camera and medical monitor, insert the blood collection head into the uterus, start the vacuum pump, and perform negative pressure suction on the blood or blood clots in the uterus until no blood or blood clots flow out of the transparent collection tube and connecting hose;

[0041] When it is observed through the high-definition camera that the uterus contracts poorly or the cervix does not contract, resulting in bleeding, pull out the sealing plug, insert the injection needle from the treatment hole, and inject a small amount of oxytocin or Hemabate and other drugs on the outer wall of the cervix;

[0042] When the bleeding is fast and the blood quickly enters the blood collection observation cavity and cannot be quickly discharged, resulting in the liquid level rising rapidly to the position of the liquid level elevation sensing probe, the medical monitor will quickly sound an alarm, reminding the parturient or patient of rapid bleeding or massive bleeding, and can provide timely treatment to the patient at the first time, avoiding the situation that massive bleeding cannot be detected and treated in time by traditional metering methods, resulting in life-threatening situations for the parturient or patient;

[0043] When the blood in the blood metering bucket reaches 400 ml and / or 500 ml, the liquid level metering sensing probe sends a signal to the medical monitor, and the medical monitor quickly sounds an alarm, reminding the parturient or patient that the amount of bleeding has reached the situation where blood transfusion treatment or other treatments are required;

[0044] When it is necessary to observe the change in the diameter of the cervical orifice, insert the blood collection head into the uterus to aspirate blood or blood clots, inject drugs into the cervical canal, etc., the ventilation connection nozzle at the rear end of the vaginal dilator can be connected to an air pump. The air pump is started to inflate the inside of the vaginal dilator with air. The inflated outer wall of the vaginal dilator expands outward to dilate the vagina, and the inner wall straightens due to inflation to form a cylindrical blood collection and observation cavity. The ventilation connection nozzle is separated from the air pump and the ventilation connection nozzle is closed at the same time, and the air pump is turned off; thus, the above operations can be conveniently carried out; when the above operations are not carried out, the vaginal dilator can be not inflated or insufficiently inflated to avoid the outer wall of the vaginal dilator forming an outward expansion force on the vaginal wall for a long time, resulting in uncomfortable symptoms on the vaginal wall.

[0045] In summary, the advantages of the present invention are as follows: The uterine bleeding observation, measurement and treatment device of the present invention is convenient to use, can observe the bleeding condition inside the blood collection and observation cavity and the change condition of the cervical orifice part in real time, can collect and measure all uterine bleeding, the bleeding condition and blood measurement are accurate. When there are situations such as poor blood flow, inability to smoothly discharge the blood inside the uterus, the uterine bleeding amount approaching or reaching a dangerous value, poor or no uterine contraction, rapid massive uterine bleeding, etc., the parturient or patient can be treated and quickly rescued in the first time, and the situation endangering the life of the patient can be effectively avoided.
